Alstom Hydrogen Aventras And Teesside
In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I give my thoughts on Alstom’s new hydrogen train, which I have called the Alstom Hydrogen Aventra.
Would this train be suitable for the local railways around Teesside?
Fuelling The Change On Teesside Rails is a post based on an interview with Tees Valley Mayor; Ben Houchen in Rail Magazine.
Teesside is getting ready for hydrogen.
- They have identified a site for a specialist depot for hydrogen-powered trains.
- There is plenty of hydrogen available from chemical works in the area.
All they need is some trains and I think the Alston Hydrogen Aventras would fill the need admirably.
I also believe that with its history of heavy industry, steel and chemicals, the residents of Teesside and the Tees Valley would take to hydrogen trains.
I wrote Fuelling The Change On Teesside Rails in January 2020 and since then the Department of Transport has funded a study to examine the extension of the Tees Valley Line past Bishop Auckland, which I wrote about in Reopening The Darlington – Weardale Line To Passenger Services.
On the subject of rolling stock for the Weardale Line, I said this in the Weardale Line post.
There is no point in extending the line in these days of global warming without providing zero-carbon trains.
The Tees Valley Combined Authority is keen on hydrogen and there are good reasons.
-
- There is hydrogen available from chemical plants on Teesside.
- Hydrogen will give the trains a long range.
- The trains would probably only need refuelling once a day.
- In addition, Alstom are looking for an order for their Class 600 train, which is a conversion of a Class 321 train.
But I have my doubts about Alstom’s trains and Hitachi have doubts about hydrogen.
Consider.
-
- Do you really want to run hydrogen trains on a line where steam trains run?
- Darlington station is fully-electrified and it is also to be remodelled for more capacity and High Speed Two.
- Bishop Auckland and Darlington is just twelve miles.
- Darlington and Saltburn is just thirty miles.
With charging systems at Bishop Auckland, Saltburn and Stanhope, I am fairly sure Hitachi could develop an electric train for Teesside’s railways.
When I wrote the Weardale Line post, I was veering towards the Hitachi battery-electric trains, but the launch of the Alstom Hydrogen Aventra may have changed that.
Conclusion
The new trains for Teesside could become a fight between Hitachi with their battery-electric trains and Alstom with their Hydrogen Aventras.
If there is a fight of the technologies, who wins on Teesside could be important in deciding the future of world-wide rail transport.
Is it slightly ironic, that this battle could be happening close to the birthplace of railways?
Hitachi Rail And Angel Trains To Create Intercity Battery Hybrid Train On TransPennine Express
The title of this post, is the same as that of this Press Release from Hitachi Rail.
The press release starts with these three points.
- Hitachi Rail, Angel Trains and TransPeninne Express (TPE) agree to trial retrofitting battery on intercity train
- Trial, starting next year, can cut fuel usage by at least 20% and reduce emissions on Transpennine network from 2022 onwards
- Tri-mode service can cut noise pollution in urban areas and improve air quality.
Hitachi also point to this infographic.
This very much looks to be a step forward from the Intercity Tri-Mode Battery Train that was announced in December 2020 in this press release from Hitachi which is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%.
The Intercity Tri-Mode Battery Train is described in this Hitachi infographic.
The specifications are very similar, except for the following.
- The battery range is given as five kilometres.
- Fuel savings are up to 30% instead of at least 20%.
- A performance increase of 30 % is claimed.
- The upgrade appears to be able to be fitted to Hitachi intercity trains, as opposed to a straight replacement of one engine by batteries.
It looks to me, that Hitachi have been working hard to improve their design.
I think this paragraph of the press release is key.
The trial will see a diesel engine replaced by batteries to help power a five-carriage train, along with the two remaining engines. The power provided by the batteries will help to reduce the amount of fuel required to operate the train.
Hitachi don’t say, but I suspect the trains and their batteries have a lot of energy saving features.
- Regenerative braking is already used to power some services like lighting and air-conditioning on the trains.
- But I suspect regenerative braking will also be used to recharge the batteries.
- A sophisticated computer system will drive the train in the most optimal manner.
- Hopefully, diesel will only be used as a last resort.
Features like these and others will enable the trains to jump gaps in the electrification. As more and more tricks are added and batteries hold more charge, the gaps the trains will be able to cross will get larger.
Five kilometres might not sound much, but I think it could be surprisingly useful.
I will use an example from the Midland Main Line to illustrate how the trains and discontinuous electrification might work.
In Discontinuous Electrification Through Leicester Station, I described the problems at Leicester station and how discontinuous electrification could solve the problem.
The following is a modified extract from that post.
This Google Map shows the bridge and the Southern end of the station.
It looks to me, that Leicester station and the road, would have to be closed to traffic for some time, if the bridge were to be rebuilt, to allow the erection of electrification through the area. Leicester and all train passengers would love that!
A solution could be discontinuous electrification.
- The electrification from the South, would finish on the South side of bridge.
- The electrification from the North, would finish at a convenient point in Leicester station or just to the North.
- Electric trains would cover the gap of up to five kilometres on battery power.
Note.
Pantographs could be raised and lowered, where the wires exist.
Trains would probably use a stopping profile in Leicester station, that ensured they stopped with full batteries.
This would mean they had enough electricity to get back up to speed and reconnect to the electrification on the other side of the station.
To get an idea at how long five kilometres is in the Centre of Leicester, this Google Map shows the Leicester station.
Note that the platforms are around three hundred metres long.
In other words the electrification can be kept well away from the station and its troublesome bridge.
How much money would be saved and disruption avoided?
Application To The TransPennine Express Routes
These are the various routes, where Class 802 trains could be used.
Liverpool Lime Street And Edinburgh, Newcastle, Scarborough Or York
Sections are as follows.
- Liverpool Lime Street and Manchester Victoria – 31.7 miles – Electrified
- Manchester Victoria and Stalybridge – 8 miles – Electrified probably by 2024
- Stalybridge and Huddersfield – 18 miles – Diesel
- Huddersfield and Dewsbury – 8 miles – Electrified probably by 2024
- Dewsbury and Leeds – 9.2 miles – Diesel
- Leeds and York – 25.6 miles – Electrified probably by 2024
- York and Newcastle – 80.2 miles – Electrified
Note.
- All services take a common route between Liverpool Lime Street and York.
- A surprising amount is electrified.
- A further 42 miles are being electrified.
- The 3 km Morley Tunnel between Dewsbury and Leeds might not be electrified.
- The 5 km Standedge Tunnel between Huddersfield and Stalybridge might not be electrified.
It looks to me that the 5 km battery range will avoid electrification of two long Victorian tunnels.
Manchester Airport And Newcastle Or Redcar Central
Sections are as follows.
- Manchester Airport and Manchester Victoria – 13.2 miles – Electrified
- Manchester Victoria and Stalybridge – 8 miles – Electrified probably by 2024
- Stalybridge and Huddersfield – 18 miles – Diesel
- Huddersfield and Dewsbury – 8 miles – Electrified probably by 2024
- Dewsbury and Leeds – 9.2 miles – Diesel
- Leeds and York – 25.6 miles – Electrified probably by 2024
- York and Newcastle – 80.2 miles – Electrified
- Northallerton and Redcar Central – 29 miles – Diesel
The route goes through the Morley and Standedge tunnels.
Manchester Piccadilly And Hull
Sections are as follows.
- Manchester Piccadilly and Stalybridge – 7.5 miles – Electrified probably by 2024
- Stalybridge and Huddersfield – 18 miles – Diesel
- Huddersfield and Dewsbury – 8 miles – Electrified probably by 2024
- Dewsbury and Leeds – 9.2 miles – Diesel
- Leeds and Selby – 21 miles – Diesel
- Selby and Hull – 31miles – Diesel
The route goes through the Morley and Standedge tunnels.
Manchester Piccadilly And Huddersfield
The route goes through the Standedge tunnel.
Huddersfield And Leeds
The route goes through the Morley tunnel.
Manchester Airport And Cleethorpes
The Hope Valley Line which is part of this route has three tunnels.
Perhaps they will use a bit of diesel to get through Totley.
The Future
This paragraph sums up what Hitachi and Angel Trains could see as a possible future direction.
Once complete, the trial provides a pathway for Hitachi Rail, the train builder and maintainer, and Angel Trains, the train’s owner to develop plans to retrofit batteries to the wider fleet.
These plans will probably go in the directions like decarbonisation, more efficient operation and better standards for passengers.
Conclusion
This looks like a solution that has been helped by real ale in an appropriate hostelry.
- The battery range has been chosen so Network Rail don’t necessarily have to electrify the tunnels.
- Full electrification can be used either side of the tunnels.
- Will any stations not be electrified. After all if the trains are using battery power in stations do they need electrification?
- It might be useful to have some more bi-mode freight locomotives, that could traverse the tunnels on diesel or batteries.
Hitachi and Network Rail certainly seem to be cooking up a solution.
Reopening The Darlington – Weardale Line To Passenger Services
On October 27th this Beeching Reversal Project was given £50,000 to build a case for reopening.
The current Weardale Railway is a heritage line, that extends the current National Rail service between Darlington and Bishop Auckland stations further up Weardale.
- It is a single track railway.
- The current operational length is 18 miles between Bishop Auckland West and Stanhope stations.
- The line could be extended a few miles to the site of the former Wearhead station.
- Thre is a station at the village of Stanhope which i has a castle, a community hospital and a population of 1,600.
- There is a station at the village of Frosterley which has a population of 700.
- There is a station at the village of Witton-le-Wear which has a population of 700.
- There seem to be lots of caravan parks along the river.
- From my virtual helicopter, the track looks in reasonable condition.
- There appear to be a couple of passing loops.
- There don’t appear to be any tunnels.
- The Weardale Railway has several bridges over the River Wear.
- I suspect the scenery is not bad.
To my untrained eye, this section of railway would appear to have possibilities for reopening, without any serious engineering problems.
These are a few of my thoughts.
The Connection To National Rail
This Google Map shows Bishop Auckland station, where the Weardale Railway connects to the National Rail network.
Note.
- The station appears to be well-placed in the town.
- There is plenty of space for tracks connecting the two systems.
I suspect that building a combined through and terminal station that would satisfy the needs of all stakeholders would not be the most challenging of tasks.
Could The Extended Line Have A Japanese Fairy Godmother?
Consider.
- Hitachi’s train factory at Newton Aycliffe is five miles to the South of Bishop Auckland.
- Hitachi have stated that they are developing battery-electric trains for lines without electrification.
- Developers of modern trains with complicated computer systems seem to go through many software versions.
I have to ask the question, if Hitachi would like to have a twenty-mile test track on their doorstep?
If they were testing trains that were agnostic about their power supply, the Weardale Railway would not need to be electrified, although there could be a couple of charging systems.
Would Access To The Quarries At Wearhead Be Needed?
The original Weardale Railway was built to access the quarries at Wearhead, but they switched to road transport some years ago.
This Google Map shows the Wearhead area.
Note.
- Wearhead is in the North-West corner of the map.
- There is a quarry and there used to be a fluorspar mine.
- The white scar at the East of the map was a cement works.
Is there something, that could possibly be mined in this area, that could be taken out by train.
I think it should be born in mind, that mining and quarrying used to be a very dirty and carbon-intensive industry, but big mining companies are now embracing zero-carbon technology.
Could A Holiday Company Like Center Parcs Develop A Site In The Wear Valley?
I noticed a lot of caravans and chalets, as I examined the line.
Could a big operator like Center Parcs develop one of their holiday centres?
It could even be developed with a station.
Is New Housing Needed?
Does the local authority want to develop housing along the line?
What Rolling Stock Will Be Used?
There is no point in extending the line in these days of global warming without providing zero-carbon trains.
The Tees Valley Combined Authority is keen on hydrogen and there are good reasons.
- There is hydrogen available from chemical plants on Teesside.
- Hydrogen will give the trains a long range.
- The trains would probably only need refuelling once a day.
- In addition, Alstom are looking for an order for their Class 600 train, which is a conversion of a Class 321 train.
But I have my doubts about Alstom’s trains and Hitachi have doubts about hydrogen.
Consider.
- Do you really want to run hydrogen trains on a line where steam trains run?
- Darlington station is fully-electrified and it is also to be remodelled for more capacity and High Speed Two.
- Bishop Auckland and Darlington is just twelve miles.
- Darlington and Saltburn is just thirty miles.
With charging systems at Bishop Auckland, Saltburn and Stanhope, I am fairly sure Hitachi could develop an electric train for Teesside’s railways.
Conclusion
Hitachi could be key to the design of the reopening of the Darlington and Weardale Line.
The Northern Ends Of The Platforms At Kings Cross Station
These pictures show the Northern ends of the platforms at Kings Cross station.
The two trains are both nine-car Hitachi Class 800 or Class 801 trains and I was standing in line with their noses.
I wonder what is the maximum length of trains that can be handled in these platforms.
- They can certainly handle ten-car trains, as LNER run these to Leeds.
- Hitachi have designed the trains, so they can be up to twelve-cars, which are 312 metre long trains.
- Looking at maps, I suspect that eleven-car trains would be the largest that can be handled.
But surely to maximum the number of passengers handled in the station, the platforms should be able to handle the longest Hitachi trains.
- Unless, the capacity of an individual train is limited by the gate-lines and Network Rail have said that ten-car trains are the longest allowed.
- Or would twelve-car trains be two far to walk with lots of luggage.
But ten-car trains would allow Lumo to double-up trains to increase capacity selectively, when perhaps, there is an important sporting event.
So when say the Culcutta Cup is taking place, an early morning train to the match and a late evening return could be doubled to add another four hundred seats.
But the current Lumo timetable only shows just two trains on a Saturday.
- London King’s Cross – Edinburgh, which leaves at 10:25 and arrives at 14:57.
- Edinburgh – London King’s Cross, which leaves at 08:49 and arrives at 13:17.
Not very good to go to the rugby or a birthday lunch with your mum.
But realtimetrains reveals two early morning paths allocated to Lumo.
- London King’s Cross – Edinburgh, which leaves at 05:45 and arrives at 10:06.
- Edinburgh – London King’s Cross, which leaves at 05:36 and arrives at 10:04.
So you can get to the other capital, but is there a later last train back?
Oh! Yes there is! And again they are revealed by realtimetrains.
- London King’s Cross – Edinburgh, which leaves at 18:27 and arrives at 22:56.
- Edinburgh – London King’s Cross, which leaves at 17:56 and arrives at 22:29.
Is the Southbound service earlier, as Murrayfield is closer to Waverly station, than Twickenham is to King’s Cross?
If the return was fifty pounds and the trains were doubles, that could be revenue of around £ 40,000. There would be more electricity and track access charges, and they’d need extra train crew, but Lumo would surely be quids in!
Lumo’s financial model has several nice little earners.
LNER’s Middlesbrough And London Service Starts On December 13th
Tucked at the bottom of the article entitled LNER Tickets For Christmas Getaway in Edition 939 of Rail Magazine, there is this paragraph separated from the article by a sole bullet point.
LNER has confirmed that from December 13 it will run a new weekday service between London King’s Cross and Middlesbrough.
It has already made an appearance on Real Time Trains and I can find the following details.
- There will be one train per day (tpd)
- Intermediate stops will be at Thornaby and York.
- The Middlesbrough and London service will leave Middlesbrough from Platform 1 at 07:08 and arrive in King’s Cross at 10:22.
- The London and Middlesbrough service will leave King’s Cross at 15:25 and arrive in Middlesbrough in Platform 2 at 18:18.
These are my thoughts.
Trains Per Day
One train per day, is obviously an introductory service and like services to Harrogate and Lincoln, the number of services will ramp up to perhaps four or five tpd, if the demand is there and the paths and trains are available.
Journey Times
Consider
- The Southbound journey takes three hours and fourteen minutes with a time of two hours and nine minutes between York and King’s Cross
- The Northbound journey takes two hours and fifty-three minutes with a time of one hour and fifty-six minutes between King’s Cross and York.
- Some services between King’s Cross and York are as fast as one hour and forty-eight minutes.
- Middlesbrough and York seems to take around 52-58 minutes.
- These Middlesbrough and York timings are consistent with TransPennine Express.
- Digital signalling could offer savings in journey time between York and London.
I think it is very likely as the timetable improves, that timings between Middlesbrough and London could be around two hours and forty minutes.
Electrification
The route is fully electrified except for between Middlesbrough and Longlands Junction, where it joins the electrification of the East Coast Main Line, which is a distance of twenty-two miles.
Hitachi are developing a battery-train, which they call the Hitachi Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
Note.
- LNER’s current Class 800 trains will probably be able to be converted to this train.
- A range on battery power of upwards of forty miles would be expected.
If the range on battery-power can be stretched to perhaps sixty miles, this train should be capable of serving Middlesbrough without the need for any extra charging at the terminus.
I am sure Hitachi would like to see their battery-electric trains running between King’s Cross and Middlesbrough, as it would be an ideal route on which to show the trains to prospective customers, given that their factory is at Newton Aycliffe.
Conclusion
This could be good demonstration battery-electric service for Hitachi and LNER.
ORR’s Policy On Third Rail DC Electrification Systems
The title of this post is the same as that of a document I downloaded from this page on the Office of Rail and Road web site.
It is one of the most boring legal documents, that I have ever read and I have read a few in my time.
As I read it, effectively it says that new third-rail electrification is banned because of Health and Safety issues, which take precedence.
But only once in the document is new technology mentioned, that might make third-rail safer and that is a reference to the Docklands Light Railway, where the third rail is shielded.
I am an Electrical Engineer and I was designing safety systems for heavy industrial guillotines at fifteen as a vacation job in a non-ferrous metals factory.
One design of an ideal electric railway would have battery-electric trains, that were charged in stations by third-rail. The third-rail would only be energised, when a train was over the top and needed to be charged. In effect the train would act as an all-enclosing guard to the conductor rail.
Electrification Of The West Of England Main Line
The West of England Main Line runs between Basingstoke and Exeter via Salisbury. It is one of the longest, if not the longest main lines in England, that is not electrified.
It would probably need to be electrified with 750 VDC third-rail electrification, as that standard is used between London Waterloo and Basingstoke.
In Solving The Electrification Conundrum, I described a system being developed by Hitachi, that would use battery-electric trains that were charged by short sections of electrified line every fifty miles or so. For reasons of ease of installation and overall costs, these short sections of electrification could be third-rail, that was electrically dead unless a train was connected and needed charging. These electrified sections could also be in stations, where entry on to the railway is a bit more restricted.
Conclusion
The Office of Rail and Road needs to employ a few more engineers with good technical brains, rather than ultra-conservative risk-averse lawyers.
As a sad footnote, I live in East London, where trespassers are regularly electrocuted on the railway. But usually, it is when idiots are travelling on top of container trains and inadvertently come into contact with the overhead electrification.
Hitachi Class 800 Train Or Pendelino?
I have had several day trips on hot days on Hitachi Class 800 trains or similar since the pandemic started to places like Bristol, Cardiff, Doncaster, Grantham, Hull and Westbury.
I’ve done a couple of trips in Pendelinos or Class 390 trains to Birmingham and Liverpool.
In addition, I’ve taken a couple of trips on other trains to Corby, Ipswich, Sheffield and Southampton.
It must have been sometime in 2018, when I took one of the first Pendelinos to Blackpool after that station was first electrified.
It was a journey on which I first noticed being unwell on a Pendelino. I travelled in First and remember complaining to the steward and said that some taff didn’t like the trains after their recent air-conditioning upgrade.
Perhaps, Virgin Trains chose a system that would be cheaper to run and it is not on a par with the quality systems used by Bombardier and Hitachi?
I have been testing the atmosphere in trains like a Class 345, 378 or 800 and the temperature is usually 25-26 °C and a humidity around 40-60 %. I haven’t tested a Pendolino yet!
I must say, I’ve never ended up in hospital after a trip out of London, except after a recent trip on a Pendelino to Birmingham, that I wrote about in A Mysterious Attack On My Body.
In that post, I also said this about the Pendelinos.
I had travelled between Euston and Wolverhampton on my least favourite trains – Alstom’s Class 390 trains.
-
- The seats don’t align well with the windows.
- The trains are cramped because of all the tilting mechanism.
These trains must a nightmare for anybody taller than my 1.70 metres or heavier than my sixty-two kilos.
But the biggest problem of these Pendolino trains is that Alstom updated the air-conditioning a few years ago for Virgin a few years ago and I find the air inside too dry.
So in future, I won’t be travelling on a Pendelino, unless I travel in First!
I also can’t wait until Avanti West Coast get new Hitachi Class 807 trains on the Euston and Liverpool route!
Vivarail At COP26
This press release from Network Rail is entitled Network Rail And Porterbrook To Showcase Britain’s Green Trains Of The Future At COP26.
These two paragraphs are from the end of the first section of the press release.
It is envisaged that the HydroFLEX may also be used to transport visitors to see the Zero Emission Train, Scotland’s first hydrogen powered train.
Network Rail is also in the earlier stages of planning a similar event with Vivarail to bring an operational battery train to COP26.
Vivarail have taken battery trains to Scotland before for demonstration, as I wrote about in Battery Class 230 Train Demonstration At Bo’ness And Kinneil Railway.
Will other train companies be joining the party?
Alstom
It looks like Alstom’s hydrogen-powered Class 600 train will not be ready for COP26.
But I suspect that the French would not like to be upstaged by a rolling stock leasing company and a university on the one hand and a company with scrapyard-ready redundant London Underground trains on the other.
I think, they could still turn up with something different.
They could drag one of their Coradia iLint trains through the Channel Tunnel and even run it to Scotland under hydrogen power, to demonstrate the range of a hydrogen-powered train.
Alstom have recently acquired Bombardier’s train interests in the UK and there have been rumours of a fleet of battery-electric Electrostars, even since the demonstrator ran successfully in 2015. Will the prototype turn up at COP26?
Alstom’s UK train factory is in Widnes and I’ve worked with Liverpudlians and Merseysiders on urgent projects and I wouldn’t rule out the Class 600 train making an appearance.
CAF
Spanish train company; CAF, have impressed me with the speed, they have setup their factory in Newport and have delivered a total of well over a hundred Class 195 and Class 331 trains to Northern.
I wrote Northern’s Battery Plans, in February 2020, which talked about adding a fourth-car to three-car Class 331 trains, to create a battery-electric Class 331 train.
Will the Spanish bring their first battery-electric Class 331 train to Glasgow?
I think, they just might!
After all, is there a better place for a train manufacturer looking to sell zero-carbon trains around the world to announce, their latest product?
Hitachi
A lot of what I have said for Alstom and CAF, could be said for Hitachi.
Hitachi have announced plans for two battery-electric trains; a Regional Battery Train and an Intercity Tri-Mode Battery Train.
I doubt that either of these trains could be ready for COP26.
But last week, I saw the new Hitachi Class 803 train speeding through Oakleigh Park station.
This is not a battery-electric train, where battery power can be used for traction, but according to Wikipedia and other sources, it is certainly an electric train fitted with batteries to provide hotel power for the train, when the overhead electrification fails.
Are these Class 803 trains already fitted with their batteries? And if they are, have they been tested?
And who is building the batteries for the Class 803 trains?
The traction batteries for Hitachi’s two battery-electric trains are to be produced by Hyperdrive Innovation of Sunderland, which is not far from Hitachi’s train factory at Newton Aycliffe.
As an engineer, I would suspect that a well-respected company like Hyperdrive Innovation, can design a battery-pack that plugs in to Hitachi’s trains, as a diesel engine would. I would also suspect that a good design, would allow an appropriate size of battery for the application and route.
I feel it is very likely, that all batteries for Hitachi’s UK trains will be designed and build by Hyperdrive Innovation.
If that is the case and the Class 803 trains are fitted with batteries, then Hitachi can be testing the battery systems.
This document on the Hitachi Rail web site, which is entitled Development of Class 800/801 High-speed Rolling Stock for UK Intercity Express Programme, gives a very comprehensive description of the electrical and computer systems of the Hitachi trains.
As an engineer and a computer programmer, I believe that if Hyperdrive Innovation get their battery design right and after a full test program, that Hitachi could be able to run battery-electric trains based on the various Class 80x trains.
It could be a more difficult task to fit batteries to Scotland’s Class 385 trains, as they are not fitted with diesel engines in any application. Although, the fitting of diesel engines may be possible in the global specification for the train.
It is likely that these trains could form the basis of the Regional Battery Train, which is described in this infographic.
Note.
- The Class 385 and Regional Battery trains are both 100 mph trains.
- Class 385 and Class 80x trains are all members of Hitachi’s A-Train family.
- Regional Battery trains could handle a lot of unelectrified routes in Scotland.
I wouldn’t be surprised to see Hitachi bring a battery-equipped train to COP26, if the Class 803 trains have a successful introduction into service.
Siemens
Siemens have no orders to build new trains for the national rail network in the UK.
But there are plans by Porterbrook and possibly other rolling stock leasing companies and train operators to convert some redundant Siemens-built trains, like Class 350 trains, into battery-electric trains.
According to Wikipedia, Siemens upgraded East Midlands Railways, Class 360 trains to 110 mph operation, at their Kings Heath Depot in Northampton.
Could Siemens be updating one of the Class 350 trains, that are serviced at that depot, to a prototype battery-electric Class 350 train?
Stadler
Stadler have a proven design for diesel-electric, battery-electric and hydrogen trains, that they sell all over the world.
In the UK, the only ones in service are Greater Anglia’s Class 755 trains, which are diesel-electric bi-mode trains.
The picture shows one of these trains at Ipswich.
- They are 100 mph trains.
- Diesel, battery or hydrogen modules can be inserted in the short PowerPack car in the middle of the train.
- Diesel-battery-electric versions of these trains have been sold for operation in Wales.
- The interiors of these trains are designed for both short journeys and a two-hour run.
There is a possibility, that these trains will be upgraded with batteries. See Battery Power Lined Up For ‘755s’.
Conclusion
Times will be interesting in Glasgow at COP26!
Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train
This Hitachi infographic describes a Hitachi Intercity Tri-Mode Battery Train.
Hitachi are creating the first of these battery trains, by replacing one of the diesel power-packs in a Class 802 train with a battery-pack from Hyperdrive Innovation of Sunderland.
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%, gives a few more details.
The Class 802 train has the following characteristics.
- Five cars.
- Three diesel power-packs, each with a power output of 700 kW.
- 125 mph top speed on electricity.
- I believe all intermediate cars are wired for diesel power-packs, so can all intermediate cars have a battery?
In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I estimated that the trains need the following amounts of energy to keep them at a constant speed.
- Class 801 train – 125 mph 3.42 kWh per vehicle mile
- Class 801 train – 100 mph 2.19 kWh per vehicle mile
The figures are my best estimates.
The Wikipedia entry for the Class 800 train, also gives the weight of the diesel power-pack and all its related gubbins.
The axle load of the train is given as 15 tonnes, but for a car without a diesel engine it is given as 13 tonnes.
As there are four axles to a car, I can deduce that the diesel power-pack and the gubbins, weigh around eight tonnes.
How much power would a one tonne battery hold?
This page on the Clean Energy institute at the University of Washington is entitled Lithium-Ion Battery.
This is a sentence from the page.
Compared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. They have one of the highest energy densities of any battery technology today (100-265 Wh/kg or 250-670 Wh/L).
Using these figures, a one-tonne battery would be between 100 and 265 kWh in capacity, depending on the energy density.
As it is likely that if the diesel power-pack replacement would probably leave things like fuel tanks and radiators behind, so that the diesel engines could be reinstalled, I would expect that a battery of around four tonnes would be fitted.
On the basis of the University of Washington’s figures a 400 kWh battery pack would certainly be feasible.
Using. the energy use at 100 mph of 2.19 kWh per vehicle mile, I can get the following ranges for different battery sizes.
- 400 kWh battery – 36.53 miles
- 500 kWh battery – 45.67 miles
- 600 kWh battery – 54.80 miles
- 800 kWh battery – 73.06 miles
As Lincoln and Newark are just 16.6 miles apart, it looks to me that a 500 or 600 kWh battery could be a good choice for that route, as it would leave enough hotel power for the turnround.
It should also handle shorter routes like these.
- Newbury and Bedwyn – 13.3 miles.
- Didcot and Oxford – 10.3 miles
- Newark and Lincoln – 16.6 miles
- Leeds and Harrogate – 18.3 miles
- Northallerton and Middlesbrough – 20 miles
- Hull and Temple Hirst Junction and Hull – 36.1 miles
Some routes like Temple Hirst Junction and Hull would need charging at the destination.
The Range Of A Five Car Train With Three Batteries
Suppose a Hitachi Intercity Tri-Mode Battery Train had three battery-packs and no diesel engines.
- It would be based on Hitachi Intercity Tri-Mode Battery Train technology.
- It would have two driver cars without batteries.
- It would have three intermediate cars with 600 kWh batteries.
- It would have 1800 kWh in the batteries.
- The train would be optimised for 100 mph running.
- My estimate says it would need 2.19 kWh per vehicle mile to cruise at 100 mph.
It could have a range of up to 164 miles.
If the batteries were only 500 kWh, the range would be 137 miles.
The Ultimate Battery Train
I think it would be possible to put together a nine car battery-electric train with a long range.
- It would be based based on Hitachi Intercity Tri-Mode Battery Train technology, which would be applied to a Class 800 or Class 802 train.
- It would have two driver cars without batteries.
- It would have seven intermediate cars with 600 kWh batteries.
- It would have a total battery capacity of 4200 kWh.
- The train would be optimised for 100 mph running.
- My estimate in How Much Power Is Needed To Run A Train At 125 Or 100 mph?, said it would need 2.19 kWh per vehicle mile to cruise at 100 mph.
That would give a range of over 200 miles.
If the batteries were only 500 kWh, the range would be 178 miles.
Aberdeen, Inverness, Penzance and Swansea here we come.
Can Hitachi Increase The Range Further?
There are various ways that the range can be improved.
- More electrically-efficient on-board systems like air-conditioning.
- A more aerodynamic nose.
- Regenerative braking to the batteries.
- Batteries with a higher energy density.
- Better driver assistance software.
Note.
- Hitachi have already announced that the Class 810 trains for East Midlands Railway will have a new nose profile.
- Batteries are improving all the time.
I wouldn’t be surprised to see a ten percent improvement in range by 2030.
Conclusion
I was surprised at some of the results of my estimates.
But I do feel that Hitachi trains with 500-600 kWh batteries could bring a revolution to train travel in the UK.
Edinburgh And Aberdeen
Consider.
- The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
- There could be an intermediate charging station at Dundee.
- Charging would be needed at Aberdeen.
I think Hitachi could design a train for this route.
Edinburgh And Inverness
Consider.
- The gap in the electrification is 146 miles between Stirling and Inverness.
- This could be shortened by 33 miles, if there were electrification between Stirling and Perth.
- Charging would be needed at Inverness.
I think Hitachi could design a train for this route.
£100m Station Revamp Could Double Local Train Services
The title of this post, is the same as that of this article on the Northern Echo.
This is the opening paragraph.
Officials behind plans for a £100m-plus transformation of Darlington’s Bank Top Station have confirmed it will remain the only one on the East Coast Mainline without a platform specifically for the London to Scotland service.
Darlington station has made various appearances in my life, all of which have been pleasurable ones.
I went several times to ICI’s Wilton site on Teesside in the 1970s, when the route to London was worked by the iconic Class 55 locomotives or Deltics.
I wrote about one memorable trip home from Darlington in The Thunder of Three-Thousand Three-Hundred Horses.
Over the years, I also seem to have had several clients for my computing skills in the area, including the use of my data analysis software; Daisy at Cummins Engines in the town.
And lately, it’s been for football at Middlesbrough to see Ipswich play, where I’ve changed trains. Sometimes, Town even won.
The improvements planned for the station are two-fold.
Improvement Of Local Services
This paragraph from Wikipedia, sums up the local train services on the Tees Valley Line between Saltburn and Bishop Auckland via Darlington, Middlesbrough and Redcar.
Northern run their Tees Valley line trains twice hourly to Middlesbrough, Redcar and Saltburn (hourly on Sundays), whilst the Bishop Auckland branch has a service every hour (including Sundays). The company also operates two Sundays-only direct trains to/from Stockton and Hartlepool.
If ever a route needed improvement it is this one.
This paragraph from the Northern Echo article, outlines the plans for Darlington station.
The meeting was also told the overhaul, which will see new platforms, a new station building, parking and an interchange for passengers, alongside other improvements, would also double capacity on Tees Valley and Bishop Auckland lines, meaning four trains an hour on the former and two trains an hour on the latter.
I also believe that the route is a shoe-in for zero-carbon services; hydrogen or battery electric.
Hydrogen Trains On Teesside
In Fuelling The Change On Teesside Rails, I discuss using hydrogen powered trains for the lines in the area and they could certainly provide services on more than just the Tees Valley Line.
- Teesside certainly has big plans for hydrogen to fuel its chemical industry.
- Hydrogen powered transport in the area has been backed by the Government, as I wrote about in Tees Valley Wins £1.3million Project To Bring Hydrogen Vehicles To The Region.
- Plans are advancing for a depot for hydrogen-powered trains at Lackenby.
The hydrogen powered trains would probably be this Alstom Breeze.
They would appear to be in pole position to change the image of Teesside’s trains.
Battery Electric Trains On Teesside
But I suspect. that an Anglo-Japanese partnership, based in the North-East could have other ideas.
- Hitachi have a train factory at Newton Aycliffe on the Tees Valley Line.
- Hyperdrive Innovation design and produce battery packs for transport and mobile applications in Sunderland.
The two companies have launched the Regional Battery Train, which is described in this Hitachi infographic.
Note than 90 kilometres is 56 miles, so the train has a very useful range.
Hitachi have talked about fitting batteries to their express trains to serve places like Middlesbrough, Redcar and Sunderland with zero-carbon electric services.
But their technology can also be fitted to their Class 385 trains and I’m sure that Scotland will order some battery-equipped Class 385 trains to expand their vigorous electric train network.
Both Scotland and Teesside will need to charge their battery trains.
Example distances on Teesside include.
- Darlington and Saltburn – 28 miles
- Darlington and Whitby – 47 miles
- Darlington and Bishop Auckland – 12 miles
The last route would be possible on a full battery, but the first two would need a quick battery top-up before return.
So there will need to be strategically-placed battery chargers around the North-East of England. These could include.
- Hexham
- Nunthorpe
- Redcar or Saltburn – This would also be used by TransPennine Express’s Class 802 trains, if they were to be fitted with batteries.
- Whitby
If Grand Central did the right thing and ran battery electric between London and Sunderland, there would probably be a need for a battery charger at Sunderland.
It appears that Adrian Shooter of Vivarail has just announced a One-Size-Fits-All Fast Charge system, that has been given interim approval by Network Rail.
I discuss this charger in Vivarail’s Plans For Zero-Emission Trains, which is based on a video on the Modern Railways web site.
There is more about Vivarail’s plans in the November 2020 Print Edition of the magazine, where this is said on page 69.
‘Network Rail has granted interim approval for the fast charge system and wants it to be the UK’s standard battery charging system’ says Mr. Shooter. ‘We believe it could have worldwide implications.’
I believe that Hitachi and Hyperdrive Innovation, with a little bit of help from friends in Seaham, can build a battery-electric train network in the North-East.
The Choice Between Hydrogen And Battery Electric
Consider.
- The hydrogen trains would need a refuelling system.
- The battery electric trains would need a charging structure, which could also be used by other battery electric services to and from the North-East.
- No new electrification or other infrastructure would be needed.
- If a depot is needed for the battery electric trains, they could probably use the site at Lackenby, that has been identified as a base for the hydrogen trains.
Which train would I choose?
I think the decision will come down to politics, money and to a certain extent design, capacity and fuel.
- The Japanese have just signed a post-Brexit trade deal and France or rather the EU hasn’t.
- The best leasing deal might count for a lot.
- Vivarail have stated that batteries for a battery electric train, could be leased on a per mile basis.
- The Hitachi train will be a new one and the Alstom train will be a conversion of a thirty year old British Rail train.
- The Hitachi train may well have a higher passenger capacity, as there is no need for the large hydrogen tank.
- Some people will worry about sharing the train with a large hydrogen tank.
- The green credentials of both trains is not a deal-breaker, but will provoke discussion.
I feel that as this is a passenger train, that I’m leaning towards a battery electric train built on the route.
An Avoiding Line Through Darlington
The Northern Echo also says this about track changes at the station.
A meeting of Darlington Borough Council’s communities and local services scrutiny committee was told a bus lane-style route off the mainline at the station would enable operators to run more high-speed services.
Councillors heard that the proposed track changes would enable very fast approaches to Darlington and allow other trains to pass as East Coast Mainline passengers boarded.
Some councillors seem to be unhappy about some trains passing through the station without stopping.
Are their fears justified?
This Google Map shows Darlington station.
Note.
- The station has two long platforms and two South-facing bay platforms.
- There is plenty of space.
- There already appear to be a pair of electrified avoiding lines on the Eastern side of the station.
Wikipedia also says this about how Darlington station will be changed by High Speed Two.
The new high speed rail project in the UK, High Speed 2, is planned to run through Darlington once Phase 2b is complete and will run on the existing East Coast Main Line from York and Newcastle. Darlington Station will have two new platforms built for the HS2 trains on the Main Line, as the station is built just off the ECML to allow for freight services to pass through.
This would appear to suggest that the two current avoiding lines will be turned into high speed platforms.
Current High Speed Services At Darlington
The current high speed services at Darlington are as follows.
- LNER – two trains per hour (tph) – London Kings Cross and Edinburgh
- Cross Country – one tph – Plymouth and Edinburgh or Glasgow
- Cross Country – one tph – Southampton and Newcastle
- TransPennine Express – one tph – Liverpool and Edinburgh
- TransPennine Express – one tph – Manchester Airport and Newcastle
Northbound, this gives eight tph to Newcastle and four tph to Edinburgh
East Coast Trains
East Coast Trains‘s services are not planned to stop at Darlington.
High Speed Two Trains
Darlington is planned to be served by these High Speed Two trains.
- 1 tph – Birmingham Curzon Street and Newcastle via East Midlands Hub, York and Durham
- 1 tph – London Euston and Newcastle via Old Oak Common and York.
Both will be 200 metre High Speed Two Classic-Compatible trains
Northbound, this gives ten tph to Newcastle and four tph to Edinburgh.
As the Eastern Leg of High Speed Two has some spare capacity, I suspect there could be other services through Darlington.
Improvements To The East Coast Main Line
If you look at the East Coast Main Line between Doncaster and Newcastle, the route is a mixture of two and four-track railway.
- Between Doncaster and York, there are two tracks
- Between York and Northallerton, there are four tracks
- Between Northallerton and Darlington, there are two tracks
- North of Darlington, the route is mainly two tracks.
I have flown my virtual helicopter along much of the route and I can say this about it.
- Much of the route is through agricultural land, and where absolutely necessary extra tracks could possibly be added.
- The track is more-or-less straight for large sections of the route.
- Routes through some towns and cities, are tightly hemmed in by houses.
I also believe that the following developments will happen to the whole of the East Coast Main Line before High Speed Two opens.
- Full ERTMS in-cab digital signalling will be used on all trains on the route.
- The trains will be driven automatically, with the driver watching everything. Just like a pilot in an airliner!
- All the Hitachi Class 80x trains used by operators on the route, will be able to operate at up to 140 mph, once this signalling and some other improvements have been completed.
- All level crossings will have been removed.
- High Speed Two is being built using slab track, as I stated in HS2 Slab Track Contract Awarded. I suspect some sections of the East Coast Main Line, that are used by High Speed Two services, will be upgraded with slab track to increase performance and reduce lifetime costs.
Much of the East Coast Main Line could become a 140 mph high speed line, as against High Speed Two, which will be a 225 mph high speed line.
This will mean that all high speed trains will approach Darlington and most other stations on the route, at 140 mph.
Trains will take around a minute to decelerate from or accelerate to 140 mph and if the station stop took a minute, the trains will be up to speed again in just three minutes. In this time, the train would have travelled two-and-a-half miles.
Conclusion
I think that this will happen.
- The Tees Valley Line trains will be greatly improved by this project.
- Trains will generally run at up to 140 mph on the East Coast Main Line, under full digital control, like a slower High Speed Two.
- There will be two high speed platforms to the East of the current station, where most if not all of the High Speed Two, LNER and other fast services will stop.
- There could be up to 15 tph on the high speed lines.
With full step-free access between the high speed and the local platforms in the current station, this will be a great improvement.
