Is Alstom’s Proposal For A Service Between London Euston And Wrexham Part Of A Cunning Plan?
Alstom have built and introduced into service between Buxtehude and Cuxhaven in Germany, the Coradia iLint hydrogen-powered train. The prototype has performed demonstrations in Austria, Canada, The Netherlands and Saudi Arabia.
This picture shows a Coradia iLint in Germany.
In the UK, Alstom had a plan to convert redundant Class 321 trains into a fleet of hydrogen-powered trains called Breeze, which I wrote about in Hydrogen Trains Ready To Steam Ahead, in January 2019.
This visualisation is from Alstom.
I suspect it didn’t appeal to train companies, as no orders appear to have been received.
But you can’t criticise Alstom for not trying, as in November 2021, they signed an agreement with Eversholt Rail Group to develop a hydrogen-powered Aventra, which I wrote about in Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet.
This visualisation is from Alstom.
Visually, it looks just like any other Aventra and much better than the previous Breeze design.
In March 2018, I wrote Bombardier Bi-Mode Aventra To Feature Battery Power, which was based on this article in Rail Magazine.
These are a few points from the article.
- Development has already started.
- Battery power could be used for Last-Mile applications.
- The bi-mode would have a maximum speed of 125 mph under both electric and diesel power.
- The trains will be built at Derby.
- Bombardier’s spokesman said that the ambience will be better, than other bi-modes.
- Export of trains is a possibility.
- Bombardier’s spokesman also said, that they have offered the train to three new franchises. East Midlands, West Coast Partnership and CrossCountry.
Have Alstom looked at what they bought from Bombardier and decided the following train is possible, if they add some of their technology?
- A train the size needed by the customer, up to a length of at least ten cars.
- 125 mph under 25 KVAC overhead electrification.
- 100 mph with 750 VDC third rail electrification.
- Running on hydrogen away from electrification.
- 100 mph maximum speed running on hydrogen.
- A range of perhaps 500 miles, if it can emulate the hydrogen-powered Coradia iLint.
A train with this specification would have several applications in the UK.
- Fully-electric routes.
- Electric routes with perhaps a hundred miles of unelectrified track.
- Scenic routes, where the Nimbies wouldn’t like electrification.
These points should also be born in mind.
- There are now 110 mph Aventras in service with West Midland Trains on the West Coast Main Line.
- I recently came back from Cardiff to London in a twelve-car Class 387 train and there wasn’t too many unhappy passengers. It was certainly better than a rail replacement bus. I wrote about the trip in Cardiff To Reading In A Class 387 Train.
- Alstom believe you can certainly fit their hydrogen gubbins in an Aventra.
- The hydrogen gubbins appear to be from Cummins, who have a worldwide support network.
- Cummins can also supply complete hydrogen support systems. A truck can refuel the train, at one end of the route?
- Alstom have been doing the market research with the hydrogen-powered Coradia iLint, so I suppose they know what the market needs.
Could Alstom, with help from Cummins, have a zero-carbon 200 kph train and support systems, which has a hydrogen range of up to a thousand kms for export markets like the United States, Africa, Australia, India and South America?
Two big world-leading companies are surely better than one!
But Alstom has one big problem!
How do you fully test a 125 mph hydrogen-powered train?
- I know with aircraft, if you change the engine type on an existing aircraft, you only have to certify the engine and this is done on a Supplementary Type Certificate.
- Is it the same with trains, so a 110 mph Class 730 train, which is in service with West Midlands Trains, could be the basis of certifying a hydrogen-powered Aventra?
- The Coradia iLint was only a change from diesel to a hybrid hydrogen-electric engine, so was it certified this way?
- With the Coradia iLint, it seemed to go into service quite quickly, so did it do much of the testing in service?
I looks to me, that London Euston and Wrexham is an ideal route for a hydrogen bi-mode 125 mph train.
- The route has electrified sections, some of which have high operating speeds.
- The route has a convenient hydrogen supply from INEOS at Runcorn at the Northern end.
- Change between hydrogen and electric power would always take place in a station.
- A round trip needs less than 200 miles of running on hydrogen.
- South of Nuneaton, no hydrogen is used, so the train will be like a Class 730 train, that already uses the route.
- There are depots that can service Aventras on the route.
It is certainly a possibility, that the London Euston and Wrexham service will be used to test and showcase Alstom’s new Hydrogen Aventra.
Alstom Plans To Operate Its Own Passenger Train Service In The UK For The First Time
The title of this post, is the same as that of this press release from Alstom.
These two bullet points, act as sub-headings.
- Alstom is partnering with SLC Rail to form a new open access rail operation between North Wales, Shropshire, the Midlands and London
- Formal application now being submitted to the Office of Rail and Road (ORR) with passenger service sought from 2025
These are the first three paragraphs.
Alstom, global leader in smart and sustainable mobility, plans to operate a new passenger rail service across England and Wales. Working in partnership with consultancy SLC Rail, the open access operation will be known as Wrexham, Shropshire and Midlands Railway (WSMR).
As the country’s foremost supplier of new trains and train services, and a leading signalling and infrastructure provider, Alstom will operate its own rail service in the UK for the first time.
WSMR is seeking to introduce direct connectivity to and from North Wales, Shropshire, the Midlands and London that doesn’t exist today, linking growing communities and businesses, and making rail travel more convenient, enjoyable and affordable.
I can’t remember a service proposal being put forward by a train manufacturer since the privatisation of UK’s railways in the 1990s.
This is some more information and my thoughts.
The Route
This paragraph from the press release, describes the route.
The proposal envisages a service of five trains per day in each direction Monday to Saturday, with four travelling both ways on Sundays. Trains will stop at Gobowen, Shrewsbury, Telford Central, Wolverhampton, Darlaston, Walsall, Coleshill Parkway, Nuneaton and Milton Keynes on their journey between Wrexham General and London Euston.
Note.
- The proposed call at the new Darlaston station.
- The route is electrified between Euston and Nuneaton and Walsall and Wolverhampton.
- Much of the route North of Nuneaton is on tracks with a maximum speed of 70-80 mph.
The route is in these sections.
- Euston and Nuneaton – 96.7 miles – electrified
- Nuneaton and Walsall – 26.7 miles
- Walsall and Wolverhampton – 6.7 miles – electrified
- Wolverhampton and Shrewsbury – 29.7 miles
- Shrewsbury and Wrexham General – 30.3 miles
That is a total of 190.1 miles or 380.2 miles round trip.
I suspect that the service will need bi-mode trains.
Should The Service Call At Wellington?
This article on the BBC is entitled Rail Company Urged Not To Forget Wellington.
This is the sub-heading.
A rail company which is bidding to bring back a direct service between Shropshire and London has been urged not to forget a town.
These are the first three paragraphs.
Wrexham, Shropshire and Midlands Railway said it was preparing to apply to the government to run the service.
Trains would stop at Gobowen, Shrewsbury, Telford, Wolverhampton, Walsall, Coleshill and Nuneaton.
But Telford and Wrekin Council said the omission of Wellington as a stop was “short-sighted”.
Although Wellington is smaller than than Shrewsbury and Telford, it looks like a bit of analysis would provide a solution, that would be acceptable for all parties.
The Trains
In the press release, this phrase is used.
positive impact to both communities and the environment.
I can’t see any more electrification being erected on the route, so the trains will need to be bi-mode.
- Bi-mode diesel trains won’t have a positive impact on the environment.
- As the route between Wolverhampton and Wrexham General is not electrified, a battery-electric train would need a range of at least 60 miles or 120 miles for the round trip, if there were no charging at Wrexham General.
- But Alston are developing a Hydrogen Aventra, which I wrote about in Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet.
So could Alstom be using this route to trial and showcase their new Hydrogen Aventra?
I believe that the route will be very suitable for a hydrogen train.
- Changeover between electric and hydrogen power can always take place in a station.
- All hydrogen refuelling could be performed at one end of the route.
- A large proportion of the UK’s green hydrogen is produced by INEOS at Runcorn, which is less than fifty miles from Wrexham. A refuelling tanker could supply the train, as they do on some hydrogen routes in Germany.
- London has only small amounts of hydrogen infrastructure.
I suspect that refuelling will be done at the Wrexham end of the route.
This Alstom visualisation shows the train.
But it is only a three-car train.
- That is not a problem, as Aventras can be lengthened as required to the length required for the number of passengers.
- Some Aventras, like the Class 701 trains for South Western Railway, have even been ordered as ten-car trains.
- Two three-car trains may also be the ideal capacity, running as a six-car train.
So capacity will not be a problem.
If it is assumed that Alstom’s trains for the WSMR route, can use the overhead wires, where they exist, each trip between Wrexham General and London will require a total of 86.7 miles or 140 kilometres of running on hydrogen.
- A round trip will therefor require 280 kilometres of running on hydrogen.
- But between London Euston and Nuneaton, it will just be another electric train.
- I suspect that like the similar Class 730 train, it will be capable of 110 mph on the West Coast Main Line.
- Alstom’s Coradia iLint hydrogen train has a range of around a 500-800 kilometres on hydrogen.
- The WSMR trains will probably be 100 mph trains using hydrogen on a route, where that speed is possible.
So if a Hydrogen Aventra has a similar range to the Coradia iLint, it will be able to do two round trips before refuelling.
How Long Will The Service Take?
West Midlands Trains, who use the similar Class 730 trains take one hour and eleven minutes between London Euston and Nuneaton with a single stop at Milton Keynes Central.
As the WSMR trains will use the same route, I suspect the same time can be used.
As Nuneaton and Wrexham General are 93.4 miles apart a table can be created showing the time for the rest of the journey for different average speeds
- 50 mph – 1 hour 52 minutes – 3 hours 3 minutes.
- 60 mph – 1 hour 33 minutes – 2 hours 44 minutes.
- 70 mph – 1 hour 20 minutes – 2 hours 31 minutes.
- 80 mph – 1 hour 10 minutes – 2 hours 21 minutes.
Note.
- The first time is the Nuneaton and Wrexham General time and the second time is the overall journey time.
- Typical Avanti West Coast services via Crewe and a change at Chester, take between two-and-a-half and three hours.
I suspect, if the WSMR trains can keep the speed up through the Midlands, that two hours and 30 minutes could be possible.
Could The Hydrogen Aventra Run At 125 mph Under The Wires?
In March 2018, I wrote Bombardier Bi-Mode Aventra To Feature Battery Power, which was based on this article in Rail Magazine.
These are a few points from the article.
- Development has already started.
- Battery power could be used for Last-Mile applications.
- The bi-mode would have a maximum speed of 125 mph under both electric and diesel power.
- The trains will be built at Derby.
- Bombardier’s spokesman said that the ambience will be better, than other bi-modes.
- Export of trains is a possibility.
- Bombardier’s spokesman also said, that they have offered the train to three new franchises. East Midlands, West Coast Partnership and CrossCountry.
Have Alstom looked at what they bought from Bombardier and decided the following train is possible?
- Five-cars or what the customer needs.
- 125 mph under the wires.
- Running on hydrogen away from the wires.
- 100 mph on tracks without electrification.
Obviously, maximum speeds would depend on track limits.
Looking at 125 mph Avanti West Coast trains that have a Milton Keynes stop between London Euston and Nuneaton, they can reach Nuneaton ten minutes quicker than West Midlands Trains 110 mph Class 730 trains.
Two hours and 30 minutes between London Euston and Wrexham is looking increasingly possible.
Are we seeing an audacious proposal from Alston to sell new trains to CrossCountry and a host of other franchises?
Conclusion
London Euston and Wrexham would appear to be an excellent route for an Aventra-based hydrogen train.
- It can probably cruise at 110 mph on the West Coast Main Line between London Euston and Nuneaton.
- All switchovers between electrification and hydrogen can be performed in electrified stations.
- Hydrogen would only be used North of Nuneaton.
- The train can be refuelled at Wrexham General, with fuel supplied from INEOS at Runcorn.
- Given the typical 1000 km. range of hydrogen trains, a train can probably do three round trips without refuelling.
I can see this being a service with an excellent operational record.
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.
Chiltern Railways Seeks Proposals For Low-Emission Multiple-Unit Fleet
The title of this post, is the same as that of this article on Railway Gazette.
These are the first three paragraphs.
Chiltern Railways is seeking proposals for the supply of between 20 and 70 new or converted ‘low-emission’ multiple units.
The operator has called for ‘established’ rolling stock manufacturers, owners and modifiers to propose vehicles which would provide a ’meaningful’ reduction in the emissions and external noise compared to its existing diesel multiple-units, particularly in urban areas.
The envisaged five-year framework agreement has an estimated value of up to £400m, including supply and maintenance of the fleet, refuelling infrastructure and any depot modifications.
I have my thoughts.
Chiltern’s Rolling Stock
Chiltern Railways have two different types of rolling stock; diesel multiple units and rakes of coaches haled by diesel locomotives.
Chiltern’s Diesel Multiple Units
Chiltern has these diesel multiple units.
- Class 165 diesel trains – 28 x two-cars – 56 cars
- Class 165 diesel trains – 11 x three-cars – 33 cars
- Class 168 diesel trains – 9 x two-cars – 18 cars
- Class 168 diesel trains – 9 x three-cars – 27 cars
- Class 168 diesel trains – 10 x four-cars – 40 cars
Note.
- The trains were built between 1990 and 2004.
- The Class 165 trains are 75 mph units, whereas the Class 168 trains are 100 mph units.
- These total to 67 trains and 174 cars.
- This is an average train length of 2.6 cars.
Could a fleet of three-car low-emission 100 mph trains fit Chiltern’s requirements?
- They could work in pairs for six-car units for Birmingham Moor Street and Oxford.
- There may be a need for some four-car units.
But how will they be powered?
- Pure diesel will surely give out too many emissions!
- Would an mtu Hybrid PowerPack lower emissions enough?
- Could hydrogen-power be used, either with fuel-cells or a hydrogen internal combustion engine?
In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I wrote about Alstom’s proposed Hydrogen Aventra.
A version of these trains could be ideal, if Children could source the fuel economically.
Chiltern’s Diesel-Hauled Rakes Of Coaches
Chiltern have four rakes of Mark 3 coaches hauled by Class 68 locomotives.
These could be replaced by pairs of three-car low-emission’ multiple units.
Conclusion
A fleet of seventy three-car ‘low-emission’ multiple units, powered by hydrogen could be an innovative solution to the trains to run Chiltern’s services.
Could Hydrogen Trains Be Used As Pathfinders?
I must admit, I have a soft-spot for hydrogen transport, but I suppose most people look back on their first real job with a certain affection.
The only new hydrogen train under development for the UK Is the Alstom Hydrogen Aventra, which was announced in this press release in November 2021 and is entitled Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet.
Little is known about these trains, except what is in the original press release.
- Ten trains have been ordered.
- Each will be three-cars.
- Contracts will be signed in 2022, which didn’t happen.
Nothing is said about the following important features.
- What will be the operating speed?
- What will be the range on a fill of hydrogen?
- Will the trains have a pantograph, so they can be run on electrified lines with 25 KVAC overhead electrification?
All are important to train operating companies, who along with the Department for Transport need to be able to plan.
What Do I Mean By A Pathfinder?
I will look at the service between Reading and Basingstoke.
- It is 15.4 miles long.
- There are four stops, which will soon be five, with the addition of Reading Green Park.
- The line is partly-electrified.
- The service is only hourly and probably needed to be two trains per hour (tph).
- It is currently run by diesel trains.
In a decarbonised railway, there are only two options for running this line.
- Use hydrogen trains.
- Electrify and use electric trains.
Note.
- The cost of the two options will be different.
- If the hydrogen and electric trains are both quality trains, the passenger experience will be similar.
- To run two tph, track and signalling modifications will be needed.
- These modifications would also allow a two tph diesel service.
- There is no way to accurately determine, how many passengers would use a two tph hydrogen and electric service.
So suppose the following plan were to be enacted.
- Upgrade the track and signalling to allow a two tph service.
- Run the two tph service with diesel trains.
- Install hydrogen infrastructure for the route. In this case, it would probably be at the nearby Reading depot.
- Run the two tph service with hydrogen trains.
Hopefully on the completion of some months of successful running of the hydrogen trains, the number of passengers to be expected will have been predicted to a better accuracy than UK railways normally manage.
Then the decision between hydrogen and electric trains can be taken.
If hydrogen trains are the decision, the trains could stay in service, but if electrification is the solution, then once the electric service is operating, the hydrogen trains would move on to the next line to be decarbonised.
Why The Alstom Hydrogen Aventra’s Need To Be Able To Use Electrification
If you look at routes, where hydrogen trains could be used as Pathfinders, they could include, some partially-electrified routes.
- Reading and Bedwyn
- Reading and Oxford
- Reading and Gatwick
- London Bridge and Uckfield
- Ashford and Eastbourne
- Preston and Blackpool South
- Wisbech and Cambridge
- Dereham and Norwich
- Basingstoke and Exeter
- Romsey and Salisbury
- York and Scarborough
This list includes both routes with both types of electrification; 25 KVAC overhead and 750 VDC third rail.
But if the electrification is there and not used, the exercise will be labelled as greenwashing, by some.
Chiltern Electrification Alternatives Studied
The title of this post, is the same as that of this article on Railway Gazette.
These are the first two paragraphs.
Chiltern Railways is working to present the Department for Transport with options for a fleet renewal programme, with London Marylebone being the only non-electrified London terminal and pressure for the withdrawal of diesel trains continuing to mount, particularly from local residents.
Industry insiders report that this could see at least the 39 two and three-car Class 165 diesel multiple-units replaced.
Note.
- The Class 165 trains were built in 1990-1992 and refurbished around the turn of the century.
- Chiltern Railways have 28 two-car and 11 three-car Class 165 trains.
- Chiltern Railways also have ten similar two-car, nine three-car and nine four-car Class 168 trains.
- In addition, Great Western Railway has 20 two-car and 16 three-car Class 165 trains, and 23 Class 166 trains.
- The Class 165 and Class 166 trains are 90 mph units, whereas the Class 168 trains are 100 mph units.
As Chiltern’s study would appear to rule out electrification, could all of these trains be replaced with an appropriate number of a new class of 100 mph zero-carbon independently-powered multiple units?
In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I talked about a proposed hydrogen train fleet.
These trains are described as three-car in Alstom’s press release.
- Most Aventras are 100 mph trains.
- They could easily be lengthened to four cars by the addition of an extra car.
- It may even be possible, that these trains could be fitted with a pantograph for working on electrified lines.
The only problem, I can envisage, is that a two-car version might not have enough space for the hydrogen and electrical gubbins.
Chiltern’s Locomotive-Hauled Mark III Stock
Greater Anglia have replaced locomotive-hauled Mark III stock with multiple units and it appears to have been successful.
Could Chiltern’s locomotive-hauled Mark III stock be replaced by six-car hydrogen-powered Aventras, with a long-distance interior?
Other Routes
Alstom and Eversholt Rail announced their agreement in November 2021.
Since then, I have written these posts, where the proposed Alstom Hydrogen Aventra could have an application.
- Adding Buxton And Manchester Piccadilly To The Bee Network
- ‘Castle’ HSTs To Be Withdrawn By Great Western Railway
- Proposals Submitted To Create Darlington To Dales Rail Link
- Alstom Hydrogen Aventras And Teesside
- Alstom Hydrogen Aventras And The Reopened Northumberland Line
- Alstom Hydrogen Aventras And Extension Of The Birmingham Cross-City Line
- Alstom Hydrogen Aventras And Great Western Branch Lines Between Paddington And Oxford
- Alstom Hydrogen Aventras And The Uckfield Branch
Note.
- A two-car version would surely increase the number of applications.
- A 110 mph capability would allow the trains to mix it with high speed trains on fast lines.
- Bombardier proposed a 125 mph bi-mode Aventra. Could this be achieved with hydrogen power?
I feel the eight applications, I listed, could be the start of something a lot bigger.
Conclusion
Alstom and Eversholt Rail Group appear to have done their research.
Adding Buxton And Manchester Piccadilly To The Bee Network
This article on the Railway Gazette has a list of the lines, that will be transferred between Northern Rail and the Bee Network.
Included in the list is this line.
Buxton And Manchester Piccadilly
I think this route would be the following.
- The Southern terminus would be Buxton.
- The Northern terminus would be Manchester Piccadilly.
- Intermediate stations would be Dove Holes, Chapel-en-le-Frith, Whaley Bridge, Furness Vale, New Mills Newtown, Disley, Middlewood, Hazel Grove, Woodsmoor, Davenport, Stockport, Heaton Chapel and Levenshulme.
- he route is fully electrified with 25 KVAC overhead between Hazel Grove and Manchester Piccadilly.
- Most of the route has a range of operating speeds. up to 90 mph.
- The distance is 19 miles
- Trains take 62 minutes
- Trains are often two-car Class 150 trains working as a pair.
- The Buxton Line is one of the stiffest routes on the UK rail network.
The route is the same as the current Northern Trains service.
This is my thought.
Trains
I think there are three choices.
- Electrify the line fully and use 100 mph electric trains like Class 331 trains.
- Use 100 mph battery-electric trains, with large enough batteries to climb to Buxton.
- Use 100 mph hydrogen-electric trains, with enough power on hydrogen to climb to Buxton.
Note.
- The current diesel trains could be used until a zero-carbon solution is delivered.
- 100 mph trains would be needed because of the 90 mph section around Stockport.
- The stiffness of the line makes the choice difficult.
- Regenerative braking would allow trains to coast down the hill.
- Battery-electric trains would not need charging at Buxton.
I’m sure that the deal that will be setting up the Bee Network, would have a plan for the Buxton Line.
‘Castle’ HSTs To Be Withdrawn By Great Western Railway
The title of this post, is the same as that of this article on Rail Advent.
This quote from a GWR spokesman, sums up the action that will be taken.
The Castles were always designed to be a temporary measure on the Cardiff to Penzance route. We expect to replace the Castle Class trains on a phased basis over the next couple of years, bringing customers the benefit of more modern trains that will reduce both cost and carbon emissions across the route.
These are my thoughts.
Could The Engines In The Power Cars Be Replaced With Modern Carbon-Neutral Engines?
This would be an alternative way to solve the decarbonisation problem.
It would also mean that other applications of the Class 43 power cars, like ScotRail’s Inter7City trains, Cross Country’s HSTs and Network Rail’s New Measurement Train would have a decarbonisation route,
In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, Rolls-Royce mtu outline their route to decarbonise rail engines using sustainable fuels.
This was the first paragraph of my conclusion in the linked article.
Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.
The Class 43 power cars have Rolls-Royce mtu Series 4000 engines, which will soon be available to run on sustainable fuel.
I think as a possible fall-back, one Class 43 power car should be converted to carbon neutral.
Could The Engines In The Power Cars Be Replaced With Modern Hydrogen Engines?
I looked at this in Will We See Class 43 Power Cars Converted To Hydrogen?.
I came to the conclusion, that this might be possible and said this.
It would be the ultimate Roller.
But then Rolls-Royce know about winning battles with large internal combustion engines.
The Option Of New Trains
This quote from a GWR spokesman was fairly definite about new trains, when they said.
The Castles were always designed to be a temporary measure on the Cardiff to Penzance route. We expect to replace the Castle Class trains on a phased basis over the next couple of years, bringing customers the benefit of more modern trains that will reduce both cost and carbon emissions across the route.
What trains could replace the Castles?
- The Cardiff and Penzance route is just short of 250 miles or roughly 400 kilometres.
- Only about 30 miles at the Cardiff end is electrified.
- Trains would need to be able to handle 25 KVAC overhead electrification.
- 125 mph trains will be needed at the Cardiff end.
- Four or five passenger cars will be needed.
- Currently, there are twelve Castles, so I will assume twelve new trains.
As these trains will be lasting up to forty years, they must be zero-carbon, which must mean battery-electric or hydrogen.
Charging Battery-Electric Trains
Consider
- Bristol Temple Meads, Exeter St. Davis and Plymouth are large stations with several platforms. I suspect that a number of Furrer + Frey’s charging stations can be installed along the route.
- The timetable would be adjusted to allow trains to be charged as they stopped to set down and pick up passengers.
- Trains would dwell in the station and then use their 125 mph performance to regain the time.
- I’ve also found a Penzance to Cardiff service, that stopped at Plymouth for fourteen minutes, which is more than enough to charge the batteries.
- Regenerative braking to the batteries would further eke out the range.
- There might also be some extra electrification around Bristol or Exeter.
- Some form of charging would be needed at Penzance.
Note.
- Putting up electrification may mean that it will delay the new trains for a few years.
- Charging stations along the route could probably be installed to a tight timetable.
I believe that with some top-class work, by battery and charger manufacturers, that a battery-electric train could be developed that could run between Cardiff and Penzance.
Thoughts On Hydrogen
Consider.
- The Alstom Coradia iLint train has a range of about 1,000 km. on hydrogen.
- Companies like Airbus, Boeing and a host of rocket makers will improve the storage and safety of hydrogen.
- A range of a 1,000 km. would allow refuelling at one end of the route.
- Trains could be multiple units or a hydrogen-electric locomotive pulling a rake of coaches with a driving van trailer.
I feel that hydrogen would be very feasible as a power source.
Alstom Could Offer A Hydrogen Aventra
Consider.
- Alstom are developing a hydrogen-powered Aventra.
- Bombardier were offering a 125 mph Aventra.
- A typical Aventra like a Class 720 train seats a hundred passengers a car.
A hydrogen Aventra would be feasible.
Hitachi Could Offer A Battery-Electric Or Hybrid AT-300
In 2021, in Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%, I wrote about the announcement of the Hitachi Intercity Tri-Mode Battery Hybrid Train, which is shown in this Hitachi infographic.
Note.
- Batteries replacing an engine to cut fuel usage and reduce carbon emissions.
- First time a modern UK intercity train, in passenger service, will use alternative fuel.
- These Hitachi trains use mtu engines, so I suspect they will be switched to sustainable fuel like HVO.
- The trains are 125 mph and 140 mph with the latest digital signalling.
- Great Western Railway already have 58 five-car Class 800/802 trains and 35 nine-car 800/802 trains.
- They would not need any changing stations or other infrastructure changes.
- Staff retraining would be minimal.
Testing of the prototype of these trains must be getting very close or even underway.
Stadler Could Offer A Battery-Electric Flirt Akku
Consider
- Stadler have run a Flirt Akku on batteries for 243 km.
- Flirt Akkus will go into service soon.
- Flirts have been designed for 125 mph running.
With charging at Cardiff, Bristol, Exeter, Plymouth and Penzance, I believe a Flirt Akku could handle the route.
Are Hitachi Home And Hosed?
I have a feeling that the announcement has been made about retiring the Castles as the prototype Hitachi Intercity Tri-Mode Battery Hybrid Train is under test and is performing well.
So I wouldn’t be surprised to see an order for twelve more Class 802 trains soon.
Proposals Submitted To Create Darlington To Dales Rail Link
The title of this post, is the same as that of this article on the Durham County Council web site.
These paragraphs outline the proposals.
The proposals will focus on development of the Darlington-Dales corridor, improving the connectivity of towns and villages along the Weardale line. It will also review the possibility of providing a link to Crook.
This new rail link would support economic development along the Darlington-Dales corridor, helping to attract visitors and boost spend in these areas by connecting tourism sites including Hamsterley Forest, Bishop Auckland town centre, the Durham Dales, and the Weardale Railway.
The enhanced rail connectivity would also enable residents to access wider education and job opportunities, while reducing the environmental impact of the county’s transport system by providing an alternative to cars.
It looks at first glance to be practical proposals, that could be easily achieved without spending a fortune.
As Teesside has a plentiful supply of hydrogen and is even planning a depot for hydrogen trains, what would new Alstom Aventra hydrogen trains between Weardale and Saltburn via Darlington, do for tourism in the area?
BP Plans To Turn Teesside Into First Green Hydrogen Hub
The title of this post, is the same as that of this article in The Times.
This is the first paragraph.
BP plans to build Britain’s biggest “green hydrogen” facility on Teesside to produce the clean fuel for use in new hydrogen-powered lorries and other transport.
Note.
The plans appear to be ambitious starting with a £100 million investment to build a 60 MW electrolyser by 2025, which would rise to as much as 500 MW by 2030.
The electrolyser will be paired with an upwards of a billion pound one gigawatt facility called H2Teesside, that will produce blue hydrogen.
I think there could be more to this than meets the eye.
Using The Carbon Dioxide Rather than Storing It!
I followed the carbon dioxide pipe from the CF fertiliser plant on Teesside using Google maps after seeing a film about it on the BBC. It goes to the Quorn factory and a massive greenhouse. I do wonder, if BP is talking to other companies, who also have a need for large quantities of good quality carbon dioxide.
One could be an Australian company, called Mineral Carbonation International, who have developed a process to convert carbon dioxide into building products like blocks and plasterboard. MCI won a prize at COP26, so could BP be looking at integrating one of these plants into their complex on Teesside?
The Electrolysers
Will BP be purchasing their electrolysers for green hydrogen from ITM Power in Sheffield?
This press release from ITM Power is entitled 12MW Electrolyser Sale.
The customer is not named, but could this be a starter kit for BP?
Alstom’s Hydrogen Aventras
In Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet, I came to this conclusion.
This modern hydrogen train from Alstom is what is needed.
I also felt there could be three similar trains; electric, battery-electric and hydrogen, which would help operators hedge their bets on what type of traction to use.
Teesside must be one of the more likelier places where the Hydrogen Aventras will be carrying passengers.
I wrote about this possibility in Alstom Hydrogen Aventras And Teesside.
A deal between BP and Alstom would surely be in the interest of both companies.
- Alstom would get a local hydrogen supply.
- BP would get a first sale.
- BP would get excellent publicity and a local demonstration of the possibilities of hydrogen.
It might even be possible to supply the hydrogen by pipeline.
