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.

West Anglia Route Improvement – Timings Between Tottenham Hale And Broxbourne Stations

How long do various trains take between Tottenham Hale and Broxbourne stations?

The Line

The distance between the two stations is 11.2 miles or 18 kilometres and there are the following stations.

The stations marked with an asterisk (*) have level crossings.

The line has an operating speed of 100 mph in places, but a lot of places are much slower.

Slow Services

The slowest service takes twenty minutes  stopping at all stations except for Northumberland Park and Angel Road stations.

Fast Services

The fastest service takes thirteen minutes with just a stop at Cheshunt, which gives an average speed of about 52 mph.

Fast Services Using A Dedicated Line

If a dedicated line between Tottenham Hale and Broxbourne were to be built where trains perhaps only stopped at Broxbourne, averaging 80 mph would mean a time of 8.4 minutes.

So there is potential if the dedicated fast line were to be built as a 100 mph line and trains ran non-stop to make savings of several minutes.

Slow Services Stopping At All Stations With Modern Trains

Crossrail is replacing elderly Class 315 trains with new Class 345 trains and it might be worth looking at these times for between Goodmayes and Brentwood stations, where there are four stops.

  • Class 315 train – 21 minutes
  • Class 345 train – 15 minutes

Greater Anglia are swapping elderly Class 317 trains with new Aventras, which are designed for quick stops, as are Crossrail’s Class 345 trains.

So I suspect that if a minute is saved for each stop, that would mean with the same stopping pattern, a time of 15 minutes could be possible.

I just wonder, if with a few tweaks, that trains can could match the current fastest time of thirteen minutes stopping at everywhere except for Northumberland Park and Angel Road stations.

Consider.

  • All stations will be made step-free, so once passengers learn the ropes, loading and unloading delays will be minimised.
  • Platforms will be aligned to the trains for fast loading and unloading.
  • STAR will handle Angel Road and Northumberland Park stations.
  • Four level crossings will be closed, which must help.
  • Both types of trains on the route would have similar performance and they would just run slower for slow services.
  • Fast trains will have their own line.
  • Help from the signalling and Driver Assistance Systems.

In addition, we mustn’t underestimate the contribution driver skill will make.

An Ideal World

In an ideal world the following could happen.

  • Every fast train to London, would be met at Broxbourne station by a paired slow train and passengers would take a train according to their needs, by just walking across the platform.
  • The next stop for the fast train would be Liverpool Street or Stratford, after running down the new fast line at a speed approaching 100 mph.
  • The slow train would stop everywhere, but arrive at Tottenham Hale in a time, that fast trains achieve today.

Coming out from London, the process would reverse.

No journeys would take longer than now, but some would be several minutes quicker.

All changes would be cross-platform at Broxbourne.

The Design Of The Fast Lines

If the fastest route between A and B, where there is no direct train, is to change at Broxbourne, there would never be a need to change anywhere else, so the only station with platforms on the fast and slow lines is Broxbourne.

Conclusion

I’m probably not exactly right here, but if the Crossrail actual and proposed timings are correct, there is a substantial time saving to be made.

The fast lines can also be very simple without platforms, which means that at stations like Tottenham Hale, Enfield Lock and Waltham Cross, it might be possible to squeeze the lines in.

West Anglia Route Improvement

I have decided to bring all of my posts on the following subjects together under a tag of West Anglia Route Improvement.

  • STAR – The local Stratford-Tottenham-Angel Road service connecting the Meridian Water development to Tttenham Hale and Stratford stations.
  • Crossrail 2 along the Lea Valley.
  • Four tracking of the West Anglia Main Line between Tottenham Hale and Broxbourne.
  • Station Improvements between Tottenham Hale and Broxbourne.

I also suspect other subjects connected with the improvement of the West Anglia Main Line and other related rail routes will also be added.

West Anglia Route Improvement – Modern Railways March 2017

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

They state  the following about the current works.

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

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

They also state this about Crossrail 2

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

So how does all this fit with my observations?

STAR

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

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

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

The timings from Tottenham Hale are currently as follows.

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

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

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

STAR At Tottenham Hale

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

Not Much Space For Two Tracks

Note the newly-installed cable ducts.

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

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

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

Platform usage at Tottenham Hale would be as follows.

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

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

STAR At Angel Road

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

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

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

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

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

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

STAR At Northumberland Park

This picture shows the current works at Northumberland Park station.

Northumberland Park Station

This picture was taken from the footbridge in the station.

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

I suspect the answer is in the affirmative.

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

STAR At Lea Bridge Station

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

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

 

Alongside Lea Bridge Station

 

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

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

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

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

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

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

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

STAR at Stratford

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

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

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

But there may be other possibilities!

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

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

stratfordlines

Use of the High Meads Loop would enable the following.

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

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

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

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

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

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

The Stratford/High Meads Advantage

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

All of these construction projects need to be carried out.

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

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

STAR And Electrification

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

Ferry Lane Bridge At Tottenham Hale Station

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

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

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

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

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

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

Crossrail 2

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

Crossrail 2 Would Be Overlaid On The Existing Network

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

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

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

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

At present the following happens at Coppermill Junction.

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

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

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

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

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

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

These movements will need a very complicated Coppermill Junction.

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

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

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

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

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

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

Crossrail 2 Would Emerge From The Tunnel South of Tottenham Hale

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

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

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

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

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

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

,

STAR Would Be Built To Facilitate Four-Tracking

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

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

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

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

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

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

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

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

This would mean.

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

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

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

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

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

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

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

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

Passenger numbers and patterns will decide.

A Turnback Platform Is Being Considered At Tottenham Hale

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

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

It certainly couldn’t be described as good engineering.

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

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

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

Nothing is said about a turnback platform.

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

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

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

A Turnback Platform Is Being Considered At Enfield Lock

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

enfieldlock2

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

In Level Crossing Issues, I said this.

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

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

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

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

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

Turnback Platforms And Stabling Sidings Are Considered At Broxbourne

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

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

The station is even Grade II Listed.

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

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

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

Other Questions And Issues

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

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

Like Coppermill Junction, it will all get very complicated.

Conclusion

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