Technology Behind Siemens Mobility’s British Battery Trains Hits The Tracks

This title of this post is the same as that of this news item from Siemens, which was published in December 2024.

These three bullet points introduce the news item.

  • The Mireo Plus B battery train is rolled out in the East Brandenburg network, Germany, using the same technology as the British Desiro Verve project.
  • The Desiro Verve would save £3.5 billion and 12 million tonnes in CO2 emissions for Britain’s railways over 35 years.
  • The development marks the latest step of this technology’s journey to Britain’s railways.

No-one, including me, seemed to have spotted this news item, especially, since it is significant to both the UK and Germany.

But then parts of Siemens’s home country; Germany and Yorkshire, where they are building, a train factory to build London’s new Piccadilly Line trains have  something big in common – There is a distinct shortage of electric trains and the overhead wires to power them.

So did German engineers, egged on by pints of British real ale, realise that their battery-electric technology for the Mireo Plus B battery-electric train, would turn a Desiro City multiple unit, like the Class 700, 707 or 717 into battery-electric trains.

These are three paragraphs from the Siemens news item.

The innovative technology behind Siemens Mobility’s British battery trains has been rolled out in the East Brandenburg network in Germany.

31 of the company’s Mireo Plus B trains are being phased in to the Berlin Brandenburg metropolitan region, beginning on Sunday (15 December) and is the latest proof point of the technology that underpins the Desiro Verve project in Britain. This follows the debut of this technology on 27 new trains in the Ortenau region of Germany in April, with more set to arrive in Denmark in 2025.

The British Desiro Verve trains would be assembled at Siemens Mobility’s new Train Manufacturing Facility in Goole, East Riding of Yorkshire, formally opened by the Transport Secretary and Mayor of London in October.

I’d always wondered, what Siemens would do with this factory, when it had finished making the Piccadilly Line trains.

It also should be noted, that the boss of Siemens UK, when the Goole factory was planned was Jürgen Maier, who according to his Wikipedia entry has Austrian, British and German citizenship and is now the boss of Great British Energy.

I believe that Siemens have big plans for the Goole factory.

One thing it has, that at the present time could be a problem in Germany, is large amounts of renewable electricity and hydrogen, so will energy-intensive components for trains be made at Goole?

It will be interesting to see how the Goole factory develops.

The Desiro Verve Train For The UK and Ireland

In the Siemens news item, their Joint CEO for the UK and Ireland; Sambit Banerjee, says this.

The Desiro Verve would be assembled at our state-of-the-art Goole Rail Village in Yorkshire and offers an integrated solution to replace Britain’s aging diesel trains without having to electrify hundreds of miles of track, saving the country £3.5 billion over 35 years and providing a practical path to decarbonising British railways.”

In June, Siemens Mobility identified how the Desiro Verve could save Britain’s railways £3.5 billion over 35 years compared with using diesel-battery-electric ‘tri-mode’ trains. This would support the Government’s aim of removing diesel-only trains from Britain’s railways by 2040.

The British trains would be powered by overhead wires on already electrified routes, then switch to battery power where there are no wires. That means only small sections of the routes and/or particular stations have to be electrified with overhead line equipment (OLE), making it much quicker and less disruptive to replace diesel trains compared to full electrification.

I agree with his philosophy.

The Rail Charging Converter

When I wrote Cameron Bridge Station – 15th May 2025, I described how a short length of overhead electrification could be erected at the station to charge passing trains, using their pantographs.

Cameron Bridge station is lucky in that there is already a 132,000 KVAC electricity connection to the distillery next door.

But at other places, where there is no connection, you could wait as long as seven years to be connected to the grid.

So Siemens have come up with the Rail Charging Converter, that provides a local electricity supply to support the charger.

It is described in this paragraph from the news item.

This OLE can also be installed much more quickly using Siemens Mobility’s innovative Rail Charging Converter (RCC), which makes it possible to plug directly into the domestic grid – potentially cutting delivery times for OLE from seven years to as little as 18 months.

This Siemens visualisation shows a Verve train and an RCC.

This arrangement could be used in sensitive countryside or close to historic buildings.

Modern Railways – June 2025

There is an article about the Siemens technology in the June 2025 Edition of Modern Railways.

It is called The Battery Revolution Starts In Long Marston for which this is part of the sub-heading.

New technology being installed by Siemens Mobility at Porterbrook’s test facility paves the way for widespread use of battery trains in the UK.

The article is a must-read.

Conclusion

Siemens appear to have the technology with their Rail Charging Converter and battery-electric trains like the Verve and the Mireo Plus B, to be able to decarbonise lines without electrification all over the world.

Would larger gauge trains be delivered from Germany and smaller gauge ones from Goole?

I wouldn’t be surprised that a version for a German S-Bahn could share more characteristics, with a small British train, than a large German one.

I can also see an underground railway, that was built without power in the tunnels. So if you were building the Waterloo and City Line today, would it be battery-electric and charged at each end of the line using a pantograph?

Brent Cross West Station – 10th December 2023

The new Brent Cross West station opened today, so I went to have a look.

Note.

  1. There are two island platforms.
  2. The platforms can handl2 12-car Class 700 trains.
  3. The Eastern island, which is Platforms 1 and 2, is for Thameslink and has two escalators, two lifts, two sets of stairs and two toilets.
  4. The toilets on the Eastern platforms are an identical pair to cater for everyone.
  5. The Western island, which is Platforms 3 and 4, is for the main lines and has one lift and two sets of stairs.
  6. The arriving Thameslink Class 700 train is stopping in Platform 1 on the way to London.
  7. Signs indicate a cafe, but I couldn’t find it, so I assume that is for the future.
  8. The shelters on the platforms are heated.
  9. Both entrances have two lifts, at least one or two escalators and stairs.

The outside photos were taken two days later.

I have some other thoughts.

The Station Layout

The station has a slightly unusual and very practical layout.

  • There is a longish and high bridge over the multiple tracks through the station.
  • It is step-free with lifts and escalators at each end to give step-free access across the railway.
  • The bridge is wide and is built for cycles.
  • The trains are accessed from a spacious lobby, which is separated from the bridge by a long gate-line.
  • The lifts, stairs and escalators all lead down from the spacious lobby.

The station must have a very high passenger capacity.

The Track Layout

This OpenRailwayMap shows the track layout at the station.

Note.

  1. The Eastern island platform between the 90 mph Thameslink tracks.
  2. The Western island platform between the 100-105 mph main line tracks.
  3. The two most-Easterly tracks give access to the Cricklewood Depot.
  4. The two black tracks
  5. The blue tracks connect to the Dudding Hill Line.
  6. The two black tracks between the blue tracks and the main line tracks are the Up and Down Hendon tracks, which run between Hendon and West Hampstead Thameslink stations, which seem to allow trains to cross over from one side of the tracks to the other.

The large number of tracks must make operation easier.

The West London Orbital Railway

The Hendon and Kew Bridge route of the West London Orbital Railway is planned to call at Brent Cross West station.

It looks like it will use the two Hendon tracks through Brent Cross West and Hendon stations and trains will take the Dudding Hill Line to Neasden to the South of Brent Cross West station.

The West London Orbital Railway will connect Hendon and Brent Cross West station to High Speed Two and the Elizabeth Line, so it will be a very important connection for the residents of the area.

This OpenRailwayMap shows the track layout between the Dudding Hill Line and Hendon.

Note.

  1. Hendon station is in the North-West corner of the map.
  2. The orange tracks are the Midland Main Line
  3. Brent Cross West station is marked by the blue arrow.
  4. The yellow tracks going towards the South-West are the Dudding Hill Line.

The Hendon route will need new platforms at Hendon and Brent Cross West station.

Conclusion

I like the station and I think others will be built on similar principles.

125 mph Upgrade For MML OLE South Of Bedford

The title of this post, is the same as that of an article in the June 2023 Edition of Modern Railways.

This is the sub-heading.

Targeted Investment Benefits From Project SPEED Approach

The main objective was to upgrade the 1980s electrification between Bedford and St. Pancras, so that it could support 125 mph running by East Midlands Railway’s new Class 810 trains.

Originally, a total replacement was envisaged, but in the end a more selective approach will be carried out.

This paragraph indicates the benefits of the approach.

The proposal for wholesale replacement of the OLE South of Bedford would have cost several hundreds of millions of pounds, whereas the approved scheme comes in at just £84 million, around one-third of the previous cost – testament to the application of SPEED principles.

I have a couple of thoughts.

Network Rail’s Project Management

If I go back to the 1970s and 1980s, when we were developing and selling the project management system; Artemis to the world, we sold very few systems to the UK Government and none to British Rail or the NHS. Later Artemis was used on the Channel Tunnel and the Rail Link to London, the Jubilee Line Extension, sections of the Docklands Light Railway and railways in Australia and Hong Kong.

So it is good to see, Network Rail getting to grips with managing the electrification upgrade of the Midland Main Line with some good project management.

An Encounter With A Group Of Drivers

It might have been five years ago, when I travelled with a group of drivers from East Midlands Trains positioning to St. Pancras.

  • One of the observations they had was that the Class 700 trains coming into service were not fast enough as they were only 100 mph trains, whereas their Class 222 trains were capable of 125 mph.
  • Since then the Class 360 trains have been introduced on Corby services. These trains have been uprated from 100 to 110 mph.
  • We now have the situation, where Class 810 trains capable of running at 125 mph will replace the Class 222 train.

If you look at the traffic  at West Hampstead Thameslink station, you can see that Both Thameslink and East Midlands Railway are using the fast lines, through platforms 3 and 4.

The fast lines have a maximum speed of 125 mph North of Luton and generally 100-110 mph between Luton and West Hampstead Thameslink station.

Would it help the timetabling of services on the Midland Main Line, if the Thameslink services  were capable of running faster, when they were using the fast lines?

I feel the drivers may have a point.

Govia Thameslink Railway Issues a Prior Information Notice For New Trains

This article on Railway Gazette is entitled UK Railway News Round-Up and contains this section.

Govia Thameslink Railway has issued a prior information notice seeking the provision of between 21 and 30 four-car 25 kV 50 Hz 160 km/h through-gangwayed EMUs with air-conditioning and toilets for use on existing and/or additional Great Northern services from May 2024. Maintenance would be undertaken in-house at Hornsey depot, supported by a Technical Support & Spares Supply Agreement.

I find this all a bit puzzling.

  • The trains that need replacing are surely the eighteen Class 313 trains, that run on the West Coastway Line, as they are some of the oldest trains on the UK network.
  • If Govia Thameslink Railway were serious about decarbonisation, they would also replace the Class 171 diesel trains, that work the Marshlink Line and the Uckfield branch, with electric trains with a range of thirty miles on batteries.

How many trains would be needed to replace the Class 313 and Class 171 trains?

  • The eighteen three-car Class 313 trains could be replaced with an equal number of new four-car trains and this might result in a rise in passenger numbers.
  • I would assume the eighteen trains includes allowances for trains in maintenance and spare trains for when a train fails.
  • It may be possible to  replace the six four-car Class 171 trains used on the Marshfield Line with three new four-car trains, which have a range of thirty miles on batteries.
  • The eleven two-car Class 171 trains used on the Uckfield branch could be replaced with three new four-car trains, which have a range of thirty miles on batteries and would run as four-car trains.
  • If eight-car trains were needed on the Uckfield branch, there would be a need for six new four-car trains.
  • If twelve-car trains were needed on the Uckfield branch, there would be a need for nine new four-car trains.

Note.

  1. If four-car trains are needed on the Uckfield branch, this means a total of 18+3+3 or 24 trains.
  2. If eight-car trains are needed on the Uckfield branch, this means a total of 18+3+6 or 27 trains.
  3. If twelve-car trains are needed on the Uckfield branch, this means a total of 18+3+9 or 30 trains.

Trains on these Southern routes wouldn’t be stabled at Hornsey depot, but could be moved to Hornsey for maintenance  using Thameslink.

But the puzzling bit is that the prior information notice says that the trains will be.

Four-car 25 kV 50 Hz 160 km/h through-gangwayed EMUs with air-conditioning and toilets for use on existing and/or additional Great Northern services from May 2024.

Note.

  1. There is no mention of the trains being able to run on 750 VDC third-rail infrastructure.
  2. The trains will run on Great Northern services and the Class 313 and Class 171 trains run on Southern routes.
  3. The only Great Northern services, that have not been moved to Thameslink are Kings Cross and Cambridge, Ely and King’s Lynn and services to Moorgate.
  4. The Moorgate services have their own dual-voltage Class 717 trains.
  5. Govia Thameslink Railway have ambitions to double the frequency of trains to King’s Lynn.
  6. Two eight-car trains per hour (tph) between King’s Cross and King’s Lynn would need sixteen operational four-car trains.
  7. Two twelve-car trains per hour (tph) between King’s Cross and King’s Lynn would need twenty-four operational four-car trains.

If Govia Thameslink Railway are thinking of thirty new trains, they must have other destinations in mind.

Could we be seeing a double swap?

  • An appropriate number of new trains are procured to run Great Northern services between Kings Cross and Cambridge, Ely and King’s Lynn.
  • The Class 387 trains released will be moved to the South to replace the Class 313 and Class 171 trains.
  • Some or all of the transferred Class 387 trains will be fitted with batteries to give a range of thirty miles without electrification.

Note.

  1. Could the new trains be Siemens Desiro City trains like the Class 700 and Class 717 trains, which are already maintained at Hornsey depot? It would surely be more efficient and save money.
  2. Class 387 trains are dual voltage and would need little or no modification to replace the Class 313 trains.
  3. Uckfield and Hurst Green junction is 24.7 miles.
  4. Ashford International and Ore is 25.4 miles
  5. Adding a battery to a Class 387 train has not been done, but Bombardier converted a near-identical Class 379 train to battery-electric operation over eight years ago.
  6. Converting a Class 387 train gives a dual-voltage battery-electric train.
  7. I suspect a charger would be needed at Uckfield. Could it be a short length of 25 KVAC overhead electrification?

Could all the Class 387 trains, that will replace the Class 313 and Class 171 trains be identical to ease the problems, when a train develops a fault?

Conclusion

It looks a good plan.

It also opens up the following possibilities.

  • Deployment of 750 VDC battery-electric trains on other routes.
  • Deployment of 25 KVAC overhead battery-electric trains on other routes.
  • Deployment of tri-mode battery-electric trains on other routes.
  • Charging of battery-electric trains using a short length of 25 KVAC overhead electrification.
  • Fitting of batteries to Class 379 trains to create a 25 KVAC overhead battery-electric train.

It might be possible to convert other Electrostars to battery-electric operation.

Ignoring Class 387 trains on dedicated services like Heathrow and Gatwick Express, these trains are available for conversion.

  • Class 379 trains – Stored – 30 trains
  • Class 387 trains – Govia Thameslink Railway – 40 trains
  • Class 387 trains – Great Western Railway – 33 trains

Note.

  1. This gives 103 trains.
  2. They all have good interiors.
  3. They are all 100/110 mph trains.
  4. All trains could be updated to 110 mph.
  5. All trains can use 25 KVAC overhead electrification.
  6. The Class 387 trains can also use 750 VDC third-rail electrification.
  7. The Class 379 trains were built in 2010-2011.
  8. The Class 387 trains were built from 2014.

I believe both classes will make excellent battery-electric trains.

Where will they be deployed?

These are a selection of routes starting in the South-East of England.

  • Ashford International and Eastbourne.
  • Gravesend and Hoo.
  • London Bridge and Uckfield.
  • London Paddington and Bedwyn.
  • London Paddington and Oxford.
  • Reading and Basingstoke.
  • Reading and Gatwick.
  • Reading and Redhill.
  • Slough and Windsor & Eton Central.
  • Twyford and Henley-on-Thames

I’ve only added routes which are less than thirty miles.

Cambridgeshire Company’s Self-Charging Trains Project Wins Government Funds

The title of this post, is the same as that of this article on the BBC.

These four paragraphs outline what the company is developing and how they received government funding.

Echion Technologies, based in Sawston near Cambridge, is creating train batteries that can charge from overheard wires, the Department for Transport said.

The trains would be able to use the batteries on unelectrified track.

The project was among the winners of the government’s First of a Kind competition.

The competition aims to award funding to projects that could transform the future of transport.

I have a few thoughts.

The Description In The First Of A Kind 2022 Winners Document

In this document, this is said.

Project No: 10039100

Project title: UBER – Ultra-high power Battery for low Emission Rail
Lead organisation: ECHION TECHNOLOGIES LTD
Project grant: £59,917

Public description: Project UBER (Ultra-high power Battery for low Emission Rail), aims to demonstrate for the first time, Echion’s XNO(tm) battery chemistry as the preferred battery technology for certain classes of battery electric trains. It targets Theme 1 of this competition.

Specifically, UBER aims to demonstrate the suitability of XNO(tm) for passenger trains that can be powered by the AC overhead electrification and charge a battery from the overhead wire (or another form of ‘standard’ trackside power — e.g. 3rd rail), to then run in battery-only mode on unelectrified section of a route. An example of such a train is the Revolution Very Light Rail (Revolution VLR) developed by Transport Design International (TDI), who is a partner in UBER.

Applying The Echion Technologies Batteries To Electric Trains

Consider.

  • The BBC article is accompanied by a picture of a Class 717 train, which like the Class 700 train is dual voltage.
  • Southeastern have thirty similar Class 707 trains, which are third-rail, although according to Wikipedia, were tested as dual-voltage trains.
  • Most modern trains, like these Desiro City units made by Siemens, have a mix of motored and trailer cars, with one or more pantograph cars  between the two driver cars.
  • Because power is needed in all cars, there will be an electrical bus from one end of the train to distribute power.
  • All trains in the family appear to have at least one trailer car, which will also be connected to the electrical bus.

With a family of trains like the Desiro City, Alstom’s Aventra, CAF’s Civity, Hitachi’s AT-200 or AT-300 or Stadler’s FLIRTs, train manufacturers assemble various cars, interiors and electrical gubbins together, to get the train performance and capability.

I would expect that the battery would be placed, where there is space and the most likely place is under the trailer car.

In some ways, it would work like the battery in a laptop computer, where operation is as follows.

  • If there is external power, the computer runs on that power and the battery is also charged, if it is not fully-charged.
  • If there is no external power, the computer runs on battery power, until the battery goes flat.

With a battery-electric train, operation is similar, with an important addition.

  • If there is external power, the train runs on that power and the battery is also charged, if it is not fully-charged.
  • If there is no external power, the train runs on battery power, until the battery goes flat.
  • Desiro City and many other electric trains have regenerative braking and under braking, the electricity generated is is stored in the battery, if it is not fully-charged.

It could be considered by some, that regenerative braking is self-charging. But unfortunately, regenerative braking doesn’t recover all energy during braking. But it can be up to 70-80 % efficient.

Connecting The Echion Technologies Battery To The Train

The battery will have to be connected to the electrical bus, that runs the full length of the train.

As a Control Engineer, I suspect there will be a sophisticated control system, that will switch the battery between various modes and control the pantograph and third-rail shoes.

Perhaps, Echion Technologies have developed an all-purpose controller that could fit all trains?

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

I discuss this in Extending The Elizabeth Line – Connecting Great Western Main Line Services To The Central Tunnel.

Connecting To The Central Tunnel Of The Elizabeth Line At Stratford

I discuss this in Extending The Elizabeth Line – Connecting Great Eastern Main Line Services To The Central Tunnel.

 

 

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.

Do They Paint Their Own Toilets Like This?

I took these pictures in the toilet of a Thameslink train.

It is vandalism, pure and simple and those that did this should spend a long time in a suitable prison!

But then I hate graffiti and others might consider it art!

Nunhead Junction Improvement

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 Nunhead junction.

The report explains it like this.

Rail freight stakeholders have consistently highlighted Nunhead as a priority location for improving the flow of freight around the London orbital routes. The junction to the immediate east of the station is a flat crossing where two lines of route and multiple passenger and freight services groups converge into the South London Line, creating a pinch point for capacity.

Freight train drivers, when consulted for input into this strategy, flagged the route eastbound from Peckham Rye through Nunhead and towards Lewisham as a challenging section on which to keep heavier trains moving. This is primarily a consequence of the relatively slow permissible speed of 25mph over Nunhead Junction when routed towards Lewisham,
which follows a steadily rising gradient from Peckham Rye.

The option proposed by this strategy is for changes to the track alignment in order to increase the speed of the turnout towards Lewisham, as far as can be achieved without affecting the speed of the main route towards Catford. This option would primarily benefit the performance of eastbound freight flowing from the South London Line towards the North Kent lines, one of the key rail freight corridors in the South East, enabling freight trains to run at faster and more consistent speeds towards Lewisham.

This would most likely increase right time presentation at the critical flat junction at Lewisham, as well as assisting the flow of passenger and freight trains to the Catford Loop by ensuring preceding Lewisham-bound traffic can clear Nunhead Junction as quickly as possible.

Addressing the existing constraints to freight traffic through Nunhead, which by their nature most affect the heavier bulk traffic that characterises the North Kent corridor, would also support industry aspirations to maximise the payloads that trains can haul.

This map from cartometro.com shows the route between Nunhead and Lewisham stations.

 

And this Google Map shows Nunhead station and the junction.

Note.

  1. Nunhead junction is towards the right of the map.
  2. The lines going to the East go to Lewisham.
  3. The lines going to the South East go to Crofton Park and Catford.
  4. I have counted the freight trains through Nunhead junction on real time trains  and there can be as main as six trains per hour (tph), through the junction at times, using both Lewisham and Crofton Park routes.

But there would also appear to be plenty of space around the junction to realign the tracks.

As many trains need to go East from Lewisham and there are two flat junctions on the route; Nunhead and Lewisham, anything that improves keeping to schedule is to be welcomed.

The Use Of Electric Haulage

All routes through Nunhead junction have 750 VDC third-rail electrification, but I suspect all freight trains through the junction are diesel hauled.

Real time trains also shows that many of the trains through Nunhead junction also use the West London Line through Shepherd’s Bush.

In Decarbonisation Of London’s Freight Routes, I proposed a dual-voltage battery-electric locomotive to handle freight trains.

Perhaps more capable battery-electric freight locomotives with their better acceleration, are part of the solution at Nunhead junction.

Conclusion

This appears to be a well-thought out solution to one of the problems for freight trains in London.

I also believe that dual-voltage battery-electric locomotives could be part of the solution at Nunhead junction and would also help in many other places on the UK rail network.

Thoughts On Faster Trains On Thameslink

The Class 700 trains used by Thameslink only have an operating speed of 100 mph.

I do wonder, if that is a fast enough operating speed for all Thameslink routes.

Sharing The Midland Main Line With 125 mph Trains

A couple of years ago, I travelled back into St. Pancras with a group of East Midlands drivers in a Class 222 train.

They told me several things about the route including that the bridge at the South of Leicester station would be difficult to electrify, as it was low and the track couldn’t be lowered as one of Leicester’s main sewers was under the tracks at the bridge. Perhaps, this is one place, where discontinuous electrification could be used on the Midland Main Line.

They also told me, that sometimes the Thameslink trains were a nuisance, as because of their 100 mph operating speed, the 125 mph Class 222 trains had to slow to 100 mph.

Upgrading Of The Midland Main Line South Of Bedford

The electrification of the Midland Main Line South of Bedford is being updated, so that it is suitable for 125 mph running.

An Analysis Of Services On The Midland Main Line South Of Bedford

The current Class 222 trains are capable of 125 mph and will be replaced by Class 810 trains capable of the same speed on both diesel and electricity.

Currently, a Class 222 train is capable of doing the following on a typical non-stop run between St. Pancras and Leicester.

  • Covering the 30 miles between St. Albans and Bedford in 17 minutes at an average speed of 106 mph.
  • Covering the 50.3 miles between Bedford and Leicester in 30 minutes at an average speed of 100.6 mph.
  • Maintaining 125 mph for long stretches of the route, once the trains is North of London commuter traffic at St. Albans

I can estimate the timings on the 79.2 miles between Leicester and St. Albans, by assuming the train runs at a constant speed.

  • 100 mph – 47.5 minutes
  • 110 mph – 43.2 minutes
  • 125 mph – 38 minutes
  • 140 mph – 34 minutes

Note.

  1. I have done the calculation for 140 mph, as that is the maximum operating speed of the Class 810 train with full in-cab digital signalling.
  2. Trains have been running at 125 mph for a couple of decades on the Midland Main Line.
  3. To get a St. Pancras and Leicester time add another 14 minutes, which is the current time between St. Pancras and St. Albans of a Class 222 train.
  4. Some Off Peak trains are timed at 62-63 minutes between St. Pancras and Leicester.
  5. A time of under an hour between St. Pancras and Leicester might be possible and the Marketing Department would like it.
  6. As Thameslink trains between Bedford and St. Albans stop regularly, they are on the slow lines of the four-track railway, to the North of St. Albans.
  7. South of St. Albans, Thameslink trains often run on the fast lines.

I can expect that East Midlands Railway will want to be running their new Class 810 trains as far as far South as they can at 125 mph, to speed up their services. When the signalling allows it, they’ll want to run at 140 mph.

So they won’t want to see Thameslink’s slow trains on the fast lines.

  • But if you look at the Thameslink trains that do run on the fast lines between St. Albans and St. Pancras, they appear to be the four trains per hour (tph) that run to and from Bedford.
  • Of these trains, two tph terminate at Brighton and two tph terminate at Gatwick Airport.
  • The average speed of a Class 222 train between St. Albans and St. Pancras assuming 14 minutes for the 19.7 miles is 84.4 mph.

So it looks to me that a 100 mph Thameslink train could be able to get away without slowing the East Midland Railway expresses.

But then that is not surprising, as for many years, the Class 222 trains worked happily with 100 mph Class 319 trains.

Is There Scope For Extra And Faster Services Into St. Pancras?

I have only done a simple calculation, but I do wonder if there is scope for the following.

  • Increasing the frequency of trains for both Thameslink and East Midlands Railway.
  • Saving a few minutes on East Midlands Railway services.

Consider.

  • The new Class 810 electric trains will probably have better acceleration and deceleration than the current Class 222 diesel trains, when working using electric power.
  • East Midlands Railway is introducing Class 360 trains that were built as 100 mph trains by Siemens, who are now upgrading them to 110 mph trains.
  • Can Siemens do the same for the Class 700 trains and create a sub-fleet capable of 110 mph running?
  • All trains will be running under full in-cab digital signalling with a large degree of automatic train control.

I feel that if the Class 700 trains had the extra speed, they would make the planning of services South of St. Albans easier and allow the Class 810 trains to both run faster and provide more services.

Sharing The East Coast Main Line With 125 mph Trains

The following Thameslink services run up the East Coast Main Line past Stevenage.

  • Cambridge And Brighton – Two tph – Stops at Royston, Ashwell and Morden (1 tph), Baldock, Letchworth Garden City, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Gatwick Airport, Three Bridges, Balcombe, Haywards Heath and Burgess Hill
  • Cambridge and Kings Cross – Two tph – Stops at Foxton, Shepreth, Meldreth, Royston, Ashwell and Morden, Baldock, Letchworth Garden City, Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
  • Peterborough and Horsham – Two tph – Stops at Huntingdon, St Neots, Sandy, Biggleswade, Arlesey, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Coulsdon South, Merstham, Redhill, Horley, Gatwick Airport, Three Bridges, Crawley, Ifield, Faygate (limited) and Littlehaven

Note.

  1. Services are generally run by Class 700 trains, although lately the Kings Cross service seems to use Class 387 trains, which have a maximum speed of 110 mph and a more comfortable interior with tables.
  2. It is intended that the Cambridge and Kings Cross service will be extended to Maidstone East by 2021.

In addition there are two Cambridge Express and Fen Line services.

  • Kings Cross and Ely – One tph – Stops at Cambridge and Cambridge North.
  • Kings Cross and King’s Lynn – One tph – Stops at Cambridge, Cambridge North, Waterbeach, Ely, Littleport, Downham Market and Watlington

Note.

  1. These services are generally run by Class 387 trains.
  2. Cambridge and King’s Cross is timetabled at around fifty minutes.

Adding all of this together means that slower services on the East Coast Main Line are comprised of the following in both directions.

  • Three tph – 110 mph – Class 387 trains
  • Four tph – 100 mph – Class 700 trains

These seven trains will have to be fitted in with the 125 mph trains running services on the East Coast Main Line, for LNER, Grand Central, Hull Trains and East Coast Trains.

There are also the following problems.

  • All trains must navigate the double-track section of the East Coast Main Line over the Digswell Viaduct and through Welwyn North station.
  • The King’s Cross and Cambridge service stops in Welwyn North station.
  • Full in-cab digital signalling is being installed on the East Coast Main Line, which could increase the speed of the expresses through the double-track section.

Could the introduction of the Class 387 trains on the Cambridge and King’s Cross service have been made, as it easier to fit in all the services if this one is run by a 110 mph train?

However, the full in-cab digital signalling with a degree of automatic train control could be the solution to this bottleneck on the East Coast Main Line.

  • Trains could be controlled automatically and with great precision between perhaps Hatfield and Stevenage.
  • Some expresses might be slowed to create gaps for the Cambridge and Peterborough services.
  • The Hertford Loop Line is also getting full in-cab digital signalling, so will some services be sent that way?

In Call For ETCS On King’s Lynn Route, I talked about a proposal to improve services on the Fen Line. This was my first three paragraphs.

The title of this post, is the same as that on an article in Edition 849 of Rail Magazine.

The article is based on this document on the Fen Line Users Aoociation web site, which is entitled Joint Response To Draft East Coast Main Line Route Study.

In addition to ETCS, which could improve capacity on the East Coast Main Line, they would also like to see journey time reductions using trains capable of running at 125 mph or faster on the King’s Lynn to Kings Cross route.

My scheduling experience tells me that a better solution will be found, if all resources are similar.

Hence the proposal to run 125 mph trains between King’s Cross and King’s Lynn and probably Ely as well, could be a very good and logical idea.

If the Class 700 trains were increased in speed to 110 mph, the trains through the double-track section of the East Coast Main Line would be.

  • One tph – 110 mph – Class 387 trains
  • Four tph – 110 mph – Class 700 trains
  • Two tph – 125 mph – New trains

Note.

  1. This would probably be an easier mix of trains to digest with the high speed services, through the double-track section.
  2. I like the idea of extending the Ely service to Norwich to give Thetford, Attleborough and Wymondham an improved service to London, Cambridge and Norwich.

The new trains would probably be a version of Hitachi’s Regional Battery Train.

  • It would need to be capable of 125 mph on the East Coast Main Line.
  • If the Ely service were to be extended to Norwich, this section would be on battery power.

There are certainly a lot of possibilities.

But as with on the Midland Main Line, it looks like for efficient operation, the operating speed of the Class 700 trains on the route needs to be increased to at least 110 mph.

Could Faster Class 700 trains Improve Services To Brighton?

These are the Thameslink services that serve Bedford, Cambridge and Peterborough, that I believe could be run more efficiently with trains capable of at running at speeds of at least 110 mph.

  • Bedford and Brighton – Two tph
  • Bedford and Gatwick Airport – Two tph
  • Cambridge and Brighton – Two tph
  • Cambridge and Maidstone East – Two tph
  • Peterborough and Horsham – Two tph

Note.

  1. I have assumed that the Cambridge and King’s Cross service has been extended to Maidstone East as planned.
  2. Eight tph serve Gatwick Airport.
  3. Four tph serve Brighton.

The Gatwick Express services have a frequency of two tph between London Victoria and Brighton calling at Gatwick Airport is already run by 110 mph Class 387 trains.

It would appear that if the Bedford, Cambridge and Peterborough were run by uprated 110 mph Class 700 trains, then this would mean that more 110 mph trains would be running to Gatwick and Brighton and this must surely improve the service to the South Coast.

But it’s not quite as simple as that, as the Cambridge and Maidstone East services will be run by eight-car trains and all the other services by twelve-car trains.

Conclusion

There would appear to be advantages in uprating some or possibly all of the Class 700 trains, so that they can run at 110 mph, as it will increase capacity on the Brighton Main Line, East Coast Main Line and Midland Main Line.

Will Hitachi Announce A High Speed Metro Train?

As the UK high speed rail network increases, we are seeing more services and proposed services, where local services are sharing tracks, where trains will be running at 125 mph or even more.

London Kings Cross And Cambridge/Kings Lynn

This Great Northern service is run by Class 387 trains.

  • Services run between London Kings Cross and King’s Lynn or Cambridge
  • The Class 387 trains have a maximum operating speed of 110 mph.
  • The route is fully electrified.
  • The trains generally use the fast lines on the East Coast Main Line, South of Hitchin.
  • Most trains on the fast lines on the East Coast Main Line are travelling at 125 mph.

When in the future full digital in-cab ERTMS signalling is implemented on the East Coast Main Line, speeds of up to 140 mph should be possible in some sections between London Kings Cross and Hitchin.

The Digswell Viaduct Problem

I also believe that digital signalling may be able to provide a solution to the twin-track bottleneck over the Digswell Viaduct.

Consider.

  • Airliners have been flown automatically and safely from airport to airport for perhaps four decades.
  • The Victoria Line in London, has been running automatically and safely at over twenty trains per hour (tph) for five decades. It is now running at over 30 tph.
  • I worked with engineers developing a high-frequency sequence control system for a complicated chemical plant in 1970.

We also can’t deny that computers are getting better and more capable.

For these reasons, I believe there could be an ERTMS-based solution to the problem of the Digswell Viaduct, which could be something like this.

  • All trains running on the two track section over the Digswell Viaduct and through Welwyn North station would be under computer control between Welwyn Garden City and Knebworth stations.
  • Fast trains would be slowed as appropriate to create spaces to allow the slow trains to pass through the section.
  • The train drivers would be monitoring the computer control, just as they do on the Victoria Line.

Much more complicated automated systems have been created in various applications.

The nearest rail application in the UK, is probably the application of digital signalling to London Underground’s Circle, District, Hammersmith & City and Metropolitan Lines.

This is known at the Four Lines Modernisation and it will be completed by 2023 and increase capacity by up to twenty-seven percent.

I don’t think it unreasonable to see the following maximum numbers of services running over the Digswell Viaduct by 2030 in both directions in every hour.

  • Sixteen fast trains
  • Four slow trains

That is one train every three minutes.

Currently, it appears to be about ten fast and two slow.

As someone, who doesn’t like to be on a platform, when a fast train goes through, I believe that some form of advanced safety measures should be installed at Welwyn North station.

It would appear that trains between London Kings Cross and King’s Lynn need to have this specification.

  • Ability to run at 125 mph on the East Coast Main Line
  • Ability to run at 140 mph on the East Coast Main Line, under control of full digital in-cab ERTMS signalling.

This speed increase could reduce the journey time between London Kings Cross and Cambridge to just over half-an-hour with London Kings Cross and King’s Lynn under ninety minutes.

The only new infrastructure needed would be improvements to the Fen Line to King’s Lynn to allow two tph, which I think is needed.

Speed improvements between Hitchin and Cambridge could also benefit timings.

London Kings Cross And Cambridge/Norwich

I believe there is a need for a high speed service between London Kings Cross and Norwich via Cambridge.

  • The Class 755 trains, that are capable of 100 mph take 82 minutes, between Cambridge and Norwich.
  • The electrification gap between Ely and Norwich is 54 miles.
  • Norwich station and South of Ely is fully electrified.
  • Greater Anglia’s Norwich and Cambridge service has been very successful.

With the growth of Cambridge and its incessant need for more space, housing and workers, a high speed train  between London Kings Cross and Norwich via Cambridge could tick a lot of boxes.

  • If hourly, it would double the frequency between Cambridge and Norwich until East-West Rail is completed.
  • All stations between Ely and Norwich get a direct London service.
  • Cambridge would have better links for commuting to the city.
  • Norwich would provide the quality premises, that Cambridge is finding hard to develop.
  • London Kings Cross and Cambridge would be just over half an hour apart.
  • If the current London Kings Cross and Ely service were to be extended to Norwich, no extra paths on the East Coast Main Line would be needed.
  • Trains could even split and join at Cambridge or Ely to give all stations a two tph service to London Kings Cross.
  • No new infrastructure would be required.

The Cambridge Cruiser would become the Cambridge High Speed Cruiser.

London Paddington And Bedwyn

This Great Western Railway service is run by Class 802 trains.

  • Services run between London Paddington and Bedwyn.
  • Services use the Great Western Main Line at speeds of up to 125 mph.
  • In the future if full digital in-cab ERTMS signalling is implemented, speeds of up to 140 mph could be possible on some sections between London Paddington and Reading.
  • The 13.3 miles between Newbury and Bedwyn is not electrified.

As the service would need to be able to run both ways between Newbury and Bedwyn, a capability to run upwards of perhaps thirty miles without electrification is needed. Currently, diesel power is used, but battery power would be better.

London Paddington And Oxford

This Great Western Railway service is run by Class 802 trains.

  • Services run between London Paddington and Oxford.
  • Services use the Great Western Main Line at speeds of up to 125 mph.
  • In the future if full digital in-cab ERTMS signalling is implemented, speeds of up to 140 mph could be possible on some sections between London Paddington and Didcot Parkway.
  • The 10.3 miles between Didcot Parkway and Oxford is not electrified.

As the service would need to be able to run both ways between Didcot Parkway and Oxford, a capability to run upwards of perhaps thirty miles without electrification is needed. Currently, diesel power is used, but battery power would be better.

Local And Regional Trains On Existing 125 mph Lines

In The UK, in addition to High Speed One and High Speed Two, we have the following lines, where speeds of 125 mph are possible.

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

Note.

  1. Long stretches of these routes allow speeds of up to 125 mph.
  2. Full digital in-cab ERTMS signalling is being installed on the East Coast Main Line to allow running up to 140 mph.
  3. Some of these routes have four tracks, with pairs of slow and fast lines, but there are sections with only two tracks.

It is likely, that by the end of the decade large sections of these four 125 mph lines will have been upgraded, to allow faster running.

If you have Hitachi and other trains thundering along at 140 mph, you don’t want dawdlers, at 100 mph or less, on the same tracks.

These are a few examples of slow trains, that use two-track sections of 125 nph lines.

  • East Midlands Railway – 1 tph – Leicester and Lincoln – Uses Midland Main Line
  • East Midlands Railway – 1 tph – Liverpool and Norwich – Uses Midland Main Line
  • East Midlands Railway – 2 tph – St. Pancras and Corby – Uses Midland Main Line
  • Great Western Railway – 1 tph – Cardiff and Portsmouth Harbour – Uses Great Western Main Line
  • Great Western Railway – 1 tph – Cardiff and Taunton – Uses Great Western Main Line
  • Northern – 1 tph – Manchester Airport and Cumbria – Uses West Coast Main Line
  • Northern – 1 tph – Newcastle and Morpeth – Uses East Coast Main Line
  • West Midlands Trains – Some services use West Coast Main Line.

Conflicts can probably be avoided by judicious train planning in some cases, but in some cases trains capable of 125 mph will be needed.

Southeastern Highspeed Services

Class 395 trains have been running Southeastern Highspeed local services since 2009.

  • Services run between London St. Pancras and Kent.
  • Services use Speed One at speeds of up to 140 mph.
  • These services are planned to be extended to Hastings and possibly Eastbourne.

The extension would need the ability to run on the Marshlink Line, which is an electrification gap of 25.4 miles, between Ashford and Ore.

Thameslink

Thameslink is a tricky problem.

These services run on the double-track section of the East Coast Main Line over the Digswell Viaduct.

  • 2 tph – Cambridge and Brighton – Fast train stopping at Hitchin, Stevenage and Finsbury Park.
  • 2 tph – Cambridge and Kings Cross – Slow train stopping at Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
  • 2 tph – Peterborough and Horsham – Fast train stopping at Hitchin, Stevenage and Finsbury Park.

Note.

  1. These services are run by Class 700 trains, that are only capable of 100 mph.
  2. The fast services take the fast lines South of the Digswell Viaduct.
  3. South of Finsbury Park, both fast services cross over to access the Canal Tunnel for St, Pancras station.
  4. I am fairly certain, that I have been on InterCity 125 trains running in excess of 100 mph in places between Finsbury Park and Stevenage.

It would appear that the slow Thameslink trains are slowing express services South of Stevenage.

As I indicated earlier, I think it is likely that the Kings Cross and King’s Lynn services will use 125 mph trains for various reasons, like London and Cambridge in under half an hour.

But if 125 mph trains are better for King’s Lynn services, then they would surely improve Thameslink and increase capacity between London and Stevenage.

Looking at average speeds and timings on the 25 miles between Stevenage and Finsbury Park gives the following.

  • 100 mph – 15 minutes
  • 110 mph – 14 minutes
  • 125 mph – 12 minutes
  • 140 mph – 11 minutes

The figures don’t appear to indicate large savings, but when you take into account that the four tph running the Thameslink services to Peterborough and Cambridge stop at Finsbury Park and Stevenage and have to get up to speed, I feel that the 100 mph Class 700 trains are a hindrance to more and faster trains on the Southern section of the East Coast Main Line.

It should be noted, that faster trains on these Thameslink services would probably have better acceleration and and would be able to execute faster stops at stations.

There is a similar less serious problem on the Midland Main Line branch of Thameslink, in that some Thameslink services use the fast lines.

A couple of years ago, I had a very interesting chat with a group of East Midlands Railway drivers. They felt that the 100 mph Thameslink and the 125 mph Class 222 trains were not a good mix.

The Midland Main Line services are also becoming more complicated, with the new EMR Electric services between St. Pancras and Corby, which will be run by 110 mph Class 360 trains.

Hitachi’s Three Trains With Batteries

Hitachi have so far announced three battery-electric trains. Two are based on battery packs being developed and built by Hyperdrive Innovation.

Hyperdrive Innovation

Looking at the Hyperdrive Innovation web site, I like what I see.

Hyperdrive Innovation provided the battery packs for JCB’s first electric excavator.

Note that JCB give a five-year warranty on the Hyperdrive batteries.

Hyperdrive have also been involved in the design of battery packs for aircraft push-back tractors.

The battery capacity for one of these is given as 172 kWh and it is able to supply 34 kW.

I was very surprised that Hitachi didn’t go back to Japan for their batteries, but after reading Hyperdrive’s web site about the JCB and Textron applications, there would appear to be good reasons to use Hyperdrive.

  • Hyperdrive have experience of large lithium ion batteries.
  • Hyperdrive have a design, develop and manufacture model.
  • They seem to able to develop solutions quickly and successfully.
  • Battery packs for the UK and Europe are made in Sunderland.
  • Hyperdrive are co-operating with Nissan, Warwick Manufacturing Group and Newcastle University.
  • They appear from the web site to be experts in the field of battery management, which is important in prolonging battery life.
  • Hyperdrive have a Taiwanese partner, who manufactures their battery packs for Taiwan and China.
  • I have done calculations based on the datasheet for their batteries and Hyperdrive’s energy density is up with the best

I suspect, that Hitachi also like the idea of a local supplier, as it could be helpful in the negotiation of innovative applications. Face-to-face discussions are easier, when you’re only thirty miles apart.

Hitachi Regional Battery Train

The first train to be announced was the Hitachi Regional Battery Train, which is described in this Hitachi infographic.

Note.

  1. It is only a 100 mph train.
  2. The batteries are to be designed and manufactured by Hyperdrive Innovation.
  3. It has a range of 56 miles on battery power.
  4. Any of Hitachi’s A Train family like Class 800, 802 or 385 train can be converted to a Regional Battery Train.

No orders have been announced yet.

But it would surely be very suitable for routes like.

  • London Paddington And Bedwyn
  • London Paddington And Oxford

It would also be very suitable for extensions to electrified suburban routes like.

  • London Bridge and Uckfield
  • London Waterloo and Salisbury
  • Manchester Airport and Windermere.
  • Newcastle and Carlisle

It would also be a very sound choice to extend electrified routes in Scotland, which are currently run by Class 385 trains.

Hitachi InterCity Tri-Mode Battery Train

The second train to be announced was the Hitachi InterCity Tri-Mode Battery Train, which is described in this Hitachi infographic.

Note.

  1. Only one engine is replaced by a battery.
  2. The batteries are to be designed and manufactured by Hyperdrive Innovation.
  3. Typically a five-car Class 800 or 802 train has three diesel engines and a nine-car train has five.
  4. These trains would obviously be capable of 125 mph on electrified main lines and 140 mph on lines fully equipped with digital in-cab ERTMS signalling.

Nothing is said about battery range away from electrification.

Routes currently run from London with a section without electrification at the other end include.

  • London Kings Cross And Harrogate – 18.3 miles
  • London Kings Cross And Hull – 36 miles
  • London Kings Cross And Lincoln – 16.5 miles
  • London Paddington And Bedwyn – 13.3 miles
  • London Paddington And Oxford – 10.3 miles

In the March 2021 Edition of Modern Railways, LNER are quoted as having aspirations to extend the Lincoln service to Cleethorpes.

  • With all energy developments in North Lincolnshire, this is probably a good idea.
  • Services could also call at Market Rasen and Grimsby.
  • Two trains per day, would probably be a minimum frequency.

But the trains would need to be able to run around 64 miles each way without electrification. Very large batteries and/or charging at Cleethorpes will be needed.

Class 803 Trains For East Coast Trains

East Coast Trains have ordered a fleet of five Class 803 trains.

  • These trains appear to be built for speed and fast acceleration.
  • They have no diesel engines, which must save weight and servicing costs.
  • But they will be fitted with batteries for emergency power to maintain onboard  train services in the event of overhead line failure.
  • They are planned to enter service in October 2021.

Given that Hyperdrive Innovation are developing traction batteries for the other two Hitachi battery trains, I would not be the least bit surprised if Hyperdrive were designing and building the batteries for the Class 803 trains.

  • Hyperdrive batteries are modular, so for a smaller battery you would use less modules.
  • If all coaches are wired for a diesel engine, then they can accept any power module like a battery or hydrogen pack, without expensive redesign.
  • I suspect too, that the battery packs for the Class 803 trains could be tested on an LNER Class 801 train.

LNER might also decide to replace the diesel engines on their Class 801 trains with an emergency battery pack, if it were more energy efficient and had a lighter weight.

Thoughts On The Design Of The Hyperdrive innovation Battery Packs

Consider.

  • Hitachi trains have a sophisticated computer system, which on start-up can determine the configuration of the train or whether it is more than one train running as a longer formation or even being hauled by a locomotive.
  • To convert a bi-mode Class 800 train to an all-electric Class 801 the diesel engines are removed. I suspect that the computer is also adjusted, but train formation may well be totally automatic and independent of the driver.
  • Hyperdrive Innovation’s battery seem to be based on a modular system, where typical modules have a capacity of 5 kWh, weighs 32 Kg and has a volume of 0.022 cu metres.
  • The wet mass of an MTU 16V 1600 R80L diesel engine commonly fitted to AT-300 trains of different types is 6750 Kg or nearly seven tonnes.
  • The diesel engine has a physical size of 1.5 x 1.25 x 0.845 metres, which is a volume of 1.6 cubic metres.
  • In How Much Power Is Needed To Run A Train At 125 mph?, I calculated that a five-car Class 801 electric train, needed 3.42 kWh per vehicle-mile to maintain 125 mph.
  • It is likely, than any design of battery pack, will handle the regenerative braking.

To my mind, the ideal solution would be a plug compatible battery pack, that the train’s computer thought was a diesel engine.

But then I have form in the area of plug-compatible electronics.

At the age of sixteen, for a vacation job, I worked in the Electronics Laboratory at Enfield Rolling Mills.

It was the early sixties and one of their tasks was at the time replacing electronic valve-based automation systems with new transistor-based systems.

The new equipment had to be compatible to that which it replaced, but as some were installed in dozens of places around the works, they had to be able to be plug-compatible, so that they could be quickly changed. Occasionally, the new ones suffered infant-mortality and the old equipment could just be plugged back in, if there wasn’t a spare of the new equipment.

So will Hyperdrive Innovation’s battery-packs have the same characteristics as the diesel engines that they replace?

  • Same instantaneous and continuous power output.
  • Both would fit the same mountings under the train.
  • Same control and electrical power connections.
  • Compatibility with the trains control computer.

I think they will as it will give several advantages.

  • The changeover between diesel engine and battery pack could be designed as a simple overnight operation.
  • Operators can mix-and-match the number of diesel engines and battery-packs to a given route.
  • As the lithium-ion cells making up the battery pack improve, battery capacity and performance can be increased.
  • If the computer, is well-programmed, it could reduce diesel usage and carbon-emissions.
  • Driver conversion from a standard train to one equipped with batteries, would surely be simplified.

As with the diesel engines, all battery packs could be substantially the same across all of Hitachi’s Class 80x trains.

What Size Of Battery Would Be Possible?

If Hyperdrive are producing a battery pack with the same volume as the diesel engine it replaced, I estimate that the battery would have a capacity defined by.

5 * 1.6 / 0.022 = 364 kWh

In an article in the October 2017 Edition of Modern Railways, which is entitled Celling England By The Pound, Ian Walmsley says this in relation to trains running on the Uckfield Branch, which is not very challenging.

A modern EMU needs between 3 and 5 kWh per vehicle mile for this sort of service.

As a figure of 3.42 kWh per vehicle-mile to maintain 125 mph, applies to a Class 801 train, I suspect that a figure of 3 kWh or less could apply to a five-car Class 800 train trundling at around 80-100 mph to Bedwyn, Cleethorpes or Oxford.

  • A one-battery five-car train would have a range of 24.3 miles
  • A two-battery five-car train would have a range of 48.6 miles
  • A three-battery five-car train would have a range of 72.9 miles

Note.

  1. Reducing the consumption to 2.5 kWh per vehicle-mile would give a range of 87.3 miles.
  2. Reducing the consumption to 2 kWh per vehicle-mile would give a range of 109.2 miles.
  3. Hitachi will be working to reduce the electricity consumption of the trains.
  4. There will also be losses at each station stop, as regenerative braking is not 100 % efficient.

But it does appear to me, that distances of the order of 60-70 miles would be possible on a lot of routes.

Bedwyn, Harrogate, Lincoln and Oxford may be possible without charging before the return trip.

Cleethorpes and Hull would need a battery charge before return.

A Specification For A High Speed Metro Train

I have called the proposed train a High Speed Metro Train, as it would run at up to 140 mph on an existing high speed line and then run a full or limited stopping service to the final destination.

These are a few thoughts.

Electrification

In some cases like London Kings Cross and King’s Lynn, the route is already electrified and batteries would only be needed for the following.

  • Handling regenerative braking.
  • Emergency  power in case of overhead line failure.
  • Train movements in depots.

But if the overhead wires on a branch line. are in need of replacement, why not remove them and use battery power? It might be the most affordable and least disruptive option to update the power supply on a route.

The trains would have to be able to run on both types of electrification in the UK.

  • 25 KVAC overhead.
  • 750 VDC third rail.

This dual-voltage capability would enable the extension of Southeastern Highspeed services.

Operating Speed

The trains must obviously be capable of running at the maximum operating speed on the routes they travel.

  • 125 mph on high speed lines, where this speed is possible.
  • 140 mph on high speed lines equipped with full digital in-cab ERTMS signalling, where this speed is possible.

The performance on battery power must be matched with the routes.

Hitachi have said, that their Regional Battery trains can run at up to 100 mph, which would probably be sufficient for most secondary routes in the UK and in line with modern diesel and electric multiple units.

Full Digital In-cab ERTMS Signalling

This will be essential and is already fitted to some of Hitachi’s trains.

Regenerative Braking To Batteries

Hitachi’s battery electric  trains will probably use regenerative braking to the batteries, as it is much more energy efficient.

It also means that when stopping at a station perhaps as much as 70-80% of the train’s kinetic energy can be captured in the batteries and used to accelerate the train.

In Kinetic Energy Of A Five-Car Class 801 Train, I showed that at 125 mph the energy of a full five-car train is just over 100 kWh, so batteries would not need to be unduly large.

Acceleration

This graph from Eversholt Rail, shows the acceleration and deceleration of a five-car Class 802 electric train.

As batteries are just a different source of electric power, I would think, that with respect to acceleration and deceleration, that the performance of a battery-electric version will be similar.

Although, it will only achieve 160 kph instead of the 200 kph of the electric train.

I estimate from this graph, that a battery-electric train would take around 220 seconds from starting to decelerate for a station to being back at 160 kph. If the train was stopped for around eighty seconds, a station stop would add five minutes to the journey time.

London Kings Cross And Cleethorpes

As an example consider a service between London Kings Cross and Cleethorpes.

  • The section without electrification between Newark and Cleethorpes is 64 miles.
  • There appear to be ambitions to increase the operating speed to 90 mph.
  • Local trains seem to travel at around 45 mph including stops.
  • A fast service between London Kings Cross and Cleethorpes would probably stop at Lincoln Central, Market Rasen and Grimsby Town.
  • In addition, local services stop at Collingham, Hykeham, Barnetby and Habrough.
  • London Kings Cross and Newark takes one hour and twenty minutes.
  • London Kings Cross and Cleethorpes takes three hours and fifteen minutes with a change at Doncaster.

I can now calculate a time between Kings Cross and Cleethorpes.

  • If a battery-electric train can average 70 mph between Newark and Cleethorpes, it would take 55 minutes.
  • Add five minutes for each of the three stops at Lincoln Central, Market Rasen and Grimsby Town
  • Add in the eighty minutes between London Kings Cross and Newark and that would be  two-and-a-half hours.

That would be very marketing friendly and a very good start.

Note.

  1. An average speed of 80 mph would save seven minutes.
  2. An average speed of 90 mph would save twelve minutes.
  3. I suspect that the current bi-modes would be slower by a few minutes as their acceleration is not as potent of that of an electric train.

I have a feeling London Kings Cross and Cleethorpes via Lincoln Central, Market Rasen and Grimsby Town, could be a very important service for LNER.

Interiors

I can see a new lightweight and more energy efficient interior being developed for these trains.

In addition some of the routes, where they could be used are popular with cyclists and the current Hitachi trains are not the best for bicycles.

Battery Charging

Range On Batteries

I have left this to last, as it depends on so many factors, including the route and the quality of the driving or the Automatic Train Control

Earlier, I estimated that a five-car train with all three diesel engines replaced by batteries, when trundling around Lincolnshire, Oxfordshire or Wiltshire could have range of up to 100 miles.

That sort of distance would be very useful and would include.

  • Ely and Norwich
  • Newark and Cleethorpes
  • Salisbury and Exeter

It might even allow a round trip between the East Coast Main Line and Hull.

The Ultimate Battery Train

This press release from Hitachi is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%.

This is a paragraph.

The projected improvements in battery technology – particularly in power output and charge – create opportunities to replace incrementally more diesel engines on long distance trains. With the ambition to create a fully electric-battery intercity train – that can travel the full journey between London and Penzance – by the late 2040s, in line with the UK’s 2050 net zero emissions target.

Consider.

  • Three batteries would on my calculations give a hundred mile range.
  • Would a train with no diesel engines mean that fuel tanks, radiators and other gubbins could be removed and more or large batteries could be added.
  • Could smaller batteries be added to the two driving cars?
  • By 2030, let alone 2040, battery energy density will have increased.

I suspect that one way or another these trains could have a range on battery power of between 130 and 140 miles.

This would certainly be handy in Scotland for the two routes to the North.

  • Haymarket and Aberdeen, which is 130 miles without electrification.
  • Stirling and Inverness, which is 111 miles without electrification, if the current wires are extended from Stirling to Perth, which is being considered by the Scottish Government.

The various sections of the London Paddington to Penzance route are as follows.

  • Paddington and Newbury – 53 miles – electrified
  • Newbury and Taunton – 90 miles – not electrified
  • Taunton and Exeter – 31 miles – not electrified
  • Exeter and Plymouth – 52 miles – not electrified
  • Plymouth and Penzance – 79 miles – not electrified

The total length of the section without electrification between Penzance and Newbury  is a distance of 252 miles.

This means that the train will need a battery charge en route.

I think there are three possibilities.

  • Trains can take up to seven minutes for a stop at Plymouth. As London and Plymouth trains will need to recharge at Plymouth before returning to London, Plymouth station could be fitted with comprehensive recharge facilities for all trains passing through. Perhaps the ideal solution would be to electrify all lines and platforms at Plymouth.
  • Between Taunton and Exeter, the rail line runs alongside the M5 motorway. This would surely be an ideal section to electrify, as it would enable battery electric trains to run between Exeter and both Newbury and Bristol.
  • As some trains terminate at Exeter, there would probably need to be charging facilities there.

I believe that the date of the late 2040s is being overly pessimistic.

I suspect that by 2040 we’ll be seeing trains between London and Aberdeen, Inverness and Penzance doing the trips without a drop of diesel.

But Hitachi are making a promise of London and Penzance by zero-carbon trains, by the late-2040s, because they know they can keep it.

And Passengers and the Government won’t mind the trains being early!

Conclusion

This could be a very useful train to add to Hitachi’s product line.
