Class 321 Renatus Trains At Wickford And On The Crouch Valley Line

This article on Rail Advent indicated that the platform extension at Wickford station had been completed, so that five-car Class 720 trains can work the Crouch Valley Line.

This morning I went to look at the progress and took these pictures.

Note.

  1. Platform 1 has been extended at the London end.
  2. The two trains working the branch were Class 321 Renatus trains.
  3. The stations on the branch seemed to have been spruced up.

I suspect Greater Anglia are expecting a lot more commuters and visitors.

  • But then the area is getting a lot more housing.
  • There are fast direct trains to and from London Liverpool Street on a railway with refurbished electrification.
  • Burnham-on-Crouch is one of the foremost yachting towns.
  • Remember the area is not far from Snowgoose Country.
  • The new Wallasea wetlands that were created with the tunnel spoil from Crossrail’s tunnels is not far away.

This Google map shows Burnham-on-Crouch and Wallasea Wetlands.

Note.

  1. Burnham-on-Crouch with its station in the North-West corner of the map.
  2. Wallasea Wetlands are marked by the red arrow.

I don’t think it will be long before an appropriately-powered ferry is provided across the River Crouch.

I also have some thoughts.

The Class 321 Renatus Trains

The Class 321 Renatus trains may be a 2017 conversion of a 1990-built British Rail Class 321 train, but that doesn’t mean they are a cheap and nasty conversion.

So until all the Class 720 trains are in service, they are a more than adequate stand-in.

I was told that the Class 720 trains will be in service on the branch in September.

The Snow Goose

The Snow Goose is one of the great books of the Twentieth Century, written by the American; Paul Gallico.

This summary of the plot is from Wikipedia.

The Snow Goose is a simple, short written parable on the regenerative power of friendship and love, set against a backdrop of the horror of war. It documents the growth of a friendship between Philip Rhayader, an artist living a solitary life in an abandoned lighthouse in the marshlands of Essex because of his disabilities, and a young local girl, Fritha. The snow goose, symbolic of both Rhayader (Gallico) and the world itself, wounded by gunshot and many miles from home, is found by Fritha and, as the human friendship blossoms, the bird is nursed back to flight, and revisits the lighthouse in its migration for several years. As Fritha grows up, Rhayader and his small sailboat eventually are lost in the Dunkirk evacuation, having saved several hundred men. The bird, which was with Rhayader, returns briefly to the grown Fritha on the marshes. She interprets this as Rhayader’s soul taking farewell of her (and realizes she had come to love him). Afterwards, a German pilot destroys Rhayader’s lighthouse and all of his work, except for one portrait Fritha saves after his death: a painting of her as Rhayader first saw her – a child, with the wounded snow goose in her arms.

It is not a book, you’d expect an American to write about the dark days of World War II in the UK.

But as Christopher Nolan showed in his film, Dunkirk was the battle in World War II, that stiffened up the sinews and summoned up the blood.

Wickford Station

The pictures show that Wickford station is being rebuilt.

I would think it needs a speed-free bridge.

Decarbonisation Of London’s Freight Routes

London has a rail capacity problem, for both freight and passenger trains.

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

Surprisingly, the report only mentions decarbonisation once and that is when it is talking about moving the AC/DC switchover point on the West London Line to Kensington Olympia station.

This section from the report describes how dual-voltage electrically-hauled freight trains would handle the electrification on the West London Line.

Although moving the changeover to Shepherd’s Bush would eliminate the need for passenger trains to slow down or stop at North Pole Junction, electrically hauled freight trains will still need to switch power supply modes whilst moving, wherever the AC/DC interface is located.

Due to the substantial incline facing trains running northward on the WLL, which increases in severity towards the Willesden end of the route, it would be preferable for the changeover to be made as far south as possible. This would enable freight trains to slow down to switch traction before reaching the worst of the gradient, giving them a much better chance of regaining line speed once drawing power from the OLE.

Although Kensington Olympia is less than a mile to the south of Shepherd’s Bush, the intervening route section is almost entirely level, with the incline commencing just before Shepherd’s Bush station and continuing to rise sharply along the rest of the WLL. The capacity and performance benefits of relocating the changeover are therefore likely to be greater if the overhead wires are extended to Kensington Olympia, removing the risk to traffic flow that would remain if freight trains were forced to switch whilst running uphill.

This would prepare the West London Line for the transition to electric freight that will be necessary as part of the decarbonisation of the railway over the next thirty years.

Resolving the current traction changeover issues for freight as well as passenger trains would support this transition by encouraging freight operators to invest in electric locomotives to run on the orbital routes, in the confidence that this constraint has been addressed.

Where is Network Rail’s guidance?

These are a few thoughts.

How Many Of The Freight Trains Through London Could Be Electrically-Hauled?

Most freight trains are hauled by diesel Class 66 locomotives.

But that doesn’t mean that these freight trains between say Ipswich and Cardiff are electrically-hauled on what is a fully-electrified route.

There are various reasons, why they aren’t.

  • There are large fleets of cheap, nasty and polluting Class 66 locomotives.
  • There isn’t many suitable electric locomotives.
  • The routes to major ports like Felixstowe, Immingham, London Gateway and Southampton are not electrified.
  • Many busy cross-country freight routes like Ipswich and Peterborough are not fully-electrified.

But powerful bi-mode electric-locomotives, like the Class 88 locomotives, that can do many tricky trips in the UK are available. Although there are only ten of them.

I have done a quick analysis and found the following.

  • There are a good proportion of lighter weight freight trains, that are not long and heavy.
  • There are a good proportion of freight trains running over routes that are electrified with 750 VDC third-rail equipment.
  • There are also some freight services, where a dual-voltage locomotive would be needed.
  • If a locomotive had a Last-Mile capability of perhaps forty miles, a lot of services could be electric-hauled.

Network Rail should do an analysis of all freight working in the various regions of the UK, to find out what are the needs of the electrically-hauled market in the various regions of the UK.

Could There Be A London Locomotive?

I wouldn’t want to get too regional, but looking at the figures, I think the following locomotive could be developed to handle freight trains in and through London.

I’m very much of the opinion, that the UK needs a battery-electric locomotive with the following capabilities.

  • The physical size and axle loading of a Class 68 or 88 locomotive.
  • Up to 4 MW when running on 25 KVAC overhead electrification.
  • Up to 2.5 MW when running on 750 VDC third-rail electrification.
  • Up to 2 MW for 30 minutes when running on battery power.
  • Regenerative braking to batteries.

Note.

  1. The axle load of a Co-Co Class 66 locomotive is 21.6 tonnes.
  2. The axle load of a Bo-Bo Class 88 locomotive is 21.5 tonnes.

But the overall weight of the Class 66 locomotive is fifty percent higher.

I believe, that a locomotive with this specification could replace the ubiquitous, cheap, smelly, polluting and carbon-emitting Class 66 locomotive on a lot of duties. Especially, in London and the South East, where there is a lot of running on tracks with 750 VDC third-rail electrification.

I believe that this locomotive would be able to haul some of the heaviest trains on these routes.

  • Ipswich and the Port of Liverpool via London.
  • Ipswich and Wentloog (Cardiff) via London.
  • Ipswich and Coatbridge via London.
  • Ipswich and Birmingham via London.
  • Ipswich and Crewe via London.

These routes cry out for the ability to be able to do the last miles into Felixstowe.

Ipswich And Felixstowe On Battery Power

If the diesel engine and all the associated gubbins are removed from a Class 88 locomotive, a battery with the same weight could be fitted into the locomotive, without unduly affecting handling or axle load.

Doing rough calculations, this battery would have a capacity of at least 1 MWh.

  • This battery would be able to supply 2.5 MW for twenty-four minutes, which would be a very valuable Last-Mile capability.
  • The battery would also enable regenerative braking to the battery, which would increase the energy efficiency of the locomotive.

These capabilities may open up the possibility of battery-electric haulage of some trains into and out of the Port of Felixstowe.

  • Freight trains take around 32 minutes to travel from the Great Eastern Main Line to the port.
  • Freight trains take around 36 minutes to travel from the port to the Great Eastern Main Line.
  • The route is fairly level although there is the climb over Spring Road viaduct.

If necessary, the route could be electrified, between the Great Eastern Main Line and Derby Road station.

  • The climb over the viaduct would be electrified.
  • Only 21 minutes of the route would not be electrified.

I believe that, it would be possible for Stadler to design a dual-mode battery-electric locomotive that could haul most of the heaviest trains into and out of the Port of Felixstowe.

This would effectively decarbonise a large proportion of freight traffic on the North London and Gospel Oak to Barking Lines.

Third-Rail Freight

In addition, a locomotive of this class, with a third-rail capability would be able to handle the numerous freight trains on the third-rail network.

With third-rail electrification, there are always worries that it can supply enough power.

  • A Class 66 locomotive has a diesel engine generating 2.5 MW.
  • An eight-car Class 700 train is rated at 3.3 MW. These trains are seen all over South London.
  • A Class 377 train is rated between 0.8 and 1.2 MW. Pairs of these trains are seen all over South London.

It would appear that an electric Class 66-sized locomotive would only draw the same power as typical trains on the third-rail network.

So perhaps a dual-voltage electric locomotive suitable for freight through much of South London, wouldn’t leave all of South London in the dark?

Junctions Which Need Upgrading

The London Rail Freight Strategy, identifies these junctions as needing an upgrade.

Would these junctions be easier to upgrade, if the designers of the junctions, knew that many more trains using the junction were to be hauled by powerful and spritely electric-haulage?

West London Line Issues

Two of the posts covering the London Rail Freight Strategy concern the AC/DC  switchover on the West London Line.

The proposed locomotive wouldn’t care where the switchover happened, as it would use batteries to achieve a smooth switchover.

Conclusion

The UK rail network needs a go-anywhere battery-electric locomotive.

Heavy Axle Weight Restrictions

London has a rail capacity problem, for both freight and passenger trains.

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

One of the secondary recommendations of the report is to improve the capacity to handle trains with heavy axle weight restrictions.

The report explains it like this.

In consultation with train drivers for the Freight Operating Companies and Network Rail structural engineers, this study has identified a list of Heavy Axle Weight restrictions on routes used by freight in London, which are known to negatively impact the movement of heavier trains around the
network.

The resulting proposal, as part of the LRFS, is for packages of works to enable the removal of these restrictions to be progressed.

A general package of cross-London interventions, targeting structures across a variety of routes, has been outlined for development. In addition, a large stretch of the Gospel Oak-Barking Line, where Heavy Axle Weight traffic is subject to a blanket 20mph speed restriction, should be the focus of a dedicated package of works to facilitate the removal of that restriction and to strengthen the route so that it is capable of accommodating future
rail freight growth.

Although these proposed packages of works should address the structures currently known to cause speed restrictions that negatively impact freight operations in London, maintaining the infrastructure to a level that can safely accommodate Heavy Axle Weight loads is an ongoing challenge for
Network Rail.

There are no permanent fixes when dealing with structures that have been bearing railway traffic since the nineteenth century. Ongoing maintenance funding to prevent the need for HAW speed restrictions to be imposed in the first place is just as critical as interventions to remove existing ones.

It sounds to me that, as with Gauge Improvements Across London, there needs to be a full survey to identify all the places, where heavy axle weight is a problem.

It does sound from the report, that some of the remedial works will not be trivial.

Conclusion

I don’t think Network Rail will be keen to rebuild all the freight routes through London.

East Coast Main Line South Bi-Directional Capability

London has a rail capacity problem, for both freight and passenger trains.

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

One of the secondary recommendations of the report is to use the bi-directional capability of the East Coast Main Line to create another freight route through London.

The report explains it like this.

The southern end of the East Coast Main Line, from Kings Cross to Stoke Tunnel (about five miles south of Grantham), is due to be the first part of a national main line to be fully converted to European Train Control System (ETCS) digital signalling.ETCS, because it does not rely on fixed lineside equipment facing one way or another, is bi-directional by nature.

This presents an opportunity for freight to make use of a new routeing at the southern end of the East Coast Main Line, which current signalling and track layout do not permit.

This strategy therefore proposes installing new track layout features that would facilitate this routeing for freight trains, enabling them to take advantage of the bi-directional capability brought about through ETCS deployment.

The main expected change would be the creation of a facing crossover at Bowes Park, to enable southbound freight trains to run onto the Down Enfield Viaduct in the up direction, before continuing onwards to the terminal at Ferme Park or accessing the Gospel Oak-Barking Line at Harringay.

This example shows an advantage of digital in-cab signalling.

This map from cartometro, shows the lines between Bowes Park and Alexandra Palace stations.

Freight trains coming from the North regularly take the Hertford Loop Line and arrive in North London at Bowes Park

Currently, they sneak down the Eastern side of the East Coast Main Line and then take a route across London, which probably uses the North London Line.

What is proposed is that with an extra crossover just South of Bowes Park station, freight trains will crossover and take Enfield Viaduct the wrong way to the Western side Alexandra Palace station.

The Enfield Viaduct is the track taken from Alexandra Palace station to Bowes Park station, by trains going to Enfield. It takes a bit of a loop to the West.

This second map from cartometro, shows the lines South of Alexandra Palace stations.

Note.

  1. Hornsey is the next station to the South of Alexandra Palace.
  2. The Eastern side of the East Coast Main Line is crowded with maintenance depots for trains.
  3. The orange line is the Gospel Oak to Barking Line.

By the use of digital signalling a new freight route through North London can been created.

Conclusion

How many other places can this technique be used?

Gospel Oak Speed Increases

London has a rail capacity problem, for both freight and passenger trains.

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

One of the secondary recommendations of the report is to increase speed through Gospel Oak.

The report explains it like this.

This proposal would see the current 20mph line speeds through Gospel Oak increased, through an upgrade to the junction immediately to the west of the station. Improving the flow of traffic through this critical flat junction, where the North London Line and Gospel Oak-Barking Line meet, would be of benefit for the wider operations and performance of these orbital routes. Freight trains in particular, which run non-stop through Gospel Oak, using all available routes, would see a notable uplift to how quickly they are able to pass through the area.

This would not only contribute to achieving the fast end-to-end cross-London paths that are a priority for freight but would also reduce the time trains would occupy the junction, increasing performance resilience at Gospel Oak, the impact of which would drive improvement right across the North London Line and Gospel Oak and Barking Line.

This map from cartometro shows the track layout at Gospel Oak.

Note.

  1. The double-track North London Line passing through Platforms 1 and 2 at Gospel Oak station.
  2. The double-track Gospel Oak and Barking Line passing to the North of the station.
  3. Platform 3 is a West-facing bay platform for services to Barking.
  4. There is no Westbound connection to Platform 3.
  5. All tracks in the map are hace 25 KVAC overhead electrification.

The two double-track railways merge west of the station at Gospel Oak junction.

This Google map shows the same area.

 

Note.

  1. Gospel Oak junction is in the North-West corner of the map.
  2. Platform 1 and 2 of Gospel Oak station are in the South-East corner of the map.

This Google map shows the junction to a larger scale.

There would appear to be space to the North of the junction for expansion.

It might even be possible to squeeze in another line, so that trains can go straight through at a faster speed.

Conclusion

This looks like another junction, that could be easy to improve on an engineering basis.

But whether the locals will accept it quietly could be another matter.

Gauge Improvements Across London

London has a rail capacity problem, for both freight and passenger trains.

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

One of the secondary recommendations of the report is to improve the gauge across London.

The report explains it like this.

The portfolio of options developed from this strategy needs to include a cross-London programme of gauge clearance, to address existing gaps and open up new market opportunities for rail freight in the long-term future.

Priorities in this area include:

  • Formal publication of W10 clearance on the North London Line from Kensal Green Junction to Acton Wells Junction. This section is currently only published as W9 but has been used for diversions of W10 traffic in the recent past.
  • Further work to understand what would be required to achieve W12 clearance on the North London Line and Gospel Oak-Barking Line.

This stands to enable rail freight to take advantage of emerging opportunities in the short-sea market from the Essex Thameside ports
and is a priority for stakeholders.

Continued development work towards gauge enhancement of the Channel Tunnel classic routes, which run through south and west London to Wembley.

The ultimate aim is to progress a programme of clearance works to achieve full W12, but opportunities to deliver incremental improvements by clearing for wagon and box combinations above what is possible today, but short of W12, are also being actively considered.

It appears to me, that a series of well-designed and well-defined projects is needed to update all those places, where loading gauge is insufficient.

In the Felixstowe And Nuneaton Freight Capacity Scheme, Phase 1 included increasing the loading gauge between Peterborough and Nuneaton to a loading gauge of W10.

This scheme involved the replacement of fourteen bridge and eleven tracking lowering/slewing schemes.

Conclusion

Gauge enhancement on a difficult railway has been performed successfully in several places in the UK and the bullet must be bitten to enhance the loading gauge appropriately, through London.

Longhedge Junction Speed Increases

London has a rail capacity problem, for both freight and passenger trains.

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

One of the secondary recommendations of the report is to increase speed through Longhedge junction.

The report explains it like this.

There is an opportunity to enhance Longhedge Junction, a key location for freight passing through the Battersea area, to enable higher speeds and provide faster transit between the South London Line and West London Line or Clapham Junction (for the Brighton Main Line or Windsor lines).

This would benefit the numerous freight flows through this important part of the network, where two orbital routes connect to each other and to radial routes in and out of London to the south and south-west.

London Overground SLL services running to and from Clapham Junction would also benefit from an increase to the existing 25mph line speed through Longhedge Junction.

This map from cartometro shows the location of Longhedge junction.

Note.

  1. The orange and black tracks are London Overground routes.
  2. The Overground route going East is the Dalston Junction and Clapham Junction service that goes via the South London Line (SLL).
  3. The Overground route going West is the Stratford and Clapham Junction service that goes via the West London Line (WLL).
  4. The two Overground routes combine to run into the Overground platforms at Clapham Junction.
  5. There is a double-track route, that links Latchmere 1 junction on the West London Line with Longhedge junction on the South London Line.
  6. Longhedge junction is in the East of the map.

It is an area congested with train tracks and junctions.

Traffic Through Longhedge Junction

Longhedge junction is busy, with the following trains in a typical hour.

  • Four tph between Dalston Junction and Clapham Junction stations.
  • Up to six assorted  freight tph.

Note that services run in both directions.

But this Google Map of the are gives hope.

Longhedge junction is to the West of the West of the tracks running North South and it looks like there could be plenty of space to realign the tracks and improve the junction.

As with Nunhead Junction, which I wrote about in Nunhead Junction Improvement, it could be that the use of electric haulage on freight trains through the junction with their more nimble acceleration might help.

Conclusion

This appears to be a serious problem.

What it needs now is a well-designed scheme to speed freight and passenger trains through the junction.

Ickenham Station Has Gone Step-Free

I wrote West London Stations To Be Made Step-Free in January 2018.

One of the stations on the list; Ickenham station, is now step-free.

These pictures showed the station, when I visited the station in early 2018.

And these show it, after the addition of step-free access.

It is a practical rather than architectural lift installation incorporating new walkways connecting the two lifts and the main entrance to the station.

  • Unlike many Underground stations, Ickenham station, does not appear to be Listed.
  • The cladding for the installation, appears to be in a slate-grey steel.
  • The stairs are still there for the agile.

As the pictures show the walkways are open to the elements, but there is enough headroom to use an umbrella.

Could London Overground Services To Stratford Be Extended To Meridian Water?

My arrival In Platform 11 at Stratford station has got me thinking!

And others too! Judging by the comments I’ve received.

Yesterday, I took a train from Dalston Kingsland station to Stratford station.

  • The train was the 0934 from Clapham Junction, which was timed to arrive in Stratford at 1038.
  • It arrived in Platform 11 at 1036.

In A London Overground Class 378 Train In Platform 11 At Stratford Station, I show pictures of the train in Platform 11 at Stratford station.

I suspected this was just a one-off occurrence, caused by a malfunction in a train or the signalling, which prevented my train from using the normal Platforms 1 or 2, that services to Stratford would use.

Although, looking at Real Time Trains, the 0938 train this morning, terminated in Platform 11. As it did on Monday and Tuesday this week.

  • This train was the only train from Clapham Junction station not to use Platform 2.
  • Checking days last week, it appears that this train always terminated in Platform 2.

So why did the service terminate in Platform 11?

Driver training is one possibility, so they can use the Platform 11, if there is a malfunction that stops them using Platform 2.

But is there a clue in the first picture, I took, when I arrived in Stratford?

The train in Platform 12 is the 1046 to Meridian Water, which arrived from Bishops Stortford at 1040.

Could it mean that there is to be a reorganisation of platforms at Stratford?

  • Platform 12 will be exclusively used by Greater Anglia for their West Anglia Main Line services.
  • Platform 11 will be used by London Overground.

In Using Platform 12 At Stratford Station, I described ending up on Platform 12, so I know it is possible, but when it happened information was bad for passengers, who didn’t know here they needed to go to continue on their way.

But why would London Overground need the extra platform?

These are my thoughts.

Do London Overground Need An Extra Platform At Stratford?

Currently London Overground services to Stratford are as follows.

  • Four tph – Stratford and Richmond
  • Four tph – Stratford and Clapham Junction

Note.

  1. tph is trains per hour.
  2. Both Class 378 and Class 710 trains can work the routes to Stratford.
  3. Eight tph can easily be handled by two platforms.

To handle more trains may need a third platform at Stratford for the London Overground.

Extra Trains Between Stratford And Canonbury

This report from Network Rail is entitled The London Rail Freight Strategy (LRFS).

It says this about creating a third platform at Camden Road station.

This proposal would reinstate a third track and platform on the northern side of Camden Road station, utilising part of the former 4-track formation through the station.

The additional capacity provided would facilitate much greater flexibility in pathing options for trains on this busy central section of the NLL, opening up new options for future service provision and bolstering performance resilience.

Reinstatement of a third platform would enable platform 2 to be used as a central turnback, with platform 3 becoming the eastbound line for through London Overground services and the majority of freight.

Transport for London modelling suggests that the eastern end of the NLL, from Canonbury to Stratford, will see some of the strongest long-term demand growth on the Overground network.

A turnback platform will allow this to be addressed with peak capacity boosting services between Stratford and Camden Road and there would also be the option to operate these through the off-peak, which could offer a means of providing additional passenger capacity where it is most needed.

The availability of an additional platform would also aid performance recovery during perturbation on
the orbital routes.

Note.

  1. The strongest passenger growth on the North London Line (NLL), will be between Canonbury and Stratford.
  2. Extra services are proposed between Stratford and Camden Road stations.
  3. If you travelled between Highbury & Islington and Stratford before the pandemic, the trains only had space for a few extra very small people in the Peak.

I use this section of the North London Line regularly and suspect the route needs at least twelve tph.

Twelve tph into Stratford would probably mean that the London Overground would need a third platform at Stratford.

More Trains Serving Meridian Water

In the Wikipedia entry for Meridian Water station, this is said.

In August 2019, it was announced that funding had been approved for construction of a fourth platform and a new section of track between Tottenham Hale and Meridian Water to enable up to 8 trains per hour to serve the station at peak times.

This must be the earliest upgrade in history, after a new station has opened.

I got the impression, when the station was announced that it would have four tph to Stratford. Currently, there are just two tph.

Two tph between Stratford and Bishops Stortford also pass through without stopping.

If these called at Meridian Water in the Peak, then there would still be four tph to find.

An easy way to create four tph between Stratford and Meridian Water would be to extend four London Overground services from Stratford.

  • Services would call at Lea Bridge, Tottenham Hale and Northumberland Park stations.
  • Trains would pass through Platform 11 at Stratford.
  • Platform 11 at Stratford would be bi-directional.
  • The service could be run all day, at a frequency of four tph.
  • As these trains have their own track, they won’t delay the Cambridge and Stansted trains on the West Anglia Main Line.
  • A cross-London service between Meridian Water and Clapham Junction or Richmond, would be possible.

Note.

  1. London Overground would be responsible for the bulk of the Meridian Water service.
  2. London Overground’s four- or five-car trains would probably have sufficient capacity for the service.
  3. The main new infrastructure needed would be the fourth platform and a new section of track at Meridian Water station.
  4. Some improvements as specified in the London Rail Freight Strategy will be useful, as they will increase capacity on the North and West London Lines.
  5. My only worry would be, that can modern signalling handle four tph in both directions through Platform 11 at Stratford station.

What Will Be The Track Layout And Method of Operation?

The current track layout is simple.

A bi-directional third track has been laid between Lea Bridge junction, just to the North of Lea Bridge station and Meridian Water station.

  • It is to the East of the double-track West Anglia Main Line.
  • There are bi-directional platforms at Tottenham Hale and Northumberland Park stations.
  • There is a single terminating Platform 2 at Meridian Water station.

A train going between Stratford and Meridian Water stations does the following.

  • Leaves from Platform 11 or 12 at Stratford station.
  • Calls in Platform 2 at Lea Bridge station.
  • Switches at Lea Bridge junction to the bi-directional third-track.
  • Calls in Platform 2 at Tottenham Hale station.
  • Calls in Platform 2 at Northumberland Park station.
  • Terminates in Platform 2 at Meridian Water station.

A train going between Meridian Water and Stratford stations does the following.

  • Leaves from Platform 2 at Meridian Water station
  • Calls in Platform 2 at Northumberland Park station.
  • Calls in Platform 2 at Tottenham Hale station.
  • Switches at Lea Bridge junction to the Up line of the West Anglia Main Line.
  • Calls in Platform 1 at Lea Bridge station.
  • Terminates in Platform  11 or 12 at Stratford station.

The track layout can probably handle a maximum of two tph.

I suspect the upgrade will build on this layout to allow a frequency of at least four tph.

The following works will be done.

  • A fourth track to the East of the bi-directional third track will be built.
  • The fourth track will run between Tottenham Hale and Meridian Water stations.
  • I suspect the fourth track will split from the third track at a junction to the North of Tottenham Hale station. Could this be called Tottenham Hale North Junction? I will use that name, to make things simple!
  • A new Platform 1 will be built in Meridian Water station.
  • Trains going North between Tottenham Hale and Meridian Water will use the current bi-directional third track and will be able to terminate in either Platform 1 or 2 at Meridian Water station.
  • Trains going South between Meridian Water and Tottenham Hale will use the new fourth track and will be able to start from either Platform 1 or 2 at Meridian Water station.
  • I suspect, Northumberland Park station will need a new Platform 1 for Southbound trains. But the station was designed with that in mind.

A train going between Stratford and Meridian Water stations will do the following.

  • Leave from Platform 11 or 12 at Stratford station.
  • Call in Platform 2 at Lea Bridge station.
  • Switch at Lea Bridge junction to the bi-directional third-track.
  • Call in Platform 2 at Tottenham Hale station.
  • Call in Platform 2 at Northumberland Park station.
  • Terminate in Platform 1 or 2 at Meridian Water station.

A train going between Meridian Water and Stratford stations will do the following.

  • Leave from Platform 1 or 2 at Meridian Water station.
  • Use the new fourth track to come South.
  • Call in Platform 1 at Northumberland Park station.
  • Continue on the bi-directional third-track at Tottenham Hale North Junction.
  • Call in Platform 2 at Tottenham Hale station.
  • Switch at Lea Bridge junction to the Up line of the West Anglia Main Line.
  • Call in Platform 1 at Lea Bridge station.
  • Terminate in Platform  11 or 12 at Stratford station.

The track layout is effectively two double-track sections linked by a bi-directional single track between Lea Bridge Junction and Tottenham Hale North Junction.

  • On the double-track sections of the route trains can pass each other, as they are on different tracks.
  • Lea Bridge and Tottenham Hale stations are 1.9 miles apart.
  • Trains take three or four minutes between Lea Bridge and Tottenham Hale stations. Including the stop at Tottenham Hale on the single track section.

If trains could alternate through the single-track section, this would give a capacity  of well over four tph in both directions.

  • A train going North would wait in Platform 2 at Lea Bridge station until the previous Southbound train had cleared Lea Bridge junction, before proceeding North.
  • A train going South would wait at Tottenham Hale North Junction until the previous Northbound  had safely passed, before proceeded South.

I suspect that the trains need full digital signalling with a degree of Automatic Train Control.

But I suspect we could see six tph in both directions.

  • This would fit nicely, with London Overground’s ambition of six tph on all routes.
  • It could be increased to eight tph in the Peak, by arranging for an appropriate number of Greater Anglia services to and from Liverpool Street at Meridian Water.

I feel that a service that meets all objectives will be possible.

Proposals From The London Rail Freight Strategy That Might Help

These proposals from the London Rail Freight Strategy might help.

It does look to me, that the London Rail Freight Strategy was designed with one eye on improving the passenger train service between North-East and South-West London.

Taking The Pressure Off The Victoria Line

Consider.

  • If you’re going between Walthamstow and the West End or the major stations of Euston, Kings Cross, St. Pancras and Victoria, you will use the Victoria Line.
  • If you live in the new housing, being built at Meridian Water, currently you will be likely to hop to Tottenham Hale station and take the Victoria Line.

Consequently, Northern end of the line can get busy! And not just in the Peak!

But a four tph service between Meridian Water and Stratford, will encourage passengers to go to Stratford to take advantage of the Central and Jubilee Lines and Crossrail.

Hence there will be less passengers, who need to use the Victoria Line.

A Better Interchange Between Camden Road And Camden Town Stations

The essential upgrade of Camden Town station has been put on indefinite hold due to TfL’s financial position.

This is a big mistake.

  • Camden Town station gets dangerously full!
  • It would allow the splitting of the Northern Line into two independent lines, which would increase capacity of the current system.
  • Camden Town station is not step-free but Camden Road station has lifts.

Hopefully, it would result, in a better route between the two stations, rather than the polluted route on a narrow pavement.

I very much believe that the rebuilding of Camden Town station is the most important project to improve London’s Underground and Overground network.

But it won’t get built with the current Mayor, as he’s a South Londoner.

Could A Meridian Water and Clapham Junction Service Be An  Affordable Crossrail 2?

Consider.

  • Crossrail 2 will link Clapham Junction and Meridian Water via Central London and Dalston.
  • A Meridian Water and Clapham Junction service would link the two stations via Shepherd’s Bush, Old Oak Common, West Hampstead, Camden Road, Dalston and Stratford.

Each route has their connectivity advantages.

  • Both have good connections to Crossrail, Thameslink and the Bakerloo, Central and Jubilee Lines.
  • The London Overground route has good connections to the Victoria Line and High Speed Two at Old Oak Common.
  • Crossrail 2 serves important stations in Central London.

A Meridian Water and Clapham Junction service could be a valuable addition to London’s rail infrastructure without too much new expensive infrastructure.

Conclusion

An extension of some London Overground services from Stratford to Meridian Water would be worthwhile.

Implementation of this is made easier by the recommendations of the London Rail Freight Strategy.

GWR To Test Battery Train On Branch Line

The title of this post, is the same as that of this article on Rail Business UK.

This is the first paragraph.

Great Western Railway has invited expressions of interest in trialling a battery powered train on the 4 km non-electrified branch line from West Ealing to Greenford in west London.

The article says that Vivarail have made a previous proposal, but other companies are also likely to declare their interest.

I feel some unexpected proposals could turn up.

The reason would be commercial,.

This is the last paragraph of the article, which says this.

The challenge on Great Western is we’ve got branches like Greenford, Windsor, Marlow and Henley along the Thames valley, and then in the West Country we’ve got St Ives, Falmouth, Newquay, Looe, Gunnislake and so on’, said Hopwood. ‘If we don’t electrify those could we fit the trains with a battery?’ The ideal solution may be a train that fast charges either at one end of the route or possibly at both ends, or on a route like Marlow, Gunnislake or Looe, where the trains reverse during their journey, could the charge point even be on that part of the branch?’

Note.

  1. Mark Hopwood is now the Managing Director of GWR.
  2. Nine branches are mentioned, so with spare trains and maintenance, it could be a good-sized order.

But this project could be even bigger.

South Western Railway are a sister company of Great Western Railway and in August 2020, I wrote Special Train Offers A Strong Case For Reopening Fawley Line about the plans to open the Fawley Line.

This was a section, I wrote about trains that might work the line.

South Western Railway’s Innovative Train Plan

This is another quote from the article.

However, SWR’s Mark Hopwood favours a much bolder plan. “We’d have to take a decision, once we knew the line was going ahead. But my personal belief is that we should be looking for a modern environmentally-friendly train that can use third-rail electricity between Southampton and Totton and maybe operate on batteries down the branch line.”

Pressed on whether that would mean Vivarail-converted former-London Underground stock, Hopwood ads. “It could be. Or it could be a conversion of our own Class 456, which will be replaced by new rolling stock very shortly. But I don’t think this is the time to use old diesels.

This is the same Mark Hopwood, who is now Managing Director of GWR.

These pictures show the current status of one of the twenty-four Class 456 train.

In Converting Class 456 Trains Into Two-Car Battery Electric Trains I discuss this conversion in detail.

Conclusion

Twenty-four battery-electric Class 456 trains would probably go a long way to satisfy GWR’s needs.
