The Anonymous Widower

Future Stansted Airport Train Services

Currently, the following services go to Stansted Airport station, in trains per hour (tph)

  • Four tph – Stansted Express – Liverpool Street
  • One tph -CrossCountry – Birmingham New Street via Cambridge, Peterborough and Leicester
  • One tph – Greater Anglia – Cambridge via Audley End and Whittlesford Parkway

Greater Anglia have plans to change the services.

  • Extend the Norwich and Cambridge service to Stansted Airport.
  • Reintroduction of a Stansted Express service between the Airport and Stratford is mentioned in Wikipedia.

With two very long and one shorter platform, the Airport station has plenty of capacity.

Stansted Express Journey Times And Trains Required

Currently, Stansted Express services run at a frequency of four tph, that take fifty minutes between London and the Airport.

If a turnround time of ten minutes is added, then it takes trains two hours to do a round trip between London and the Airport.

So this means that thse numbers of trains are needed for the following frequencies.

  • One tph – Two trains
  • Two tph – Four trains
  • Four tph – Eight trains

As Greater Anglia have ordered ten Class 745/1 trains for Stansted Express, these would be able to provide a reliable service with eight in service, one as a spare and one in maintenance.

A Stansted Express service to Stratford would take the same time and would need similar numbers of trains.

Norwich and Stansted Airport Journey Times And Trains Required

The timing for the proposed service between Norwich and Stansted Airport, can be estimated by taking the timing of current services.

  • Norwich and Cambridge – One hour 20 minutes
  • Cambridge and Stansted Airport – 30 minutes

Both services are run by reasonably-modern 100 mph diesel trains.

Add in a ten minute turnround at both ends of the route and it should be possible to schedule a Stansted Airport and Norwich round trip in four hours.

Greater Anglia is introducing new bi-mode Class 755 trains on this route.

  • The trains will be designed for fast stops.
  • The trains will run on electricity on the nearly forty miles between Stansted Airport and Ely and around Norwich.
  • The trains will run on diesel between Ely and Trouse Junction, just to the South of Norwich.
  • The trains will probably be abe to achieve 100 mph on a good proportion of the route.
  • The trains will probably be four-cars.

It would need four trains to run the proposed one tph service.

The current Norwich and Cambridge service probably needs three trains, so extending to Stansted Airport will need an extra train.

This seems to be good value for passengers, the Cities of Cambridge and Norwich, Stansted Airport and Greater Anglia.

Could There Be A Norwich And London Service Via The West Anglia Main Line?

I can remember seeing steam-hauled expresses thundering between Liverpool Street and Norwich in the 1950s, through places like Brimsdown.

They are long gone, but they gave places like Wymondham and Thetford a direct rail link to London.

Greater Anglia’s future plans will connect these towns and others directly to Stansted Airport, but could they go all the way to London?

What do the mathematics show?

The section timings of a Norwich and London service via Cambridge and Stansted Airport would be as follows.

  • Norwich and Cambridge – One hour 20 minutes
  • Cambridge and Stansted Airport – 30 minutes
  • Stansted Airport and London – 50 minutes

This is just two hours and forty minutes.

Add in a few minutes for the reverse at Stansted Airport and the turnround at either end and I believe a round trip could be comfortably within six hours.

It would therefore mean that six trains would be needed to run an hourly service between London and Norwich.

  • Stops could be Tottenham Hale, Broxbourne, Harlow Town, Bishops Stortford, Stansted Airport, Audley End, Whittlesford Parkway, Cambridge, Cambridge North, Ely and all stations to Norwich.
  • The London terminal could be Liverpool Street or Stratford.
  • If Stratford were to be used, trains could be turned round in the High Meads Loop.
  • Trains would be Class 755 trains, which are bi-mode and capable of 100 mph running.
  • Between London and Ely, the trains would take advantage of the electrification.

The service would give a lot of stations a direct connection to Stansted Airport, that would be complimentary to the Stansted Express.

It would require just two more trains, than the planned Norwich and Stansted Airport service.

The advantages of the service would be.

  • Stations between Thetford and Norwich would get direct London and Stansted Airport services.
  • Stratford would get a very useful direct service to Stansted Airport.

Greater Anglia would serve two markets with the extended service and just two extra trains, over the planned service.

If Greater Anglia say a London and Norwich via Stansted Airport service will never happen, they are being economical with the truth.

Could Class 755 Trains With Batteries Bridge The Electrification Gap,Between Ely And Trowse Junction?

The distance between the electrification at Ely station and Trowse Junction, South of Norwich, is just under fifty-three miles.

I believe that the tri-mode four-car Flirts for Trains for Wales are similar to Greater Anglia’s Class 755 trains, with three of the Deutz diesel engines replaced with 100-120 kWh batteries.

Would this be enough power to take the train across the electrification gap?

Consider.

  • There is electrification at both ends and the batteries could be full, on entering the unelectrified section.
  • The route is very gentle.
  • There are a few stops, but the trains will have regenerative braking to charge the batteries.
  • The trains could retain a single diesel-engine,, should livestock on the line cause the service to be suspended.

For these and other reasons, I suspect that in a couple of years, diesel will be relegated to emergency use only between Norwich and Stansted Airport.

The Herd Of Wannabe Unicorns In The Room

Other places have elephants, but the City of Cambridge has herds of wannabe unicorns.

For those of you, unfamiliar with the term, Wikipedia defines unicorn like this.

A unicorn is a privately held startup company valued at over $1 billion.

Cambridge is expanding at a fast rate and it needs public transport systems to bring in the workers, visitors and investors.

  • A new Cambridge North station has been built.
  • A guided busway linking Addenbrooke’s and Papworth Hospitals and the Cambridge Biomedical Campus to the City Centre has been built.
  • A new Cambridge South station is being planned.
  • The East-West Rail Link will connect Cambridge to Oxford.

Road travel in the local area is not an option.

Currently, most rail services radiate from Cambridge station, but like London and other cities are proving, Cambridge needs Cross-City services.

A high-frequency North-South route is being created  across the City.

  • To the North of the City is Ely station.
  • North of Ely station, lines fan out to Peterborough, Kings Lynn and Norwich.
  • From North to South across the City, there will be Waterbeach, Cambridge North, Cambridge and Cambridge South  stations.
  • South of Cambridge South station, lines will fan out to Bedford and Oxford, Royston, Hitchin and Kings Cross and Audley End, Stansted Airport and Livepool Street.

In addition routes to Bury St. Edmunds, Ipswich and Felixstowe reach out to the East.

The current North-South train services include.

  • 1 tph – Birmingham New Street and Stansted Airport
  • 1 tph – Kings Lynn and Kings Cross
  • 1 tph – Cambridge and Norwich
  • 2 tph – Cambridge and Brighton
  • 2 tph – Cambridge and Liverpool Street
  • 2 tph – Cambridge and Kings Cross

The number of these services will grow.

Will More Stations Be Built Or Reopened Between Stansted Airport And Norwich?

I know the route, South of Cambridge better than I know it to the North.

To the South of Cambridge, the current stations could be sufficient, with improved car and bicycle parking and provision for electric cars.

To the North, there appear to be new housing developments under consideration and surely, these will need good public transport to and from Cambridge.

Does The Norwich and Stansted Airport Service Need Two Trains Per Hour?

I have a feeling that Greater Anglia think, that East Anglia’s generally one tph services between major towns and cities is not enough.

Greater Anglia have said they will do the following.

  • Increase the Ipswich and Norwich frequency from two to three tph.
  • Run two tph between Ipswich and Kennett via Bury St. Edmunds.

I talked previously about Cambridge and its  herd of wannabe unicorns.

I believe strongly, that the Cambridge Effect will in a couple of years, mean that the frequency between Norwich and Stansted Airport will need to be doubled.

But will Greater Anglia have enough trains?

Greater Anglia are  purchasing a fleet of 38 Class 755 trains with a total of 138 carriages to replace 27 assorted trains with a total of 58 carriages.

  • This is a forty percent increase in the number of trains.
  • This is nearly two and a half times as many carriages.
  • The average number of carriages per train is raised from 2.1 to 3.6.

That is a massive increase in train capacity.

There should be enough for either.

  • Eight trains for two tph between Norwich and Stansted Airport.
  • Twelve trains for two tph between Norwich and London via Stansted Airport.

These would be increases of four and eight trains respectively on Greater Anglia’s  current plan for a one tph service between Norwich and Stansted Airport.

Conclusion

Greater Anglia have enough trains to run a two tph service between Norwich and London via Stansted Airport.

I believe that the Cambridge Effect will create enough demand to necessitate expansion of the proposed one tph service between Norwich and Stansted Airport into a Norwich and London via Stansted Airport service.

  • Frequency will be two tph.
  • New commuter-friendly stations could be built.
  • The Southern terminal could be Stratford to give a second route to Stansted Airport from London.

Greater Anglia would be satisfying two markets with one train.

Tottenham Hale Station Is Beginning To Make Sense

These are pictures, I took of Tottenham Hale station, this morning.

A few of my observations.

The Cladding Is Going On

The cladding is going on the building above the Victoria Line ticket hall.

It appears to be fireproof glass on a concrete and steel frame.

A Wide Island Platform

Platforms 2 and 3 form a wide island platform.

  • Only Platform 3 appears to be in use for London-bound services to both Liverpool Street and Stratford.
  • Both faces appear long enough for a 240 metre long Stansted Express train.
  • There is a step-free bridge at the half-way point of the platform.
  • The original bridge with its escalator is still in place.

It is a design with good potential for handling more services.

  • Platform 3 could handle all services to Liverpool Street station.
  • Platform 2 could handle all services to Stratford station.

Travellers would just walk across the island platform.

The Step-Free Bridge Appears Almost Complete

The bridge appears to be almost complete.

  • The bridge has lifts and stairs with double handrails on both sides.
  • The lift and stairs on the London-bound side are in the middle of the island platform 2 & 3.
  • There is an escalator for London-bound travellers to access the bridge, to give an easy route to the Victoria Line.

There appears to be just a bit of testing before full commissioning.

The Old Bridge Is Still In Place

It still has its up escalator from Platform 2 & 3 and there have been statements that this bridge will be modified to create a link between the Underground station and the developments on the other side of the tracks.

Most Of The Bus And Taxi Interchange Is Complete

With buses and black taxis, the interchange seems finished.

  • Much of North and East London can get a bus to and from the station.
  • Today, I got a 76 bus to Dalston for a two hundred metre walk.
  • But with a heavy case, I’d get a black cab,

Transport planners usual only plan for travellers to and from the City centre.

The Future

The Stratford And Meridian Water Shuttle

This is rumoured to start in September and will probably be the following.

  • Two trains per hour (tph) between Stratford and Meridian Water stations.
  • Stops will be at Lea Bridge, Tottenham Hale and Northumberland Park stations.
  • Trains could be any length up to probably 240 metres, as all platforms are long.
  • Current trains take sixteen minutes between Stratford and Meridian Water stations.

In addition services between Stratford and Hertford East and Bishops Stortford stations would stop at Meridian Water, to give the station a four tph service to and from Stratford.

The new Meridian Water station has been built with a dedicated bay platform for the shuttle service.

The bay Platform 2 is on the right and the through Platform 3 is on the left in this picture taken looking North at Meridian Water station.

Two tph to Stratford would leave from each side of this platform.

The new track between Meridian Water and Lea Bridge stations has been built without a passing loop, so the two tph shuttle must probably be run by a single train.

The shuttle would.

  • Have exclusive use of the new track between Lea Bridge and Meridian Water stations.
  • Have shared use of the existing track between Lea  Bridge and Stratford stations.
  • Call at Platform 2 at Tottenhale and Northumberlan Park station in both directions.

A two tph shuttle would consist of the following.

  • Four journeys between Stratford and Meridian Water stations.
  • Twenty-four intermediate station stops.
  • Two turnrounds each at Meridian Water and Stratford stations.
  • Current turnrounds at Stratford have in excess of twenty minutes to unload and load passengers and for the driver to change ends.
  • Greater Anglia will be running the shuttle in September with nearly nearly forty-year-old British Rail-built Class 317 trains.

As there is not enough time to fit the trains with wings and jet engines, what the hell will be happening?

Go to Stratford station and there is an out-of-date sign at the end of Platform 1 and 2, where the Overground trains terminate.

It directs passengers to Platform 12 for Stansted Airport.

It dates from the time, when Stansted Express trains used to go to Stratford station.

They didn’t turnround in Platform 12, but used the High Meads Loop underneath the Eastfield Shopping Centre to reverse direction.

  • The train stopped in Platform 12 long enough for passenger to leave and join the train.
  • The driver stayed in the same cab and carried on driving.

I suspect that a Class 317 train could go from Platform 1 at Lea Bridge station, round the High Meads Loop and back to Platform 2 at Lea Bridge station, in these split times.

  • Lea Bridge to Stratford – 6 minutes.
  • Stop in Platform 12 at Stratford – 1 minute
  • Straford to Lea Bridge – 6 minutes.

I believe all these times can be achieved by well-driven Class 317 trains, which gives a timing of thirteen minutes.

Currently, Lea Bridge to Meridian Water takes nine minutes in the elderly Class 317 trains, sharing the track with other trains.

But the shuttle trains will have a clear track, once they are on the new track North of Lea Bridge station.

I believe they could do this in perhaps seven minutes.

Applying, the sort of maths a bright nine-year-old should be able to master.

60 – 2*13 – 4*7 = 6

So could you turn a train round at Meridian Water station in three minutes?

  • London Overground regularly do this at Dalston Junction station.
  • Stepping-up might be needed, where a second driver immediately gets into the rear cab and takes over the train.

But it all leads me to the conclusion, that a single Class 317 train can run a two tph shuttle between Meridian Water and Stratford stations.

The following conditions would apply.

  • The trains must use the High Meads Loop.
  • There would be a fast stop in Stratford, taking less than a minute.
  • Stratford to Lea Bridge times should be six minutes or less.
  • Meridian Water to Lea Bridge times should be seven minutes or less.
  • Stepping-up might need to be employed at Meridian Water.
  • Trains could be up to 240 metres long.
  • The trains would have to be well-driven.

There is also the fall-back position, that the new Class 720 trains to be delivered later in the year will have increased performance.

Development Of The High Meads Loop

The High Meads Loop is an almost unique piece of railway infrastructure on the UK rail network.

  • The simpler Wirral Line Loop under Liverpool turns upwards of twelve tph back for the Wirral Line.
  • The Wirral Line also has four stations on the loop.
  • I believe the High Meads Loop could easily handle a similar frequency to the Wirral Line Loop.
  • The High Meads Loop is also double-track.

I believe, that currently, the High Meads Loop is only planned to only handle the following services.

  • Two tph – Meridian Water Shuttle
  • Two tph – West Anglia Main Line services.

There is a lot more capacity to handle services from the West Anglia Main Line or its branches.

Liverpool Street And Meridian Water Services

When the Field Day Festival took place a couple of weeks ago, Greater Anglia stopped several services, including some Stansted Express services at Meridian Water station to bring festival-goers back to Central London.

Currently, the following Liverpool Street services pass through Meridian Water station.

  • Two tph – Liverpool Street and Hertford East
  • Two tph – Liverpool Street and Cambridge
  • Four tph – Stansted Express

As Greater Anglia’s new fleet of trains, will all be optimised for fast stops, I wouldn’t be surprised to see some Greater Anglia services to and from Liverpool Street station doing the following.

  • Northbound services would stop in Platform 4 at Tottenham Hale, Northumberland Park and Meridian Water stations.
  • Southbound services would stop in Platform 3 at Tottenham Hale, Northumberland Park and Meridian Water stations.

If Northumberland Park and Median Water stations deserve four tph to and from Stratford, surely they deserve the same frequency to and from Liverpool Street. Could both Cambridge and Hertford East services stop at Northumberland Park and Meridian Water station?

  • Both Northumberland Park and Meridian Water stations could get direct services to and from Liverpool Street station.
  • The island platforms at all three stations  could give some useful cross-platform interchanges.

Stations North of Tottenham Hale would get these frequencies to and from the station and the Victoria Line.

  • Eight tph – Northumberland Park
  • Eight tph – Meridian Water
  • Two tph – Ponders End
  • Two tph – Brimsdown
  • Four tph – Enfield Lock
  • Three tph – Waltham Cross
  • Six tph – Cheshunt
  • Six tph – Broxbourne

Note.

  1. With a few extra stops by Stratford services, all stations between Tottenham Hale and Broxbourne could get at least a very customer-friendly four tph.
  2. If your station didn’t have a Stratford service, there would be a cross- or same-platform interchange going at Tottenham Hale station.
  3. Using Stratford and Crossrail may be preferable on some journeys than Tottenham Hale sand the Victoria Line.
  4. In this hot weather give me an air-conditioned Aventra over a furnace on the Victoria Line any time.

A Lea Valley Metro could be emerging.

Stansted Express And Meridian Water

Consider.

  • Various arguments and statistics could be used to decide whether Stansted Express trains stopped at Meridian Water station.
  • I suspect too, that if Spurs continue to play in Europe, that a strong case can be made for stopping Stansted Expresses at Northumberland Park station.
  • But the performance of the trains on the West Anglia Main Line will enable Greater Anglia to do what’s best for passengers and profits.

As Greater Anglia did a couple of weeks ago with the Field Day Festival, they can even be selective.

Stansted Express And Stratford

The Stansted Express is currently a four tph service between Liverpool Street and Stansted Airport.

Consider.

  • In the past, Stansted Expresses ran to and from Stratford.
  • As they did in the past, they could terminate in the High Meads Loop at Stratford.
  • Big International events are held at Stratford.
  • The Central Line links Stratford and Liverpool Street.
  • Crossrail will link Stratford and Liverpool Street at a frequency of twelve tph.
  • Stratford and Tottenham Hale will soon be linked at a frequency of four tph.
  • Extra trains could be needed to run Stansted Expresses to and from Stratford.

I think that running a Stansted |Express to and from Stratford that will remain under review and could be implemented at some date in the future.

In Future Stansted Airport Train Services, I outline how trains might serve Stansted Airport from Norwich and Stratford stations.

Any trains between Stratford and Stanstead Airport, would probably terminate in the High Meads Loop, as they did in the past.

Should High Meads Loop Services Use Platform 11 Or Platform 12?

When Stansted Express services used the High Meads Loop a few years ago, they used to use Platform 12, as the sign still shows.

It could obviously handle the planned four tph, but suppose the High Meads Loop was handling twelve or sixteen tph, as a high-frequency route to Crossrail would Platform 11 be a better option?

Certainly, if the High Meads Loop was handling a lot of services including Stansted Express, Cambridge and local services, there would need to be a lot of thought about how to organise passengers.

There would need to be a fast pedestrian route between Platform 11 or 12 and the two Crossrail/Central Line platforms.

Extra Services That Could Use The High Meads Loop

As I said earlier, I think that if a Stratford and Stansted Airport service is revived, it will use the High Meads Loop.

My preference would be to run a Stratford and Norwich service, that would call at Stansted Airport.

  • It would serve greatly increase capacity all along the West Anglia Main Line, through Cambridge.
  • It could give intermediate stations a direct service to Stansted Airport.
  • Two tph would be a sensible frequency.
  • Calls could include Tottenham Hale, Broxbourne, Harlow, Bishops Stortford, Whittlesford Parkway, Cambridge, Cambridge North, Ely and all stations to Norwich.

A two tph service would need twelve Class 755 trains.

The High Meads Loop would also be available to turn extra local services.

One possibility is to reinstate the Hall Farm Curve and run services between Chingford and Stratford.

The level crossing at Highams Park station is a problem, but in Improving The Chingford Branch Line, I outlined how it could be possible to run four tph between Chingford and Stratford stations, using clever timetabling, digital signalling and good driver aids.

Another possibility is to terminate some London Overground services from Cheshunt and Enfield Town at Stratford, instead of Liverpool Street.

Services could be .

  • Two tph between Enfield Town and Liverpool Street
  • Two tph between Cheshunt and Liverpool Street
  • Two tph between Enfield Town and Stratford.
  • Two tph between Cheshunt and Stratford.

This would mean.

  • London Overground’s preferred frequency of four tph to Enfield Town and Cheshunt.
  • All stations between Edmonton Green and Seven Sisters, including White Hart Lane, would get an eight tph service to London and Crossrail.
  • Four tph in both directions would call at South Tottenham station to give a same platform interchange with the Gospel Oak to Barking Line..

Most of the infrastructure is already in place, although improvements might be needed to the Seven Sisters Chord, that links Seven Sisters station to the Gospel Oak to Barking Line.

Summing up, I believe we could see the following services using the High Meads Loop.

  • Two tph to and from Meridian Water
  • Two tph to and from Bishops Stortford via Meridian Water
  • Two tph to and from Norwich via Stansted
  • Four tph to and from Chingford via the Hall Farm Curve.
  • Two tph to and from Enfield Town via South Tottenham and Seven Sisters
  • Two tph to and from Cheshunt via South Tottenham and Seven Sisters

That is an easy-to-handle fourteen tph.

This map from carto.metro.free.fr, shows the lines connecting the North London Line and the High Meads Loop to platforms 1m 2, 11 and 12 at Stratford station.

Given that freight trains pass through the area to get between the North London Line and the Great Eastern Main Line, there may need to be some track reorganisation to make full use of the High Meads Loop.

Digital signalling would also help, as it would all over the London Overground network.

I think it would not be unreasonable to expect that in some point in the future twenty tph could be running around the High Meads Loop.

A new rail terminus for London would have been created with the ability to handle more trains than either Cannon Street, Fenchurch Street or Marylebone. stations.

Could we see all West Anglia Main Line services terminate in the High Meads Loop?

Probably not, as the platform wouldn’t be able to cope with all the passengers.

Crossrail 2

If Crossrail 2 is ever built, it will terminate at Broxbourne on the West Anglia Main Line.

It will need four-tracking of the West Anglia Main Line between  Tottenham Hale and Broxbourne stations, which will create massive disruption for passengers and residents.

Conclusion

There is a lot of development, that is possible on the West Anglia Main Line to make it into a world-class commuter route and a main line route with good services to Stansted Airport, Cambridge and Norwich.

Cambridge is a big growth point in the UK economy and dveloping the West Anglia Main Line will only improve the economy of the area.

Could A Platform Or Platforms Be Added To The High Meads Loop To Improve Connectivity At Stratford?

This Google Map shows Stratford International station..

The main station is obvious, but note the Stratford International DLR station to the North on the other side of Interbational Way.

  • From the DLR station the tracks curve Southwards and cross the High Speed tracks towards St. Pancras.
  • Alongside these tracks is the double-track High Meads Loop.
  • On the Northern side of the DLR station, the loop enters a tunnel to connect the tracks to Lea Bridge and Tottenham Hale stations.
  • At the Southern end, the loop connects to the tracks that go through platforms 11 and 12 of the domestic Stratford station, before joining with the other side of the High Meads Loop at Temple Meads East Junction to go North.
  • Platform 11 would handle trains going clockwise round the loop and Platform 12 those going anti-clockwise.

This map from carto.metro.free.fr shows the track layout in detail.

The loop has been used in the past to turn Stansted Expresses that ran to Stratford, where they called in Platform 12. The signs are still there, as this picture, which was taken at the Eastern end of the Overground plstforms 1 and 2, shows.

The capacity of the loop must be quite large.

  • A similar single-track loop under Liverpool handles as many as fourteen trains per hour (tph).
  • The double-track loop could probably handle upwards of sixteen tph.

The following is also planned, is happening or could happen.

  • Crossrail should open in 2019 giving a direct connection between Stratford and Heathrow via Paddington, the West End and Liverpool Street.
  • Four tph will run between Stratford and Meridian Water stations.
  • A Stansted Express service between Stansted and Stratford could be reintroduced.
  • Liverpool Street is getting increasingly crowded.
  • London Overground might  run services between Stratford and the Lea Valley.

Utilising the capacity of the existing High Meads Loop would probably be an easier option, than expanding Liverpool Street.

I arrived at Stratford International DLR station today and after using the Western entrance, I took these pictures.

The High Meads Loop is not that far from the DLR station and there would appear to be scope to create at least one platform.

This Google Map shows the Western end of the DLR station and the High Meads Loop.

I think there is scope in the area to create a link between the three stations at the Western end of the DLR station, which is the building with the blue roof.

It could also be a better walking route to the Internation station, as you won’t have to fight your way through Eastfields.

Conclusion

I think it will be tricky, but a better interchange will be created.

How Will Greater Anglia/London Overground Use The Third Track On The West Anglia Main Line?

This morning as I often do, I took the 11:00 train between Stratford and Enfield Lock stations.

I like to have a look at progress on STAR, which involves the following.

  • A five and a half kilometre third track to the East of the current two tracks of the West Anglia Main Line between Lea Bridge and Angel Road stations.
  • A third platform and station improvements at Tottenham Hale station.
  • A third platform, removal of a level crossing and complete rebuilding of Northumberland Park station.
  • Building of a completely new three-platform station at Meridian Water to replace the current inadequate Angel Road station.

This Google Map shows the location of Meridian Water station with respect to Tesco Extra and IKEA in Glover Drive.

You can just see the concrete foundations of the station and its platforms alongside the West Anglia Main Line to the West of the Tesco Extra.

In Meridian Water Station – 14th June 2018, I show pictures of the station just over two months ago.

There has been steady and worthwhile progess since.

  • Meridian Water station now has platforms under construction.
  • Northumberland Park station looks like it could be ready before Spurs’ new stadium.
  • The lift towers for the footbridge at Tottenham Hale station are being erected.
  • I estimate about seventy percent of the third track has been laid.
  • All the electrification gantries seem to have been erected and there are even some overhead wires.

The target for finishing the works is said to be May 2019 and I suspect that is achievable.

Use Of The Third Track

It certainly looks like the third track will be ready, so how will it be used?

The Northern End

At the Northern end, the third track appears to finish in a bay platform at Meridian Water station.

Once Angel Road station is closed and reduced to rubble, there would be plenty of space to add a junction, so that trains going South towards Stratford, could use the third track.

This would surely ease operation of the West Anglia Main Line.

Meridian Water Station

Meridian Water station appears to be being built as a three-platform station with provision for a fourth.

From various drawings and notes on the Internet it looks like there will be two platforms on the West Anglia Main Line and a separate bay or through platform to the East.

This map from carto.metro.free.fr shows the relationship of Angel oad and Meridian Water station.

The dotted line on the map is the third track.

I took these pictures from a slow train through the station.

It looks very much like a through platform is being created.

I feel that access to this platform will be in two ways.

  • From the North via a junction with the Southbound track of the West Anglia Main Line. This junction could be to the North the current Angel Road station.
  • From the South using the new third track.

This would mean that no trains will have to cross the West Anglia Main Line using a flat junction.

I don’t believe that trains can run bi-directionally on the third track, as there is not enough time in an hour for four trains to shuttle between Lea Bridge and Meridian Water.

So that means all services calling at Meridian Water will go further up the Lea Valley to turn back.

Using The Third Platform At Tottenham Hale Station

I think it is likely that the current two platforms will be used as follows.

  • Platform 2 – Northbound trains
  • Platform 1 – Southbound trains to Liverpool Street

It would be logical that the new third platform would handle Southbound trains to Stratford.

As Platform 1 and the new platform share an island, passengers will have a step-free cross-platform  interchange, if they need to go to the alternative destination.

The following journey times should be noted.

  • Tottenham Hale to Stratford currently takes 14 minutes
  • Tottenham Hale to Liverpool Street currently takes between 14 and 17 minutes
  • Liverpool Street to Stratford will take eight minutes on Crossrail

I suspect a lot of passengers will change to a direct train.

It could also mean that an ideal service would see the same frequency of trains at both platforms.

The Southern End

At the Southern end, the third track joins the West Anglia Main Line going towards Stratford, but there is also a crossover to allow trains coming from Stratford to use the third track.

Is The Third Track Going To Be Bi-Directional?

Loops like this third track are often signalled to be bi-directional, to ease operation. But as I said earlier, I think the third track is too long to operate in that way all the time with passenger services.

What Will Be The Operating Speed Of The Third Track?

I have watched the third track being constructed and it is totally new.

  • All bridges have been replaced with new structures.
  • The track is fully electrified.
  • There appear to be no junctions, except at the two ends.

Everything certainly looks professional to my untrained eye.

The operating speed will probably be determined by the time set for the driver to take the train between stations on the line.

But the track has surely been designed to minimise the time between Meridian Water and Stratford.

Could The Third Track Be Extended Northwards?

The length of the third track is 5.5 km.

Could the third track be extended to the North?

If Crossrail 2 is built, there will be a need to make the route four tracks.

  • Two fast tracks for the expresses between London, Stansted and Cambridge.
  • Two slow tracks for Crossrail 2 as far as the terninus at Broxbourne.

These are my observations

  • Looking from both a train and on Google Map, it appears that it will be a tight fit to squeeze in two tracks.
  • There is the serious problems of the two level crossings at Brimsdown and Enfield Lock stations.
  • Waltham Cross station seems very tight too.

But I do think, that with a clever redesign at the three troublesome stations, that a third track, but not necessarily a fourth can be squeezed in  as far as North as Broxbourne, which would be another 11.2 miles.

Although in places, like these pictures taken just South of Tottenham Hale station show, there may be plenty of space for two tracks.

I suspect that to put in the fourth track will mean that the bridge at Ferry Lane will need to be rebuilt.

But it does appear that in building the third track, the builders are making sue there is space for a fourth track to be added in a few years.

Currently, How Many Calls Are There At Each Station?

These figures are calculated from the current timetable.

Lea Bridge

  • Two trains per hour (tph) – Stratford to Bishop’s Stortford

Two tph stop in both platforms.

Tottenham Hale

  • Two tph – Liverpool Street to Hertford East
  • One tph – Liverpool Street to Cambridge
  • One tph – Liverpool Street to Cambridge North
  • Four tph – Liverpool Street to Stansted Airport
  • Two tph – Stratford to Bishop’s Stortford

Two tph would terminate at the station.

In addition, two tph pass through both platforms without stopping.

A Summary Of Current Services

This is summary of stops at the selected stations.

  • Lea Bridge – 2 tph
  • Tottenham Hale – 10 tph
  • Northumberland Park – 2 tph
  • Meridian Water – 2 tph
  • Ponders End – 2 tph
  • Brimsdown – 2 tph
  • Enfield Lock – 3 tph
  • Waltham Cross – 4 tph
  • Cheshunt – 6 tph
  • Broxbourne – 6 tph
  • Harlow Town – 6 tph
  • Bishop’s Stortford – 6 tph

Note.

  1. To say the least service is a bit patchy, with some stations getting a much better service than others.
  2. London Overround, Merseyrail and others feel that a service of four tph is highly desirable and attracts passengers.

The service definitely needs improvement.

STAR Services

It is certainly intended that four tph, will be run between Stratford and Meridian Water stations calling at Lea Bridge, Tottenham Hale and Northumberland Park stations.

Current Services

Currently, this service is provided at a frequency of two tph by Greater Anglia, who extend the service to Bishop’s Strortford station.

There are various ways that this could be increased to four tph

Possible Northern Terminals

As I said earlier to avoid train-slowing flat junctions, STAR services must terminate North of Meridian Water station.

I think there are these possibilities.

  • Bishop’s Stortford, which currently handles two tph in the bay platform 3.
  • Broxbourne which is a large station with 8 platforms and has been earmarked as the terminal for Crossrail 2.
  • Hertford East has platform space, but there may not be the capacity for the trains on the Hertford East Branch.

Passenger numbers will drive the choice, but I suspect all three terminals have their merits.

In the following sub-sections I’ll look at each terminus.

Two Extra Trains To Bishop’s Stortford

I will assume these services will call at the same stations as the current two trains.

This is summary of stops at the selected stations.

  • Lea Bridge – 4 tph
  • Tottenham Hale – 12 tph
  • Northumberland Park – 4 tph
  • Meridian Water – 4 tph
  • Ponders End – 2 tph
  • Brimsdown – 2 tph
  • Enfield Lock – 4 tph
  • Waltham Cross – 8 tph
  • Cheshunt – 8 tph
  • Broxbourne – 8 tph
  • Harlow Town – 8 tph
  • Bishop’s Stortford – 8 tph

Note.

  1. Enfield Lock now has the preferred four tph.
  2. Ponders End and Brimsdown probably need more services.
  3. Are there too many services at Harlow Town and Bishop’s Stortford?

But generally, it is a better distribution than now!

Two Extra Trains To Broxbourne Or Hertford East

I will assume these services will call at the same stations as the current two trains, that run between Stratford and Bishop’s Stortford.

This is summary of stops at the selected stations, which will be the same for both destinations.

  • Lea Bridge – 4 tph
  • Tottenham Hale – 12 tph
  • Northumberland Park – 4 tph
  • Meridian Water – 4 tph
  • Ponders End – 2 tph
  • Brimsdown – 2 tph
  • Enfield Lock – 4 tph
  • Waltham Cross – 8 tph
  • Cheshunt – 8 tph
  • Broxbourne – 8 tph

Note.

  1. Enfield Lock now has the preferred four tph.
  2. Ponders End and Brimsdown probably need more services.
  3. There will be no increase in frequencies North of Broxbourne.

Operational needs and passenger numbers will decide if these are better destinations.

Use Of The High Meads Loop At Stratford

The High Meads loop under the Eastfield Shopping Centre was designed to turn trains.

This map from carto.metro.free.fr shows the loop.

On the map it is the horeshoe-shaped double track shown in black.

  • , It goes through Platforms 11 and 12 in Stratford station.
  • Currently, Platform 11 is used exclusively as a terminal for the two tph between Stratford and Bishop’s Stortford.
  • Currently, Platform 12 is not used and the track is used to take trains to and from the Orient Way sidings
  • Both ends of the loop join together just to the South of the Orient Way sidings and Lea Bridge station.
  • In the past it has been used to turn Stansted Expresses, which used Platform 12 according to the signs still in place.
  • I believe it would be possible to build a platform on the loop to serve Stratford International station and the Northern part of the Olympic Park.

In my view it is wasted fully-working infrastructure.

The Wirral Line Loop Under Liverpool

The most important rail loop in the UK is the loop of the Wirral Line under Central Liverpool.

  • The loop is single-track with three single-platform stations
  • This loop handles fourteen tph.
  • The loop is built for full-size trains.
  • Trains take eight minutes to go round the loop from Liverpool James Street station and fourteen minutes from Birkenhead Hamilton Square station on the other side of the Mersey.

It was built in the early 1970s and I’m sure the designers of the High Meads Loop were influenced strongly by the track layout in Liverpool.

The Wirral Line Loop showcases the major examples of this type of track layout.

  • The driver just keeps driving and doesn’t have to change ends.
  • A single terminal platform can handle a maximum of perhaps 4-6 tph, whereas a single platform on a loop can handle at least 14 tph.
  • Stations can be provided at several places on the loop, where they are needed.

A loop is a very fast and simple way to turn trains.

Time Saving At Stratford Using The High Meads Loop

The 06:34 from Bishop’s Stortford stops at Tottenham Hale at 07:29, Lea Bridge at 07:33 and Stratford at 07:43.

The train then forms the 08:04 from Stratford, which stops at Lea Bridge at 08:10, Tottenham Hale at 08:18 and terminates at Bishop’s Stortford at 09:02.

So the train has taken thirty-seven minutes between the two calls at Lea Bridge station on a modern double track railway.

If the train loaded and unloaded passengers at Platform 11 at Stratford, I suspect that this time could be reduced to under twenty minutes, if the train continued round the High Meads Loop.

Even if there was an extra station on the loop to serve Stratford International station and the Northern part of the Olympic Park, I suspect that a saving on twenty minutes could be made.

Greater Anglia would be a big beneficiary. Currently the train leaves Bishop’s Stortford at 06:34 and arrives back at 09:02, which means a total trip time of 148 minutes for an out-and-back journey with ten intermediate stops both ways.

With a bit of time saving and the new Class 720 trains, I suspect that with the turnround time at Bishop’s Stortford added in, that a train could do the full trip within two and a half hours.

This would mean that ten trains would be needed for a four tph service between Stratford and Bishop’s Stortford.

Take off the twenty minutes saved by the High Meads Loop and the minutes saved by the new trains and I believe that well-driven trains could do the full trip in two hours

This would mean that eight trains would be needed for a four tph service between Stratford and Bishop’s Stortford.

Stansted Airport To Stratford

How much time would be saved if Stansted Airport trains went to Stratford and used the High Meads Loop?

The fastest trains take forty-seven minutes between Liverpool Street and Stansted, with about fourteen minutes needed for the short stretch between Liverpool Street and Tottenham Hale.

Using the High Meads Loop at Stratford would probably mean a similar journey time, as from Liverpool Street, but there would be other advantages, disadvantages and score draws.

  • Both platforms used by Stansted Expresses would be step-free.
  • Train tracks to Stratford are probably less likely to delay.
  • Walking routes at Stratford might be shorter.
  • Both Liverpool Street and Stratford will be served by Crossrail.
  • Stratford could have links to Highspeed services to Kent.

Greater Anglia would be a big winner, as they would have a better train utilisation.

What Length Of Trains Could Use The High Meads Loop?

The only restriction will be the length of platforms at Stratford, Lea Bridge and Tottenham Hale.

Without getting my tape measure out, I suspect they are all capable of taking a twelve-car Class 317 train, which is around 240 metres long.

Ten-car versions of Greater Anglia’s new Class 720 trains are 243 metres long.

I would be very surprised if the platforms couldn’t accept these long trains.

What Would Be The Ultimate Capacity Of The High Meads Loop?

Consider.

  • The Wirral Line Loop under Liverpool handles fourteen tph.
  • More complicated tunnels under London like Crossrail, the East London Line and Thameslink are planned to handle 24 tph.
  • Modern digital signalling will be applied in the next couple of decades to the West Anglia Main Line.

Consider.

  • The Southbound third track and the route to Stratford from Lea Bridge can probably easily handle fifteen tph or a train every four minutes.
  • Platform 11 at Stratford with perhaps some escalators, could probably handle fifteen or even twenty tph, as do stations like Canada Water and several stations on Thameslink and the Wirral Line.
  • Northwards from Stratford, there is probably a total limit of twelve tph along the Lea Valley, that could be increased by removing level crossing and modern signalling.

I suspect that the ultimate capacity is way in excess of the number of services that need to be run from Stratford up the West Anglia Main Line.

Using The High Meads Loop To Take Pressure From Liverpool Street

Liverpool Street is crowded.

  • Some platforms can’t accept full length trains.
  • West Anglia services crawk between Liverpool Street and Tottenham Hale at a speed of not much more than 40 mph at times.
  • The two operators; London Overground and Greater Anglia want to add additional services to the station.
  • c2c also want to serve the station, as they have capacity problems at Fenchurch Street.

However, future developments will make Stratford a viable alternative to Liverpool Street.

  • Crossrail will provide a high-capacity service linking both stations to the Canary Wharf, Heathrow and the West End.
  • Better access to the Central Line will happen.
  • Stratford has access to the important Jubilee Line.
  • Stratford will be able to take advantage of Docklands Light Railway developments.
  • Tottenham Hale station will have better interchange to the Victoria Line.

So why not move some services from the West Anglia Main Line to the High Meads Loop?

What Services Could Be Transferred From Liverpool Street To The High Meads Loop?

At present, all stopping trains between London and Bishop’s Stortford, start from Stratford and I can see this continuing after the third track opens.

I could also see extra services on this route to deliver the promised four tph to Meridian Water and Nothumberland Park.

Four tph can probably use Platform 11 st Stratford, but looking at the smooth unhurried operation of the Wirral Line Loop at Liverpool, I suspect that the High Meads Loop will be used.

Looking at all the other services between Liverpool Street and Tottenham Hale, only the two tph between Liverpool Street and Hertford East, stop at another station, which is South of Tottenham Hale.

So it would probably not be sensible to transfer theseHertford East services to the High Meads Loop, but it might be a good idea to add two tph all day between Stratford and Hertford East, to create a four tph service to Hertford East with two tph from both Southern terminals.

Some services between Liverpool Street and Cambridge and between Liverpool Street and Stansted might be augmented with more services or moving the services to the High Meads Loop at Stratford.

I would suggest that about half the services went to Liverpool Street and terminated as they do now and the rest used the High Meads Loop.

This would mean that those, who’d caught the wrong train or changed their destination, could just change at Tottenham Hale by walking across the island platform.

I was on a train going South to Liverpool Street recently, when I changed my mind and transferred to a Stratford train. As I inew a Stratford train was close behind, I only had to wait a few minutes.

Note that, if there are six trains on both branches, then the maximum wait would be ten minutes.

Examining A Possible Timetable

This is definitely my speculation, but I am trying to show what is possible!

I also very much believe that Network Rail, Greater Anglia and London Overground will come up with something much better.

A Few Rules

I am using these rules to guide me in my thinking.

  1. All trains going to Stratford use the High Meads Loop and Platform 11 at Stratford.
  2. No station gets an inferior service to that it gets at the present time.
  3. All Southbound trains for Stratford use the new third track between Meridian Water and Lea Bridge Junction.

I think that this could be a good mix of services.

  • One tph Liverpool Street to Cambridge
  • One tph Liverpool Street to Cambridge North
  • Two tph Liverpool Street to Hertford East
  • Four tph Liverpool Street to Stansted
  • Four tph Stratford to Bishop’s Stortford
  • Two tph Stratford to Hertford East
  • Two tph Stratford to Stansted

Note.

  1. Greater Anglia have said they will run a Stratford to Stansted service from 2019.
  2. The two extra Stratford to Bishop’s Stortford and Hertford East services will have similar calling patterns to the existing services.
  3. Eight tph goes to and from both Liverpool Street and Stratford.
  4. Currently, eight tph run between Tottenham Hale and Liverpool Street.
  5. Based on the my observations of the relaxed operation of the Wirral Line Loop under Liverpool, I feel the capacity of the High Meads Loop could be as high as sixteen tph.
  6. Calling patterns will be adjusted to improve frequencies at Ponders End and Brimsdown stations
  7. The only other passenger trains on the route are two tph between Stansted Airport and Cambridge.

The number of trains running on each section of track would be as follows.

  • Eight tph – Liverpool Street to Tottenham Hale
  • Eight tph – Stratford to Tottenham Hale – Southbound trains use the third track where is has been added.
  • Sixteen tph – Tottenham Hale to Broxbourne – Southbound trains use the third track where is has been added.
  • Twelve tph – Broxbourne to Bishop’s Stortford
  • Eight tph – Bishop’s Stortford to Stansted Airport
  • Six tph – Stansted Airport to Cambridge

I’m not sure if this would be achievable, but there are several double-track main lines in the country, that handle at least sixteen tph.

Extra Services On The Lea Valley Routes Of The London Overground

The London Overground services from Liverpool Street to Cheshunt and Enfield Town have the following characteristics.

  • A frequency of two tph.
  • Extra peak hour services.
  • Both services pass through Hackney Downs and Seven Sisters stations.

London Overgriound probably want to add two extra tph to both routes to increase the frequency to four tph. Unfortunately, the crowded lines South of Seven Sisters and a full Liverpool Street station, probably make this difficult.

Look at this map from carto.metro.free.fr, which shows the lines South of Tottenham Hale and Seven Sisters stations.

South Tottenham station is on the Gospel Oak to Barking Line, with the following connections.

  • At the Western end of the station, the Seven Sisters Chord connects the station to the Lea Valley Line to Cheshunt and Enfield Town.
  • At the Eastern end of the Tottenham South Curve connects the station to the line to the High Meads Loop at Stratford.

Would it be possible to run the extra two tph from both Cheshunt and Enfield Town to the High Meads Loop?

If it is possible, then the following frequencies will be achieved.

  • Four tph between Cheshunt and Edmonton Green
  • Four tph between Enfield Town and Edmonton Green
  • Eight tph between Edmonton Green and Seven Sisters.
  • Four tph between Seven Sisters and Stratford.

But more importantly, it will create more routes for East London’s Duckers-and-Divers to challenge the clock.

  • Large parts of Enfield and Haringey now get a direct connection to Stratford.
  • The new White Hart Lane station will have a direct connection to Stratford.
  • Stratford to stations on the Gospel Oak to Barking Line is now just a step-free change at South Tottenham station.

I also wonder how many new sites for housing will become viable because of all the new transport links.

Future Developments

There are several developments planned or proposed, that will affect traffic on the West Anglia Main Line.

Track Improvements

The mainly two-track West Anglia Main Line has a maximum operating speed of 100 mph, but travelling the line over the last few days, at times we were only travelling at about 50 mph for long periods.

So I suspect that the average operating speed could be increased.

There are also several level crossings, including those at Brimsdown, Enfield Lock and Cheshunt on the busiest Southern section of the route..

Digital Signalling

Modern digital signalling on the West Anglia Main Line must allow more trains to be squeezed into the timetable.

New Trains

The current trains that work the West Anglia Main Line are Class 379 and Class 317 trains.

Both trains are 100 mph trains although the Class 317 trains are now nearly forty years old.

They are being replaced with Class 720 and Class 745 trains, which although they are also 100 mph trains, may offer advantages, because they are newer designs.

  • Better acceleration and smoother regenerative braking.
  • Easier passenger entry and exit.
  • Shorter dwell times at stations.
  • Better passenger comfort and facilities.

But crucially, they will be able to take advantage of the modern digital signalling.

I think it is very likely that the new trains will speed up services on the West Anglia Main Line.

I also think that the combination of digital signalling and new trains, that are capable of using it, will allow higher frequencies of trains to be run on the West Anglia Main Line.

A Possible Pattern Of West Anglia Line Services

Could we see the following in the future?

  • London Overground services on the Lea Valley Lines use Liverpool Street, as they do now.
  • Greater Anglia services on the West Anglia Main Line to Bishop’s Stortford, Cambridge, Hertford East and Stansted Airport are split between Liverpool Street and Stratford.
  • Stratford services use the High Meads Loop and stop at either Platform 11 or 12 at Stratford.

It would certainly increase terminal capacity at the Southern end of the West Anglia Main Line and free up platform space in Liverpool Street.2 ru

.Conclusion

I wouldn’t be surprised to see the following.

  • Twenty tph up and down the West Anglia Main Line.
  • Direct services up the West Anglia Main Line to Norwich via Cambridge using bi-mode Class 755 trains.
  • Extra services between Stratford and Cambridge, Hertford East and Stansted.
  • Services are adjusted so that each station South of Broxbourne gets four tph or more.

Note that I haven’t mentioned adding a fourth track.

I believe that my calculations show it might not be needed to achieve the required intensive service on the West Anglia Main Line.

Musings On The West Anglia Main Line

The West Anglia Main Line is the main railway between Liverpool Street station in the City of London and the Scientific Powerhouse of Cambridge via Stansred Airport.

This post started off as The Mother Of All Level Crossing Jams, when I got caught in a jam caused by the level crossing at Enfield Lock station.

It has since grown into a long post of the inadequacies of this important main line.

The Mother Of All Level Crossing Jams

These are pictures I took at Enfield Lock station in mid-morning.

I had arrived at the station at 11:04 and my train had departed on its way at 11:08.

I was in no hurry taking the pictures and I left at 11:22 after eight trains had gone through, without the gates being raised.

In two of the pictures, you can see a discarded broken gate. Was it caused by an irate motorist?

After I got back to the station, the barriers were still going up and down like a whore’s drawers and talking to a fellow passenger, she said it happens all the time.

Improving The West Anglia Main Line

Consider the following, which could effect what happens in the future.

  • Stansted Airport, Greater Anglia, Transport for London, the London Borough of Enfield, Cambridge City Council and the local MPs, all want the line to be four-tracked so that services to Cambridge and Stansted Airport can have their own dedicated fast lines.
  • ,Greater Anglia have ordered lots of new trains and I suspect they want to run much-needed extra services into both Stratford and Liverpool Street stations.
  • Enfield Lock could be a Crossrail 2 station in ten years or so.
  • Crossrail 2 would want to run up to twelve trains per hour (tph).

It is a certainly a case of squeezing a couple of gallons into a pint pot.

Enfield Lock And Brimsdown

To make matters worse there is another equally congested level crossing at the next station to the South; Brimsdown.

This Google Map shows the area.

Note.

  1. Enfield Lock station is in the North West corner of the map, with Brimsdown in the South West corner.
  2. Mollinson Avenue, which tracks along the railway to its East, is nearly all dual carriageway.
  3. These is a lot of industrial premises in the area.
  4. There are a lot of distribution depots that need road access for heavy trucks.
  5. It is going to use all the ingenuity that Network Rail can muster to squeeze two extra tracks between those two stations.

If ever there was an area that needs an increased rail service it is this stretch of the West Anglia Main Line between Tottenham Hale and Cheshunt stations.

Improving The Lea Valley Lines

I suspect that British Rail foresaw the problem in the 1950s, as by 1960, they had electrified all the Lea Valley Lines including the goods-only Southbury Loop, which is now part of the London Overground, who run two tph on the route.

Both London Overground and Greater Anglia are getting new Aventra trains, which should increase the capacity and speed up services on both routes.

However, this could create a problem, in that they are such good trains, they may persuade more commuters to leave their cars at home and take the trains.

More Frequent Services

London Overground like to run four tph on their various routes.

At present, their Lea Valley services are as follows.

  • 4 tph from Liverpool Street to Chingford.
  • 2 tph from Liverpool Street to Enfield Town, with more services in the Peak and when Spurs are playing at home.
  • 2 tph from Liverpool Street to Cheshunt.

I suspect that they would like to run four tph all day and that after Crossrail opens and releases some platforms at Liverpool Street, this might happen.

However in Increased Frequencies On The East London Line, I publish a table, which says that from 2019, Enfield Town will get four tph.

Greater Anglia must be looking to improve services on the West Anglia Main Line, so that all stations South of Broxbourne get four tph, with perhaps two tph to each of  Liverpool Street and Stratford.

And then there’s STAR, which is a new service between Stratford and Angel Road stations. This article on IanVisits, which is entitled One of London’s quietest train stations set for major upgrade, gives a good explanation of this service, which will provide four tph between Stratford and a rebuilt Angel Road station, which will be renamed Meridian Water.

More Terminal Capacity In London

Adding these services together, I feel that  more capacity is needed at the London terminals of Liverpool Street and Stratford.

There are two short term solutions and one long term one.

Create More Capacity At Liverpool Street

This is the simplest short-term solution.

In the Wikipedia entry for Liverpool Street station, this is said.

Once Crossrail opens, platform 18 at the main Liverpool Street station will be decommissioned to allow platforms 16 and 17 to be extended, enabling them to accommodate longer trains.

I would assume this platform-lengthening is to accommodate the full-length Class 345 trains, that will run the Peak Hour service between Liverpool Street and Gidea Park stations.

I suppose too, having two platforms in Liverpool Street, that are capable of handling Crossrail trains must also be useful in special or exceptional circumstances.

Platform 18 is a curiosity, in that it is used by c2c as a diversion platform, when Fenchurch Street station is closed because of engineering works.

So after the work on platforms 16 and 17 is complete, will it be recommissioned?

That leaves fifteen platforms for Greater Anglia and London Overground to argue over.

If you compare the way Liverpool Street is organised compared to some more modern stations, I suspect that more modern trains can be handled without any expensive modifications to the existing station.

Modern practice means that a single platform can easily handle four tph, so as destinations like Norwich and Southend will only have three tph, could it mean that these destinations can be served by a single platform?

It would certainly make it easy for me, if I knew the fast Ipswich trains always left from platform 9.

I suspect that as London Overground has only three destinations; Cheshunt, Chingford and Enfield Town, whiich have a maximum frequency of four tph, that they could easily manage with four platforms; one for each destination and a spare.

This would give Greater Anglia eleven platforms.

Note this about Greater Anglia’s new trains.

  • The Class 745 trains will be of a fixed formation of twelve cars.
  • Will the three-car and four-car Class 755 trains have the ability to join and split automatically?
  • Will the five-car Class 720 trains have the ability to join and split automatically?

Having seen how Class 395 trains and others can do this in under a couple of minutes and the flexibility of destinations it gives, I will be very surprised if Greater Anglia haven’t specified this capability.

  • As an example, two four-car Class 755 trains could start at Lowestoft and Bury St. Edmunds respectively and then join at Ipswich, before proceeding to London as an eight-car train.
  • Would it be sensible that all trains go into Liverpool Street at maximum length?
  • Trains might split and join at Ipswich, Colchester and perhaps Chelmsford. All that is needed is a long platform.

Perhaps Greater Anglia’s platforms at Liverpool Street could be allocated something like this.

For Flirts (Class 745 and Class 755)

  • Norwich
  • Ipswich/Lowestoft
  • Stansted Airport
  • Cambridge

For Aventras (Class 720)

  • Bishops Stordford/Broxbourne/Hertford East
  • Colchester/Harwich
  • Clacton/Walton
  • Chelmsford/Braintree
  • Southend

On this rough assessment, it would appear that at least for a few years Liverpool Street station could cope.

Developing Stratford As A Second Terminal

Consider these facts about the railway hub at Stratford.

  • Stratford has not been fully developed as a terminal for the West Anglia routes and only handles two tph to and from Bishops Stortford.
  • Stratford has two platforms 11 and 12, that were built to serve the West Anglia routes; the West Anglia Main Line and the Lea Valley Lines.
  • Platforms 11 and 12 are on the High Meads Loop, which would reverse the trains on West Anglia routes.
  • Stratford is well connected to Crossrail, Central and Jubilee Lines of the Underground, the DLR, the Overground , Highspeed services to Kent and Greater Anglia services on the Great Eastern Main Line.
  • Stratford has better connections than Liverpool Street to London Bridge and Waterloo
  • Stratford could have excellent connections to Highspeed services to Kent and Continental services at Ashford International.
  • Stratford will be only a few minutes from Liverpool Street on Crossrail.

Stratford is also a destination in its own right, with the Queen Elizabeth Olympic Park and the massive shopping complex.

This map from carto.metro.free.fr shows the complex at Stratford.

It is very much capable of development.

  • Better connections could be made between Stratford International and the main station.
  • The subways in the complex could be improved.
  • The Hall Farm Curve could be reinstated to give direct connections between Stratford and Walthamstow/Chingford.

I would not be surprised if Greater Anglia increased their services to and from Stratford.

I could also envisage a timetable, where trains alternate between the two terminals., as every passenger will have their favoured terninal.

Crossrail 2

Crossrail 2 is the long-term solution.

Upwards of ten tph will run between Broxbourne and Tottenham Hale, before entering the tunnel to Central and South West London.

It will obviously handle all the local services South of Broxbourne, with just the services from the North continuing to Liverpool Street and Stratford.

Following Abbey Wood, Reading and Shenfield stations on Crossrail, I think that we would see Broxbourne station developed as a simple interchange between longer distance services and Crossrail 2.

Both services would have their own tracks to London.

Conclusion

The West Anglia Main Line urgently needs improvement and this improvement can be broken down into a series of smaller projects, the first three of which have already started and could be completed by 2020.

  1. Creation of STAR – The Stratford-Angel Road Metro – Already started.
  2. Building of new Meridian Water station to replace Angel Road station – Already started.
  3. Rebuilding of Tottenham Hale station – Already started.
  4. Post-Crossrail Improvements at Liverpool Street and Stratford stations.
  5. Removal of level crossings at Brimsdown, Enfield Lock and Waltham Cross
  6. Four-tracking between Tottenham Hale and Broxbourne.
  7. Step-Free Stations
  8. Reinstatement of the Hall Farm Curve.

These projects will also get the main line Crossrail 2-ready.

This process has already started with the creation of STAR, which will create a third track as far as Angel Road station. In the article on IanVisits, this is said.

Along the tracks nearby there are already hi-vis wearing Network Rail contractors clearing the land to prepare it for the Stratford to Angel Road (STAR) rail upgrade project which will see a third railway track added. Passive provision for a fourth track will be included for Crossrail 2.

This work has already closed the level crossing at Nothumberland Park station.

In Innovation In Railway Projects, I describe how Network Rail are aiming to create a pipeline of smaller projects.

I feel that some parts of the updating of the West Anglia Main Line can be done in this way.

17 Tube Stations That Face Chronic Overcrowding If Crossrail 2 Is Stopped

The title of this post is the same as that of an article in today’s Standard.

This is the first two paragraphs.

Hundreds of thousands more Londoners will suffer chronic overcrowding on the Tube if Crossrail 2 does not go ahead, it was claimed today.

Transport for London released a list of 17 Underground stations that could buckle under the strain of too many commuters within a few years.

It then lists the stations.

  • Euston
  • King’s Cross St. Pancras
  • Liverpool Street
  • London Bridge
  • Victoria
  • Waterloo
  • Finsbury Park
  • Stockwell
  • Stratford
  • Oxford Circus
  • Highbury & Islington
  • Clapham Common
  • Clapham North
  • Clapham South
  • Holborn
  • Warren Street
  • Leicester Square

It then quotes Caroline Pidgeon, who obtained the list, as follows.

Overcrowding on the Underground is already a daily battle, with many passengers facing regular delays to simply get through barriers at stations.

Unless Crossrail 2 is built these delays will increasingly build up until drastic measures are necessary at 17 key Tube stations, not to mention Clapham Junction railway station.

“Planning ahead for Crossrail 2 is not an optional extra for London’s transport network but of vital importance to keep London moving.

She has certainly highlighted a serious problem.

Call For Crossrail 2

Two years ago to the day, I wrote a post called Call For Crossrail 2 in response to a letter in The Times, from a wide cross section of business leaders calling for a start to be made on the line.

In the post, I talked about improving various stations, just by building Crossrail 2, so in the following notes on the list of crowded stations, I will refer to this post several times in the following.

Euston

Euston tube station is a particular problem in that in the next decade or so, the following will or could happen.

Hopefully, the rebuilding for whichever comes first of  HS2 or Crossrail 2, will make provision for even the most fanciful of expansions.

One Transport for London engineer told me that one of the main reasons for building HS2 and terminating it at Euston, is to be able to sort out the dreadful Euston tube station.

Kings Cross St. Pancras

Kings Cross St. Pancras tube station had a pretty good makeover around the time of the 2012 London Olympics, but it does suffer congestion and travellers have to walk long distances.

The Wikipedia entry for Kings Cross St. Pancras tube station has a section for Crossrail 2. This is said.

Since 1991, a route for a potential Crossrail 2 has been safeguarded, including a connection at King’s Cross St Pancras and Euston, forming the station Euston King’s Cross St Pancras. The proposed scheme would offer a second rail link between King’s Cross and Victoria in addition to the Victoria line. The locations for any new stations on the route will depend on the loading gauge of the final scheme. In the 2007 safeguarded route, the next stations would be Tottenham Court Road and Angel.

There is also a proposal to reopen the closed York Road tube station. In the Wikipedia entry for York Road station under Proposed Reopening, this is said.

One of London’s largest redevelopment projects, King’s Cross Central, began construction in 2008 across the road from the station. Islington council and Transport for London commissioned a study in 2005 to consider the possible reopening of the station. At the same time, however, it was recognised that other transport priorities reduced the likelihood of such a project moving forward in the near future. The site would need extensive overhauls to bring the station up to modern day standards, at a cost estimated at £21 million in 2005. Local political groups have been keen to see the station reopened in order to reduce passenger congestion at King’s Cross St. Pancras and to encourage development in the surrounding community. The Islington Liberal Democrats advocated the reopening of the station in their 2006 local election manifesto, and at least one candidate for the Islington Conservative Party similarly campaigned for the station to be reopened. However, to date, the reopening proposal has not been taken forward.

I wonder if York Road tube station will ever be reopened.

Liverpool Street

The Liverpool Street station complex will be even bigger and busier after Crossrail opens.

The main difference will be that the current Shenfield Metro will now disappear into the ground at Stratford and go under Central London to Heathrow and Reading.

Crossrail 2 will effectively channel the Lea Valley services, that current go into Liverpool Street station under London to emerge in the Wimbledon area.

Effectively, Crossrail and Crossrail 2 major effect on Liverpool Street station are to free up capacity in both tracks and platforms, thuis allowing more longer distance services to use the station.

London Bridge

London Bridge station is being rebuilt and expanded, but little seems to be planned for London Bridge tube station to cope with more passengers.

In Call For Crossrail 2, I said this about Crossrail 2 and the Northern Line.

Crossrail 2 will have interchanges with the Northern Line at Angel, Kings Cross St. Pancras, Euston, Tottenham Court Road, Tooting Broadway and possibly Clapham Junction. So it looks like that Crossrail 2 will certainly make journeys easier for users of the Northern Line.

This should mean that travellers on the Northern Line will be able to avoid a congested London Bridge tube station.

Victoria

Victoria tube station is being extended and rebuilt, which should result in sufficient capacity for more than a few years.

In Call For Crossrail 2, I said this about Crossrail 2 and the Victoria Line.

Crossrail 2 will effectively by-pass the central part of the Victoria Line as the two lines connect at Tottenham Hale, Seven Sisters, Kings Cross, Euston and Victoria.

This should take some of the pressure from Victoria tube station.

Waterloo

Waterloo tube station is a very busy tube station, as it has to cope with all the passengers using Waterloo station.

Crossrail 2 will allow passengers to bypass Waterloo, when travelling to and from Central London.

However, three major improvements will be delivered this year.

  • The old Eurostar platforms are being brought back into use.
  • Extra capacity is being added to the Underground station.
  • I also think that when they have completed the improvements at the Bank end of the Waterloo and City Line. 
  • Will improvements follow at the Waterloo end?

I think Waterloo shouldn’t be judged until the current round of work is completed.

Finsbury Park

Finsbury Park station is a station that suffered badly when the Victoria Line was tunnelled through in the 1960s.

Lifts are being installed, but extra services will be added.

  • Thameslink will call regularly at the station.
  • The services on the Northern City Line will become the Great Northern Metro with an increased frequency.

Crossrail 2 will provide relief for Finsbury Park, as it provides a by-pass for the Victoria Line.

But the station needs to have quite a bit of rebuilding.

Stockwell

Stockwell tube station is where the Victoria and Northern Lines meet South of Victoria.

This map from carto.metro.free.fr shows the lines at Stockwell station.

I’m not sure how Crossrail 2 helps here, but I suspect Transport for London hope that the new line will divert passengers away from Stockwell.

Stratford

Stratford station is another station that will be partially bypassed by Crossrail 2.

I do think that after Crossrail opens, that changes will be made at Stratford station to perhaps move some Liverpool Street services to Stansted and Cambridge.

This would bring more services to some not very busy platforms.

In West Anglia Route Improvement – The High Meads Loop, I described how it might all work.

This map from carto.metro.free.fr shows the lines in this area.

Trains from Cambridge and Stansted would arrive at Temple Mills East Junction and would go round the High Meads Loop dropping and picking up passengers in Platforms 11 and 12 bwfore returning North.

An extra platform could even be added to serve services in Stratford International station.

The tunnels under the platforms at Stratford station would probably need improvement, but who knows how Eastenders will duck and dive after Crossrail opens.

As an example, passengers from Shenfield to Canary Wharf will probably use the cross-platform change at Whitechapel station, rather than pick up the Jubilee Line or the DLR at Stratford.

Oxford Circus

Oxford Circus tube station has needed improvement for years.

Crossrail will give some relief, as there will be new additional entrances to Tottenham Court Road and Bond Street stations closer to Oxford Circus.

I did look at what might happen in What Will The Elizabeth Line Do For Oxford Street?.

I came to this conclusion about Crossrail 2 and Oxford Street.

Crossrail 2 has just one interchange in the Oxford Street area at Tottenham Court Road station.

I would be very surprised in that in the massive rebuilding of the current station for Crossrail, that provision hasn’t been made to connect to Crossrail 2.

There have been surface issues around the station concerned with Crossrail 2, but given good planning of the project, I feel that the building of Crossrail 2 would only effect the area in a similar way to the replacement of a major block on Oxford Street.

Crossrail 2 will have two major effects.

  • It will bring large numbers of visitors to the Oxford Street area.
  • Just as Crossrail and the Central Line will work as a high-capacity pair, it will work closely with the Victoria Line to relieve that line.

This leads me to the conclusion, that the wider Oxford Street area needs to be and will be pedestrianised.

In some ways preparation for the pedestrianisation has already started by reorganising the buses.

Oxford Circus tube station is also high on Transport for London’s improvement list.

This map from carto.metro,free.fr shows the lines through the station.

I suspect that if developers were interested in rebuilding any of the buildings on the South side of Oxford Street or perhaps even around the BBC to the North, that there could be arm-twisting and deal-making to sneak new entrances into Oxford Circus tube station.

Highbury & Islington

Highbury & Islington station, is one of my local ones and it is getting some much-needed improvement.

  • The Northern City Line will be getting frequent new Class 717 trains to create the Great Northern Metro.
  • Highbury Corner will be remodelled to improve pedestrian access to the station.
  • Bus and taxi access is being improved..

But nothing has been announced about improving the chronic access to the two deep-level lines at the station.

Speaking to staff at the station, they feel that a solution is possible, using the second entrance on the other side of the road.

In some ways the Great Northern Metro with its cross-platform interchange with the Victoria Line could be the saviour of this station, as it gives direct access to the City and to Crossrail at Moorgate station.

One of London’s forgotten lines could be riding to the rescue.

Clapham Common

Clapham Common tube station is one of my least favourite. This picture shows why.

It’s downright dangerous now, so when the Northern Line frequency is increased will the station cope?

Clapham North

Clapham North tube station is another dangerous island platform.

But at least the station has escalators.

In A Journey Round The Clapham Stations, a post I wrote in December 2015, I said this.

Having seen Clapham North and Clapham Common stations today, I do wonder if a diversion could be dug as at Angel, Bank and London Bridge, to create safe new stations. This new tunnel could surely be part of the works to add step-free access to one or both stations and connect the tunnels to Clapham High Street station.

What with the Northern Line Extension to Battersea, the rebuilding of Bank and Camden Town stations and all the resignalling of the past few years, the Northern Line could at last be fulfilling its potential.

This could go a long way to  sorting the problem of the Clapham stations.

Clapham South

Clapham South tube station is not as bad as the other two Clapham stations discussed earlier.

Crossrail 2 may reduce the level of overcrowding on the Northern Line trains through the three Clapham stations, as passengers could change at Balham or Tooting Broadway stations to and from the new high-capacity line.

However, nothing short of some serious building work will solve the island platform problems at Clapham Common and Clapham North stations.

Holborn

Holborn tube station is very busy, but is one that could benefit from Crossrail, due to that line’s relationship with the Cerntral Line.

Crossrail 2 will certainly benefit the station, as it will relieve the pressure on the Piccadilly Line.

But Transport for London have published plans to add a second entrance and full step-free access. This is a 3-Dview of the plans.

Note the second entrance will be in Procter Street.

The only problem is that it could be 2021 before a decision is made.

However as a Piccadilly Line station, Holborn will benefit from the New Tube For London, before the upgrade.

Warren Street

Warren Street tube station is another Central London station on the Victoria Line, that could benefit from Crossrail 2’s duplication of the Victoria Line.

Leicester Square

Leicester Square tube station is just one stop on the Northern Line from the major new interchange of Tottenham Court Road station, which will be served by both Crossrail and Crossrail 2.

The station has needed more capacity since I first used it in the 1950s.

It needs step-free access.

This map from carto.metro.free.fr shows the lines around Leicester Square station.

There is quite a tight knot of stations, of which only Tottenham Court Road has both escalators and lifts, although Goodge Street and Covent Garden have lifts only.

Leicester Square is an unusual station in that both the Northern and Piccadilly Lines are accessed by short passages and a short staircase from a fair-sized lobby at the bottom of a long set of escalators.

Clapham Junction

Clapham Junction station is the only non-Underground station in the seventeen stations named, where overcrowding could become chronic if Crossrail 2 is not built.

It is the busiest station by number of trains in Europe, so it must be difficult to keep on top of increasing numbers of passengers.

In the Wikipedia entry for the station under Future Proposals, this is said.

In 2007 the alignment of one of the two variants of Crossrail 2, that via the station rather than Putney and Wimbledon, was safeguarded. The Department for Transport and Transport for London continue to discuss proposal for a Clapham Junction Northern Line extension and its London Underground alignment has been legally reserved through Battersea Park, and would connect Clapham Junction to the London Underground for the first time.

Government and Network Rail funding for in the early 2010s of £50 million of improvements was granted. This comprised an upgrade to the main interchange: new entrances and more retail.

Surely something needs to be done, if Crossrail 2 is not built.

My proposals would include.

  • Developing the West London Line services.
  • Extending the Northern Line from Battersea Power Station station.
  • Improving the frequency of trains into Waterloo.
  • Make the station subway step-free.

There may be a need for more platforms, but the London Overground found this difficult.

This map from carto.metro.free.fr shows the platforms in the station.

Simple it isn’t!

Conclusions

It surprised me how many of these stations will need substantial building work to cure the overcrowding.

Note.

  1. Every Victoria Line station between Oxford Circus and Finsbury Park is on the list.
  2. Four Northern Line stations between Stockwell to Clapham South is on the list.
  3. I think this shows how the designers of the Northern and Victoria Lines didn’t expect the traffic the lines now handle.

But overall, I think it shows how when you design a station, you don’t cut corners.

I also think to blame all these problems on the uncertainty about Crossrail 2, is probably a bit strong.

Consider.

  • Liverpool Street will probably have enough capacity when Crossrail opens, especially as the station will incorporate Moorgate and be substantially step-free.
  • The new London Bridge effectively adds high-frequency rail lines to Blackfriars, Cannon Street, Charing Cross and St. Pancras and when Thameslink and Southeastern are fully developed, the station will cope.
  • Victoria shouldn’t be judged until the current upgrade is complete.
  • Waterloo shouldn’t be judged until the current upgrade is complete.
  • Finsbury Park shouldn’t be judged until the current upgrade is complete.
  • Stratford will probably have enough capacity when Crossrail  opens, especially as the station is substantially step-free.
  • Oxford Circus should see improvement when Crossrail opens, especially as there’ll be new step-free entrances to Tottenham Court Road and Bond Street, that will be closer to Oxford Circus, than the current stations.
  • Highbury & Islington should see marginal improvement, when the Northern City Line is updated.

However, nothing short of substantial construction will sort Euston, Clapham Common, Clapham North, Holborn, Leicester Square and Clapham Junction.

Every Picture Tells A Story!

The April 2017 Edition of Modern Railways has a picture of a  Crossrail Class 345 train on the High Meads Loop.

The main purpose of the High Meads Loop would appear to be to allow trains to go from Lea Bridge station through Platform 11 or 12 at Stratford station and then back to Lea Bridge without the driver changing cabs.

So what was the train doing?

  • I doubt it would have been running up the busy West Anglia Main Line, as even in the maddest scenarios, Crossrail will not be running there.
  • Could it have just been route proving on a line that other Aventras will use from 2018 or 2019?
  • Perhaps it was running to Broxbourne to assess performance for Crossrail 2.

But if it is was running on the High Meads Loop, as the picture caption says, was it testing that Aventras can be turned using the loop?

So could this mean that services from the  West Anglia Main Line terminating at Stratford will use the High Meads Loop rather than the Platforms 11 and 12.

Each of Platforms 11 and 12 could probably handle four trains per hour (tph), as is regularly handled by terminal platform on the London Overground.

But terminating in the High Meads loop, which would mean that all services would call at perhaps Platform 11 could give a capacity of upwards of 14 tph, as is the frequency on the Wirral Line on Merseyrail. But the Wirral Line was designed in the 1970s , so surely we can do better than that, as Crossrail and Thameslink will handle 24 tph and even the conventionally signalled East London Line will be handling 20 tph in 2019.

If it was 20 tph, this would mean that Platform 11 at Stratford could see a train every three minutes, possibly going to the following.

  • 4 tph to Walthamstow Central and Chingford via the Hall Farm Curve.
  • 8 tph to Broxborne
  • 2 tph to Hertford East
  • 2 tph to Bishops Stortford
  • 2 tph to Stansted Airport
  • 2 tph to Cambridge

In addition the following services could run from Liverpool Street.

  • 2 tph to Hertford East
  • 2 tph to Bishops Stortford
  • 2 tph to Stansted Airport
  • 2 tph to Cambridge

This sort of schedule would be possible given the following improvements and developments.

Signalling

Modern signalling as fitted to Crossrail and Thameslink is installed.

Stadler Flirts

Stadler probably have a good knowledge of the performance of the Flirts.

Current fastest timings are as follows.

  • Liverpool Street to Broxbourne – 25 minutes
  • Broxbourne to Cambridge – 45 minutes.

The Flirts will be faster than the current trains and will be optimised for a very fast stop at a station. So I do wonder what sort of times could be achieved between Bishops Stortford and Cambridge stopping at all stations.

Fast Lines To Broxbourne

Two separate non-stop fast lines will be built between Tottenham Hale and Broxbourne.

  • Cambridge and Stansted services take the fast line to Broxbourne.
  • All trains on the fast lines will be Stadler Flirts.
  • With fast line trains the first stop is Broxbourne.

The fast lines would also handle extra services from Liverpool Street, which might be 2 tph to each of Stansted Airport and Cambridge.

A summary of traffic on the fast lines between Tottenham Hale and Broxbourne could be.

  • 2 tph – Liverpool Street and Cambridge
  • 2 tph – Stratford and Cambridge
  • 2 tph – Liverpool Street and Stansted Airport
  • 2 tph – Stratford and Stansted Airport

There is probably a few paths for other trains.

North Of Broxbourne

North of Broxbourne the service will be very much better than now.

  • What helps is that both the Flirts and the Aventras will be masters of the quick stop-start at a station.
  • Stansted services will probably go non-stop from Broxbourne..
  • Some Cambridge services will go non-stop and others will stop at all stations.

I think it can be arranged that all stations North of Broxbourne get 4 tph in both directions.

A summary of traffic on the lines between Broxbourne and Bishops Stortford could be.

  • 2 tph – Liverpool Street and Bishops Stortford
  • 2 tph – Stratford and Bishops Stortford
  • 2 tph – Liverpool Street and Cambridge
  • 2 tph – Stratford and Cambridge
  • 2 tph – Liverpool Street and Stansted Airport
  • 2 tph – Stratford and Stansted Airport

A summary of traffic on the lines between Bishops Stortford and Cambridge could be.

  • 2 tph – Liverpool Street and Cambridge
  • 2 tph – Stratford and Cambridge
  • 2 tph – Liverpool Street and Stansted Airport
  • 2 tph – Stratford and Stansted Airport

There would also be additional Stansted Airport to Cambridge services.

Slow Lines

The slow lines will be upgraded to be able to handle 16 tph stopping at all stations between Tottenham Hale and Broxbourne, which they probably do now at times.

  • All trains on the slow lines are Aventras.
  • A second platform is built at Ware, as this would enable four tph to Hertford East.
  • Cross-platform interchange between slow and fast lines at Broxbourne.

A summary of traffic on the slow lines between Tottenham Hale and Broxbourne could be.

  • 8 tph – Stratford to Broxborne
  • 2 tph – Straford to Hertford East
  • 2 tph – Stratford to Bishops Stortford
  • 2 tph – Liverpool Street to Hertford East
  • 2 tph – Liverpool Street to Bishops Stortford

Crossrail 2 is proposing a frequency of 12 tph North of Tottenham Hale, so my randomly-chosen frequency gives you that.

Liverpool Street

Liverpool Street station will become the terminus for the following.

  •  Great Eastern Main Line.
  • 2 tph to each of Bishops Stortford,, Cambridge, Hertford East and Stansted Airport.
  • London Overground setvices to Cheshunt, Chingford and Enfield Town.
  • Perhaps a few c2c services.

Given that Liverpool Street and Stratford are just eight minutes away on Crossrail, is there any reason to keep West Anglia Main Line services at Liverpool Street?

But then, there are others who know more about train scheduling than me and perhaps a good balance can be made between the two termini.

Stratford International Station

If Stratford services used the High Meads Loop, a connection could be built to Stratford International Station.

Crossrail 2

Crossrail 2-like frequencies would have been created between Tottenham Hale and Broxbourne.

All it would need to complete Crossrail 2 after the suburban services out of Waterloo have been upgraded this summer, is to build the Central Tunnel.

Conclusion

Using the High Meads Loop is a good plan.

 

 

 

 

 

 

, Does that mean that Stansted and Cambridge services will be using Stratford as a terminal when Greater Anglia gets Aventras and Flirts?

 

Were they just seeing if it fits?

West Anglia Route Improvement – The High Meads Loop

This map from carto.metro.free.fr shows the lines at Stratford.

stratfordlines

Note Temple Mills East Junction at the Northern (top) end of the map.

If you go North from here, you are on the Temple Mills Branch of the West Anglia Main Line and you will pass through Lea Bridge station and Coppermill Junction before you reach Tottenham Hale station.

Go South from that Junction and you pass the crossover of Olympic Park Junction, cross over the Eastern End of Stratford International station and then arrive in Platforms 11 and 12 at Stratford station.

Platform 11 is used for the current two trains per hour (tph) that go up and down the West Anglia Main Line, but Platform 12 is currently just giving out messages saying “I’m Free!”

Platforms like these can generally handle four tph, as they do at stations like Highbury and Islington or Dalston Junction. But is a capacity of eight tph enough if some Stansted and Cambridge services are added to the mix at Stratford?

But there may be other possibilities!

On the map in this post, look  at the lines to the North-West of Platform 11 and 12 at Stratford station and how they curve round the Eastfield Shopping Centre and Stratford International station.

The main route is called the High Meads Loop and this picture taken from a Docklands Light Railway train to Stratford Internation station, shows the twin-track loop.

dscn9935

Southbound trains from Tottenham Hale could do the following.

  • Call at  Platform 1 in Lea Bridge station.
  • Call in Plastform 11 at Stratford station.
  • Go round the High Meads Loop and past the Stratford International DLR station.
  • Rejoin the Temple Mills Branch on the Down Line at Temple Mills East Junction.
  • Call at  Platform 2 in Lea Bridge station.

The train has been turned round using the High Meads Loop, after a stop at Platform 11 in Stratford station.

So do trains currently take this route?

On this page in RailForums, this was said in a post made in 2006.

Another option is the use of Channelsea Junction and the High Meads loop to turn trains at Stratford. I’ve managed to go from Stansted Airport to Stratford and back again without changing ends using that particular route before now.

I would assume from the words, the poster of the information is a driver. So they should know!

Channelsea Junction is clearly shown on the map in this post.

I have a few questions, that should be answered.

Is The Route Bi-Directional?

I suspect it is and trains would call in the unused Platform 12 at Stratford station. As I said in Platforms 11 and 12 At Stratford,

Trains stopping in Platform 12, will have a very simple step-free access to the London Overground services in Platforms 1 and 2.

My personal view, would be that services using the loop called in Platform 12, as that would give me easy access from the North London Line from where I live.

But going round this way through Platform 12 at Stratford would mean that trains would have to cross on the flat at Temple Mills East Junction.

How Long Are Platforms 11 and 12 at Stratford?

They certainly accept an eight-car train as they do now, but would they accept a twelve-car one?

The Picture Says 8

The Picture Says 8

If they can’t and it would be needed to accept Greater Anglia’s new Stadler Flirts for the Stansted Express, there would appear to be space to lengthen the platforms, at the Temple Mills End.

It has to be asked if Platforms 11 and 12 have enough capacity.

I would appear that they have been built reasonably wide to accept  high passenger numbers.

What Services Could Use This Loop?

I suspect any service arriving at Stratford from the West Anglia Main Line, that needed to be turned back, could use this route.

  • Angel Road using the new STAR service.
  • Bishops Stortford
  • Broxbourne
  • Cambridge
  • Chingford using the Hall Farm Curve.
  • Hertford East
  • Stansted Airport

That is a very comprehensive list.

How Many Trains Per Hour Could Use The Loop?

The capacity of the loop could be at least as high as the similar Wirral Loop in Liverpool, which handles 12 tph or just one train every five minutes.

Modern signalling with a measure of Automatic Train Control could probably raise this figure substantially.

In addition, Platform 11 could probably handle four tph as it does now.

Could A Station Be Built On The High Meads Loop To Serve Stratford International?

If it could, it would ease one of London’s truly dreadful transport issues. How do you get to Stratford International station without walking a long way or going through Eastfield?

Can Services Using Platforms 11 and 12 At Stratford Access The North London Line?

As there is a triangular junction connecting the North London Line, the High Meads Loop and Platforms 11 and 12 at Stratford, a lot of services are possible, if they are needed.

But for the time being a good step-free interchange between Angel Road, Chingford and other services from the West Anglia Main Line to the North London Line services at Stratford is all that could be needed.

If High Meads Loop services called in Platform 12 at Stratford, that would be an ideal solution.

A short walk would connect North London Line services to Stanstead Airport services and local trains up and down the West Anglia Main Line.

Note the sign in this pictuire.

It directs passengers to Platform 12 for Stansted Airport services.

How Many Trains Per Hour Could Use The Loop?

The capacity of the loop could be at least as high as the similar Wirral Loop in Liverpool, which handles 12 tph or just one train every five minutes.

Modern trains and signalling with a measure of Automatic Train Control could probably rise this figure substantially.

So perhaps there could be twelve to fifteen tph through platform 12.

In addition, Platform 11 could probably handle four tph as a traditional terminal platform.

Do Any Other Services Use The Temple Mills Branch?

I’m not saying they don’t, but I’ve never a freight train go through Platform 11 or 12 at |Stratford or Tottenham Hale or Lea Bridge station.

But I have seen an engineering train at Coppermill Junction and empty stock needs to get in and out of Temple Mills Depot.

Conclusion

Trains arriving at Stratford station on the Temple Mills Branch of the West Anglia Main Line can call at Stratford station and go straight back from whence they came using the High Meads Loop.

One positive effect would be that however many trains went round the High Meads Loop, all could call at the following stations.

  • Platform 1 at Lea Bridge station
  • Platform 11 or 12 at Stratford station
  • A platform at Stratford International station, if it were to be built.
  • Platform 2 at Lea Bridge station

Look at the service that Lea Bridge station gets to and from Stratford.

West Anglia Route Improvement – What Is STAR?

STAR stands for Stratford-Tottenham-Angel Road and is a proposed four trains per hour (tph) service between Stratford and Angel Road stations, calling at the following stations.

The main purpose is to provide a service to the new £3.5billion housing and commercial development project at Meridian Water, the developers of which will be rebuilding Angel Road station and renaming it to Meridian Water.

Brief details of the project are given in the March 2017 Edition of Modern Railways.

  • STAR will involve laying a third track between Stratford and Angel Road, alongside the West Anglia Main Line and the Temple Mills Branch to Stratford.
  • STAR will be completed at the end of 2018.
  • STAR will run at a frequency of four trans per hour (tph)
  • STAR  will help in the four-tracking of the West Anglia Main Line.

More will certainly emerge in the next few months.

But I have a few questions about STAR.

Will STAR Services Go Beyond Angel Road Station?

The only STAR service at present is the two tph service to either ?Hertford East or Bishops Stortford stations that call at Lea Bridge, then in a rather haphazard pattern up the Lea Valley.

It is not a passenger-friendly service, as you turn up for the half-hourly train and find the destination you want is served on the alternate service.

I have a feeling the service pattern is designed by history, rather than a train planner with a brain.

What Type Of Train Will Be Used?

I think the route STAR will take, has a possible headroom problem at Tottenham Hale.

Ferry Lane Bridge At Tottenham Hale Station

Ferry Lane Bridge At Tottenham Hale Station

When I first saw this bridge and saw the height of the overhead electrification on the existing West Anglia Main Line under the far span, I immediately questioned if they could fit the electrification under either of the blue steel bridges, where STAR might pass, in a manner that would meet all the Health and Safety regulations.

Read this article on the Rail Engineer web site, which is entitled EGIP – electrification clearance woes, to learn more about how regulations are making electrification not just an engineering problem.

So will this mean that STAR will be built without wires?

Diesel trains would work, but wouldn’t fit the profile of Meridian Water as an ecologically-sound development.

I think we could see IPEMUs or electric multiple units with onboard energy storage working the route.

Will STAR Share Platforms With The West Anglia Up Line?

The space for putting the third track for STAR is narrow as this picture at Tottenham Hale shows.

 

Not Much Space For Two Tracks

STAR Will Go Through Here At Tottenham Hale Station

If STAR goes through in the space conveniently marked by green grass, the easiest way to create a platform would be to add a second face on the existing Platform 1.

  • A step-free bridge is being built linking Hale Village to a new station building with step-free access to the existing Platforms 1 and 2.
  • If STAR used the other face of Platform 1, it would share the step-free access of that platform.
  • STAR would have cross-platform access with services to Liverpool Street.
  • There would be step-free access between STAR and the Victoria Line.

It could be a very simple and affordable way of creating a new platform and interchange with full step-free access.

The technique could also be used at Northumberland Park station.

Could STAR Call At Stratford International Station?

One of the many proposals for the Docklands Light Railway was to extend the Stratford International Branch along the Lea Valley. This seems to have been dropped.

But there is a line called the High Meads Loop, that  would appear to allow trains to call at Lea Bridge station and Platform 11 at Stratford station, before looping round Eastfield and Stratford International station and returning through Lea Bridge station. In a forum, a claim is made by I assume a driver, that he’s done this.

If a platform could be built on the High Meads Loop to serve Stratford International station, then STAR services could go round the High Meads Loop and call at the platform.

But if the loop could be used to turnback trains, then it would allow a lot more trains to use Stratford as a destination.

Could A Similar Service To STAR Connect Stratford To Walthamstow And Chingford?

I have been past the work-site between Lea Bridge station and Coppermill Junction several times in the last few days and it would appear that the Hall Farm Curve that would make this service possible is being cleared of fifty-plus years of rubbish.

But, there are other problems in creating this service, like the level crossing at Highams Park station.

Could The Capacity Of STAR Be Increased?

The capacity on the East London Line, which runs a similar 4 tph service on four separate routes, was increased by the simple process of lengthening the trains.

Provided the platforms are built to accept longer trains, this would be the easy way to increase capacity.

What Will Happen To STAR When The Great Anglia Main Line Is Four-Tracked?

STAR will only affect the West Anglia Main Line between Coppermill Junction and Angel Eoad, as this is the only section, where the STAR and the new lines will co-exist.

In How Many Fast Services Will Go Through Tottenham Hale Station?, I concluded that there will be between ten and twelve fast trains per hour in both directions between Tottenham Hale and Broxbourne stations.

I also think, that these trains will go non-stop along the new lines only stopping at Broxbourne, as the timings of the new slow trains could be the same as the current fast ones. See Timings Between Tottenham Hale And Broxbourne Stations for full details.

As the four-tracking will not take place for a few years, I think it is likely that Stadler and Bombardier will be able to fit onboard storage to their trains, so could we see the two new lines squeezed into the small space between STAR and the development at Tottenham Hale without electrification?

Signalling technology would also probably allow such a line to be bi-directional, with trains running alternatively in both directions.

It would certainly save space to have a single bi-directional line without electrification handling the fast trains through Tottenham Hale!

The fast line would revert to a normal double track at Coppermill Junction and Angel Road station.

As closing a rail route is often a difficult process, even after Crossrail 2 is providing a high frquency service between Tottenham Hale and Angel Road, STAR will continue into the future.

Conclusion

STAR is putting down some interesting markers for the future.

West Anglia Route Improvement – Modern Railways March 2017

The March 2017 Edition of Modern Railways sheds some more light on what is happening at the between Angel Road and Tottenham Hale stations.

They state  the following about the current works.

  • The Stratford area and its station is growing in importance.
  • The line is slated for improvement under the Stratford-Tottenham-Angel Road (STAR) project.
  • STAR will involve laying a third track between Stratford and Angel Road, alongside the West Anglia Main Line and the Temple Mills Branch to Stratford.
  • STAR will be completed at the end of 2018.
  • STAR will run at a frequency of four trans per hour (tph)

A picture in the magazine taken from a footbridge shows very much what my pictures show.

They also state this about Crossrail 2

  • Crossrail 2 would be overlaid on the existing network serving both Liverpool Street and Stratford stations.
  • Coppermill junction could be converted to a grade-separated rather than a flat junction.
  • Crossrail 2 would emerge from the tunnel South of Tottenham Hale.
  • The project would quadruple the West Anglia Main Line from the tunnel portal to Broxbourne.
  • STAR would be built to facilitate this.
  • A turnback platform is being considered at Tottenham Hale
  • A turnback platform is being considered at Enfield Lock
  • Turnback platforms and stabling sidings are considered at Broxbourne.

So how does all this fit with my observations?

STAR

I very much feel that STAR could be only a stop-gap development until Crossrail 2 arrives. In What Is STAR?, I give a few basic details.

After all will it still be needed to run just four tph between Angel Road and Stratford, when there could be upwards of 10-15 tph on Crossrail 2 and other services between Tottenham Hale and Stratford?

Something is needed immediately to serve Angel Road station and the massive Meridian Water development, which will result in the renaming of Angel Road station to Meridian Water,

The timings from Tottenham Hale are currently as follows.

  • Stratford – 14 minutes
  • Lea Bridge – 4 minutes
  • Northumberland Park – 2 ,minutes
  • |Angel Road – 4 minutes

Modern Railways states STAR will use a third track between Stratford and Angel Road. So if it was designed to be straight and flat and if it is running new Aventra trains from either London Overground or Greater Anglia with a fast stop capability, I wonder if timings could be achieved, which would enable just two trains to run the required service.

But I also suspect that STAR would provide a valuable service to link Meridian Water to Tottenham Hale and Stratford stations, even after Crossrail 2 opens.

STAR At Tottenham Hale

This picture shows the available space at Tottenham Hale station, which doesn’t appear to be enough for two lines.

Not Much Space For Two Tracks

Note the newly-installed cable ducts.

Modern Railways states STAR will use a third track between Stratford and Angel Road. A single track would certainly fit through here.

Suppose the current platform 1 on the left, was made an island platform for the existing London-bound line and the track for STAR going along the route that now almost looks like freshly-mowed grass.

  • The new platform could be Platform 0
  • STAR would be worked in a bi-directional  manner, always calling at Platform 0
  • When Tottenham Hale station is re-built in the near future, Platform 0 will have full step-free access to the Victoria Line, courtesy of Platform 1.
  • It would have cross-platform access to Liverpool Street services on Platform 1.
  • Moving some Stansted or Cambridge service from Liverpool Street to Stratford might be operationally worthwhile after Crossrail opens.

Platform usage at Tottenham Hale would be as follows.

  • 0 – All STAR services.
  • 1 – Services to Liverpool Street
  • 2 – Northbound services except STAR.

That would be very logical for passengers and not the most complicated of construction projects.

STAR At Angel Road

If the third track continued to Angel Road station as seems to be proposed, then a  single bay platform could handle the four tph.

Space would have to be left for the two future new lines that will be installed, when the full West Anglia four-tracking takes place.

The STAR track could be close to the current West Anglia Up Line, as it will be at Tottenham Hale with the two new lines on the Eastern side of the station.

If the STAR track was on the outside, there would have to be a flat junction, where the STAR track crossed the two extra lines.

Until Crossrail 2 is built, I also suspect that STAR could be only service calling at Angel Road.

So there will be a lot of flexibility on how the station is built.

STAR At Northumberland Park

This picture shows the current works at Northumberland Park station.

Northumberland Park Station

This picture was taken from the footbridge in the station.

Could the current platform 1 at the station be converted into an island platform between the current West Anglia Up Line and a STAR track between the West Anglia Main Line and the Northumberland Park Depot for the Victoria Line?

I suspect the answer is in the affirmative.

There might even be space for more lines through the area, when the West Anglia Main Line is four-tracked.

STAR At Lea Bridge Station

Lea Bridge station is a recently-opened station on the Temple Mills Branch between Tottenham Hale and Stratford and I doubt  there is sufficient space for a separate track for STAR with its own platform through the station.

This picture is from A Look At Lea Bridge Station, which shows the station in detail.

 

Alongside Lea Bridge Station

 

The STAR track would have to go through here and would probably mean substantial rebuilding of a brand-new station.

So all services to Stratford will call at Platform 1 and all services from Stratford will call at Platform 2.

This will mean a junction North of Lea Bridge station, so that services can get themselves to the right lines for Tottenham Hale or in future the Chingford Branch along a rebuilt Hall Farm Curve.

  • Southbound STAR, Chingford Branch Line and other services to Stratford will merge before Lea Bridge station to pass through Platform 1.
  • Northbound STAR and Chingford Branch Line services will pass through Platform 2 and then cross over the Temple Mills Branch Up Line to the bi-directional STAR track alongside the main lines to Tottenham Hale.
  • Northbound Chingford Branch Line services will take the Hall Farm Curve to get to St. James station and the Chingford Branch Line.
  • Other Northbound services from Stratford will stay on the Temple Mills Branch Down Line and go straight to Platform 2 at Tottenham Hale.

Traffic crossing from the Temple Mills Branch Down Line over the Up Line to get to the STAR track would include.

  • STAR services of four tph.
  • Services from Stratford to Walthamstow and Chingford, which could be between two and four tph.

Due to restrictions on capacity caused by the level crossing at Highams Park station on the Chingford Branch Line, I suspect this could initially be just 2 tph, until a solution for the restriction is found.

STAR at Stratford

One possible problem is the capacity at Stratford station, which only has two possible terminal platforms 11 and 12.

Platform 11 is used for the current two tph that go up and down the West Anglia Main Line, but Platform 12 is currently just giving out messages saying “I’m Free!”

Platforms like these can generally handle four tph, as they do at stations like Highbury and Islington or Dalston Junction. But is a capacity of eight tph enough if some Stansted and Cambridge services are added to the mix.

But there may be other possibilities!

In High Meads Loop, I look at how an existing loop around Eastfield and Stratford International station could be used to turn trains.

This map from carto.metro.free.fr , shows the High Meads Loop.

stratfordlines

Use of the High Meads Loop would enable the following.

  • Probably upwards of 10-12 tph to be turned back at Stratford.
  • Trains would call in either Platform 11 or 12 at Stratford station.
  • Trains could call at Stratford International station.

Currently Platforms 11 and 12 can only handle eight-car trains, but they could be lengthened for the the new 12-car Stadler Flirts, that will work the London to Cambridge and Stansted services in a couple of years.

Cambridge, Stansted and Lea Valley services would have simple changes to the following services at Stratford.

  • Central Line
  • Crossrail for City and East London, Essex, Heathrow, Paddington and the West End.
  • DLR for Docklands and South East London.
  • European services, if they were to call at Stratford International. As they should!
  • Greater Anglia for Chelmsford, Colchester, Ipswich, Norwich and all the branches.
  • Jubilee Line for Canary Wharf, London Bridge, Waterloo and Westminster.
  • North London Line for Clapham Junction, Old Oak Common and West and South West London.
  • Southeastern Highspeed to Ebbsfleet, Kent and East Sussex.

I suspect that London Overground and/or Greater Anglia have a cunning plan to collect all of these services and platforms together in an optimal manner for the benefit of all stakeholders.

But it’s really just the East End of London asserting its true place in London’s hierarchy.

The Stratford/High Meads Advantage

Using the High Meads Loop at Stratford to turn trains from the West Anglia Main Line could be a big advantage in the next few years.

All of these construction projects need to be carried out.

  • Rebuilding of Tottenham Hale station.
  • Updating of Coppermill Junction.
  • Four-tracking of the West Anglia Main Line.
  • Lengthening of platforms at Liverpool Street station.
  • Connection of Crossrail 2 to the West Anglia Main Line.

If a connection between Tottenham Hale and Stratford  via Lea Bridge can be maintained at all times during this massive amount of construction, which given the space available is very possible, then Stratford could be an alternative destination for diverted West Anglia Main Line and local services, that are unable to connect to Liverpool Street.

STAR And Electrification

This picture shows where the single STAR track will pass under the Ferry Lane Bridge at Tottenham Hale station

Ferry Lane Bridge At Tottenham Hale Station

When I first looked at this bridge and saw the height of the overhead electrification on the existing West Anglia Main Line under the far span, I immediately questioned if they could fit the electrification under either of the blue steel bridges, where STAR might pass, in a manner that would meet all the Health and Safety regulations.

The only way to electrify and be certain of the safety would be to replace the bridge with a modern structure. But this would take a couple of years and can it be built without closing an important route to and from London for a couple of months?

So I come to the conclusion that the STAR line will not be electrified and the line will use electric trains with onboard energy storage or IPEMUs.

  • I have been told by the manufacturer that all Aventra trains are wired for onboard energy storage.
  • Both possible operators of the star service; Greater Anglia and London Overground are obtaining sizeable fleets of suitable Aventra trains,
  • Greater Anglia’s Aventras are five-car trains.
  • London Overground’s Class 710 trains are four-car trains.
  • Delivery of London Overground’s trains is scheduled to start in 2018, so they are a just-in-time delivery.
  • The route between Lea Bridge and Stratford is fully electrified, so trains could charge the batteries South of Lea Bridge station.
  • Diesel trains would be an alternative, but probably not appropriate in the Lea Valley.

For added safety, the well-proven method of slab track will be used under the bridge to ensure the train stays stable.

The outcome will be the ecologically sustainable development of Meridian Water gets appropriate electric trains to shuttle residents to Crossrail and the Eastfield Shopping Centre at Stratford.

Crossrail 2

I shall make a few comments about what the article says about Crossrail 2.

Crossrail 2 Would Be Overlaid On The Existing Network

How else is there to do it without building a whole new line on a different route up the Lea Valley?

Incidentally, plans used to exist for extending the Chingford Branch Line to Stansted Airport through Epping Forest. I doubt that will ever happen, especially as Queen Victoria is supposed to have said no!

Coppermill Junction Could Be Converted To A Grade-Separated Rather Than A Flat Junction

These pictures were taken from a train, that was going from Lea Bridge to Tottenham Hale, through the area of Coppermill Junction.

At present the following happens at Coppermill Junction.

  • Trains between Liverpool Street and Chingford pass straight over the junction.
  • Trains from Liverpool Street to Tottenham Hale curve left from the Chingford Branch Line to join the West Anglia Main Line.
  • Trains from Tottenham Hale to Liverpool Street cross in a flat junction over the West Anglia Down Line and the Chingford Branch Down Line to get on track for Liverpool Street.

When the West Anglia Main Line has been four-tracked and the STAR track has been inserted alongside the current tracks, the fast tracks will probably be the two most Easterly tracks through Tottenham Hale.

This will mean that the West Anglia Up Fast will have to cross the following lines to get on the Chingford Up Line.

  • The bi-directional STAR line.
  • The double-track of the Temple Mills Branch to Stratford.
  • The Chingford Down Line.

In the opposite direction, the following tracks will have to be crossed.

  • The double-track of the Temple Mills Branch to Stratford.
  • The bi-directional STAR line.

These movements will need a very complicated Coppermill Junction.

As four-tracking is all about faster services between Liverpool Street and Cambridge and Stansted, it would be detrimental to not have an efficient Coppermill Junction, with some grade separation.

I think we probably need flyovers or dive-unders on the following routes.

  • West Anglia Up Fast to Chingford Branch Up.
  • Chingford Branch Down to West Anglia Down Fast.

Routes would probably need to be provided so that the trains could go between the West Anglia Slow Lines and the Chingford Branch towards London.

In addition, I’ve heard rumours that trains will be able to go both ways between Tottenham Hale and Walthamstow/Chingford.

There is certainly lots of space to build a complicated junction, as the pictures show.

Crossrail 2 Would Emerge From The Tunnel South of Tottenham Hale

I think that has been known for some time and the possible site is full of London’s demolition rubble.

However, the junction with the West Anglia Slow Lines would probably need to be grade separated and integrated with the spaghetti that Coppermill Junction will probably have become.

The Project Would Quadruple The West Anglia Main Line From The Tunnel Portal To Broxbourne

If fast services to Cambridge and Stansted are to be retained, surely this must be done.

Just imagine 10-15 Crossrail 2 trains and ten fast trains, every hour sharing a pair of lines up the Lea Valley.

In my view the fast lines would be the two most Easterly lines and they probably wouldn’t stop very often, if at all between Liverpool Street or Stratford and Broxbourne.

,

STAR Would Be Built To Facilitate Four-Tracking

Everything I’ve seen leads me to think, that the single STAR track will be next to the West Anglia and Temple Mills Branch Up Line, with the two new lines outside to the East.

I also feel that these new lines will be the fast ones and possibly will have few if any platforms between Tottenham Hale and Broxbourne.

STAR could be an independent line, well out of the way operationally of other lines.

  • STAR will be bi-directional North of Lea Bridge station.
  • STAR could share island platforms with the West Anglia Up Line at Angel Road, Northumberland Park and Tottenham Hale stations.
  • There could be no points on the route once it separates North of Lea Bridge station.
  • The fast lines between Liverpool Street and Tottenham Hale could cross the Temple Mills Branch and the STAR line at Coppermill Junction using a flyover.

The last point probably explains the grade-separated junction, I mentioned earlier.

I said earlier that it could be difficult to put extra tracks through Tottenham Hale station. These pictures show the area, where the STAR line and the two new lines will go and also what lies on the other side in the new housing development of Hale Village.

There is more space than I thought earlier. As some of the concrete decking will probably be demolished or modified to build the new entrance and pedestrian bridge for the station, I suspect that the space between the current station and Hale Village can be made wide enough for at least the new lines needed to four-track the West Anglia Main Line.

But I suspect that a way will be found to get the STAR line and the two other lines in what space can be created.

This would mean.

  • The STAR service can continue, as long as it’s needed.
  • There certainly wouldn’t be space for platforms on the two other lines between the current station and Hale Village.
  • So as the slow lines will need platforms, the two new lines will be the fast lines.

North from Tottenham Hale, there is slightly more space, as my picture at Northumberland Park station showed.

As the STAR line is currently planned to terminate at Angel Road station, North from there, the requirement is only the easier one of two tracks and not three.

But if the requirement for three tracks should prove too difficult, as the four-tracking will see Crossrail 2 implemented, I’m sure that the STAR line can be sacrificed to make space. But that would create difficulty in maintaining an adequate service between Angel Road and Stratford whilst the four-tracjing is being carried out.

In some ways STAR has the feel of one of those temporary diversions you get in road works to keep the traffic moving.

  • Tottenham Hale station is going to be rebuilt.
  • Transport is needed urgently for Meridian Water.
  • STAR connects Angel Road to Stratford with all its connections and Crossrail from 2018.
  • When Crossrail 2 is opened, Angel Road, Northumberland Park and Tottenham Hale stations will have a frequent high capacity service.
  • Greater Anglia might move some Cambridge and Stansted services from Liverpool Street to Stratford.

I wouldn’t be sure that STAR  would still exist after Crossrail 2 opens.

  • There will be well upwards of ten tph Crossrail 2 trains in both directions calling at Angel Road station.
  • STAR connects Meridian Water with Stratford.
  • STAR gives a four tph connection between Crossrail 2 at Tottenham Hale and Crossrail at Stratford.

Passenger numbers and patterns will decide.

A Turnback Platform Is Being Considered At Tottenham Hale

Tottenham Hale station is being rebuilt and I suspect that if a turnback platform is being considered the station will have provision for the extra platform to be built.

This picture shows the Southern end of Platform 2 at the station with the Ferry Lane Bridge behind.

dscn0039

It certainly couldn’t be described as good engineering.

Connecting the two current platforms is a 1960s bridge, which has steps at both end and a single escalator to bring passengers arriving from the North onto the bridge to walk to the Victoria Line.

Plans for the station envisage a lot of work being done before the end of next year. Future in the Wikipedia entry for the station includes these plans.

  • creating a new landmark entrance to the Station;
  • increasing the capacity of the Station concourse, by doubling the size of the current ticket hall;
  • improving interchange by relocating the Greater Anglia and London Underground gatelines;
  • providing new access to platforms via the new Access for All (AfA) bridge being delivered separately by Network Rail;
  • removing the existing subway which links the south side of Ferry Lane with the Station;
  • extending the existing bridge to form a new Station entrance from Hale Village, providing improved access from the east to Tottenham Hale transport interchange;
  • re-routing the London Underground escape route and relocating the vent shaft;
  • providing a new, upgraded Station control facility; and
  • retail units.

Nothing is said about a turnback platform.

But I think if the Ferry Lane Bridge was to be rebuilt and the new station was modified appropriately, the turnback platform could be positioned behind and alongside the current platform 2.

  • It would share step-free access with that provided for platform 2.
  • There would be cross-platform for passengers arriving in the turnback platform, with services going further down the line.
  • The current waiting room would be demolished.
  • There would be space for the platform.

Current works at the station are moving the taxi rank, which would help the provision of a turnback platform and other features.

A Turnback Platform Is Being Considered At Enfield Lock

When I looked at Enfield Lock station, I showed this Google Map of Enfield Lock station.

enfieldlock2

Given that there will be two extra lines through the area, will there be any space for a turnback platform?

In Level Crossing Issues, I said this.

The Southernmost three of these crossings; Enfield Lock, Brimsdown and Northumberland Park, are close to the A1055 which is variously called Meridian Way or Mollison Avenue, which was built to serve the various industrial and residential sites between Tottenham Hale and Waltham Cross.

This road should obviously be improved, but look at this Google Map of the Northern End of the road.

Note the West Anglia Main Line crossing the map, in a North-South direction. Waltham Cross station is on the other side of the M25.

Surely this could be a site for a new Park-and-Ride station for Crossrail 2!

Could this be where the turnback platform at Enfield Lock will be located in a new station?

Turnback Platforms And Stabling Sidings Are Considered At Broxbourne

Broxborne station has everything needed to be turned into a superb Northern terminus for Crossrail 2.

  • The station has four platforms; two fast and two slow, with cross-platform change.
  • The station is step-free.
  • There is space to add extra through and turnback platforms.
  • There is space for stabling sidings.
  • There is space for masses amounts of parking.
  • The station has a large water feature including the River Lea and the New River.

The station is even Grade II Listed.

I said more in this post called Broxbourne Station. The final paragraph is.

It would not need a massive amount of money to be spent at Broxbourne to make the station a superb Northern terminus for Crossrail 2. It makes Shenfield and Abbey Wood look decidedly second-class now.

It is not often that the terminus of a new rail line is so easy to develop.

Other Questions And Issues

As I have written this post, several questions and issues have suggested themselves.

  • What will be done about the noise of 100 mph plus trains every few minutes on some parts of the route, like through Enfield Lock and Waltham Cross?
  • Could the two new fast lines be placed in a cut-and-cover tunnel through Tottenham Hale?
  • Do any plans exist for the replacement of the Ferry Lane Bridge at Tottenham Hale?
  • Could the High Meads Loop be used to turn trains at Stratford?
  • Will a station be built on the High Meads Loop to serve Stratford International station?

Like Coppermill Junction, it will all get very complicated.

Conclusion

STAR, Crossrail 2 and four-tracking the West Anglia Main Line will probably bring a lot of benefits, but it is not a simple project.
