The New Bridge At Tottenham Hale Station – 22nd November 2018

The new footbridge at Tottenham Hale station is being constructed.

It looks like the station should be finished by the middle of next year.

Tottenham Hale Station – 1st October 2018

These pictures show the progress being made at Tottenham Hale station.

Note.

  1. The third platform at Tottenham Hale station is taking shape.
  2. The steelwork is up for the lift towers.
  3. A lot of the third track and the electrification is in place.

I am also coming to a couple of conclusions.

  • There appears to be enough space alongside the third track to insert a fourth.
  • The Ferry Lane road bridge though may need to be rebuilt to get the fourth track through.

Progess also appears to be in-line with completion of the station and the third track before the end of 2019.

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

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

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

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

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

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

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

There has been steady and worthwhile progess since.

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

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

Use Of The Third Track

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

The Northern End

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

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

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

Meridian Water Station

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

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

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

The dotted line on the map is the third track.

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

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

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

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

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

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

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

Using The Third Platform At Tottenham Hale Station

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

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

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

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

The following journey times should be noted.

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

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

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

The Southern End

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

Is The Third Track Going To Be Bi-Directional?

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

What Will Be The Operating Speed Of The Third Track?

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

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

Everything certainly looks professional to my untrained eye.

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

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

Could The Third Track Be Extended Northwards?

The length of the third track is 5.5 km.

Could the third track be extended to the North?

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

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

These are my observations

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

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

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

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

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

Currently, How Many Calls Are There At Each Station?

These figures are calculated from the current timetable.

Lea Bridge

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

Two tph stop in both platforms.

Tottenham Hale

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

  • Two tph – Liverpool Street to Stansted
  • Two tph – Stratford to Bishop’s Stortford

Four tph stop in both platforms.

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.

Tottenham Hale Station – 30th April 2018

These pictures show the space to the East of the third platform space, where the third track will go through.

It looks like there isn’t much space for the fourth track, if they want to squeeze one in. Or will the piles for the electrification have to be moved?

West Anglia Route Improvement – STAR – 5th March 2018

These are some pictures I’ve taken and observations I’ve made in recent days.

An Unusual Train Movement At Stratford

I took some of the pictures for this post from a Stratford to Bishops Stortford train.

Whilst waiting in Platform 11 at Stratford, a Class 321 train, ran past my train and through Platform 12.

It could have just been an empty stock movement from Orient Way Sidings to Liverpool Street.

Or was it going round the High Meads Loop, possibly for driver training?

From Lea Bridge Station To South Of The Chingford Branch

Work has been progressing on this section, as these pictures show.

Track is starting to be laid, but there is no evidence of the points, where the three tracks will merge into two.

From North Of The Chingford Branch To Tottenham Hale Station

Work has been progressing here too!

The Space Towards Chingford

This Google Map shows Coppermill Junction.

Note there is a lot of space on the Chingford side of the junction.

Could Network Rail be reinstating the Coppermill and Hall Farm Chords? Or at least creating the space to do it? I wrote about these chords in Rumours Of Curves In Walthamstow.

Nothing has been published or said, but there’s an awful lot of work going on to just add a third-track between Meridian Water and Lea Bridge stations.

The Island Platform At Tottenham Hale Station

An island platform is emerging at Tottenham Hale station.

The current platforms are as follows.

  • 1 – Southbound to Liverpool Street and Stratford
  • 2 – Northbound to Bishops Stortford,Cambridge,  Hertford East and Stansted Airport.

This map from carto.metro.free.fr shows the new layout.

Blue is the Victoria Line.

So it looks like an extra Platform 0 is to be added on the new track, which will be an island platform with Platform 1.

These pictures show the current works.

It looks to me, that there is a surprising amount of space and it might be possible to squeeze two tracks in the space.

Conclusion

Work is certainly progressing.

New Bridge In Tottenham Marks The Beginning Of Restoring A Line Lost During The Beeching Era

The title of this post says it all and is the same as this article on Rail Professional.

Some might argue that Beeching got it wrong!

My feelings though are the politicians and British Rail managers of the day  generally didn’t have any vision about how the railways should be simplified to on the one hand save money and on the other perhaps create paths, cycleways and leisure facilities, for the good of everyone.

Harold Wilson’s view that everybody would have their own car and the railways were finished didn’t help either.

The Lea Valley was my childhood playground and I’d regularly cycle to the area. But unlike now, much was closed to the public.

This Google Map shows the location of the bridge.

Note.

  1. The railway line is the West Anglia Mail Line, running South from Tottenham Hale stations.
  2. The bridge carrying the Easter pair of tracks is being replaced.
  3. Tottenham South Junction is North of the bridge and the line going West is the Tottenham South Curve, that links the West Anglia Main Line to the Gospel Oak to Barking Line.
  4. The Markfield Beam Engine is to the West.
  5. The Walthamstow Wetlands are to the East.

The area will get even more complicated in the future, when Crossrail 2 is built.

These are various pictures of the bridge site, taken on different dates

The bridge will be an important link in the development of the railways in the area.

Is It Possible To Squeeze Two New Tracks Through Tottenham Hale Station?

Now that the area behind the station is more or less cleared and the signalling cables seem to have been rerouted, you can get a better idea.

Will the new tracks be the Slow or Fast Lines?

As the third track is being installed for STAR at the present time, it would appear that the two new lines will be the Slow Lines.

Transport for London Warns Crossrail 2 Could Be Delayed By Decade

The title of this post is the same as that of an article in the Financial Times.

It’s all about funding and probably the Government not wanting to finance all of the large rail projects.

  • HS2
  • Crossrail 2
  • Northern Powerhouse Rail
  • East West Rail

HS2 is funded and underway and the last two projects are being sorted, but the cost of Crossrail 2 is too much to digest.

I have believed for some time, that Crossrail 2 is a number of separate projects.

  • Increasing capacity on the Waterloo suburban lines
  • Increasing capacity on the Lea Valley Lines
  • Creation of the mega-station at Euston-St. Pancras
  • New trains
  • The high capacity central tunnel

I will now look at each in detail.

Increasing Capacity On The Waterloo Suburban Lines

In An Analysis Of Waterloo Suburban Services Proposed To Move To Crossrail 2, I showed that it would be possible to run a service with Crossrail 2’s characteristics terminating in Waterloo.

I said the following were needed.

  • More platform capacity in Waterloo.
  • Modern high-performance 100 mph trains like Class 707 trains or Aventras.
  • Some improvements to track and signals between Waterloo and Wimbledon stations.
  • Wimbledon station would only need minor modifications.
  • A measure of ATO between Waterloo and Wimbledon stations.

Much of the infrastructure works have been completed as I reported in It’s All Over Now, Waterloo!.

All it needs is Bombardier to build the new Class 701 trains for South Western Railway.

Increasing Capacity On The Lea Valley Lines

In Could A Lea Valley Metro Be Created?, I looked at the possibility of creating a Lea Valley Metro with the following characteristics.

  • Four-tracks between Tottenham Hale and Broxbourne stations.
  • Step-free stations.
  • Termination in the unused loop at Stratford.
  • 10-15 trains per hour.
  • Links to Crossrail, the Underground and Southeastern Highspeed services at Stratford.

I came to the conclusion it was very much possible.

Creation Of The Mega-Station At Euston-St. Pancras

In Should A Mega-Station Be Created At Kings Cross-St. Pancras-Euston?, I looked at this mega station project for Crossrail 2.

I came to these conclusions.

  • If Crossrail 2 is built, there will obviously be a mega station at Euston St. Pancras.
  • But I believe that all the other improvements that will happen before HS2 opens may well be enough to cope with the extra capacity needed.
  • Obviously though, any improvements must not compromise the building of Crossrail’s mega-station.

In Should A Mega-Station Be Created At Kings Cross-St. Pancras-Euston?, I proposed a four-level mega-station.

  • Surface level – National Rail and HS2
  • Sub-surface level – Circle, Hammersmith and City and Metropolitan Lines
  • Deep level – Northern, Piccadilly and Victoria Lines.
  • Very deep level – Crossrail 2

Lines would be connected by escalators, travelators and lifts going all over the place.

It would not be that different to the double-ended Crossrail station at Moorgate-Liverpool Street station, which I described in London’s First Underground Roller Coaster, except that it connects three stations instead of two.

This would enable Crossrail 2 to be bored through at a deeper level after Euston station had been rebuilt for HS2.

In terms of Crossrail 2, the creation of the mega station at Euston St. Pancras could be the last project to be completed.

New Trains

This should be the easy bit, as surely using the same Class 345 trains on Crossrail and Crossrail 2, would be an objective, if it were possible.

The High Capacity Central Tunnel

I’ve never built a tunnel, although my software; Artemis helped to build the Channel Tunnel, but I would suspect that building the central tunnel for Crossrail 2 will be easier than building that for Crossrail.

So many things like riding a bike or sex are a lot easier the second time.

There must be so many lessons from Crossrail that can be applied to Crossrail 2.

If all of the central stations on the tunnel, from Dalston to Wimbledon, where there is interchange with Crossrail 2 can be made tunnel-ready, then I don’t see why boring the central tunnel can’t be one of the last jobs to be started.

The tunnel boring machines would then just pass through the stations to link them all together.

It’s probably not as simple as that, but it is going to be a lot easier job than Crossrail.

The Importance Of The Victoria Line

I’ve never seen this said before, but one of the keys to building Crossrail 2 is the Victoria Line or Dear Old Vicky.

I believe the Victoria Line should be updated as follows to be as near the standard of Crossrail as possible, by using the existing trains, track and signalling  and by updating the stations.

  • Addition of the missing escalators and other features left out to save money in the 1960s..
  • Full step-free access at all stations.
  • Addition of new  entrances at Oxford Circus, Highbury and Islington and Walthamstow Central.
  • Better interchange with the Overground at Blackhorse Road and Walthamstow Central.
  • Better interchange with National Rail at Brixton, Vauxhall, Finsbury Park, Seven Sisters and Tottengham Hale.
  • Forty tph between Brixton and Walthamstow Central.

Forty tph may need a reversing loop at Brixton and an extra one-platform station at Herne Hill.

I believe that an update of this type and scale could be applied to the Victoria Line without causing too much grief for passengers. The work on the stations is necessary to cope with the current and increased passenger numbers and could be carried out in much the same way as the upgrade at Victoria station has been done in the last few years.

The Victoria Line would then offer a high capacity link between Tottenham Hale and Vauxhall prior to the building of Crossrail 2’s central tunnel.

Passengers from say Broxbourne to Hampton Court would take the following route.

  • Lea Valley Line from Broxbourne to Tottenham Hale – (10 tph)
  • Victoria Line from Tottenham Hale to Vauxhall – (>30 tph)
  • South Western Railway from Vauxhall to Hampton Court – (4 tph)

Two changes (both hopefully step-free) would be needed, but with improvement to the National Rail routes at both ends, it would be faster than now.

The Importance Of The Bakerloo Line

Ask TfL’s Journey Planner, which is the quickest way from Tottenham Hale to Waterloo and it gives the following route.

  • Victoria Line from Tottenham Hale to Oxford Circus
  • Bakerloo Line from Oxford Circus to Waterloo

There is a simple cross-platform interchange at Oxford Circus, with the two legs taking 16 and 8 minutes respectively.

Currently, the Bakerloo Line has a frequency of twenty-two tph and plans have been mooted, that will see this going to twenty-seven tph by 2033.

It looks like when combining an updated Victoria Line with the current Bakerloo Line, you get a excellent connection that can stand-in for the Crossrail 2 central tunnel between Tottenham Hale and Waterloo.

But the Bakerloo Line might be extended to Lewisham, so will this extension make the combined Victoria/Bakerloo route more important.

The extended Bakerloo Line is not planned to have a connection with Crossrail 2, so using the Victoria Line across Central London will probably be the fastest way from say Lewisham to Enfield Lock.

It looks to me, that the cross-platform interchange at Oxford Circus between the Bakerloo and Victoria Lines is more important than anybody thinks and will continue to be so.

The Splitting Of The Northern Line

TfL would like to split the Northern Line into two branches, but this can’t be done until Camden Town station is rebuilt around 2024.

The only effect this split will have on Crossrail 2, is it will give extra routes to Euston station, which may probably make it less important that Crossrail 2 is completed before HS2.

A Possible Timetable

This is very much speculation on my part.

  • 2020 – Improved Overground services to Cheshunt, Chingford and Enfield Town using new Class 710 trains.
  • 2021 – Increased Greater Anglia services on the Lea Valley Lines using new Class 720 trains.
  • 2021 – Waterloo suburban branches running at four tph using new Class 701 trains.
  • 2024 – Extended Camden Town station opens.
  • 2024 – Splitting of the Northern Line
  • 2024 – More capacity on the Victoria Line
  • 2025  – Increased services on the Lea Valley Line after four-tracking.
  • 2025 – Upgraded Euston station opens with better connection to the Underground.
  • 2026 – Old Oak Common statio opens
  • 2026 – HS2 opens to Birmingham

The Crossrail 2 central tunnel could be built, when traffic levels are predicted to be too much for the Victoria Line.

Conclusion

This analysis says to me that Crossrail 2 could be planned as a series of much smaller projects, that would give passengers benefits from the early-2020s and also ease the funding problems for the line.

But the analysis also says that if the central tunnel is not built before the 2040s, then the Victoria Line must be upgraded to create a high capacity link between Tottenham Hale and Vauxhall or Waterloo using the Bakerloo Line.

Extra Track Up The Lea Valley

Yesterday, Network Rail released this document on their web site, which is entitled Extra track to be installed in Lee Valley this autumn for a bigger and better railway.

This is the opening sentence.

Work to build a new track between Stratford and Angel Road is being stepped up this autumn as part of the £170m Lee Valley Rail Programme to increase services and boost local regeneration.

Network Rail will carry out the following work as part of its Railway Upgrade Plan:

  • Strengthening the River Lea rail bridge near Tottenham Hale to support the new third track
  • Installing foundations for the new overhead line structures to provide power for trains using the third track
  • Installing foundations for the new island platform and footbridge at Tottenham Hale station to help people move around the station easier
  • Installing foundations for a new island platform at Northumberland Park to allow access to trains that will use the new track
  • To make the most of the closure, track will also be renewed near Lea Bridge station as part of the track renewals programme

It certainly makes my pictures clearer.

I took these pictures yesterday.

Note.

  1. The current platform 1 at Tottenham Hale station will be turned into an island platform.
  2. It will be tight to squeeze everything in at Tottenham Hale.
  3. It looks like the space for the track between Tottenham Hale and Angel Road stations has been cleared.
  4. The current platform 1 at Northumberland Park station will be turned into an island platform.
  5. The level crossing at Northumberland Park station has been closed.

It would appear a good start has been made.

This Google Map shows the footbridge that goes over the tracks and the Victoria Line Depot.

Note that when it comes to squeezing in a fourth track, there is more space than first appears.

From Tottenham Hale To Northumberland Park

I wanted to see if I could see any more of the works to create STAR, so I walked between Tottenham Hale and Northumberland Park stations.

I first crossed the railway on the road bridge and then used a footbridge to cross back again.

The Google Map show the area.

Note.

  • The footbridge crosses the road and the various railway lines at the top of the map. The blue dot at its Eastern End is a bus stop.
  • STAR will run on the Eastern side of the railway, in the space, which looks green on this map.
  • Northumberland Park is the next station to the North
  • Tottenham Hale is the next station to the South.

The map shows it is a tight space to thread a railway.
