Extending The Elizabeth Line – High Speed Trains On The Elizabeth Line

This may seem rather fanciful, but could it be the way to maximise the use of the Elizabeth Line?

  • I feel that the Elizabeth Line will eventually serve other destinations like Basingstoke, Beaulieu, Oxford, Southend and Swindon.
  • The capacity of the Elizabeth Line will grow to over thirty trains per hour (tph) under control of digital signalling.

These are a few thoughts.

The Design Of The Trains

As any train would have to be compatible with the platform-edge doors in the central tunnel of the Elizabeth Line, the trains would have to be dimensionally identical to the current Class 345 trains.

  • Nine cars
  • Possibility of lengthening to ten cars.
  • 204.73 metres long.
  • 6 sets of doors per carriage
  • Ability to run under full digital signalling.

They would be designed for a higher speed of at least 110 or 125 mph, to enable running on the fast lines of these routes.

  • East Coast Main Line
  • Great Western Main Line
  • Midland Main Line
  • West Coast Main Line

They would also be able to run at 100 mph on the Chiltern Main Line, the Great Eastern Main Line and the North Kent Line.

The faster running would ease scheduling of the trains.

Extra facilities could include.

  • Toilets
  • Tables
  • A third-rail capability for running in Kent.

Effectively, it would be a Class 345 train with more features and considerably more grunt.

Note that in A High Speed Train With An IPEMU-Capability, I started the post with the following.

Bombardier were reported by Ian Walmsley in the April 2016 Edition of Modern Railways, to be developing Aventra, with a 125 mph capability.

Bombardier have also told me, that all Aventras will be wired so they could be fitted with on-board energy storage.

Could it be that the design of a Class 345 train could be modified to run at higher speeds? I wouldn’t be surprised.

Oxford To Southend Victoria

This could be a typical route.

  • Between Oxford and Paddington, it would follow a route similar to the GWR’s Oxford service with stops at just Reading and Slough.
  • At Paddington the train would take the Central Tunnel of the Elizabeth Line and travel under London, at the same speed as the other trains.
  • It would emerge at Stratford and move to the Great Eastern Main Line.
  • It would probably stop at Stratford, Romford, Shenfield and all stations to Southend Victoria.

Note.

  1. Digital signalling would enforce the precise timekeeping needed.
  2. Much of the Oxford and Paddington section would be up to speeds of at least 125 mph.
  3. Times in the Central Tunnel of the Elizabeth Line would be identical to the current Class 345 trains.
  4. Much of the Stratford and Southend section would be up to speeds of at least 100 mph.

I estimate that total time would be a few minutes under two hours.

Connecting To The Central Tunnel Of The Elizabeth Line At Royal Oak

Connecting To The Central Tunnel Of The Elizabeth Line At Abbey Wood

This map from cartometro.com shows the track layout at Abbey Wood.

Note.

  1. The Elizabeth Line is shown in purple.
  2. The North Kent Line is shown in black.
  3. The North Kent Line platform to London is the Southernmost platform and is numbered 1.
  4. The North Kent Line platform from London is the other Southern platform and is numbered 2.
  5. The Elizabeth Line platforms are numbered 3 and 4.
  6. Platform 4 is the Northernmost platform.

At present the Elizabeth Line service to Abbey Wood station is twelve tph, with each platform handling six tph.

This picture shows trains in both Platform 3 and 4 looking towards the station buildings.

Note.

  1. Platform 3 is on the right.
  2. Platform 4 is on the left.

In Elizabeth Line To Ebbsfleet Extension Could Cost £3.2 Billion, I talk about this proposal as described in this article on Ian Visits.

One of the key features of Crossrail To Ebbsfleet (C2E) project is that instead of all trains terminating at Abbey Wood, trains will terminate as follows.

  • Abbey Wood – 4 tph
  • Northfleet – 4 tph
  • Gravesend – 4 tph

This will mean that 8 tph would pass through Abbey Wood station.

  • Platform 4 could certainly handle the four that terminated on the Elizabeth Line.
  • Platform 3 would need to handle eight tph in both directions or sixteen tph to fulfil the proposed C2E service.
  • This would be one train every 225 seconds.

I believe that digital signalling could handle this easily and safely.

I am fairly sure that the track layout at Abbey Wood allows eight tph to go both ways between the North Kent Line and the Elizabeth Line Central Tunnel.

The Maximum Capacity At Abbey Wood Station

Because of the current track layout at Abbey Wood, I believe that without track modifications, Abbey Wood station will not be able to handle more than 12 tph.

Thameslink

These proposed trains would also be compatible with Thameslink, as this route has no platform edge doors.

No platform extensions would be needed, as the Class 345 trains are shorter than the 12-car Class 700 trains.

If they were 125 mph trains, then this would ease timetabling on the East Coast Main Line, as the trains could mix it with the expresses on the fast lines.

Could These High Speed Trains For The Elizabeth Line Have A Cruising Speed Of 140 mph?

It is likely, when full authority digital ERTMS signalling is installed on main lines out of London, that 140 mph will be possible on some at least these routes.

  • East Coast Main Line
  • Great Western Main Line
  • Midland Main Line
  • West Coast Main Line

The extra speed would maximise capacity.

Extending The Elizabeth Line – An Extension To Southend Airport

The Wikipedia entry for Crossrail, has a section for an extension to Southend Airport, where this is said.

Stobart Aviation, the company that operates Southend Airport in Essex, has proposed that Crossrail should be extended beyond Shenfield along the Shenfield–Southend line to serve Southend Airport and Southend Victoria. The company has suggested that a direct Heathrow-Southend link could alleviate capacity problems at Heathrow. The extension proposal has been supported by Southend-on-Sea City Council.

I have written about extending Crossrail to Southend before in Council Launches Campaign To Extend Crossrail To Southend-on-Sea.

In that post, I gave these reasons.

  • Extra capacity between London and Southend
  • A more intensive service to Southend Airport
  • A twenty-four hour service to Southend Airport
  • Enabling housing
  • Taking pressure from Liverpool Street

I came to the conclusion, that extending the Elizabeth Line to Southend could have a lot going for it.

Times Change

But that post was written nearly four years ago and times change and they will change more in the next few years.

The Elizabeth Line Trains Are Shorter Than The Liverpool Street And Southend Victoria Trains

This has also happened and the pair of five-car Class 720 trains, that Greater Anglia use for Southend Victoria services are over thirty metres longer than the Elizabeth Line’s nine-car Class 345 trains.

This would mean that there would be no need for platform lengthening along the route to Southend Victoria.

Zero-Carbon Aircraft Are Under Development

Zero-carbon aircraft like the Heart Aerospace ES-19 could be in service by 2027. These aircraft will probably have a limited range of around 400 km and a charge time of 40 minutes.

  • Southend Airport’s position on the East side of London would enable the creation of zero-carbon flights to places like Amsterdam, Brussels, Lille, Paris and Rotterdam.
  • A quick estimate indicates that aircraft like the ES-19 could fly from Southend to Amsterdam and recharge in around two hours.
  • Intensively scheduled, these electric aircraft could make several round trips per day.
  • Would almost silent electric aircraft be able to fly twenty-four hours per day?

These flights could seriously increase the number of passengers to Southend Airport before the end of the decade.

More Housing

I think more housing will be built between Shenfield and Southend, which will increase the need for more services past Shenfield.

The Great Eastern Main Line Will Have Full Digital Signalling

More and more trains will be running on the Great Eastern Main Line and like other main lines in the UK, it will receive full digital signalling, which would probably be applied to the Shenfield and Southend Line.

This would give the extra capacity to Southend Victoria, that running the Elizabeth Line to Southend Airport and Southend Victoria would need.

Possible Services

I think there are two main possible options, but there may be others.

  • A long Elizabeth Line extension all the way to Southend Victoria.
  • A short Elizabeth Line extension only as far as Southend Airport.

My feelings are as follows.

  • The Greater Anglia service should remain as it is with three trains per hour (tph) calling at all stations to Shenfield, Stratford and Liverpool Street.
  • Perhaps three or four Elizabeth Line tph would extend to Southend Victoria, calling at all stations.
  • All Elizabeth Line trains would call at all stations to and from London, as they do now!

Full digital signalling would handle the extra trains.

 

Conclusion

I think it will be unlikely that the Elizabeth Line will be extended to Southend in the next few years, but before the end of the decade, I can certainly see limited  Elizabeth Line services going all the way to Southend Victoria.

Ryanair To Open New Base at London Southend Airport

The title of this post, is the same as that of this article in the Guardian.

The title gives most of the story, although the article says that flights won’t start until April 2019.

The article also contains this classic example of Ryanair-speak from their airline’s chief commercial officer, David O’Brien.

O’Brien said disruption from European air traffic control strikes, primarily in France, could be the “worst ever” for airlines, which cancelled 1,100 flights in May. “Your tourist going from Britain down to Spain is screwed by a couple of hundred French air traffic controllers,” he said.

The Wikipedia entry for Southend Airport gives these places as Ryanair’s destinations.

Alicante, Bergamo, Bilbao, Brest, Corfu, Cluj-Napoca, Dublin, Faro , Košice, Málaga, Palma de Mallorca, Reus and Venice.

This is a paragraph from the article.

Southend’s deal with Ryanair will double passenger numbers at an airport that only reopened six years ago. Its rapid expansion is set to continue, according to the chief executive of its owners, the Stobart Group. “We have a clear and focused strategy to grow our airport to welcome over 5 million passengers a year by 2022,” he said.

That number of passengers would put Southend Airport in the top dozen airports in the UK.

It’s a bit different to when I learned to fly at the Airport in the 1970s.

In those days, the only commercial traffic was the odd Carvair ferrying five cars and a score of passengers across the Channel.

I think Southend Airport will continue to grow for the following reasons.

  • Planes to and from the Airport can avoid the busy airspace over London.
  • The location and the prevailing Westerly winds,  allows pilots on some routes to bring the planes straight in, saving a lot of time.
  • Being early encourages passengers to use the Airport again and tell their friends.
  • Southend Airport station is less than a hundred metres away.
  • The City pf London is about an hour away.
  • Currently, the train service is three trains per hour (tph) between Liverpool Street and Southend Victoria stations.
  • Greater Anglia is getting new Class 720 trains and trains to the Airport may be increased in frequency.
  • Crossrail and Greater Anglia will bring increasing numbers of passengers to Shenfield station for trains to the Airport.

I think it ls inevitable, that as the traffic at the airport grows, that Crossrail will be extended to Southend Airport and Southend Victoria stations.
