The Anonymous Widower

Tender Set To Be Issued For East West Rail Rolling Stock

The title of the this post is the same as that of this article on Rail Magazine.

Brief details of the fleet include.

  • Eleven trains.
  • Self-propelled.
  • Three cars.

Services are due to commence in 2024, serving Oxford, Aylesbury, Milton Keynes and Bedford.

Here are a few of my thoughts.

Are Three Car Trains Long Enough?

New train services in the UK, especially those on new or reopened routes, seem to suffer from London Overground Syndrome.

I define it as follows.

This benign disease, which is probably a modern version of the Victorian railway mania, was first identified in East London in 2011, when it was found that the newly-refurbished East London Line and North London Line were inadequate due to high passenger satisfaction and much increased usage. It has now spread across other parts of the capital, despite various eradication programs.

The Borders Railway certainly suffered and the London Overground is still adding extra services on the original routes.

Three-car trains may be enough for the initial service, but provision must be made  for running longer trains.

  • The trains that are purchased must be capable of lengthening.
  • Platforms must be built for longer trains.

So often we don’t future-proof new rail routes.

What Performance Is Needed?

I’ll ask this question first, as it may affect the choice of train.

The trains will certainly be at least capable of 100 mph operation.

But I wouldn’t be surprised if they were capable of 110 mph or even 125 mph, as this would surely make it easier for trains to go walkabout on the Great Western, Midland and West Coast Main Lines.

Faster East West trains might also get more services out of the fleet.

Appropriate acceleration and braking would be needed.

Conservative Or Innovative?

Will we get more of the same or will some of the responders to the tender offer trains based on innovative designs?

I would hope that as the line will eventually connect Oxford and Cambridge via Milton Keynes, the trains will take over the flavour of the route and be more innovative.

The Route

The eventual full route of the East West Rail Link will serve these sections.

  • Reading and Ocford – 25 miles – Partially-electrified
  • Oxford and Milton Keynes – 43 miles – Not electrified
  • Milton Keynes and Bedford – 20 miles – Partially-electrified
  • Bedford and Sandy – 10 miles – Not electrified
  • Sandy and Cambridge – 25 miles – Partially-electrified.

Note.

  1. The distances are approximate.
  2. With the exception of Oxford, all the major stations will be served by electric trains on other routes.

It is rather a mixture created out of existing and abandoned routes.

Could Battery Trains Run On The East West Rail Link?

Consider.

  • All the major stations except Oxford have electrification.
  • Sections of the route are electrified.
  • The route is not very challenging.
  • The longest section without electrification is around forty miles.

All this leads me to believe that a battery-electric train with a range of forty miles could handle the route, if there was the means to charge the train at Oxford.

Possibly the easiest way to achieve the charging station at Oxford station, would be to electrify between Didcot Junction and Oxford stations.

In How Much Power Is Needed To Run A Train At 125 mph?, I showed that to run at 125 mph, a train needs around three kWh per vehicle mile.

This would mean that to run between Oxford and Milron Keynes stations, would need a maximum power of around 40*3*3 kWh or 360 kWh.

This is only a 120 kWh battery in each car.

I am fairly certain, that a well-designed battery train could run on the East West Rail Link.

The Usual Suspects

There are several train companies, who could be offering existing trains or their developments.

Alstom

Alstom don’t have a current design of train for the UK, but they are heavily into the development of trains powered by hydrogen.

By 2024, I suspect they will be offering a purpose-built hydrogen-powered train for the UK.

Also, by that time, I think it will be likely, that many buses in cities will be powered by zero-carbon hydrogen and the availability of this fuel would be much better than it is today.

An East West Rail Link running hydrogen-powered trains would go a long way to answer the electrification lobby.

Bombardier

Bombardier are developing a 125 mph bi-mode Aventra with batteries, that they are proposing for various franchises in the UK, including the Midland Main Line.

I believe that by rearranging the components of this train, they could develop a train that would be very suitable for the East West Rail Link.

  • Three cars
  • At least 100 mph operating speed
  • In service by 2024 or earlier.

It could be a bi-mode train with batteries, or if battery and the associated charging technology has improved, it could be a battery-electric train.

The latter would certainly fulfil the flavour of the route.

Bombardier’s Aventra would also have the advantages of an electrical version and the ability to add more cars.

CAF

CAF have recently introduced the Class 195 traincaf in the UK.

But would a diesel train be acceptable on a flagship route?

On the other hand CAF have been delivering battery-powered trams for several years and I wouldn’t be surprised to see the company, offer an innovative battery-electric train for the East West Rail Link.

Hitachi

Hitachi don’t make self-powered trains in the UK.

But in Hitachi Plans To Run ScotRail Class 385 EMUs Beyond The Wires, I wrote about the company’s plans to use batteries as range extenders on their Class 385 trains.

I suspect that by 2024, these trains will be running in Scotland and they will probably be high-quality reliable trains.

So could these trains be able to run between Reading and Cambridge using battery power, topped up at the various sections of electrification along the route.

Hitachi’s development regime is cautious, professional and well-funded, so I suspect they could offer a version of the Class 385 train, for delivery in 2024.

Hitachi would also have the advantages of an electrical version and the ability to add more cars.

Siemens

Siemens have a large number of modern electrical multiple units in the UK, but none are self-powered, except the diesel Class 185 train.

Siemens will have a factory in the UK to built London Underground trains by 2024.

But eleven trains could be an expensive order to fulfil, if it required a new self-powered train design.

Stadler

Stadler are an innovative company and their Class 755 train will shortly be starting passenger service in East Anglia.

  • It is three-cars, which is extendable if required.
  • It has a 100 mph operating speed.
  • It is a bi-mode; diesel and electric train.
  • Trains for Wales have ordered a diesel/electric/battery version.
  • There are rumours of hydrogen-powered versions.

Stadler could certainly deliver some of these trains by 2024.

Summing Up

I would suspect that the front runners are Bombardier, Hitachi and Stadler, with CAF in fourth place.

  • All could probably develop a zero-emission train for the route using battery technology.
  • Stadler will have trains in service this year, and I suspect Bombardier and Hitachi will be running trains by 2022.

I think we could be seeing some very good trains on the route.

Hitachi Plans To Run ScotRail Class 385 EMUs Beyond The Wires

The title of this post is the same as that of this article on Rail Engineer.

This is the first paragraph.

Hitachi are in discussions with the Scottish Government to run a Class 385 variant with underfloor batteries that could either be charged whilst under the wires or whilst stationary at the end of the route.

The article makes these points, about adding batteries to Class 385 trains.

  • It would be straightforward to add batteries to give a range of twenty miles on batteries.
  • Sixty miles would be possible but more difficult.
  • Experience gained with the DENCHA trains in Japan would be used.

The article concludes with this paragraph.

Hitachi’s proposal to operate battery trains in Scotland is at an early stage. However, with their use being recommended by the rail decarbonisation task force and the Scottish Government about to pass new climate change legislation, it may not be long before battery trains are operating in Scotland.

I think it should be noted that Hitachi’s order book is rather thin these days and it appears that innovative technology will sell new trains.

Alstom, Bombardier, CAF, Siemens, Stadler and Vivarail have all designed, demonstrated or sold trains, where batteries are used improve efficiency or extend range.

As Scotland has several routes, where battery trains could provide a service, perhaps Hitachi thought it was time to do some marketing, to make sure that they got any orders for battery trains.

Scotrail would probably prefer to have a battery train similar to their largest fleet of electric trains.

Electric Trains On The West Highland Line Between Glasgow And Mallaig/Oban

This might be considered as difficult as putting a London bus on the Moon.

But consider.

  • The West Highland Line is electrified as far as Helensburgh Central station.
  • Electrification to Helensburgh Upper station would probably not be a difficult project for Network Rail in Scotland.
  • Heleburgh Upper to Mallaig is just under 140 miles.
  • Hellensuburgh Upper to Oban is around 76 miles.
  • Crianlarich station, where the two routes divide is under forty miles from Helensburgh Upper.
  • Fort William station is around halfway between Mallaig and Crianlarich.
  • Trains take several minutes to reverse at Fort William.

Vivarail have developed fast charging for battery trains, that I wrote about in Vivarail Unveils Fast Charging System For Class 230 Battery Trains.

If Hitachi can develop a Class 385 train with batteries, that has a range of perhaps sixty miles on a full battery, then I believe it would be possible to run an electric train service between Glasgow and Oban and Mallaig.

  • Charging stations would need to be able to fully charge the batteries in perhaps six minutes.
  • Trains would leave Hellensburgh Upper with a full battery and charging stations at Crianlarich and Fort William would top up the batteries.
  • The longest stretch is between Crianlarich and Fort William and it would probably need an additional charging station at perhaps Tulluch.

What would battery-electric trains to Oban and Mallaig do for tourism in the area?

Hitachi would have one of the most scenic and iconic test tracks in the world!

£18.75m Halton Curve Project Delayed A Further Six Months

The title of this post is the same as that of this article on Rail Technology News.

I could just blame politicians for the latest project to be delayed, but it is not wholly their fault.

Train companies all over the UK, Europe and the Rest of the World have been ordering new trains at an unprecedented rate for the following reasons.

  • The replacement of clapped-out trains like Pacers.
  • Extra trains to provide extra services.
  • Faster trains to provide faster services.
  • Bigger or longer trains to provide more capacity.
  • New electric trains for newly electrified routes.
  • New trains often cost less to service and maintain.
  • Affordable finance for quality new trains is available in billions of pounds, euros and dollars of all kinds.

In addition a lot of trains are being updated with new technology like signalling, automatic systems and high-technology interiors.

All of these factors mean that there is a high level of train testing that needs to be done.

These test tracks are in Europe and listed in Wikipedia.

Note that Italy and Soain, who build substantial numbers of trains, don’t have a specialist testing centre.

I have read somewhere that each individual train has to be run for so many hours before it can be certified for service.

Consider

  • Bombardier is building 412 Aventras with lengths between three and ten cars.
  • CAF is building trains for Calodonian Sleeper, Keolis Amey Wales, Northern, TranPennine Express and West Midlands Trains.
  • Hitachi is building 182 Class 800/801/802 trains with length of five or nine cars.
  • Hitachi is building 80 Class 385 trains with lengths of 3/4 cars.
  • Siemens are building trains for Govia Thameslink Railway.
  • Stadler is building trains for Greater Anglia, Keolis Amay Wales and MerseyRail.

I haven’t done a detailed calculation must it must be at least 700 trains.

In addition there are various rebuilt and existing trains that will need to be tested.

  • ScotRail’s shorterned InterCity 125s
  • Porterbrook’s Class 769 trains.
  • Vivarail’s Class 230 trains.
  • Alstom’s Class 321 Hydrogen trains.
  • Crossrail Class 345 trains need further testing.

And there will be new orders for the following franchises and lines.

  • East Midlands.
  • London Underground Piccadilly Line.
  • South Eastern
  • West Coast Alliance

I haven’t done a detailed calculation but we must be talking of nearly a thousand new trains of which probably six hundred will be delivered in the next five years.

I’m no expert, but I feel that two short test tracks and short lengths of improvised test tracks in factories, isn’t enough to test all these trains and certify them for service.

I should also blow my own trumpet and I know that when I wrote project management software, I was probably the best programmer in the World, at automatically scheduling resources.

So I tend to know, an impossible scheduling problem, when I see one!

Conclusion

We do send trains to Europe to specialist centres like the one at Velim in the Czech Republic. But these centres are also used by other European manufacturers.

I am led to the inevitable conclusion, that we need more train testing facilities, in both the UK and mainland Europe.

The Welsh Government has come to the same conclusion and are planning a test track at Neath, which I wrote about in £100m Rail Test Complex Plans For Neath Valley.

What would help, would be if Chris Grayling oiled a few wheels with some money. It might even result in some Continental trains coming to Wales for specialist testing like curing them of dracophobia.

I would also have felt that CAF would be happy with a test track fifty miles away from their new factory in Newport.

Come on, Wales! Fire up the dragons and get started!

Bidders For New Tyne And Wear Metro Fleet Revealed

The title of this post is the same as that of this article on Global Rail News.

The approved bidders are.

I am sure all will be good bids, but there are various factors that must be taken into account.

Current Rolling Stock

The current rolling stock has a slightly smaller cross section than most of the UK.

Although, some lines are shared with other trains like Grand Central’s InterCity 125s.

As new and old rolling stock will probably have to work together, they’ll probably need to be a similar size.

Modern manufacturing should handle that with ease.

Dual Voltage

I suspect that new route opportunities for the Metro will involve excursions on lines with 25 KVAC overhead electrification.

I doubt this is a problem these days.

Battery Power

Some new routes would be ideal for battery power.

As with dual voltage, this should not be a problem.

UK Experience

All bidders except for the Australian/Chinese joint venture of Downer EDI/CRRC have made significant sales in the UK.

Stadler is the interesting company, as they seem to be able to design bespoke trains for the local area, that seem to win bids.

  • Class 399 tram-trains for the tram-train trial in Sheffield.
  • Class 745 and Class 755 trains for Greater Anglia.
  • Class 777 trains for Merseyrail.
  • Citylink tram-trains and diesel/electric/battery tri-mode Flirts for the South Wales Metro.
  • Trains for the Glasgow Subway.

Stadler seem to have a library of standard solutions, that allows them to create smaller fleets to a slightly non-standard specification.

UK Manufacturing

All companies except Downer EDI/CRRC and Stadler have UK factories.

I can’t see the Australian/Chinese joint venture building a factory in the UK for a £362 million contract for one order in the North East, even though CRRC would probably like to get more involved in the UK rolling stock market.

Stadler has an unusual manufacturing model, in that trains and bodies are built in factories in various parts of Europe and sometimes brought to Switzerland for final assembly and testing.

I wouldn’t be surprised to see Stadler setting up a UK operation to support their increasing UK presence and perhaps do the interior fitting out for future orders.

As to Stadler, I think it should be noted, that with the exception of the Glasgow Subway trains, I suspect all their UK trains are capable of being towed on much of the UK rail network.

Brexit may also give Stadler, an opportunity to set up a factory outside the EU, but connected to it, by the Channel Tunnel.

Conclusion

As I said earlier, all bids will have a high quality and reasons for winning.

However, I do feel that the Downer EDI/CRRC bid may be discounted for reasons of geography and politics.

I also think we should be prepared for Stadler to offer an innovative bid similar to the ones that succeeded on Merseyside and in South Wales.

Class 365 Trains To The Rescue

I had intended to get a ride on a new Class 385 train, but I only caught a glimpse of one going the other way, from a Class 365 train, that I used both ways between Edinburgh and Glasgow.

Passengers seemed to be quite happy with the Class 365 trains cascaded from the Cambridge Cruiser.

I really think that Hitachi have got their production of the Class 385 trains, seriously wrong here.

The body shells are made in Japan and then sent to Newton Aycliffe by sea. This must be an easy way to ensure a slow production of trains.

Bombardier make the body shells in the same factory as they design and assemble the trains.

Even if CAF make their body shells in Spain, that is a much shorter and probably more reliable journey.

I must admit if I was the CEO of a train operating company, I wouldn’t buy a Hitachi train.

But then Tony Blair only wanted a new factory, close to his constituency!

Retrofitted Hydrogen Fuel Cell EMU Concept Presented

The title of this post is the same as that of this article on Global Rail News, that was published in April 2014.

This is the first two paragraphs.

The possibility of retro-fitting diesel multiple units (DMUs) to run on hydrogen fuel cell technology has been put to the test as part of an RSSB and Network Rail-funded innovation research programme.

Fuel Cell Systems, which has worked alongside the University of Birmingham and Hitachi Rail Europe, says the six-month study has demonstrated the feasibility of installing hydrogen fuel cell technology on DMUs as an alternative to electrification.

It strikes me that some serious people are involved in this project.

The report on the project was published in June 2016 and it is stored here on the University pf Birmingham web site.

Hitachi Ships TransPennine Express’s First Class 802 From Japan

The title of this post is the same as that of this article on Global Rail News.

To my mind, the Japanese do some inefficient things when building trains.

  • It could be sensible to build the first of each different sub-fleet in Japan and ship it to the UK by sea, but what puzzles me is that the body shells are all built and painted in Japan and then shipped half-way round the world.
  • The shipping delay must make production difficult to plan and inefficient.
  • I would have thought they would have built a body plant somewhere in Europe.

CAF may send their trains by ship, but that is only a short sea crossing and because the Spanish rail gauge they can’t tow them through the Channel Tunnel, as the other European manufacturers do.

Hitachi’s Thoughts On Battery Trains

On page 79 of the January 2018 Edition of Modern Railways, Nick Hughes, who is the Sales Director of Hitachi Rail Europe outlines how the manufacturer is embracing the development of battery technology.

He is remarkably open.

Hitachi’s Battery Development

Nick Hughes says this.

Hitachi has for many years seen great potential in battery technology.

We began studying on train storage energy systems in 2003. Working jointly qith operational partners in Japan and in the UK, we developed a realistic solution based on a lithium-ion battery, that could store the braking energy and reuse it for the traction.

Then came our V-train 2 (nicknamed the Hayabusa), which was tested on the Great Central Railway in 2007, using hybrid battery/diesel power and regenerative charging. This was the world’s first high-speed hybrid train.

This picture show the Hayabusa running in the UK.

If you think it looks familiar, you are right! It’s a modified Class 43 locomotive from an InterCity 125. The locomotive; 43089, is still in service with East Midlands Trains. But without the batteries!

When the remaining members of the  team, who had developed the InterCity 125 in the 1970s, saw these pictures, I suspect it was celebrated with a call for a few swift halves!

BEMU In Japan

Nick Hughes goes on to outline the status of Battery Electric Multiple Units (BEMUs) in Japan, where Hitachi launched a train called the DENCHA  in 2016, on the Chikuhi line.

  • The train has a range of up to 50 km on batteries.
  • DENCHA is popular with passengers.
  • The train won a prestigious award.

I don’t know what it is with battery trains, but the Bombardier/Network Rail BEMU Trial was also liked by those who rode the train. As was I!

Nick Hughes Prediction

Nick Hughes follows his description of the DENCHA, with this.

I can picture a future when these sorts of trains are carrying out similar types of journeys in the UK, perhaps by installing battery technology in our Class 395s to connect to Hastings via the non-electrified Marshlink Line from Ashford for example.

This would massively slice the journey time and heklp overcome the issue of electrification and infrastructure cases not stacking up. There are a large number of similar routes like this all across the country.

It is a prediction, with which I could agree.

Renewable Energy And Automotive Systems

Nick Hughes finishied by saying that he believes storing power from renewable energy and the development of automotive systems will drive battery technology and its use.

Conclusion

It is the most positive article about battery trains, that I have read so far!

Hybrid Trains Proposed To Ease HS1 Capacity Issues

The title of this post is the same as an article in Issue 840 of Rail Magazine.

This is the first paragraph.

Battery-powered hybrid trains could be running on High Speed 1, offering a solution to capacity problems and giving the Marshlink route a direct connection to London.

Hitachi Rail Europe CEO Jack Commandeur is quoted as saying.

We see benefit for a battery hybrid train, that is being developed in Japan, so that is an option for the electrification problem.

I found this article on the Hitachi web site, which is entitled Energy-Saving Hybrid Propulsion System Using Storage–Battery Technology.

It is certainly an article worth reading.

This is an extract.

Hitachi has developed this hybrid propulsion system jointly with East Japan Railway Company (JR-East) for the application to next-generation diesel cars. Hitachi and JR-East have carried out the performance trials of the experimental vehicles with this hybrid propulsion system, which is known as NE@train.
Based on the successful results of this performance trial, Ki-Ha E200 type vehicle entered into the world’s first commercial operation of a train installed with the hybrid propulsion system in July 2007.

The trains are running on the Koumi Line in Japan. This is Wikipedia’s description of the line.

Some of the stations along the Koumi Line are among the highest in Japan, with Nobeyama Station reaching 1,345 meters above sea level. Because of the frequent stops and winding route the full 78.9 kilometre journey often takes as long as two and a half hours to traverse, however the journey is well known for its beautiful scenery.

The engineers, who chose this line for a trial of battery trains had obviously heard Barnes Wallis‘s quote.

There is no greater thrill in life than proving something is impossible and then showing how it can be done.

But then all good engineers love a challenge.

In some ways the attitude of the Japanese engineers is mirrored by those at Porterbrook and Northern, who decided that the Class 769 train, should be able to handle Northern’s stiffest line, which is the Buxton Line. But Buxton is nowhere near 1,345 metres above sea level.

The KiHa E200 train used on the Koumi Line are described like this in Wikipedia.

The KiHa E200 is a single-car hybrid diesel multiple unit (DMU) train type operated by East Japan Railway Company (JR East) on the Koumi Line in Japan. Three cars were delivered in April 2007, entering revenue service from 31 July 2007.

Note that the railway company involved is JR East, who have recently been involved in bidding for rail franchises in the UK and are often paired with Abellio.

The Wikipedia entry for the train has a section called Hybrid Operation Cycle. This is said.

On starting from standstill, energy stored in lithium-ion batteries is used to drive the motors, with the engine cut out. The engine then cuts in for further acceleration and running on gradients. When running down gradients, the motor acts as a generator, recharging the batteries. The engine is also used for braking.

I think that Hitachi can probably feel confident that they can build a train, that can handle the following.

  • High Speed One on 25 KVAC overhead electrification.
  • Ore to Hastings on 750 VDC third-rail electrification.
  • The Marshlink Line on stored energy in lithium-ion batteries.

The Marshlink Line has a big advantage as a trial line for battery trains.

Most proposals say that services will call at Rye, which is conveniently around halfway along the part of the route without electrification.

I believe that it would be possible to put third-rail electrification in Rye station, that could be used to charge the batteries, when the train is in the station.

The power would only be switched on, when a train is stopped in the station, which should deal with any third-rail safety problems.

Effectively, the battery-powered leg would be split into two shorter ones.

First Steps To Faster Trains Is Delivered

This is the title of an article in the Hastings and St. Leonards Observer, that has been signed by Amber Rudd.

About Amber Rudd

Amber Rudd is the Home Secretary and in this year’s General Election, she retained the Hastings and Rye constituency with a majority of just 346 votes.

As I doubt she wants to commit political suicide, I therefor consider that what is said in the article is very close to what is intended to happen about the delivery of faster trains between London and Hastings.

London To Hastings In 66 Minutes

This is the first two paragraphs of her article.

Last week I invited Transport Secretary Chris Grayling to visit Ashford International to hear an update on my campaign to secure a high speed rail link between our communities and London St Pancras.

Specifically, I want to see journey times, which are currently around 100 minutes between Hastings and London, reduced to 66 minutes.

The sixty-six minutes is mentioned again later in the article.

Would a politician be so definite about her aims, unless she knew that it was deliverable?

Or is it lucky to say sixty-six in Hastings?

So how feasible is London to Hastings in 66 minutes?

Consider.

  • Southeastern’s Highspeed services between St. Pancras and Ashford, generally take between 37-38 minutes for the journey, with some trains a few minutes faster.
  • The Marshlink Line between Ashford and Hastings is about 26¼ miles in length
  • The operating speed is quoted in Wikipedia as 60 mph.
  • There are some serious level crossings.

So could a train go from Ashford to Hastings in twenty-eight minutes to meet Amber Rudd’s quoted target of 66 minutes?

26¼ miles in 28 minutes works out a an average speed of 56.25 mph.

I would give that time a 9/10 for feasibility.

The problem would be the level crossings on the line, so if Network Rail were to remove these and improve the track a bit, I feel that this could even score highly for reliability.

Currently, there doesn’t appear to be many trains passing through and even if the service was doubled to two trains per hour in both directions, I don’t think they would trouble the timetable compiler.

Track Changes At Ashford

Amber Rudd’s article then says this about track changes at Ashford.

This was a very encouraging meeting. I am pleased to announce that the commitment has been made to supporting the development of a proposed track layout at Ashford International which would allow trains from Hastings, Rye, Bexhill and Eastbourne to travel direct to London St Pancras

Work will now begin towards the necessary track connections to join-up the Marshlink and the High Speed 1 line to London.

This change would help make possible the direct service to St Pancras with a journey time of 81 minutes from Hastings.

That seems to be a plan. But where does the 81 minutes come from?

The current Class 171 trains take around 42 minutes between Hastings and Ashford, so 38+42 would say that 81 minutes is a reasonable claim.

This document on the Network Rail web site, is the Technical Appendix of the South East Route: Kent Area Route Study.

This map was extracted from the document.

This shows the changes needed to connect HS1 to the Marshlink Line.

Diesel-Electric Or Battery-Electric Trains?

Amber Rudd’s article says this about the trains.

Accompanying the track changes at Ashford, hybrid rolling stock – trains running on diesel-electric or battery-electric power – would make these quick journey times a reality.

This fits in with what is said in the Technical Appendix to the  Kent Area Route Study.

The diesel electric train mentioned in the Technical Appendix is a Class 802 train. Production and delivery of these is underway for Great Western Railway, so we’re not talking about an untried class of train.

But there may be problems running trains carrying diesel fuel in the HS1 tunnels.

The battery-electric train mentioned in the Technical Appendix is the IPEMU based on a Class 379 train.

This train is not in production yet and the picture shows the test train, that ran in Essex nearly two years ago.

The Technical Appendix says this about the IPEMU.

In 2015, industry partners worked together to investigate
battery-electric traction and this culminated with a
practical demonstration of the Independently Powered
Electric Multiple Unit IPEMU concept on the Harwich
Branch line in Anglia Route. At the industry launch event,
the train manufacturers explained that battery
technology is being developed to enable trains to run
further, at line speeds, on battery power, indeed, some
tram lines use this technology in the city centres and many
London buses are completely electric powered.

The IPEMU project looked at the feasibility of battery power
on the Marshlink service and found that battery was
sufficient for the train to run from Brighton to Ashford
International and back but there was insufficient charge to
return to Ashford International on a second round trip. A
solution to this could be that the unit arrives from Ashford
International at Brighton and forms a service to Seaford and
back before returning to Ashford International with a
charged battery.

The IPEMU demonstration train was a Class 379, a similar
type to the Class 377 units currently operated by Southern, it
was found that the best use of the battery power was to
restrict the acceleration rate to that of a modern diesel
multiple unit, such as a Class 171 (the current unit type
operating the line) when in battery mode and normal
acceleration on electrified lines.

Note the following from Network Rail’s text.

  • Brighton to Ashford is about 60-70 miles.
  • Acceleration should be limited.
  • The Class 377 train would not be suitable for HS1, as it is only a 100 mph train.

It is my opinion, that a battery-electric train with the following characteristics could be designed.

  • Five to eight cars.
  • 140 mph on HS1 using 25 KVAC overhead electrification.
  • 100 mph on the East Coastway Line between Brighton and Hastings using 750 VDC third-rail electrification.
  • Class 171 train performance using batteries on the Marshlink Line.
  • A battery range of sixty miles to allow a fully charged train to go from Ashford to Hastings and back.

Effectively, it’s a dual-voltage high speed train, that can also run on battery power.

How Would A Battery Train Operate?

A train working from St. Pancras to Hastings would go through the following operations.

  • Run from St. Pancras to Ashford along HS1, as the current Class 395 trains do using the 25KVAC overhead power.
  • Stop in Platform 2 at Ashford station and switch to battery power.
  • Run to Hastings on battery power.
  • Run to Aahford on battery power.
  • Stop in Platform 2 at Ashford station and switch to 25 KVAC overhead power.
  • Run from Ashford to St. Pancras along HS1 using the 25 KVAC overhead power

The battery would be charged on HS1 and using the third-rail electrification at Hastings.

How Big Would The Battery Need To Be?

The test IPEMU had a battery capacity of 500 kWh and based on what is said in the Technical Appendix was capable of perhaps 150 miles on battery power.

This works out as a consumption of under one kWh per car per mile.

So a six-car train would need perhaps 200 kWh to do a single trip on the 26¼ mile Marshlink Line. Providing of course it was fully charged before starting the journey.

Could Hitachi Modify a Class 395 Train To Have A Battery Option?

Hitachi have been developing battery trains for several years.

I believe that if Bombardier can create and test a battery-electric version of a Class 379 train, in under a year, then Hitachi could do the same with any of their A train family, which includes Class 800/801/802/395 trains.

This page on the Hitachi web site is entitled AT300 – INTERCITY HIGH SPEED.

The page has a picture of a Class 395 train and it has this caption.

The Class 395 is the first High Speed commuter train in the UK and part of Hitachi’s family of AT300 units. Its introduction to HS1 in 2009 continues to be a success story and it has set new standards for performance in High Speed trains in the UK.

Underneath the picture, it gives a Technical Outline for the trains, where this is said.

Power Supply: (25kVAC / 750 Vdc / Battery)

This may only be for train hotel power, but certainly the trains can use batteries.

Conclusion On The Type Of Train

I have no reason to believe that St. Pancras to Hastings copuldn’t be run by either type of train.

Although there is the problem of whether trains carrying diesel can go throyugh the HS1 tunnels.

The new operator for the Southeastern Franchise will chose the deal they liked.

Destination Stations

The Technical Appendix to the Kent Area Route Study proposes three possible destination stations.

Hastings

Hastings station has some advantages.

  • It may be easier for operational reasons.
  • Using Platform 1 would allow cross-platform interchange with trains going West.
  • Only minimal signalling and track changes are needed.
  • A 25-30 minute dwell time at the station is good for recovery after a late arrival.

The big disadvantage is that Bexhill will not be served.

Bexhill

Stakeholders would like the service to go to Bexhill station.

Train operation doesn’t appear to be as simple as at Hastings.

Eastbourne

Eastbourne station also offers advantages.

  • There could be a 20-25 minute dwell time at Eastbourne, which would help in service recovery.
  • Sic-car trains would offer signification extra capacity between Hastings and Eastbourne, where it is needed.
  • The line between Bexhill and Eastbourne was resignalled in 2015.
  • Eastbourne to St. Pancras would be a good alternative route in times of perturbation.
  • With extra work at Hampden Park station, it could provide a faster route to Brighton and Gatwick Airport.

The only disadvantage is that an extra train would be needed to run the service.

Conclusion On The Destination

All three stations could be a suitable destination.

I feel that if the choice of trains favours battery-electric, that Eastbourne might have a useful advantage in recharging the batteries.

Track Improvements

The Technical Appendix to the Kent Area Route Study proposes various track improvements in various places from Ashford to Brighton.

It looks like Network Rail are preparing the infrastructure for faster services all along the South Coast.

Conclusion

Amber Rudd has put her name to a well-worked article.
