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.
Smart Train Lease Aims ‘To Make Renting Trains As Easy And Simple As Renting A Car’
The title of this post, is the same as that of this article on Railway Gazette International.
These four paragraphs outline the scheme.
Siemens Mobility has established a leasing subsidiary that would enable train operators to use its Mireo Smart battery, hydrogen and electric multiple-units without needing to make long-term investment commitments.
Smart Train Lease GmbH would make available at short notice multiple-units already approved for operation. These could be short or medium-term leases, with services such as maintenance available as part of the package. The aim is to provide operators with an economical way to quickly and flexibly expand their fleets and try out more sustainable traction technologies.
‘We want to make renting trains as easy and simple as renting a car, and thus help accelerate the mobility transition’, the leasing company’s CEO Benjamin Dobernecker explained on February 14.
Smart Train Lease will initially operate in Germany, although it plans to expand throughout Europe in the medium term.
I like this idea and I think it will work.
Metier Management Systems And Artemis
When four of us started Metier Management Systems in 1977 to sell our mini-computer-based project management system; Artemis, we generally rented or leased our systems, although we did sell some as the years progressed.
- For a fixed fee per month, a company got a project management computer and all the software.
- The fixed fee included installation, first line support, training and software updates.
- We could also supply extra training and project management consultancy at appropriate rates.
- The only extra costs to the client were the electricity to power the hardware and the paper to put in the printer.
- We also allowed clients to convert leases into outright sales.
This simple sales model appealed to a lot of our clients.
- The cost of the system was easy to budget.
- Many of our clients were happy with leasing or renting computer equipment.
- As the system was desk-sized, it easily fitted the average office.
But the leasing model was very advantageous to us.
- Most of our clients were large high-value quality organisations like big oil companies, nationalised industries and engineering consultancies.
- Our Finance Director and our Bank Manager at Lloyds Bank devised a plan, whereby we bundled a number of high-quality leases together and sold the bundle to Lloyds Bank’s leasing company.
The money we received gave us a healthy cash flow.
- The cash flow was then used to fund Research and Development and to finance more sales.
- If say someone like BP or Shell should phone up or send a fax, wanting a system immediately, we were generally able to fulfil their request.
I am sure that Siemens Mobility will be using a similar model.
They will aim to have trains in stock to fulfil clients needs.
So if Deutsche Bahn phone up saying have you got a three-car battery-electric train that works with 15 KVAC and has a range of 100 kilometres for next Monday, Siemens Mobility can generally say yes.
What helps is that the modular Mireo Smart multiple unit comes in battery, hydrogen and electric versions.
Extras could include full servicing a driver.
So Siemens Mobility will plug the train together and deliver it.
How Would Siemens Use The Leasing Model In Great Britain?
Consider.
- There are a lot of routes that need to be decarbonised in Great Britain.
- Many of these routes have electrification at one or both ends.
- Often these routes terminate in a bay platform.
- On most of these routes a two-, three-, four- or five-car train will be sufficient capacity.
- In the Desiro City, Siemens have a train, that is acceptable to Great Britain.
- If routes in Great Britain are to be electrified, they must be electrified with 25 KVAC overhead wires.
- Trains would be 100 mph, so they wouldn’t be limited as to routes.
- A Mireo-B has a range of between 80-100 kilometres or 49.7-74.6 miles.
I am sure Siemens Desiro City or its European equivalent; Mireo can be developed into a family of trains suitable for GB!
- The basic train would be two driving cars.
- Length would be increased by coupling trailer cars between the two driving cars.
- Hydrogen power would be in one of the trailers.
- Batteries would be under an appropriate number of cars.
Battery trains would be able to use a simple automatic charger, similar to the one, that I described in GWR Trialling Transformative Ultra-Rapid Charging Train Battery.
An Example – Mid-Cornwall Metro
This map shows the Mid-Cornwall Metro.
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.
An Example – Uckfield Branch
The Uckfield branch is in Southern England.
- It is not electrified between Hurst Green Junction and Uckfield, which is 24.7 miles.
- There are eight intermediate stations.
- The line can accommodate ten-car trains.
There is space at Uckfield station for a charger.
Charging would be at Uckfield station and North of Hurst Green Junction, where it will use the existing electrification.
Conclusions
This leasing/rental model will surely encourage train operators to replace diesels with appropriate zero-carbon alternatives on routes that need to be decarbonised.
Ten Spanish Companies Join Forces To Apply Hydrogen Propulsion To A High-Speed Train For The First Time
The title of this post, is the same as that of this press release from Talgo.
These are the three bullet points.
- The Hympulso project is part of the Strategic Projects for Economic Recovery and Transformation (PERTES)
- A new technical car with hydrogen and batteries to be developed for a Talgo 250 train, allowing it to run on clean energy on non-electrified lines.
- The main partners are Talgo, Golendus, Ingeteam, Repsol, Sener and Optimus3D.
These are the first four paragraphs.
Ten Spanish companies have joined forces to design, build and install, for the first time in the world, a propulsion system based on renewable hydrogen fuel cells on a high-speed train. Under the Hympulso project, the companies will develop a set of technologies that can be applied to the Talgo 250 ‘all-terrain’ train, making it possible to electrify the rail network with energy generated entirely from renewable sources, even on lines without overhead power lines.
Led by Talgo, Hympulso also includes Golendus, Ingeteam, Optimus3D, Repsol and Sener as partners. Universidad Pontificia Comillas and Tecnalia are collaborators, while Adif is an observer. The initiative has received a grant of €6.5 million and is part of the Incentive Programme for the Innovative Value Chain and Knowledge of Renewable Hydrogen, as part of the Recovery, Transformation and Resilience Plan.
Hympulso will be comprehensive in nature: it will activate the entire renewable hydrogen value chain in the railway system, from production to consumption. The project will also make it possible to analyse the impact of the future transition on the various railway infrastructure assets managed by Adif, such as maintenance facilities or the track.
Thus, the project will result in a joint output of hydrogen supply installations adapted to railways -both mobile and static- and a pioneering prototype of a hybrid bimodal train for passengers with automatic track-gauge change, which will be able to run both on conventional and high-speed networks, using catenary supply when available, or hydrogen and batteries in those corridors that are not electrified.
This picture shows a visualisation of the train.
Note.
- There is a power car containing the hydrogen fuel cells and other gubbins behind the one or both locomotives.
- Hydrogen power is used, where there is no electrification.
- Talgo already make a high speed train with a diesel power pack, so engineering would only involve developing a new hydrogen power pack.
My only questions are.
- Do the trains come without gauge-changing?
- Could they be run on a typical UK rail line?
- Do they speak, Cornish, Gaelic and Welsh?
If the answer to all questions is yes, then this must be the ideal train for these routes.
- London Euston and Aberystwyth
- London Euston and Holyhead
- London King’s Cross and Aberdeen.
- London King’s Cross and Cleethorpes/Grimsby
- London King’s Cross and Inverness.
- London King’s Cross and Thurso/Wick.
- London Paddington and Carmarthen
- London Paddington and Penzance
Note.
- No more electrification on these routes would be needed.
- The trains could use High Speed Two to wherever it goes.
- The trains could do 140 mph on the Great Western Main Line, East Coast Main Line and West Coast Main Line.
Hympulso looks a very comprehensive, professional and practical plan, that could easily be adapted to the UK mainland.
Do Rolls-Royce mtu Have A Plan To Decarbonise Their Diesel Engines For Rail Applications?
Data Sheets For Rolls-Royce mtu Diesel Engines For Trains
These are data sheets for various Rolls-Royce mtu diesel engines that can be used in rail applications.
Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels
The title of this section, is the same as that of this press release from Rolls-Royce.
These four bullet points, act as sub-headings.
- mtu Series 1300, 1500 and 1800 engines already released; Series 1600 and 4000 to follow shortly
- Up to 90% CO2 savings by operating existing engines with Hydrotreated Vegetable Oil (HVO/renewable diesel)
- Locally emission-free operation possible in combination with mtu Hybrid PowerPack
- Field tests with DB Cargo and RDC Autozug Sylt
This is the first paragraph.
Rolls-Royce is taking a significant step towards even more climate-friendly rail transport with the release of mtu rail engines for use with sustainable fuels. With synthetic diesel fuels of the EN15940 standard, CO2 emissions can be reduced by up to 100 percent compared to fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially available today, reduces CO2 emissions by up to 90 percent. If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner. The mtu Series 1800 engines which are used in mtu PowerPacks, as well as Series 1300 and 1500 for locomotives and multi-purpose vehicles, are already approved for use with synthetic fuels such as HVO. Series 1600 and versions of Series 4000 engines will follow in the near future. The release of engines for climate-friendly fuels requires a series of tests and trials and Rolls-Royce has found strong partners for this activity. DB Cargo and RDC Autozug Sylt have already tested or are currently testing mtu Series 4000 engines with HVO in their locomotives.
How Does That Fit With The UK’s Population Of Rolls-Royce mtu Diesel Engines?
These classes of train have Rolls-Royce mtu engines.
- Class 43 power cars – 6V 4000 R41R
- Class 168 train – 6R 183 TD 13H
- Class 170 train – 6R 183 TD 13H
- Class 172 train – 12V 1800 R83
- Class 195 train – 12V 1800 R85L
- Class 196 train – 12V 1600 R85L
- Class 197 train – 12V 1600 R85L
- Class 800 train – 12V 1600 R80L
- Class 801 train – 12V 1600 R80L
- Class 802 train – 12V 1600 R80L
- Class 805 train – 12V 1600 R80L
- Class 810 train – 12V 1600 R80L
Note.
- Class 168 and 170 trains seem to be powered by older model Rolls Royce mtu engines.
- Class 180, 220,221 and 222 trains are powered by Cummins engines.
- I can’t find what engines power Class 805 and 810 trains, but it is reasonable to assume they have the same engines as the other Hitachi trains.
- As CAF are building LNER’s new tri-mode trains, I suspect these trains will also have Rolls Royce mtu engines.
It would appear that all the Rolls-Royce mtu rolling stock in the UK, with the possible exception of the Class 168 and 170 trains will be able to run on sustainable fuels.
Rolls Royce mtu And Hydrogen
This press release from Rolls-Royce is entitled Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen.
This is the first paragraph.
Rolls-Royce today announces that it has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion. These tests mark another important step towards the commercial introduction of hydrogen solutions to meet the demand of customers for more sustainable energy.
Engines of mtu’s 4000 family are used in Class 43 power cars, so surely these developments could lead to hydrogen-powered freight locomotives.
The picture shows a Class 43 power car at Glasgow Queen Street station.
Could Rolls-Royce mtu hydrogen power keep these iconic trains running for a few more years?
In ‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle, I look at Rolls-Royce’s Spirit of Innovation, which set the record for an electric vehicle at 555.9 km/hour.
As the InterCity125 already holds the record for the fastest diesel train, perhaps Rolls-Royce will attempt to set a record for the fastest hydrogen-powered train?
Decarbarbonising The CAF Class 195, 196 And 197 Trains
If Rolls-Royce mtu develop a hydrogen version of the 1800 diesel engine, then this could be used to fully decarbonise the CAF trains.
The operators may consider it’s not worth it and continue with using sustainable fuels.
But the possibility is surely there.
There must also be the possibility of developing a fuel cell replacement for the 1800 diesel, that can be slotted into the train.
Decarbarbonising The Hitachi Class 80x Trains
Hitachi are developing battery packs and the data sheet can be downloaded from this page on the Hitachi web site.
Decarbarbonising The CAF Tri-Mode Trains
I feel that as CAF usually use Rolls-Royce mtu engines, I suspect these trains will be designed, so they can be converted to hydrogen.
Conclusion
Rolls-Royce mtu appear to be on a path to decarbonise all their diesel engines.
Saudi Arabia Railways (SAR) Partners With Alstom To Showcase The World’s First Passenger Hydrogen Train In The Kingdom Of Saudi Arabia
The title of this post, is the same as that as this press release from Alstom.
These are the three bullet points.
-
World’s first hydrogen-powered train demo in the Middle East and Africa
-
Alstom’s Coradia iLint train will be used for the demo in the Kingdom
-
Saudi Arabia Railways (SAR) and Alstom highlight their commitment to sustainable mobility and carbon emission reduction in the Kingdom
These are the first two paragraphs.
Saudi Arabia Railways (SAR), in partnership with Alstom, a global leader in smart and sustainable mobility, will operate and demonstrate the world’s first passenger hydrogen-powered train, the Coradia iLint in Riyadh in the month of October. This ground-breaking demonstration marks the first-ever introduction of a hydrogen-powered train in the Middle East and Africa. The collaboration between SAR and Alstom signifies a strong focus by the Kingdom to identify and test innovative sustainable mobility solutions to reduce carbon emissions from transport and meet Vision 2030 targets set by the Kingdom’s leadership.
The planned demonstration follows the memorandum of understanding signed by SAR and Alstom in September 2022 to develop or adapt hydrogen solutions for the needs of the Kingdom. Alstom’s Coradia iLint, a hydrogen-powered passenger train will embark on a first-of-its-kind journey in the Kingdom, travelling 10 to 20 kilometres on Riyadh’s East Network’s Line 1 or Line 2.
Note.
- Hopefully, this is not just green-washing?
- Will the train be powered by green hydrogen?
At least, Alstom will get their trains tested in an atmosphere full of sand.
Hydrogen Rail Project Collaboration Launched By Angel Trains And University of St Andrews
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
Angel Trains, the UK’s largest rolling stock company, has partnered with the University of St Andrews to support an innovative hydrogen train project.
On Friday 29th September, an event was held to mark the donation of a hydrogen electrolyser to the university by Angel Trains. The electrolyser will form an integral part of the university’s ongoing, cutting-edge green hydrogen research.
This is the first paragraph.
The donation follows Angel Trains’ support for the delivery of Scotland’s first zero-emission hydrogen-powered train. The project entailed the conversion of a three-car Class 314 train to a hydrogen fuel cell electric powertrain. The electrolyser was key to enabling the trial to successfully demonstrate how a green-energy fuel cycle would work.
Hopefully, this initiative will lead to better use of hydrogen on the railways of the UK.
TransPennine Express To Stop Using Loco-Hauled Push-Pull Trains In December
The title of this post, is the same as that of this article on Railway Gazette.
This is the sub-heading.
TransPennine Express has confirmed that it will cease using its push-pull sets of Class 68 locomotives and MkVa coaches, previously designated Nova 3 sets, from the December 2023 timetable change.
These are my thoughts.
The Nova 3 Trains
Currently, the Nova 3 trains are made up from the following.
- 14 – Class 68 locomotives
- 52 – Mark 5a coaches
- 14 – Driving Van Trailers
Note.
- There have been complaints about the noise of the Class 68 locomotives at Scarborough and also at Marylebone with Chiltern Railways.
- The Class 68 locomotives could be switched to freight duties.
- The coaches are capable of 125 mph.
- A maximum of thirteen sets can be created.
- I suspect CAF wouldn’t object to being asked to build some more Mark 5a coaches and driving van trailers.
- The current fleet has a spare locomotive and a spare driving van trailer to allow for servicing.
All locomotives and coaches are a maximum of seven years old, so will have plenty of life left.
The Class 93 Locomotive
Rail Operations Group have ordered ten Class 93 locomotives, with twenty options, which have an impressive specification.
- Built by Stadler in Valencia.
- Same family as a Class 68 and 88 locomotive.
- Electric, diesel and battery power
- 110 mph operating speed
- Ability to pull passenger and freight trains.
- Delivery scheduled for 2023.
I believe that if the Class 68 diesel locomotive of a Nova 3 train, were to be replaced with a Class 93 locomotive, a very useful train would be created.
- It would be ten mph faster, than a Nova 3 train.
- It could use the diesel engine and the batteries to bridge gaps in electrification.
- By adding extra carriages it could be tailored to the needs of a route.
- In Vegetable Oil Fuelling Chiltern Railways Trains In UK First, I discuss how it might be possible to run all these locomotives on HVO to cut emissions.
- It could be quieter.
Could it be a simple way to reduce carbon emissions on a route?
The Successor To The Class 93 Locomotive
Stadler keep innovating in their designs for locomotives and are already building hydrogen-powered multiple units.
I can see Stadler coming up with a hydrogen-powered locomotive, with the following specification.
- In the same family as Class 68, 88 and 93 locomotives.
- Ability to do everything that Class 68, 88 and 93 locomotives can do.
- Ability to use 25 KVAC overhead electrification, where it exists.
- Ability to be able to be fitted with third-rail equipment, so it can use 750 VDC third-rail electrification, where it exists.
- At least a 110 mph operating speed.
- Range of at least 200 miles on hydrogen.
Stadler would sell a lot of these locomotives to decarbonise railways all over the world.
Possible Routes
These are possible routes for a rake of Mark 5a coaches hauled by a Class 93 locomotive or its zero-carbon successor.
Hull Trains
Consider.
- Hull Trains is an open access operator.
- Hull Trains currently have a fleet of five Class 802 trains, each of which have five-cars.
- A Class 93 locomotive has a power of 900 kW on diesel, whereas the Class 802 train has 2100 kW.
- The Class 802 train has nearly ten percent more capacity.
- In Ten-Car Hull Trains, I saw two Class 802 trains working as a pair. Does this indicate they have a capacity problem?
- Between Hull and the East Coast Main Line is only 36.1 miles and isn’t very challenging and I suspect could probably be easily handled by a Class 93-hauled rake of Mark 5a coaches.
- Adding extra coaches would not be difficult and would probably be less costly than with the more complex Class 802 trains.
- Hull Trains need to have a plan to decarbonise.
- HVO could be used to cut down emissions.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Would other operators of Class 802 trains like to increase their fleets, by adding Hull Trains’s five Class 802 trains?
TransPennine Express
Consider.
- TransPennine Express currently have four different fleets of trains, so it must cause problems with the allocation of drivers.
- The Class 397 trains are confined to the West Coast Main Line.
- So that leaves the bi-mode Class 802 trains and the diesel Class 185 trains to work the TransPennine routes.
The Wikipedia entry for the Class 802 train, gives more details of the plans for the Class 802 trains.
During October 2021, it was announced that TransPennine Express, Hitachi, and Angel Trains had agreed to convert one of the former’s Nova 1 trainsets into a battery hybrid train on a trial basis with the aim of supporting the technology’s further development. If successful, Hitachi and Angel Trains have proposed the retrofitting of the entire fleet. In January 2022, reports emerged that the Nova 1 fleet was operating under diesel power even when operating on entirely electrified sections of the East Coast Main Line on account of the insufficient power supplies present along the line; national railway infrastructure owner Network Rail is reportedly set to complete upgrades to the power supplies within two years.
The fleet is also set to benefit from the rollout of electrification under the Transpennine route upgrade scheme. The company’s management has noted that, in the event of largescale electrification being funded and implemented, the Class 802s could have some of their engines removed to reduce roughly 15% of their weight and thus raise their efficiency. Furthermore, Leo Goodwin, TPE’s managing director, has observed that while the Class 802s have an initial maximum speed of 125 mph (201 km/h), they have the capability of being modified for operating at 140 mph (230 km/h) if infrastructure upgrades were to permit such speeds at a future date.
Could an augmented fleet of battery-electric Class 802 trains handle the bulk of the TransPennine routes, with the shorter and unelectrified ones still being handled by the Class 185 trains?
These shorter routes are.
- Leeds and Huddersfield
- Manchester Piccadilly and Huddersfield
- York and Scarborough
Plans only exist to electrify Leeds and Huddersfield.
I suspect a few more battery-electric Class 802 trains would be needed.
Great Western Railway
Could a Class 93-hauled rake of Mark 5a coaches be used as a replacement for the GWR Castles or short-formation InterCity125s?
- They both have four passenger coaches.
- They are both 125 mph trains.
- A Class 68 locomotive could be used on routes without electrification.
- HVO could be used to cut down emissions.
- The Mark 5a coaches would probably be quieter, as they only have one diesel engine.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Alternatively, five-car Class 802 trains could be used as replacements for GWR Castles.
Great Western Railway also have the problem of decarbonising services between Bristol/Gloucester and Weymouth/Southampton/Portsmouth.
Great Western Railway look like they’re needing some innovative thinking.
I also suspect a few more battery-electric Class 802 trains would be needed for other routes.
Transport For Wales Rail
Transport for Wales Rail run a Premier Service between Holyhead and Cardiff using Class 67 locomotives and Mark 4 coaches.
According to the Wikipedia entry for Transport for Wales Rail, they have seven sets of 4/5 coaches to run this service.
If Transport for Wales Rail wanted to decarbonise this route, they would need to replace the locomotives for a zero-carbon unit.
Perhaps, their best solution, would be to wait until a suitable hydrogen-powered locomotive is available and buy seven rakes of new coaches with driving van trailers.
Grand Union
Grand Union has a detailed Wikipedia entry, where this is the first paragraph.
Grand Union is a prospective open access operator who are proposing to operate train services in the United Kingdom from England to Wales and Scotland. Grand Union is headed by Ian Yeowart, who founded previous open access operators Alliance Rail Holdings and Grand Central before selling both to Arriva.
That seems a sound foundation.
- They have permission to run trains between Paddington and Carmarthen starting in December 2024.
- They have also applied to run trains between Euston and Stirling.
- They are now backed by Spanish companies; Serena Industrial Partners and Renfe.
- They are proposing to use nine Mark 4 coaches hauled by Class 93 locomotives.
Consider.
- CAF has a factory in Wales.
- CAF has sold trains to Transport for Wales.
- The Mark 5a coaches will definitely be available by December 2024.
- Mark 5a coaches could easily be arranged as a rake of eight coaches and a driving van trailer.
- Grand Union is backed by Spanish companies.
I wouldn’t be surprised if Grand Union were to use sets of CAF-built Mark 5a coaches for their Carmarthen service. And later for their Stirling service.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Grand Central
Consider.
- Grand Central is another open access operator.
- Grand Central has a mixed fleet of twelve five-car diesel trains.
- These trains run under electrification on the East Coast Main Line.
- According to the Wikipedia entry for Grand Central trains, they have plans for expansion across the North and to and from London.
- Grand Central need to have a plan to decarbonise.
- HVO could be used to cut down emissions.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
South Western Railway
South Western Railway have an excellent fleet of new or nearly new trains, with the exception of the diesel Class 158 and Class 159 trains, that work services between Waterloo and Exeter trains via Basingstoke and Salisbury.
- Waterloo and Exeter is 172 miles.
- Only the 47.7 miles between Waterloo and Basingstoke is electrified with 750 VDC third-rail electrification.
- Train lengths vary between five and eight cars.
- The current trains date from around 1990 and must need replacing soon.
I wouldn’t be surprised that if after a rebranding with new trains, this could be a popular route.
A version of Hitachi’s ubiquitous bi-mode Class 802 could be used.
But.
- They would need to be ordered and built.
- The third-rail gear, would need to be developed and tested.
- Passengers would be travelling for over two and a half hours with underfloor diesel engines.
An alternative could be a Class 68-hauled rake of Mark 5a coaches.
- These trains would be available after release from TransPennine Express.
- They would run in TransPennine Express formation.
- Length could be adjusted by adding or removing coaches, if required.
- The noise is all in the locomotive, which is isolated from the passengers.
At some point in the future, the route could be decarbonised by swapping the locomotive for a hydrogen-electric locomotive with the ability to handle third-rail electrification.
ScotRail
ScotRail have a similar problem to Great Western Railway with their short-formation InterCity125s.
- They have 52 Class 43 locomotives and 120 Mark 3 coaches, which is probably enough for 24 trains.
- Scotland has substantial amounts of electrification.
- I feel that a Class 68-hauled rake of Mark 5a coaches would be a more than adequate replacement.
- Class 93 locomotives could be used where routes are partially electrified.
- Scotland is not going to be short of green hydrogen.
When a suitable hydrogen-electric locomotive is available, these trains can be decarbonised.
CrossCountry
CrossCountry have a fleet consisting of the following trains.
- 5 – 2+7 InterCity125 trains
- 7 – two-car Class 170 trains
- 22 – three-car Class 170 trains
- 34 – four-car Class 220 trains
- 4 – four-car Class 221 trains
- 20 – five-car Class 221 trains
Note.
- The fleet is all diesel.
- I’ll ignore the Class 170 trains in this analysis.
- The Class 220 and 221 trains often work in pairs to provide the required capacity.
So how could these trains be decarbonised?
- The InterCity125s and the Class 220 and 221 trains could be replaced by a locomotive-hauled rake of Mark 5a coaches of an appropriate length.
- Motive power could be provided by an appropriate Class 68 or 93 locomotive.
When a suitable hydrogen-electric locomotive is available, these trains can be fully decarbonised.
Decarbonisation Of UK Main Line Services
It is generally assumed that the railways of the UK will need to fully decarbonise if the UK and the constituent nations are going to meet their decarbonisation targets.
I believe that my analysis shows that decarbonisation of main line passenger services can be achieved by the purchase of two types of trains.
- Five-car bi-mode Class 802 trains or similar.
- Locomotive-hauled rakes of Mark 5a coaches of an appropriate length.
Note.
- The Class 802 trains would be mainly to augment existing Hitachi fleets.
- Some Class 802 trains would be fitted with batteries instead of diesel generators to handle gaps in the electrification.
- The rakes of coaches would be powered by an appropriate locomotive.
- The lengths of the rakes of coaches would be adjusted to meet the demand of each service.
Initially, the following locomotives would be used.
- Class 68 locomotives would be used on unelectrified lines.
- Class 93 locomotives would be used on full or partially electrified lines.
When the hydrogen-electric locomotives become available, these would take over the routes, which couldn’t be decarbonised by full electrification or by using a Class 93 locomotive.
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.
Hydrogen Trains Are To Roll Between Stade And Bremervörde
The title of this post is the same as part of the title of this article on Hydrogen Central.
The original title mentions Switzerland, but Bremervörde is in Germany to the North-West of Hamburg.
This map from OpenRailwayMap shows the route.
Note.
- Stade is in the North-East corner of the map and marked with a blue arrow.
- Stade station is on the Hamburg S-Bahn and has an hourly fast train between Hamburg and Cuxhaven.
- Bremervörde is in the South-West corner of the map, where the various routes converge.
- Bremervörde station is on the Buxtehude-Cuxhaven Line which is run by the hydrogen-powered Alstom Coradia iLint trains.
- Bremervörde appears to be, where the hydrogen-powered trains are serviced and refuelled.
- Currently, there are no passenger trains between Stade and Bremervörde, except at the weekends, when a heritage service called the Moor Express runs between Bremen Hauptbahnhof and Stade via Bremervörde.
- Freight trains also operate between Stade and Bremervörde.
At first sight it looks like the Stade and Bremervörde route, could be an ideal one to run with hydrogen-powered iLint trains.
- Servicing and refuelling of the trains could be shared with the existing Buxtehude-Cuxhaven service.
- The new service would probably need a few extra identical trains.
- The track is already in use, so probably wouldn’t need too much work.
- As some of the stations are in use by the Moor Express, there may not need to be too much work to bring them up to the required standard.
This re-opening, illustrates the advantage of having a fully-certified, independently-powered train, that can be deployed on non-electrified lines.
Key Mainline Testing Undertaken In Bi Modal Hydrogen Train Project
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is a key paragraph.
In the test, lithium-titanate batteries and the hydrogen fuel cells have been retro-fitted to a CAF Civia Class 463 commuter electric unit train. This then has the ability to create a hybrid powertrain which can run on electrified lines alongside standard lines.
This paragraph describes some of the testing.
The new power system has been integrated into the existing vehicle’s traction system and the current tests on the mainline follow closed track testing and static testing at CAF’s plant in Zaragoza. The mainline testing has taken place across lines in Zaragoza, Madrid and Galicia but the crucial test run for the new unit was on the Zaragoza-Canfranc line where it ran in both electric mode on the electrified line before switching to hybrid mode, combining the fuel from hydrogen fuel cells and batteries where needed.
It sounds like this is a better specified hydrogen-powered train than Alstom’s iLint.
