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.

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 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.

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.

Could Enfield Lock Station Have A Bay Platform?

In West Anglia Route Improvement – Modern Railways March 2017, I mentioned that Crossrail 2 might like to have turnback platform at Enfield Lock station.

As this morning, I turned back myself at Enfield Lock station, as it’s the Freedom Pass limit, I took these pictures.

This Google Map shows the middle of the station.

If you look at the West side of the station by the Down line, you’ll notice the house, which from the pictures could be a candidate for demolition.

So I do think, it might be possible to squeeze an extra platform, by the Down Line.

This Google Map shows the Southern end of the platforms.

The space available would certainly be enough for an extra platform, but will there be enough for two fast lines between the current Up Line and the houses?

I suspect that there is, if the current lines could be moved slightly to the West.

But as at Tottenham  Hale and Brimsdown, fitting the two fast lines through \Enfield Lock, is going to need a cunning plan.
