Alstom And Cummins Make A Deal On Hydrogen Rail Technology
I asked Google AI about this deal and receive this reply.
On April 2, 2026, Alstom announced the acquisition of Cummins’ hydrogen fuel cell activities specifically dedicated to the rail sector. This strategic move brings the technology and manufacturing capabilities for Alstom’s Coradia iLint hydrogen trains in-house, following a period where Cummins looked to wind down its wider hydrogen business amid losses in its Accelera energy transition segment.
Here are the key details of the deal:
Scope of the Acquisition
Fuel Cell Technology In-House: Alstom acquired the engineering, product, and support capabilities for the fuel cells used in its existing hydrogen train fleets, specifically the Coradia iLint.
Manufacturing Facilities: The deal includes the transfer of Cummins’ fuel cell manufacturing and assembly site in Herten, Germany, which has been producing for Alstom since 2021.
Targeted Support: The acquisition allows Alstom to strengthen its ability to maintain, improve, and provide support for existing hydrogen fleets in Germany, Italy, and France.
Context and Strategy
Securing Supply Chain: After facing maintenance issues with the fuel cells, which previously required sourcing parts from North America, this move gives Alstom direct control over its key technology.
Strategic Pivot: While Cummins moves to pivot away from the wider hydrogen market following losses in its Accelera unit, Alstom continues to focus on hydrogen as a critical solution for replacing diesel trains on non-electrified, long-haul lines.
Commitment to Hydrogen: Despite a 2025 announcement by Alstom that it would pause “further development” of new hydrogen technology due to funding cuts, this acquisition proves that the company remains committed to supporting and enhancing its current, contracted hydrogen train programs.
Future Impact
Reliability Improvements: Alstom plans to leverage this acquisition to accelerate development work, improve the energy management, durability, and reliability of the Coradia iLint fleet, and ensure the success of projects in Germany, Italy, and France.
Market Position: This acquisition solidifies Alstom’s position as a leader in sustainable rail alternatives, even as battery technology has advanced.
I would agree strongly with the future impact.
My First Ride In An Alstom Coradia iLint
In March 2019 in My First Ride In An Alstom Coradia iLint, I said this.
I’m finally, riding in a hydrogen-powered Alstom Coradia iLint train through the German countryside.
Not as quiet as the two battery trains, I’ve ridden, but that’s because It feels to me that the traction motors are crudely under the passengers and cardan shafts are used to drive the wheels!
Battery electric trains with regenerative braking should be virtually free of any mechanical noise. Both the Class 379 and Class 230 battery demonstrators were almost silent. As electricity generated from hydrogen doesn’t appear to generate much noise, then a hydrogen-powered train can also be almost silent.
From talking to fellow passengers on my German trip, it would appear that the train has been very reliable in service.
Conclusion
Alstom are proving hydrogen would work well in a train designed for that purpose, but updating a DMU with a noisy mechanical transmission, possibly isn’t the best to go.
I now believe that Alstom have everything they need to create a 125 mph tri-mode multiple unit.
Adding in today’s article about hydrogen, I have written enough about Bombardier, which is now Alstom, and their future plans, so that they can build an Alstom 125 mph tri-mode Aventra, with with electric, battery or hydrogen power.
It could be the ultimate train.

The Ultimate Recycled Electric Local Train
This morning, I took a ride across London to ride in the first Class 230 train in public service in London.
I took these pictures of the new block of flats going up at West Ealing station, the charging system for the train and the train.
Note.
- The train is three-cars with a toilet to suit everybody, except possibly Donald Trump, who’d want it in gold.
- The single train is shuttling between West Ealing and Greenford stations.
- Each journey 2.5 mile journey takes eleven minutes.
I was surprised at the number of tables and the quality of the seats.
These are some extra thoughts.
The Blocks Of Flats
Google AI gave me this.
Several new developments around West Ealing station feature tall blocks, with major proposals ranging from 4 to 26 storeys. Key projects include a 26-storey tower, proposed 19–22 storey towers on Manor Road/Waitrose site, and 7–21 storey student accommodation blocks. These, along with other 9-storey developments, are transforming the area into a high-density “transport hub” cluster.
I think the 26-storey West 55 Tower is shown in the first two pictures.
Google AI also says some of the natives are not happy about all the towers.
But I like the “high density” transport hub.
Integrating The Railway And The Housing
Note.
- This would appear to be a good example of integrating the railway and the housing.
- The second picture appears to show a walkway between the station and Tower 55.
- I met a property developer on a train once and he told me, that housing on top of stations without car parking, had better numbers all round, with more flats, less cost and good profit.
- I wonder, if Tower 55, is one of his? He was certainly enthusiastic about the concept.
- Would a Fast-Charge system be easier and very much safer to squeeze in than traditional overhead wiring?
If the flats all don’t have garages, there must be space for other uses.
The Charger At Work
Note.
- The third to the sixth pictures, show the train coming into the station and charging ready for a trip to Greenford.
- The train acts as a heavy safety guard during the process.
- Anything electrical or dangerous is underneath the train.
I would expect that a health and safety expert, would rate the train no more dangerous than a normal train.
There Seems To Have Been A Lot Of Innovative Recycling On The Train
This certainly seems to apply to the seats, which in some cases are the originals remodeled.
A Stylish And Well-Built Train
This phrase would sum up my overall view of the train.
I have a Korean son-in-law and I know a bit, how Koreans think about design.
I would think, that he would like this as it is a stylish and practical train, so it wouldn’t embarrass you or your Korean boss, if you told him to use this train in the UK, to get to your offices.
Using my Korean example, I suspect, that this train could be one that endears itself to its passengers, with its quirky and practical feel, just like the original Mini did.
Adrian Shooter Would Be Pleased
Most Certainly!
I wish all the team well, as I believe this technology and a few trains like 230001 will make their mark on the world.
A Practical Hundred Mile Battery-Electric Route
The Sheffield and Scunthorpe Line is a Parliamentary Service.
- It is 71.6 miles over 1 hour and 48 minutes, through seven stations of the Lincolnshire countryside, at an average speed of 40 mph.
- Currently, it runs once per day, which is not very ideal for a job, education, training, shopping or visiting grandchildren.
- A two-car version of 230001 could be ideal to perhaps do four round or five trips a day and level-up some of the poorer parts of the UK, that don’t even have a decent bus service.
- A similar two-car train could also serve the 45-mile round-trip Cleethorpes and Barton-on-Humber service.
I am sure that this train could start the right sort of rural or urban revolution.
Rail Vehicle Dispensation: Great Western Railway Class 230 Fast Charge Unit
The title of this post, is the same as that of this page on the UK Government web site.
The page is an interesting read, but I do feel, that it marks a big step on introducing the Class 230 trains on the Greenford Branch between West Ealing and Greenford stations.
I should say, that I’ve used the Class 230 trains several times and there are trains and platforms with worse passenger access problems on the UK network.
Battery-Powered Train Breaks Distance Record
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A battery-powered train has broken the world record for the longest railway journey on a single charge.
These three introductory paragraphs add more details.
The Great Western Railway (GWR) train – a specially adapted former District Line train – travelled overnight along a 200-mile (322km) route from Reading and back again, via London Paddington and Oxford.
It reached 140 miles (225km), breaking the record on Brunel’s Maidenhead Bridge at about 04:00 BST.
The previous record of 139 miles (224km) was set by German train company Stadler Deutschland in Berlin on 10 December 2021.
This was an impressive demonstration of the capabilities of battery-electric trains.
Will This Record Be Beaten?
200 miles is impressive, but there was also this paragraph in the article.
At the end of the journey GWR said there was a remaining battery charge of 22% which it estimated would have allowed the train to travel about a further 58 miles (93km).
So it looks like 258 miles should be possible.
Four other companies are also developing battery-electric trains.
- Alstom at Derby
- CAF at Newport
- Hitachi at Newton Aycliffe
- Siemens at Goole
- Stadler in Switzerland.
Note.
- All except Stadler have UK factories.
- Siemens and Stadler have delivered trains in Germany.
- This page on the Hitachi Rail web site is entitled Intercity Battery Trains.
- This page on the Hitachi Rail web site is entitled Hitachi Wins New UK Contract To Build Intercity Battery Trains. The customer is Grand Central Trains.
- Hitachi have been running a prototype for some months, in the UK.
The competition is hotting up and the record will certainly be soundly beaten.
GWR Battery-Powered Trains Could Be Used In Future
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Battery-powered trains could be used more frequently after a successful trial by Great Western Railway (GWR).
These three paragraphs give more details.
The rail company says using former underground trains and a rapid-charging system has shown the technology could replace its existing diesel fleet.
The year-long trial was held in west London but the trains will eventually be rolled out in the Thames Valley.
GWR says it can now prove the concept works and hopes to take the initiative to government.
A couple of weeks ago, I used similar trains between Wrexham Central and Shotton stations, which I wrote about in Vivarail Trains And Wrexham Central Station – 6th June 2025.
Changing For Chester At Shotton Station – 6th June 2025
From Wrexham Central station, I took the Borderlands Line to Shotton, where I changed to a train for Chester.
This Google Map shows the station.
Note.
- The station logo in the top-right corner of the map indicates the low-level station on the North Wales Coast Line.
- The second logo at the bootom of the map indicates the high-level station on the Borderlands line.
- It was quite a long walk between the two pairs of platforms.
- There were no lifts or facilities.
The Wikipedia entry for Shotton station gives this summary of future plans.
In March 2015 Network Rail published the draft version of their Welsh Route Study. It contained a proposal to build a new interchange station that would replace the existing High and Low Level stations, allowing for greater connectivity between the North Wales Coast Main Line and the Borderlands Line. The document recommended a transport planning study to establish the cost, feasibility and benefits of the proposed scheme.
In £2.1bn North Wales Rail Overhaul Plans Unveiled, match funding for step-free access at Shotton station is mentioned.
It certainly is a station in need of improvement. Especially, where step-free access is concerned.
It also needs a few more trains, as I waited an hour.
The Bay Platform At Greenford Station
These pictures show Greenford station.
I have some observations to make.
Electrification
Tests for the new battery-electric train would appear to be taking place soon, but there is no electrification or Vivarail/GWR Fast Charge system.
This leads me to the conclusion, that all charging will be done at West Ealing station.
What Length Of Train That Can Be Accommodated In Platform 2 At Greenford Station?
Consider.
- The two-car Class 165 train shown in the pictures is 47 metres long.
- FirstGroup’s test Class 230 train appears from a GWR video, to be three-cars, which would make it 54.663 metres long.
- The test Class 230 train would appear to be nearly eight metres longer, than the current train that works the route.
From the pictures it appears that there is sufficient space in the platform to accommodate the longer train.
Great Western Railway’s Battery Train Sets New Distance Record
The title of this post, is the same as that of this press release from Great Western Railway.
This is the sub-heading.
Great Western Railway’s innovative FastCharge battery trial has achieved another significant step – just days after laying claim to a battery train UK distance record without recharging.
These two paragraphs add more detail.
The train demonstrated its capability on Wednesday by travelling a UK record of 86 miles (138km) on battery power alone and without recharging.
Today the Class 230 battery train completed a 70-mile move from Long Marston to Reading Train Care Depot – using just 45 per cent of its battery capacity. GWR’s team of specialist engineers on board the train claim it could have travelled more than 120 miles on a single charge.
There is also this impressive video.
Note.
- In the video, the train is cruising at 36 mph.
- The top speed of the D78 Stock was 45 mph.
- The train looks in excellent condition.
This is a total game-changer for battery-electric trains in the UK.
The train makers, who have demonstrated battery-electric trains; Alstom/Bombardier, CAF, Hitachi, Siemens and Stadler will have to up their distances on battery power to at least 86 miles and possibly 120 miles, as who would want their new product to be outdistanced by second-hand forty-year-old upcycled London Underground trains?
I have some further thoughts.
The Trains Performance In The Real World
Dr. Simon Green, who is GWR’s Engineering Director, said this.
It’s also worth noting that in reaching the 86 miles on Wednesday, the train was operating in a real-world environment, at speeds of up to 60mph, stopping and starting over a hilly route, with elevation changes of up to 200m.
The train exceeded the 84 miles (135km) recorded by a Stadler Class 777 under test conditions in 2022 – believed to have been the greatest distance travelled by a battery train designed for the UK.
Note that the train was running at up to 60 mph.
Timings For The Mid-Cornwall Metro
This map shows the Mid-Cornwall Metro.
I have been looking at the Mid-Cornwall Metro and this service will share the Cornish Main Line with faster services between Par and Truro.
- Expresses and the Mid-Cornwall Metro will both stop at Par, St. Austell and Truro.
- Par and Truro is a distance of 19 miles.
- Expresses between Penzance and Plymouth take around 22-23 minutes to go between Par and Truro.
- This is an average speed of around 50-52 mph.
It looks to me, that there is scope for the Mid-Cornwall Metro and the express trains to run at similar speeds between Par and Truro.
- If the Mid-Cornwall Metro used Class 230 trains running on batteries, these trains should be fast enough to keep out of the way of the expresses.
- Par station has an island platform, where the Mid-Cornwall Metro uses one side (Platform 3) and expresses use the other (Platform 2).
Perhaps, if the timetable was something like this, it would give the best services to passengers.
- All expresses would use Platform 2, if they were stopping at Par station. The current track layout allows this.
- For Westbound passengers the Mid-Cornwall Metro would stop in Platform 3 and the express would stop in Platform 2, so that passengers going to beyond Truro on the Cornish Main Line could to the express on the other platform.
- Between Par and Truro, the Mid-Cornwall Metro would run a couple of minutes behind the express.
- Passengers for the Falmouth Branch could swap trains at Par on wait for the Metro at St. Austell or Truro.
- For Eastbound passengers, between Par and Truro, the Mid-Cornwall Metro would run a couple of minutes behind the express.
- At Par, the Mid-Cornwall Metro would stop in Platform 3 and the express would stop in Platform 2.
- The express would wait at Par for the Mid-Cornwall Metro.
- Passengers for Plymouth and London Paddington would change trains at Par for the express on the other platform.
- Passengers for the Newquay Branch on the express would swap trains at Par or wait for the Metro at St. Austell or Truro.
I suspect there are other patterns, but something like this will combine express services with the Mid-Cornwall Metro.
Simon’s Vision
Simon Green also says this about his vision of how the trains and the related FastCharge technology could be used.
GWR’s FastCharge technology has been designed to solve the problem of delivering reliable, battery-only trains capable of fulfilling timetable services on branch lines, eliminating the use of diesel traction and helping to meet the Government and wider rail industry’s target to reach net-zero carbon emissions by 2050.
The use of batteries for extended operation has typically been constrained by their range and meant widespread implementation has, until now, not been possible. It also negates the need for overhead electric lines which are expensive, time consuming to install and impact the landscape.
He’s judging the system as a whole, which is the only way to do it.
Where Could Class 230 Trains Be Used On The Great Western Railway?
These are a few ideas.
- Slough and Windsor & Eton Central – 2.8 miles – 3 cars – FastCharge at Slough
- Maidenhead and Marlow – 7.1 miles – 2 or possibly 3 cars – FastCharge at Maidenhead
- Twyford and Henley-on-Thames – 4.6 miles – 3 cars – FastCharge at Twyford
- Reading and Basingstoke – 15.4 miles – 3 cars – FastCharge at Basingstoke
- Weston-super-Mare and Severn Beach – 32.5 miles – 3 cars – FastCharge at Severn Beach
- Bristol Temple Meads to Avonmouth 8.9 miles – 2 cars – FastCharge at Avonmouth
Bourne End station, where there is a reverse may restrict the length of the service to Marlow.
Decarbonising The Mid-Cornwall Metro
Although the Mid-Cornwall Metro will probably run initially using what diesel multiple units, after a year or so, the route will be converted to zero-carbon operation.
Newquay To Falmouth Docks
This map shows the Mid-Cornwall Metro.
These are current timings.
- By train can take almost three hours with changes at Par and Truro.
- By car should take 45 minutes to drive the 24.4 miles according to Google.
Note.
- The train timings are for a typical British Rail-era Diesel Multiple Unit on the branches and something smarter between Truro and Par.
- A Day Return ticket would cost £8.90 without a Railcard.
- If there was a through train, that meant you didn’t have to change trains, I estimate that the time could be as low as one hour and 35 minutes.
I feel that most travellers, who had access to a car, would use that to travel between Newquay and Truro.
Newquay To Falmouth Docks By Electric Train
I have ridden in three battery-electric trains.
- Class 379 train – Manningtree and Harwich in passenger service.
- Class 230 train – Vivarail demonstration
- Class 777 train- Liverpool Central and Headbolt Lane in passenger service.
Note.
- All were mouse-quiet.
- There was no detectable difference, when running on battery power in the trains.
It is my view that battery-electric trains are no second-class solution.
Consider.
- Newquay and Par is 20.8 miles.
- Falmouth Docks and Par is 30.8 miles.
- Newquay and Falmouth Docks is 51.6 miles.
- The maximum speed between Par and Newquay is around 30 mph
- The maximum speed between Par and Falmouth Docks is around 50-70 mph
- There are twelve intermediate stations.
- There is a reverse at Par station.
- Charging would be easy to install at Falmouth Docks, Newquay and Par.
- In Par Station – 10th February 2024, I suggested that Par station could be fully-electrified, so that expresses could have a Splash-and-Dash on their way to London and Penzance. If all platforms at Par were electrified the Mid-Cornwall Metro trains could charge from the electrification, as they reversed.
There are two main ways that the Mid-Cornwall Metro might operate.
- There would be chargers at Newquay and Falmouth Docks and trains would shuttle the 51.6 miles between the two stations.
- There would only be charging at Par and trains would after charging at Par go alternatively to Newquay and Falmouth Docks.
The first might need smaller batteries and the second would only need one charger.
Newquay To Falmouth Docks By Hydrogen-Powered Train
There is only one hydrogen-powered train in service and that is the Alstom Coradia iLint, which is running in Germany.
I feel it is very much an interim design, as Alstom has taken a diesel-mechanical Lint train and swapped the diesel for a hydrogen-powered electricity generator and an electric motor.
But Alstom are putting together a hydrogen-powered train based on an Aventra.
Note.
- The train is three cars.
- I would envisage performance of the hydrogen train would be very similar to that of a similar battery-electric train.
- I wouldn’t be surprised that refuelling of the train would not be a problem, as with all the china clay working nearby, there may well be developments to use hydrogen in the industry to decarbonise the mining.
The Mid-Cornwall Metro and Alstom’s Hydrogen Aventra could be ideal for each other.
Conclusion
I believe, that although the Mid-Cornwall Metro will start operation with diesel multiple units, it will be running in a zero-carbon mode within a few years.
GWR Trialling Transformative Ultra-Rapid Charging Train Battery
The title of this post is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
Great Western Railway (GWR) has begun trialling a potentially groundbreaking battery innovation called FastCharge. If the trial is successful, it is hoped that the technology could transform branch line services and accelerate the decarbonisation of the network.
This is the first paragraph.
This innovative system, which has been developed over three years, eliminates the need for diesel trains on branch lines by powering battery-operated units with ultra-rapid charging. The system boasts an impressive 2,000kW charging capacity, eight times more powerful than a Tesla Supercharger, allowing trains to fully recharge in just 3.5 minutes at West Ealing station, the trial’s first real-world location.
I took these pictures of the trial installation at West Ealing station, this morning.
Note.
- Platform 5 is used by the trains to and from Greenford station.
- Two sets of charging rails have been installed between the rails, in Platform 5.
- The rails in the charging rails could be aluminium. This would not be surprising, as it is a good electrical conductor.
- The two shorter outside charging rails could be connected together.
- The yellow parts of the charging rails are plastic, so are probably for warning purposes.
- Two white containers have been installed alongside the track.
In Great Western Railway Updates EHRT On Its Upcoming Operational Trial Of Fast Charge Tech, I described the components of the Fast Charge system in this paragraph.
The Fast Charge system consists of three key components: retractable charging shoe gear, which is mounted to the underframe of the train; short (4m) charging rails mounted between the underframe of the train; and the Fast Charge Battery Bank (FCBB) installed beside the track, acting as an energy buffer between the train and the grid.
The charging rails are clearly visible in my images and the Fast Charge Battery Bank is probably in the white containers.
These are my thoughts.
The Engineering Is Of A High Quality
Or it certainly appears so from the platform and in the pictures, that I took.
How Much Energy Will Be Taken On Board at Each Charge At West Ealing?
According to the Rail Technology Magazine article, the Fast Charge Battery Bank will have to supply 2,000 KW for 3.5 minutes to fully-charge the train at West Ealing station.
This is 7,000 KW-minutes or 117 KWh.
In D-Train Order For Marston Vale Confirmed, this is said about the batteries on a Class 230 train.
- The train has four battery rafts, each with a capacity of 106 kWh
- Range is up to fifty miles with a ten minute charge at each end of the journey.
- Range will increase as battery technology improves.
I wonder if the Class 230 train, that will run between West Ealing and Greenford, will only have one 106 kWh battery.
- This will be less weight and therefor better acceleration.
- 117 kWh in the Fast Charge Battery Bank will be sufficient to fully-charge the single battery.
- The route is only five miles for a round trip.
I can see costs dropping.
What Batteries Will Be Used In The Fast Charge Battery Bank?
I think there are four main possibilities.
- New lithium-ion batteries
- Refurbished second-hand electric vehicle batteries
- New lead-acid batteries.
- It might be possible to use supercapacitors
Note.
- Lead-acid batteries can lose charge in cold weather.
- Supercapacitors don’t care about the weather.
- The weight of lead-acid batteries would not be a problem in a stationary application.
If there is only one battery on the train, I can see the supercapacitors handling it.
What Voltage Is Used In The Charging Rails?
Consider.
- The Vivarail Class 230 trains are built from redundant London Underground D78 Stock trains.
- The D78 Stock trains were built to run on London Underground lines, when that had voltages of 0 and 630 VDC.
- So I wouldn’t be surprised if the trains were designed around this voltage.
- If the charging rails worked at 630 VDC, then to have a 2,000kW charger, this would mean a charging current of 3175 Amps.
This would explain the fat cables connecting the charging rails to the Fast Charge Battery Bank.
An alternative voltage to use could be 3,000 VDC, as some trains are built to this voltage and therefor the electronics and transformers must be available. This would reduce the charging current to 667 Amps, which might be able to use smaller cables.
It may come down to what is convenient for the output voltage of the batteries.
Why Are There Two Sets Of Charging Rails?
They are both shown in this image.
Note.
- The two sets of charging rails are about forty metres apart.
- The Fast Charge Battery Banks are another twenty metres further on.
It’s not the layout you’d expect for running a single two-car train running every half hour.
But could it be that two separate sets of charging rails can operate a more frequent service with this layout of charging rails?
