The Anonymous Widower

Greater Anglia’s Norwich And Stansted Airport Service Starts On December 15th 2019

The annual December timetable change on December 15th 2019, will see Greater Anglia bringing in their new service between Norwich and Stansted Airport stations start as an hourly service.

The Route

Between Norwich and Ely stations, the route is on the Breckland Line.

  • It is not electrified, except for a short section at the Norwich end.
  • It is a full double-track, except for the single-track Trowse Bridge, that it shares with the Great Eastern Main Line on the approach to Norwich.
  • The operating speed is between 75-90 mph.
  • There are intermediate stations at Shippea Hill, Lakenheath, Brandon, Thetford, Attleborough, Spooner Row and Wymondham.

There is potential to increase the line speed, perhaps add some extra stations and remove the antiquated Trowse Bridge.

South from Ely through Cambridge to Stansted Airport, the route is a busy, fully-electrified double-track line.

The New Timetable

The Sunday journeys are as follows

  • Journey time appears to be a couple of minutes over two hours both ways.
  • Most services seem to leave Stansted at XX:09
  • First Northbound train is 08:18
  • Last Northbound train is 21:11
  • Most services seem to leave Norwich at XX:03
  • First Southbound train is 09:03
  • Last Southbound train is 20:03
  • Calling points appear to be Audley End, Wittlesford Parkway, Cambridge, Cambridge North, Ely, Brandon, Thetford, Attleborough and Wymondham.

Weekday services appear to be more-or-less similar.

  • Northbound services take around 6-9 minutes less than two hours.
  • Most services seem to leave Stansted at XX:48
  • First Northbound train is 05:27
  • Last Northbound train is 21:11
  • Southbound services take around 3-9 minutes less than two hours.
  • Most services seem to leave Norwich at XX:27 or XX:33
  • First Southbound train is 08:33
  • Last Southbound train is 19:27
  • Calling points are the same.

My Observations follow.

Convenience And Capacity

It is currently actually quicker by a few minutes to use the following services.

  • East Midland Railway’s service between Norwich and Ely
  • CrossCountry’s service between Ely and Stansted Airport.

These two trains can be very overcrowded at times and the new four-car Class 755 trains are much better and have more capacity, than the other services, which are often just two-car Class 158 or Class 170 trains.

Two Trains Per Hour Between Norwich And Stansted Airport

It also appears that the service with the single change at Ely will still be possible after the timetable change.

Thjis means that Norwich and Stansted Airport will have a two trains per hour (tph) service.

Train Timings

It would appear that the times between Cambridge and Norwich are very similar before and after the timetable change.

So it doesn’t appear that Greater Anglia are taking advantage of the superior performance of the new Class 755 trains.

How Many Trains Will Greater Anglia Need For The Norwich And Stansted Airport Service?

The current service between Norwich and Cambridge stations has a three hour round trip, so three trains are needed to provide the hourly service.

It looks like the Norwich and Stansted Airport service has a four hour round trip, so four trains will be needed to provide the hourly service.

Extending the Norwich and Cambridge service to Stansted Airport needs just one extra train.

How many extra passengers will Greater Anglia attract?

Whittlesford Parkway Gets An Extra Hourly Service To And From Cambridge

The extended hourly service between Norwich and Stansted Airport will call at Whittlesford Parkway station, which will increase the frequency on the busy commuter route between the Parkway station and Cambridge City Centre.

When we lived near Newmarket and C was practising as a barrister, she would sometimes go to Norwich up to tyree times a week. I wouldn’t be surprised to find that travellers between Whittlesford Parkway and Norwich stations are rather more numerous than the forecast.

  • The train will take about ninety minutes and driving about seventy-five.
  • The Class 755 trains have wi-fi.
  • There is a lot of parking at Whittlesford Parkway station.
  • Will Greater Anglia put a snack trolley on the train?

C would have certainly used the service, as Whittleford Parkway station was around fifteen minutes from where we lived.

What Will Greater Anglia Do With Lakenheath And Shippea Hill Stations?

These two stations are By Request and only get a few services a week.

Consider.

  • The modern Class 755 trains with their high performance and short dwell times could probably selectively stop at these stations without degrading the train timings.
  • Cambridge needs satellite development to provide housing and commercial development.
  • The future of RAF Mildenhall is uncertain and it could be sold for housing.
  • It could be argued that Cambridge needs a new Park-and-Ride station to the North to take the pressure off Ely station.

This Google Map shows RAF Lakenheath and the Breckland Line running Easy-West between Ely and Norwich.

Note.

  1. RAF Mildenhall is to the South-West of RAF Lakenheath.
  2. The railway going across the North side of the map through Shippea Hill, Lakenheath and Brandon stations.
  3. Most of the land is aricultural and very flat.

I wouldn’t be surprised to see substantial development of the railway through the area in the next ten or twenty years.

What Will Greater Anglia Do With Spooner Row Station?

Spooner Row station is another By Request station on the Breckland Line bertween Attleborough and Wymondham stations..

Spooner Row is not a busy station, although as this Google Map shows it is just off the main A11 road.

Noyr that Spooner Row station is in the South-East corner of the map.

Perhaps with more services and some increased car parking, it might pick up commuters and shoppers for Cambridge and Norwich it might become a convenient station for local residents travelling to and from Stansted Airport.

Could There Be A Norwich And Dereham Service?

Greater Anglia seems to be working closely with the Mid Norfolk Railway, which runs between Wymondham station on the Breckland Line to the town of Dereham.

  • In Aerial Pictures Show New Trains Housed In Mid-Norfolk, I showed how the heritage railway was storing trains for Greater Anglia.
  • According to Wikipedia, it would appear that several million pounds were spent to i8mprove the railway and its signalling, so that Greater Anglia’s new trains could be safely stored.
  • The line is mainly single track and signalled for an hourly service.
  • The yard at Dereham station seems to be regularly used for freight purposes, including loading damaged rolling stock on to road vehicles. It is also used by Network Rail for storage of track plant.
  • Train operating companies and heritage railways are increasingly working together for their mutual benefit.

As an InterCity 125 trains has recently been beyond Dereham, I wouldn’t rule out Greater Anglia running a new service between Norwich and Dereham, with a future aim of extension to Fakenham.

Because of the limitations of the track, it could probably only be a limited service.

Can Capacity Be Increased If Needed?

Having lived near Cambridge for nearly thirty years of my life, I believe that there will come a time, when one four-car train between Norwich and Stansted Airport will not be enough.

  • Two tph could be run on the route, which is relatively lightly used by other services.
  • Longer trains could be created or two three-car trains could be run as a six-car train.
  • The current speed limit of 75-90 mph of the Breckland Line,  can probably be increased closer to the 100 mph of the Great Eastern Main Line.

Higher speeds would shorten journey times and increase capacity.

Could We See 125 mph Trains From Kings Cross To Kings Lynn And Norwich?

In Call For ETCS On King’s Lynn Route, I talked about putting digital signalling on the Kings Cross and Kings Lynn route and running 125 mph trains via Cambridge.

If the Kings Cross and Kings Lynn route were to be upgraded for faster running, this would also upgrade the proposed Kings Cross and Norwich route as far as Ely.

This would make it very feasible to run the following serrvices using 125 mph trains like Class 800 trains.

  • Kings Cross and Kings Lynn
  • Kings Cross and Norwich

Because of their speed these trains would help to open up capacity between Hitchin and Kings Cross.

I feel that these 125 mph bi-mode trains could do the trip between Kings Cross and Norwich in ninety minutes, which would match the time via Ipswich.

Do I Have Any Criticism?

My main criticism is that the service between Norwich and Stansted Airport, doesn’t have trains that run early and late enough.

Wil lthe service be timed to better fit the services out of the Airport?

Further Development Of The Breckland Line

This report in the Ely Standard from 2015, is entitled Could Railway Revolution See New Station Built at Ely North?.

These improvements are listed.

  • A new four-platform station North of Ely would improve connectivity.
  • A service between Kings Cross and Norwich via Cambridge is suggested.
  • Improvements in services across East Anglia.

A cost of a billion pounds is mentioned.

125 mph Trains From Kings Cross To Kings Lynn And Norwich

In Call For ETCS On King’s Lynn Route, I talked about putting digital signalling on the Kings Cross and Kings Lynn route and running 125 mph trains via Cambridge.

If the Kings Cross and Kings Lynn route were to be upgraded for faster running, this would also upgrade the proposed Kings Cross and Norwich route as far as Ely.

This would make it very feasible to run the following serrvices using 125 mph trains like five-car Class 800 trains.

  • Kings Cross and Kings Lynn
  • Kings Cross and Norwich

The two services could even split and join at the proposed Ely North station to make full use of the paths into Kings Cross.

The 125 mph or more operating speed of these trains on the East Coast Main line would help to increase capacity between Hitchin and Kings Cross.

I estimate that these 125 mph bi-mode trains could do the trip between Kings Cross and Norwich in ninety minutes, which would match the time via Ipswich.

Norwich could have the following services.

  • Three tph to and from London via Ipswich
  • Two tph to and from London via Cambridge
  • Two tph to and from Stansted Airport via Cambridge.

It sounds fantastic, but if we are to get travellers out of their cars, they must be given a high quality train service.

Conclusion

The improved Norwich and Stansted Airport service will be the first major improvement brought in by Greater Anglia.

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.

Oyster Card Scheme Extension Agreed

The title of this post is the same as that of this article on the BBC,

This paragraph describes the extensions.

Its extension, due in early 2019, will include Hertford North, Welwyn Garden City, Luton Airport Parkway and Epsom.

As the Oyster Card extension will also include intermediate stations, the following stations will be included on the four routes.

  • Hertford North – Crews Hill, Cuffley and Bayford.
  • Luton Airport Parkway – Radlett, St. Albans City and Harpenden
  • Welwyn Garden City – Potters Bar, Brookmans Park,Welham Green and Hatfield

All intermediate stations to Epsom are already in the Oyster Card Scheme.

Fourteen new stations will be added.

These are a few random thoughts.

Contactless And Oyster

Oyster card and most contactless payment methods with a card or mobile device can be used on Oyster Card reader, so in this post, I will use contactless to cover all methods.

I believe that in a few years, Oyster could be phased out, as cards and mobile devices will take over the ticketing.

Luton Airport Parkway

Adding Luton Airport Parkway station to the network, brings Luton Airport in line with Gatwick and Heathrow Airports.

This is very much a logical extension.

Airport Services

This is a list of the current times for airport services from London.

  • Gatwick – Express – 29 minutes – Thameslink – 39-60 minutes
  • Heathrow – Express – 15 minutes – Crossrail – 28 minutes
  • Luton – East Midlands Trains – 21 minutes – Thameslink 30-47 minutes
  • Southend – 52-53 minutes
  • Stansted – 49-52 minutes

If you look at the passenger statistics for Gatwick Airport station, they have been rising at around a million passengers a year for the past few years. How much of the recent rises have been due to the station going contactless in January 2016?

Certainly, if you’re late for a plane, contactless ticketing might save a couple of minutes.

I always remember an incident at Southend Airport station.

My plane was late and arrived very close to the departure time of the last train to London. There had recently been a lot of arrivals and the queues for tickets were long.

So a Greater Anglia employee took the decision to tell everybody to get on the train and we all went to London without tickets.

If ticketing had been contactless, Greater Anglia might have collected some fares.

But contactless at an airport is not solely about making money, but getting the passengers away from the airport quickly.

Hertford East And Hertford North Stations

Hertford East station accepts contactless cards.

Adding the facility to Hertford North station may open up some journey possibilities and ease ticketing.

The National Rail web site recommends that to go between Ware and Bayford stations on either side of Hertford, that you walk between the East and North stations.

An anytime ticket will cost you £19.50.

But buy two separate tickets between Ware and Hertford East stations and Hertford North and Bayford stations and it’ll cost £6!

Using contactless ticketing and touching in at all stations will save £13.50! Will this cost difference encourage more journeys with a walk in the middle?

When I visited the Hertford East Branch recently in mid-morning, I thought that it was surprisingly busy. Does lower-hassle contactless ticketing encourage more passengers?

Analysis of contactless touches will provide the answers to my two questions.

St. Albans City And St. Albans Abbey Stations

The Abbey Line between Watford Junction and St. Albans Abbey stations is not contactless, although Watford Junction station is so enabled and St. Albans City station will be.

There is surely a case for adding contactless ticketing to this short line of five intermediate stations.

Welwyn Garden City Station

Enabling Oyster on the route to Welwyn Garden City station, will mean that all stations on the Great Northern Route from Moorgate station will be enabled except for Watton-at-Stone  and Stevenage.

This would surely be less confusing for passengers, than the current arrangement, where Oyster tickeing is stopped at Hadley Wood and Gordon Hill stations.

Hopefully a suitable announcement would wake-up accidental fare avoiders at Hertford North station.

Epsom Station

The two routes to London from Epsom station are both fully Oyster-enabled, so surely adding one station to the routes shouldn’t be a difficult problem technically.

Further Routes For Oyster

Distances of the new Oyster-enabled stations, with a few existing ones, by rail from Central London are as follows.

  • Epsom – 16 miles from Victoria.
  • Gatwick Airport – 26 miles from Victoria
  • Hertford North – 20 miles from Moorgate
  • Luton Airport Parkway – 29 miles from St. Pancras
  • Shenfield – 20 miles from Liverpool Street
  • Welwyn Garden City – 20 miles from Kings Cross

So what other stations could be added?

Southend And Stansted Airports

Airports seem to like Oyster and as I said earlier, it can help to sort out ticketing problems at certain times.

  • Southend Airport station is 39 miles from Liverpool Street and there are five other stations between Southend Airport and Shenfield stations.
  • Stansted Airport station is 36 miles from Liverpool Street and there are six other stations between Southend Airport and Broxbourne stations.

This story on ITV is entitled Rail Minister Urged To Roll Out Oyster Card Payments To Stansted, Luton And Southend Airports.

Luton Airport will soon be Oyster-enabled, so hopefully Stansted and Southend Airports will be enabled soon.

Thirty Miles From London

There are a lot of places within thirty miles of London on commuter routes, that I’m sure eventually will be Oyster-enabled.

  • High Wycombe and Aylesbury – Chiltern have ambitions for this.
  • Rochester – 30 miles from London and on Thameslink.
  • Windsor

There will be other suggestions.

Extending Freedom Pass

I’d like to be able to just touch-in and touch-out to go to any station in the Oyster card area.

My Freedom Pass would be connected to a bank or credit card and I would be charged beyond the Freedom Pass area.

If Oyster cards can be linked to a bank or credit card, surely London’s control computer can be programmed to do something very powerful for Freedom Passes.

It could be a nice little earner for cash-strapped Transport for London.

Conclusion

Oyster is extending its reach and after this flurry of extensions in the next few months, lot of places will be wanting to be Oyster-enabled.

I suspect the only objector to this roll-out, will be the RMT, who have made the Luddites look like pussycats!

Why I Don’t Use Stansted Airport

There are two reasons, why I don’t use Stansted Airport.

Ryanair

There are better ways to fly!

Train Ticketing

It’s not simple and I can’t buy an extension ticket to my Freedom Pass as I can for Gatwick, Luton and Southend.

This picture sums it all up.

I’d use the Airport more if I could use a contactless card from Tottenham Hale station.

As an aside, I also think Cambridge should be in the contactless area.

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

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.

Northumberland Park Station – June 12th 2018

The new Northumberland Park station is coming on and has allowed the temporary footbridge to go somewhere else!

The level crossing will not be reinstated and I was wondering how pedestrians and others will cross the railway. There is still an old bridge on the other side to the station, but it doesn’t look to be in the best condition.

I then saw the two staircases in the new station.

So will there be two separate routes across the railway in one bridge?

This image from Network Rail, shows the station from the Eastern side.

There appears to be the following.

  • Two bridge sections, with the one on the far side connected to the low station buildings.
  • Two sets of stairs and a lift giving access from the bridge to the current Platform 1 and new platform behind it, that will become an island platform.
  • Two tracks this side of the island platform.
  • With the two tracks on the other side of the island platform, this means the station will be ready for four-tracking of the West Anglia Main Line.
  • A set of steps leading down from the near rend of the footbridge, this side of the extra tracks.

I have wondered for some time, when the West Anglia main Line is four-tracked and/or Crossrail 2 is built, which pair of tracks will be the fast lines.

In the interim it is obvious, that the third rack, which will run between  Meridian Water and Lea #bridge stations, will run on the near side of the island platform.

My only question is will it only handle trains towards Stratford or will the line be bi-directional?

But when the line is fully four-tracked, I think that the lines from West to East will be as follows.

  • Northbound Slow (Current Platform 2) – Local trains and Crossrail 2
  • Southbound Slow (Current Platform 1) – Local trains and Crossrail 2
  • Northbound Fast – Stansted and Cambridge services
  • Southbound Fast – Stansted and Cambridge services

I have put the slow lines on the West, as these are the platforms with the best access and few if any, fast services will stop in the station.

Crossrail 2 could of course change everything.

But I suspect that Northumberland Park station is being rebuilt, so that it will work with the most likely arrangement of tracks.

Walthamstow Central Tube Station To Receive £15m Improvement

The title of this post, is the same as that of this article in the Waltham Forest Guardian.

This is the first two paragraphs.

Walthamstow Central tube station has been allocated £15 million for improvements, but only if the controversial Walthamstow Mall redevelopment goes ahead.

New plans for the station include installing step-free access and a creating a new entrance.

That would surely get rid of the servere overcrowding that is experienced in Walthamstow Central station.

Overcrowding At Walthamstow Central Station

I often go to Walthamstow, at the tail end of the Evening Peak.

I have two routes.

  1. Take a bus to Highbury and Islington station and then use the Victoria Line.
  2. Take a bus to Hackney Downs station and then use the Chingford Line of the London Overground.

I always use the second route, as the two escalators at Walthamstow Central station can’t cope with the Victoria Line’s increased frequency of thirty-six trains per hour.

What makes matters worse is that all trains, except those going to and from the depot at Northumberland Park, run the whole length of the line between Brixton and Walthamstow Central stations.

Running this service on Dear Old Vicky, is one of the great engineering achievements on Metros around the world, but it means that passengers are finding some of the Victoria Line stations are inadequate. Walthamstow Central is one of them!

Another factor, that doesn’t help, is the excellent Walthamstow bus station. It is the third busiest in London and I’m sure it attracts more travellers to the rail and tube stations.

It is my belief, that the increase in train frequency and the building of the new bus station are the major cause of increasing overcrowding in the station.

It is worth noting that in 2016, the tube station handled nearly twenty-three million passengers with just two platforms and an up and a down escalator. By comparison, Cannon Street station, handled the same number of passengers with seven platforms and level access.

To be fair to Transport for London, they have sorted the gate lines at the station, but that still leaves the escalators severely overcrowded at times.

I actually can’t understand, why they haven’t replaced the middle staircase with a third escalator, as they have at Brixton, where there are also lifts.

Overcrowding Could Be Getting Worse!

Some transport improvements, that will happen in the next year or two,, will affect passenger numbers at Walthamstow Central station.

New Trains On The Chingford Line

The current Class 315 and Class 317 trains will be replaced by new Class 710 trains.

  • These will have the same number of carriages, but they will have a higher capacity, due to better design and being walk-through trains.
  • They will also have wi-fi and 4G available, if they follow the lead of the closely-related Class 345 trains.
  • Their operating speed has not been disclosed, but that of the Class 345 train is 90 mph, which is fifteen mph faster than a Class 315 train.
  • Their modern design will also allow them to save a minute or two at each of the seven stops.

The performance improvement may allow a more intense service.

The trains will certainly attract more passengers, as quality new trains always do!

  • Will the new trains generate more new passengers, than any forecaster dreamt was possible?
  • Will more passengers be attracted to stations North of Walthamstow Central and change to the Victoria Line?
  • Will some passengers change from using the Victoria Line to the Chingford Line?

Bear in mind, that new trains on the North London Line, started in 2010 with three-car trains running at six trains per hour (tph). They are now up to five-car trains running at eight tph. This is an capacity increase of over 120%.

On balance, I suspect that some of these factors will cancel each other out. But who knows?

New Trains On The Northern City Line

The geriatric Class 313 trains working the Northern City Line are being replaced by new Class 717 trains.

  • These new trains will offer higher frequencies and more capacity.
  • They will use 2+2 seating.
  • They will have wi-fi and power sockets.

Services on the Northern City Line have a cross-platform step-free interchange with the Victoria Line at Highbury & Islington station, so I believe the route will be increasingly used by passengers between the Walthamstow/Chingford area and the City of London.

Undoubtedly, it will increase passengers using the escalators at Walthamstow Central station.

New Trains On The Gospel Oak To Barking Line

The current two-car Class 172 trains on the Gospel Oak To Barking Line, are being replaced by four-car electric Class 710 trains.

  • The new trains will double capacity.
  • They will have better passenger facilities.
  • They will be more environmentally-friendly.

These trains could encourage travellers to use the quieter Walthamstow Queen’s Road station, instead of the very busy Walthamstow Central station.

Stratford To Meridian Water

This project will add a third track to the West Anglia Main Line and allow a four tph service between Stratford station and the new station at Meridian Water with stops at Lea Bridge, Tottenham Hale and Northumberland Park stations.

I have no view on how successful, this new line will be and how it will affect traffic on the Victoria line.

Crossrail

When you discuss transport provision in London, there is always a herd of elephants in the room!

Crossrail will change everybody’s journeys!

Crossrail will create a high-capacity fast route between Heathrow and Canary Wharf via Paddington, the West End and the City of London.

So how will those in Walthamstow and Chingford tie into this new high-capacity line?

In my view a direct link to Stratford is needed, which could be created by reinstating the Hall Farm Curve.

The World Ducking And Diving Championships

East Londoners would undoubtedly win the World Ducking-And-Diving Championships, if one were to be held.

Network Rail and Transport for London, are creating the ultimate training ground in North-East London.

Most people do a number of common journeys over time.

They get to know the best routes for these journeys dependent on various factors, like the time of day, weather and whether they are carrying heavy shopping.

For most people though, choosing the route for a particular day’s journey will not be process that can be written down, that might be more determined by random factors.

I for instance, will often choose my route, based on the first bus that comes along, even if it is not usually the quickest route.

To make journeys easier, through a network like North-East London, you need the following.

  • As many links as possible.
  • As few bottlenecks as possible.

These rules will allow the passengers to flow freely.

Passengers like water automatically find the quickest way from A to B.

Improvements In North-East London

There are various improvements in alphabetical order, that are proposed, planned or under construction for North-East London

Bicycle Routes Across The Lea Valley

The Lea Valley has a lot of green space and I have seen plans mentioned to create quiet cycling routes across the area.

It should also include lots of bikes for hire.

Hall Farm Curve

I mentioned this earlier and by building it to link Walthamstow and Stratford, it would enable direct access from Walthamstow and Chingford to the the following.

  • Olympic Park and Stadium.
  • The shops at Eastfield.
  • Crossrail
  • Docklands Light Railway
  • Jubilee and Central Lines
  • Highspeed serevices to Kent.
  • Continental services, if in the future, they stopped at Stratford.

It is a massive super-connector.

More Bus Routes

It may be that more bus routes or even stops are needed.

As an illustration of the latter, when the Walthamstow Wetlands opened, bus stops were provided.

New Stations

The new station at Meridian Water will add a new link to the transport network.

Two new stations on the Chingford Branch Line have also been proposed, which I wrote about them in New Stations On The Chingford Branch Line.

New stations are a good way to add more links in a transport network.

I shall be interested to see how many passengers the rebuilt Hackney Wick station attracts, when West Ham United are at home.

Northumberland Park Station

Northumberland Park station is being rebuilt with full step-free access, to provide better rail access to the new White Hart Lane Stadium.

Step-Free Access At Stations

Progress is being made, but there are still some truly dreadful access problems at some stations in East London.

Clapton, St. James Street, Seven Sisters, Stamford Hill and Wood Street certainly need improvement.

Tottenham Hale Station

Tottenham Hale Station is being rebuilt to give it full step-free access and a new entrance.

As this station handles well over ten million passengers a year, it is a good place to start.

Walthamstow Central Station

Walthamstow Central station is almost last in this alphabetical list.

It is probably, the second most important transport hub in North-East London and it does handle nearly thirty million passengers a year if the National Rail and Underground figures are combined.

But, is it treated last by the planners?

Walthamstow Wetlands

This massive urban nature reserve opened last year and its importance will only grow in the years to come.

Will transport links need to be added to the Wetlands?

West Anglia Main Line Four-Tracking

Stansted Airport will grow and to get proper rail access to the airport, the long promised four-tracking of the West Anglia Main Line will happen.

  • There will be two fast tracks for Cambridge, Stansted and possibly Norwich services.
  • There will be two slow tracks for local services up the Lea Valley to Broxbourne, Hertford East and Bishops Stortford.

Broxbourne station and the rebuilt Tottenham Hale station, will be the interchanges between fast and slow services.

Four-tracking will open up the possibility of lots more services up the Lea Valley.

There has been rumours, that Greater Anglia would like to open up a service between Stratford and Stansted. But that would be just for starters.

Liverpool Street station is full, but there is space at Stratford if the High Meads Loop under the shops and housing at Stratford is used, just like it was a few years ago.

The West Anglia Main Line could be turned into a high-capacity main line into London with two London terminal station; Liverpool Street and Stratford.

  • Both termini would be connected to Crossrail.
  • Liverpool Street connects to Central, Circle, Hammersmith and City and Metropolitan Lines.
  • The massive Liverpool Street-Moorgate Crossrail station will connect to the Northern and Northern City Lines.
  • Stratford connects to fast Kent services and Central and Jubilee Lines.

Will passengers for places like the West End get a fast train to Crossrail, rather than change for the Victoria Line at Tottenham Hale.

Conclusion

North-East London’s transport network is going to get better and better!

Note that I haven’t mentioned Crossrail 2! I doubt, this will be built before 2040!

Direct Trains Between Liverpool Lime Street And Norwich

In my wanderings around the UK, I very often come across this service and use it for short trips between two major towns or cities many miles from both Liverpool and Norwich.

The Current Service

Currently, the service is run by East Midlands Trains and is usually a two-car Class 158 train. Although, I have seen the service worked by a pair of these trains.

The route is very comprehensive with calls at Liverpool South Parkway, Widnes, Warrington Central, Manchester Oxford Road, Manchester Piccadilly, Stockport, Sheffield, Chesterfield, Alfreton, Ilkeston, Nottingham, Grantham, Peterborough, Ely and Thetford.

The service always seems to be full and I suspect that in addition to offering useful routes like Manchester-Sheffield, Liverpool-Nottingham and Nottingham-East Anglia, it is often a convenient route for some long distance business and family travellers.

The major problem for a train operator is that it needs a lot of rolling stock to provide a service.

Liverpool to Norwich takes five and a half hours, so to provide the hourly service probably needs as many as a dozen trains.

This extract comes from the East Midlands Trains section in Wikipedia entry for the Class 158 train.

The hourly Norwich to Liverpool service has been criticised for overcrowding, especially between Liverpool and Nottingham. This resulted from the Department for Transport specifying two-coach units in the EMT franchise starting in November 2007. In the light of persistent and excessive overcrowding, with some passengers being left behind on occasions, the DfT eventually admitted that it had made a mistake. Various cascades of other units enabled more Class 158 stock to be released for this route, and from the December 2011 timetable change the busiest services have been lengthened to four-coach trains between Liverpool and Nottingham, with units splitting and joining at Nottingham as necessary, two-coach trains being regarded as adequate between Nottingham and Norwich. Further services on this route were strengthened from December 2012.

Running a pair of Class 158 trains on the route between Liverpool and Nottingham, does seem to ease problems there, but I’ve encountered bad over-crowding at the Eastern end too.

Improvements On The Route

Several improvements or changes of rolling stock have or are taking place in the next few years.

Increased Capacity At Liverpool Lime Street

This is detailed in the 2017-2018 Station Remodelling section of the Wikipedia entry for Liverpool Lime Street station.

  • Two new platforms are being added.
  • Platforms are being lengthened.

In addition there are improvements on the approaches to the station.

Ordsall Chord And Related Improvements In Manchester

The Liverpool-Norwich service calls at both Manchester Oxford Road and Manchester Piccadilly stations, although it doesn’t use the new Ordsall Chord.

But I can’t believe that the Liverpool-Norwich service won’t be affected by all the works in Manchester.

Hope Valley Line Improvements

This article on Rail Technology Magazine is entitled Long-Awaited Hope Valley Line Plans Given The Green Light.

Improvements to the Hope Valley Line between Manchester and Sheffield include.

  • A loop to allow passenger trains to overtake slow freight trains.
  • Removal of a foot crossing.
  • Improvements around Dore and Totley station.

This is said on this document on the Transport for the North web site, which announces the Hope Valley improvements.

The new passing loops will mean three fast trains can run per hour between Sheffield and Manchester, one every 20 minutes, freight and stopping trains every hour, and a fast Manchester-Nottingham and East of England service every hour.

If nothing else, the extra capacity between Manchester and Sheffield, will reduce reliance on the Liverpool-Norwich service.

Improvements To The Midland Main Line

The Midland Main Line is not being electrified between Nottingham and Sheffield, but other improvements have taken place over the last few years.

  • In particular, the Erewash Valley Line has been improved and a new station at Ilkeston has been added.
  • The Liverpool-Norwich service calls at stations on this by-pass.
  • The line has been resignalled.

Would a train with a 125 mph capability, as opposed to the 90 mph operating speed of the Class 158 train, allow a faster service?

East Coast Main Line Running

The 90 mph Class 158 trains must present pathing problems on the East Coast Main Line, whereas a 125 mph train could mix it easier with the high speed trains.

Greater Anglia’s Plans

Greater Anglia have ordered a fleet of Class 755 trains.

  • The trains are bi-mode.
  • The trains have a 100 mph operating speed.
  • Greater Anglia have ordered fourteen three-car and twenty-four four-car trains.

Greater Anglia will be replacing 27 diesel trains, that consists of  58 carriages, with 38 bi-mode trains, that consist of 138 carriages.

  • There are forty percent more trains.
  • There are a hundred and thirty-eight percent more carriages.
  • Average train length of the diesels is 2.1 carriages, wheres that of the bi-modes is 3.6.

There are two possible reasons for these large number of trains.

  • Abellio have decided to buy a few bi-modes for their other franchises.
  • There is going to be a massive expansion of train services in East Anglia.

Two of the new bi-mode services interact with the Liverpool-Norwich service.

  • Colchester to Peterborough via Ipswich, Bury St. Edmunds and Ely
  • Norwich to Stansted Airport  via Ely and Cambridge.

Both services are thought to be hourly.

Consider the Colchester to Peterborough service.

  • I estimate that trains will take around two hours.
  • The round trip could be under five hours, even with a generous turn-round at both ends and perhaps a wait at Ipswich.
  • The waits would allow connecting passengers to join the train.
  • A five hour round trip would need five Class 755 trains.
  • I would choose four-car trains, as the route can get crowded.

Could the Colchester to Peterborough service be considered as an extension of the Liverpool-Norwich service, that serves Bury St. Edmunds, Ipswich and Colchester?

I think it could if the trains were timed appropriately.

  • Passengers from Liverpool to Ipswich, would change at Peterborough or Ely to the Peterborough to Colchester train, which would arrive a few minutes after the Liverpool to Norwich train.
  • Passengers from Ipswich to Liverpool, would change at Ely or Peterborough to the Liverpool train, which would arrive a few minutes after Colchester to Peterborough train.

Hopefully, the change would not require a platform change.

Consider the Norwich to Stansted Airport service.

  • I estimate trains will take about one hour and fifty minutes.
  • The round trip would be four hours and would need four Class 755 trains.
  • I would choose four-car trains, as the route can get crowded.

Could the Norwich to Stansted Airport service be equally spaced with the Liverpool-Norwich service between Ely and Norwich  to give a clock-face two trains per hour (tph)?

These services call at Ely

  • CrossCountry -Birmingham to Stansted Airport
  • East Midlands Trains – Liverpool to Norwich
  • Greater Anglia – Peterborough to Colchester
  • Greater Anglia – Norwich to Stansted Airport
  • Great Northern – Kings Lynn to Kings Cross

Totalling them up gives the following frequencies to various stations.

  • Bury St. Edmunds/Ipswich/Colchester – 1 tph
  • Cambridge North/Cambridge – 3 tph
  • Kings Lynn – 1 tph
  • Norwich – 2 tph
  • Peterborough – 3 tph
  • Stansted Airport – 2 tph

I suspect that the services will be arranged so there are convenient interchanges. No-one wants to spend an hour on a draughty Ely station waiting for the next train.

I also suspect that Greater Anglia  will use some of their extra trains to improve connectivity at Ely.

Speed Limits On The Route

Speed limits on the route are rather variable.

  • Liverpool to Manchester via Warrington is limited to 85 mph
  • The Hope Valley Line between Manchester and Sheffield is 90 mph
  • The proportion of the Midland Main Line, where 125 mph running is possible, is being increased.
  • Grantham to Peterborough on the East Coast Main Line allows 125 mph running.
  • The Peterborough to Ely Line is limited to 75 mph.
  • The Breckland Line between Ely and Norwich is limited to 75- 90 mph.

I feel that increasing speed limits on some parts of the line would help the Liverpool to Norwich service.

But surely, a train with a 125 mph-capability would help with journey times and train timetabling between Sheffield and Peterborough.

But on the rest of the route, trains with this speed capability, wouldn’t be needed.

Rolling Stock Choices For Liverpool Lime Street And Norwich

Various choices include.

Class 158 Trains

Everything could carry on as now using Class 158 trains

  • Two two-car trains working ass a pair would go from Liverpool Lime Street to Nottingham.
  • The trains would divide at Nottingham.
  • One train would go on its way to Norwich, and the other would wait at Nottingham to join with the train returning from Norwich.

With all the new diesel multiple units arriving in the next few years, I think it is likely that more Class 158 trains could be made available to strengthen the service.

The trouble with the Class 158 trains, is that with only a 90 mph operating speed, they can’t take advantage of the sections of the route where 125 mph running is possible.

Class 170 Trains

These trains were built as successors to the Class 158 trains.

  • They are more modern.
  • They are 10 mph faster.
  • Most  are three cars.

But they are still not fast enough for the 125 mph sections of the route.

A Second Service Between Liverpool And Nottingham

Improvements on the Hope Valley Line and in Liverpool and Manchester, might make it possible to run a much-needed second service between Liverpool and Nottingham via Manchester, Stockport and Sheffield..

This extra service could use the same trains as the full service.

Currently, the direct service between Liverpool Lime Street and Nottingham takes two hours thirty five minutes. In some ways, this is a problem, as if the timing was say two hours twenty minutes, a five hour round trip would be possible.

This would mean that the second service would need just five trains.

I doubt that Class 158 trains could meet this schedule, so more would be needed.

Class 800 Trains

Class 800 trains are 125 mph bi-mode trains, but are they fast enough on diesel to make real differences to the timetable by running fast on the Midland Main Line?

I think not!

So more trains would be needed to run the service.

Bombardier’s Proposed 125 mph Bi-Mode

A genuine 125-mph bi-mode, with that performance on both electricity and diesel, would be a totally different matter.

  • Timings between Liverpool and Nottingham would drop to perhaps two hours twenty, thus allowing a five hour round trip.
  • Timings between Liverpool and Norwich would drop to perhaps four hours fifty, thus allowing a ten hour round trip.

Even so a full service would require fifteen trains.

Bombardier have proposed a train of this type and I wrote about it in Bombardier Bi-Mode Aventra To Feature Battery Power.

In my view, this small exercise shows why some routes in the UK need a 125 mph bi-mode.

If the train can’t do 125 mph, where it is possible on the Midland and East Coast Main Line, the time savings on the route won’t be possible and more trains will be needed to run the service.

One great advantage is that the trains working this route could be the same as those working the main routes of the East Midlands franchise to and from London.

Short Formation InterCity 125 Trains

The forty-year-old InterCity 125 trains have the power and the speed to match the 125 mph bi-mode trains.

Short formation with four or five passenger cars between the two Class 43 locomotives are being used by Scotrail and Great Western Railway, but to use them on Liverpool to Norwich would require another fifteen trains to be updated, which is probably not as cost effective as new 125 mph bi-modes.

Conclusion

If service between the Liverpool Lime Street and Norwich is to continue in its present form, it needs 125 mph bi-more trains.

Harlow Council Leader Jon Clempner Hopes Crossrail 2 Will Extend To Town

The title of this post is the same as this article in Essex Live.

You might feel that Jon Clempner has a point, if you look at this diagram of the West Anglia Main Line between the M25 and Stansted Airport.

Note that Harlow Town station is only five and a half miles North of Crossrail 2’s proposed terminal of Broxbourne.

Greater Anglia’s New Trains

Greater Anglia are replacing ten twelve-car Class 379 trains on Cambridge and Stansted Airport services with ten twelve-car Class 745 trains.

You might ask why bother with this replacement, if the number of trains and carriages are the same, which initially will result in the same number of services.

I answer that question in  Why Are Greater Anglia Replacing Class 379 Trains With New Stadler Class 745 Trains?

But this doesn’t mean the current frequency is cast in stone, as the other fleet of Class 720 trains have a similar performance to the Class 745 and 755 trains, so they can mix it on the West Anglia Main Line.

I feel that all the trains would have these features.

  • Trains would be fitted with the latest signalling, so they could work with headways between trains as low as two or three minutes.
  • Trains will all be 100 mph trains or faster.
  • Trains would be designed to stop and restart at a station very quickly.
  • Trains could couple and decouple to make a longer train in a couple of minutes.

They will offer lots of opportunities to improve services.

The Current Service North Of Broxbourne

These current services stop at Broxbourne station in both directions..

  • One train per hour (tph) between Cambridge and London Liverpool Street – fast – stopping at Bishops Stortford and Hsrlow Town
  • One tph between Cambridge and London Liverpool Street – semi-fast – stopping at Stansted Mountfichet, Bishops Stortford, Sawbridgeworth, Harlow Mill, Harlow Town and Roydon
  • One tph between Stratford and Bishops Stortford – local stopping at Roydon, Harlow Town, Harlow Mill and Sawbridgeworth
  • One tph between Stratford and Bishops Stortford – local stopping at Harlow Town and Sawbridgeworth
  • Two tph between Hertford East and London Liverpool Street

In addition, there are four tph between Stansted Airport and London Liverpool Street (Stansted Express).

This means that the frequency of trains through various stations are as follows.

  • Broxbourne – 10 tph – Six stop (not Stansted Express)
  • Harlow Town – 8 tph – Four stop and some Stansted Express stop
  • Bishops Stortford – 8 tph – Two stop, two terminate and some Stansted Express stop.

So there is a maximum of ten tph or just one train every six minutes at Brombourne.

Given that Crossrail and Thameslink handle twenty-four tph through their central tunnels, eight tph is not very high!

Crossrail 2 At Broxbourne

Crossrail 2 will have its own dedicated tracks between London and Broxbourne and could be running twelve tph.

So if there were to be cross-platform interchange between the North of Broxbourne services and Crossrail 2, passengers could change between services as they needed.

The trains going North of Broxborne would be as follows.

  • 2 tph to Cambridge or Cambridge North
  • 2 tph to Bishops Stortford
  • 2 tph to Hertford East.
  • 4 tph to Stansted Airport

There would be a lot of scope to create an efficient service between all stations on the West Anglia Main Line and the two london termini of Liverpool Street and Stratford.

The Hertford East Branch

The Hertford East Branch isn’t a problem now, but the two tph between Liverpool Street and Hertford East station take up valuable paths on the lines to London.

The branch also has the following characteristics.

  • The platforms may not be long enough for ten-car Class 720 trains.
  • It is mainly double-track with a short length of single-track through Ware station.
  • It is fully electrified.
  • It is just seven miles long.
  • It might be possible to add a chord so that trains can access the branch from the Harlow direction from the West Anglian Main Line.

I suspect Network Rail and Greater Anglia have a plan with at least the following objectives.

  1. Keep a direct service between London Liverpool Street and Hertford East.
  2. Increase the frequency of trains to and from Hertford East to four tph.
  3. Avoid as much infrastructure work as possible.

Because of the new trains ability to couple and uncouple, I wonder if we could see two five-car Class 720 trains arrive at Broxbourne as a ten-car unit, with one train going to Hertford East and the other going to Bishops Stortford.

This would have the following advantages.

  • Hertford East gets four tph, including two new tph from Stratford.
  • Bishops Stortford get four tph, including two new tph from Liverpool Street,
  • Two tph could serve each of the London termini of Liverpool Street and Stratford.
  • The number of trains along the West Anglia Main Line between Tottenham Hale and Broxbourne is unchanged.
  • Hsrlow Town and Sawbridgworth  get another two tph to Liverpool Street.

I’m probably wrong, but there will be a better idea somewhere.

Conclusion

Crossrail 2 doesn’t need to go to Harlow Town, but Greater Anglia’s new trains should give a better service.

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.
