The Anonymous Widower

Crossrail 2 And The Chingford Branch Line

The Chingford Branch Line will be effected both during construction and after opening by Crossrail 2..

In Rumours Of Curves In Walthamstow, I said this.

But with the design stage of Crossrail 2 well underway, I do wonder, if connecting Chingford station and the related sidings to the West Anglia Main Line, might give Crossrail 2 better options to build the line or provide alternative services, whilst the West Anglia Main Line is rebuilt through the area.

I still think that the Chingford Branch Line will be an invaluable resource to help get the Northern end of Crossrail 2 built.

If the Coppermill Curve is built in the near future, I feel the main reason will be to help build Crossrail 2 and rebuild the West Anglia Main Line to four-tracks.

Once Crossrail 2 is open, I think that the two lines will be connected together at Seven Sisters/South Tottenham. There is a lot of scope for a major passenger-friendly interchange and as it will be a few years after Crossrail, the design will draw on the experience of theearlier line.

Conclusion

The Chingford Branch Line will end up being tightly linked to Crossrail 2.

Could Reversing Sidings Be Used On The Chingford Branch Line?

In Improving The Chingford Branch Line, I showed how the new Class 710 trains and some adjustment to timetables could run eight trains per hour (tph) to Chingford, with 4 tph each going to Liverpool Street and Stratford, by getting the trains to cross at the level crossing at ighams Park station.

Several stations in London, including some on the Underground, have what is known as reversing sidings. In How Trains Reverse At West Croydon, I described the working of the reversing siding there, which London Overground trains use to swap tracks to get back to Dalston Junction station.

So could a strategically placed reversing siding be placed to turn back some services, before the Highams Park level crossing?

I don’t think a reversing siding would be needed until the Coppermill Curve was reinstated to allow trains to go to and from Tottenham Hale to Walthamstow, And even then, it would only be needed if more than eight tph were running to Walthamstow.

A reversing siding would allow the following.

  • More than eight tph to go to Walthamstow.
  • The creation of a triangular service from Tottenham Hale to Lea Bridge via Walthamstow.
  • Services between Chingford/Walthamstow and Seven Sisters/South Tottenham for a future Crossrail 2.
  • Services between Chingford/Walthamstow and Gospel Oak along the Gospel Oak to Barkjing Line.

This map from carto.metro.free.fr shows the railway lines around Seven Sisters station.

There are certainly a lot of possibilities.

  • The Seven Sisters Chord gives access to Seven Sisters, Enfield Town and Cheshunt.
  • The Gospel Oak to Barking Line gives access to Cricklewood, Gospel Oak, Richmond and West Hampstead.
  • The Gospel Oak to Barking Line gives access via Cricklewood to the Dudding Hill Line for Acton..
  • The Gospel Oak to Barking Line gives access via |Willesden Junction to the West London Line for Clapham Junction.

If another four tph service is created to Walthamstow, I suuspect it will be a third long East-West service, which will give eight tph on the busy part of the Gospel Oak to Barkling Line west of South Tottenham.

There are only three stations or four if you add in Forest Road, which I talked about in New Stations On The Chingford Branch Line.

  • St. James Street
  • Walthamstow Central
  • Wood Street
  • Forest Road.

I’ll look at each in detail.

St. James Street Station

This is probably too difficult and it’s the first station.

Walthamstow Central Station

This Google Map shows the station.

Walthamstow Central Station

Walthamstow Central Station

I think it could be a possibility.

I think that the platforms are certainly able to accept eight car trains and might even take twelve, so there should be space for a reversing siding between the two lines to the East of the station.

Wood Street Station

This Google Map shows the station.

Wood Street Station

Wood Street Station

Again, I think this is a possibility.

Wood Street station will need a lot of rebuilding to make it step-free and there is space beyond the platforms towards Chingford to put in a reversing siding for a train.

These pictures show the station.

It is a station with potential.

Forest Road Station

This Google Map shows where Forest Road station will probably go.

It could be just too restricted a site.

How Would The Trains Be Organised?

I think that Walthamstow Central or Wood Street will be the station with a reversing siding.

Say there are going to be three 4 tph services. They could be.

  • Gospel Oak to Walthamstow Central or Wood Street
  • Liverpool Street to Chingford
  • Stratford to Chingford

The sequence at the reversing station would be.

  1. The train from Gospel Oak arrives in the down platform, discharges passengers and goes into the reversing siding.
  2. The two Chingford services arrive in the down platform, one after the other, pick up any passengers and go to Chingford.
  3. The two Chingford services arrive in the up platform, one after the other, pick up any passengers and go to Stratford and Liverpool Street.
  4. The train for Gospel Oak comes out of the reversing siding into the up platform, picks up passengers and goes on to Gospel Oak.

No passengers would have to change platforms to change trains.

Would It Be Sensible To Have A Reversing Siding Anyway?

I’m no expert, but I think the answer is Yes!

Crossrail have a reversing siding at Chadwell Heath station, that they say is for service recovery, in this page on their web site.

So perhaps, if say there was a problem on the highams Park level crossing, a train or two could be diverted to the reversing platform to await their slot on the return from Chingford.

Conclusion

A reversing siding at either Walthamstow Central or Wood Street would allow extra services to be developed around the Coppermill Curve and also be useful for service recovery.

New Stations On The Chingford Branch Line

I have pulled this post out of What Might Have Been At Walthamstow And Woodford, as I want to have a series of linked posts that described the various ways that the Chingford Branch Line could be improved.

In the Future Developments section of the Wikipedia entry for the Chingford Branch, it is said that there may be a station at both Forest Road and Chingford Hatch, either side of Highams Park station.

This map shows the area.

The red arrow indicates Chingford Hatch, with the two stations shown being Highams Park in the middle and Wood Street at the bottom.

Chingford Hatch Station

This Google Map shows the location of Chingford Hatch between Highams Park and Chingford stations.

Chingford Hatch

Chingford Hatch

Chingford station is at the top and Highams Park station is st the bottom.

I suspect if the station is built, it will be somewhere near the roundabout. The railway is a short distance to the East.

As the railway appears to be on a bridge, it won’t be a simple station to build.

Forest Road Station

This Google Map shows the probable location of a new station on Forest Road in Walthamstow.

The station would probably be built where Forest Road crosses the railway line.

I suspect that if the station was built, it would be a simple affair with platforms on either side of the current line.

At present there is no more information on either station.

Walthamstow Village Station

This Google Map shows the up-and-coming area of Walthamstow Village.

The railway is in a deep cutting and I suspect despite what the locals might think a station wouldn’t be practical.

But I suspect, there would be space for a reversing siding, that could be used by trains reversing at Walthamstow Central station.

Conclusion

Both proposals look sound, but passenger statistics will define if new stations are built.

Improving The Chingford Branch Line

The Chingford Branch Line has a four trains per hour (tph) service between Liverpool Street and Chingford via Hackney Downs and Walthamstow Central stations.

Those that I know who live in the area, have a few simple wishes.

  • New trains with wi-fi and other passenger-friendly features.
  • More trains to improve services and take the pressure off the Victoria Line.
  • A service from Chingford and Walthamstow to Stratford and Crossrail.
  • Perhaps some new stations.
  • Step-free access at St. James Street and Wood Street stations.

The following sections tackle these wishes in more detail.

New Class 710 Trains

The biggest change to the line will come with the new Class 710 trains in a couple of years time.

Thirty new four-car Class 710 trains will replace the same number of Class 315 and Class 317 trains, that currently work the  Cheshunt and Chingford services.

  • As the number of trains and their length is the same, the service frequency and capacity will be no worse than at present.
  • The trains will be modern and have air-conditioning and all the features that passengers now expect.
  • The trains will be fitted with various driver aids to ensure accurate timekeepers.
  • Nothing has been said about wi-fi, but most other new Aventras will have free wi-fi fitted, so I suspect it will be fitted or there will be a big argument.
  • I am of the belief that all Class 710 trains will be fitted with enough onboard energy storage to handle regenerative braking and short movements not connected to the overhead wires.
  • Onboard energy storage would also mean the trains could be fitted with remote wake-up, so that trains stabled overnight at Chingford, can be driver and passenger ready before the driver arrives to start the service in the morning.

It should be noted that London Overground has taken an option for another twenty-four trains. So could some of these trains be added to the fleet on the Chingford Branch to increase capacity and service on the Branch?

The Highams Park Level Crossing

In an ideal world, more services would be provided on the Chingford Branch to Liverpool Street for the following reasons.

  • The Victoria Line from Walthamstow Central now has the trains to handle passengers to Central London, but the station doesn’t have the capacity to handle them, due to its cheapskate 1960s design.
  • The Chingford Branch has direct access to Crossrail at Liverpool Street whereas the Victoria Line doesn’t connect to London’s new train line.
  • The Chingford Branch has direct access to the North London Line at Hackney Downs and the new Class 710 trains, will mean that North London Line services will be increased.
  • Crossrail could release extra platform space at Liverpool Street for  more London Overground services.

But there is one major problem to increased services on the current Chingford Branch. They must all go through the level crossing at Highams Park Station.

  • There is only long detours, if the crossing is closed.
  • Extra trains would cause significant traffic congestion.
  • Extra trains would mean the crossing would be closed for a large proportion of every hour.

As it is unlikely that the money could be found for a bridge or tunnel at Highams Park, the only thing that can be done, is make sure that all train services be at maximum length, which is probably eight cars.

Obviously, longer trains would help, but in the long term, I’m certain that London Overground would want to run more frequent services between Liverpool Street and Chingford.

I think it is true to say that the train frequency of the Chingford Branch through Highams Park is probably limited by a maximum of eight closures per hour of the Highams Park level crossing, unless the level crossing could be closed or by-passed.

But is maximum use being made of the level crossing closures now?

At present in the Off Peak.

  • Trains arrive at Highams Park from Chingford at 14, 29, 44 and 59 minutes past the hour.
  • Trains leave Highams Park for Chingford at 08, 23, 38 and 53 minutes past the hour.

I don’t think that this means that a Northbound and a Southbound train can share a single closure of the level crossing. This page on the National Rail web site, shows live departures at Highams Park.

If they could, then that would cut the number of times the crossing closed in the Off Peak by half.

Things that will help, is that the Class 710 trains will have extensive driver aids and probably onboard signalling, so the precise timekeeping that would be required, so two trains shared a level crossing closure, could be a lot easier.

Eight trains per hour in the Off Peak in both direction through Highams Park station is a distinct possibility.

This 8 tph frequency could be continued through the Peak, as it’s probably better than the current timetable.

Eight Trains Per Hour From St. James Street To Chingford

So it looks like that modern Class 710 trains running to a precise timetable could mitigate the problems of the Highams Park Level Crossing and allow eight trains per hour between St. James Street and Chingford.

|As there is no other trains using the branch, except moving empty and some engineering trains to and from the sidings at Chingford, there is probably little to interfere with an 8 tph schedule.

South From St. James Street

South from St. James Street station, the trains go through the Coppermill Junction area and cross the West Anglia Main Line.

The Chingford Branch then joins the line from Tottenham Hale to Hackney Downs, as this map from carto.metro.free.fr shows.

 

Coppermill Junction

Coppermill Junction

The map shows Coppermill Junction, where the Chingford Branch Line crosses the West Anglia Main Line, that runs North from Liverpool Street to Tottenham Hale, Bishops Stortford, Stansted Airport and Cambridge.

I suspect that there would be a problem fitting another four tph through Hackney Downs station and on to Liverpool Street.

In Rumours Of Curves In Walthamstow, I talked about how two curves would be rebuilt, based on information from an informant with detailed knowledge.

  • The Hall Farm Curve would be rebuilt as a bi-directional single-track connection between St. James and Lea Bridge stations.
  • The Coppermill Curve would be rebuilt to give a connection between St. James and Tottenham Hale stations.

The Hall Farm Curve is the significant one for passenger services on the Chingford Branch Line, as it would mean that the current service of 4 tph between Chingford and Liverpool Street would be augmented by a second 4 tph between Chingford and Stratford.

  • Waltham Forest would get an 8 tph metro service between St. James and Chingford stations.
  • There are extensive bus connections at Chingford, Walthamstow Central and Stratford.
  • The line has good connections to the Victoria Line, the Jubilee Line, the Central Line and Crossrail.

The only infrastructure needed would be the single-track Hall Farm Curve. If the Class 710 trains were to be fitted with onboard energy storage, this curve would not even need to be electrified.

Conclusion

By using the  features of the new Class 710 trains, Chingford can be given four trains per hour to Liverpool Street and 4 trains per hour to Stratford, if a new single-track Hall Farm Curve without electrification is built between St. James and Lea Bridge stations.
