Scotland To Get New Intercity Fleet
The title of this post is the same as that of this press release from Transport Scotland.
These eight paragraphs make up the body of the press release.
The Scottish Government announced today that procurement will begin to replace the trains in its Intercity fleet.
The procurement will seek a replacement for the High Speed Train (HST) fleet of 25 trains which operates on its InterCity routes between Glasgow, Edinburgh, Aberdeen, and Inverness.
Cabinet Secretary for Transport, Fiona Hyslop said:
“Resilient, reliable ScotRail services are key to encouraging more people to choose to travel by train for work, leisure and learning.
“Over 4 million passengers travelled on InterCity trains between our key cities in the last year – we want to encourage even more people to do so. This procurement will enable us to replace the current Intercity fleet with trains which provide improved facilities and accessibility.
“Any replacement fleet is expected to be more energy efficient and therefore will significantly reduce emissions, reduce operating costs and be more in line with current passenger expectations, including for accessibility. The procurement process ensures Scottish suppliers will be able to offer to provide their services to potential bidders.
“This latest milestone in our rolling programme of decarbonisation will ensure the reliability of our Intercity routes for the long-term, making Scotland’s railway a more attractive and greener travel choice.”
Further details on this announcement will be shared when the contract is awarded in 2025. It is also expected that the refreshed Decarbonisation Action Plan will be published in Spring 2025, and this will detail updated targets for replacing ScotRail’s existing diesel fleets.
It is a press release full of good intentions, but very few facts.
Is this what Scots get from their political party?
I have a few questions.
Will The Trains Be Built In The UK?
This must surely give some advantages, but will it get the best trains at the best price?
What Will Be The Number And Capacity Of The Trains?
Transport Scotland could go for a like for like number and capacity replacement.
- But there have been capacity problems in Scotland, which have meant using diesel Class 153 trains as baggage cars.
- They might also want to add extra services.
- Will they replace the train lost at Stonehaven?
They could add a few options.
Other Companies May Need Similar Trains
Consider.
- GWR will need to replace their similar Castles.
- CrossCountry will need new trains.
- Grand Central will need new trains.
- South Western Railway may need new trains for services between Cardiff and Devon.
- Transport for Wales may need new trains.
Hull Trains and Lumo have recently ordered a selection of new Hitachi Class 802 and 803 trains, which I wrote about in Fourteen New Trains To Drive First Rail Open Access Growth.
I can see an argument for buying more Hitachi Class 80x trains, as it will surely save Great British Railways costs in the long time.
Should The New Trains Be A Forever Solution?
When British Rail electrified to Brighton, Crewe, Edinburgh, Glasgow, Leeds, Liverpool, Manchester, Newcastle, Norwich, Portsmouth, Southampton, Weymouth and many other places from London, they saw it as a mode of traction, that would be used forever.
As the trains wore out or got outdated, they would be replaced with trains, which at least could run using the same mode of traction.
Generally, on electrified routes, when British Rail’s electric trains have been replaced, they have been replaced by more modern new electric trains.
The one major exception was on the East Coast Main Line where some InterCity 225 trains were replaced with Hitachi Class 800 and Class 802 diesel bi-mode trains.
But as the Class 800 and Class 802 diesel bi-mode trains were also replacing InterCity125 trains, they were a pragmatic replacement.
The Hitachi trains can be considered a Forever Solution, as bi-mode trains will always be able to work some routes that will never get electrified.
But Hitachi are developing the successor to their diesel bi-mode train, which is the tri-mode train, capable of running on electrification, diesel or battery power.
- Diesel power-packs can be swapped for battery packs.
- The battery packs have the same weight and power as a diesel power-pack.
- Existing diesel bi-mode trains can be converted to tri-mode or battery-electric bi-mode trains.
- A range of over forty miles on a single battery pack has been demonstrated.
Could Hitachi tri-mode trains be The replacements for the Inter7City trains?
Will Some Trains Have A Battery Electric Capability?
I very much believe so, as some routes in Scotland could be decarbonised by battery-electric trains.
What Top Speed Would The Trains Have?
Most of the routes in Scotland, where new modern quality rolling stock is needed, has a top speed of less than 100 mph, but in places the top speed is 125 mph.
I suspect, if trains can run at 125 mph in the places, where it is allowed, could probably save a few minutes on journey times.
Take the Borders Railway.
- The electrification runs out at Brunstane. Batteries would be charged between Edinburgh and Brunstane using the existing electrification.
- To go from Brunstane to Tweedbank and return to Brunstane is 63 miles.
- To work the Borders Railway would need a battery range of 63 miles.
I suspect every route in Scotland could have an electrification strategy for use with battery-electric trains. Some of which would have short lengths of extra electrification.
What Lengths Would The Trains Be?
In my example I used the Borders Railway.
A typical service is run by a three-car Class 170 train or two such trains running as a pair.
Perhaps, a single four- or five-car train could work the service all day and still provide enough capacity?
Conclusion
I believe, that Scotrail services could be electrified line-by-line.
Some lines would need more or longer trains and an update to the electrification.
Are Scotrail Going To Replace The Inter7City Trains With Hydrogen-Powered Trains?
This article in The Times is entitled The Caley Is Ready To Roll With New Venture Building Trains.
I feel that this is one of the most significant paragraphs in the article.
ScotRail has indicated that it wants to replace nearly two thirds of its fleet with new, low-carbon rolling stock between 2027 and 2035, comprising about 675 carriages in total, with an initial core order of 64 four and five-car units. A spokesman confirmed: “We are working on a business case that will go to the Scottish government for the procurement of a new suburban train fleet.”
The current Scotrail fleet includes.
- 25 Inter7City trains which comprise 52 Class 43 power cars and 120 Mark 3 carriages – Diesel – 120 cars – 1975
- 5 Class 153 trains – Diesel – 5 cars – 1987
- 42 Class 156 trains – Diesel – 84 cars – 1987
- 40 Class 158 trains – Diesel – 80 cars – 1987
- 30 Class 170 trains – Diesel – 90 cars – 1998
- 21 Class 318 trains – Electric – 63 cars – 1985
- 34 Class 320 trains – Electric – 66 cars – 1990
- 40 Class 334 trains – Electric – 120 cars – 1999
- 38 Class 380 trains – Electric – 140 cars – 2009
- 70 Class 385 trains – Electric – 234 cars – 2015
Note the last three fields are the traction type, total number of cars and the build year of the first train.
I will split these trains into four groups.
- Inter7City – Diesel – 25 trains – 120 cars
- BR Diesel – Diesel – 117 trains – 259 cars
- BR Electric – Electric – 55 trains – 129 cars
- Modern Electric – Electric – 148 trains – 494 cars
Note.
- This is a grand total of 345 trains and 1002 cars.
- Ignoring the modern electric trains and the total is 197 trains and 508 cars.
- The total for diesel trains is 142 trains and 359 cars.
- As Great Western Railway have withdrawn their similar GWR Castles, there must be reasons for Scotrail to do the same.
I will now look at replacement strategies, based on this statement from Scotrail.
ScotRail has indicated that it wants to replace nearly two thirds of its fleet with new, low-carbon rolling stock between 2027 and 2035, comprising about 675 carriages in total, with an initial core order of 64 four and five-car units.
I would expect 675 carriages would be about 232 trains, if the current average train length of just under three cars is carried over.
The Effect Of 675 New Carriages
Assuming that no modern electric trains were replaced, this would create a fleet size of at least 1169 carriages.
This would be a sixteen percent increase in carriages, which would be welcome news for some rail users.
The Initial Core Order Of 64 Four And Five-Car Units
All we know of this order, is the number of trains and that they will be new and low-carbon, according to indications from Scotrail.
Low-carbon would mean one of these traction options.
- Electric trains with full electrification.
- Battery-electric trains with partial-electrification.
- Hydrogen-powered trains.
Note.
- The heritage Taliban would object violently to full electrification of some historic routes.
- UNESCO would probably remove the World Heritable Site status to the Forth Bridge if it were to be electrified.
- Scotland is developing a hydrogen infrastructure.
- Hydrogen-powered trains have long ranges in the order of a thousand kilometres.
- Hydrogen-powered trains are essentially electric trains with a hydrogen fuel-cell to provide electricity as needed.
- Hydrogen-powered trains would need very little new infrastructure, except for a network of refuelling points across Scotland.
- Well-designed battery-electric and hydrogen-electric trains, should be very quiet and comfortable for passengers.
As an engineer, I would choose hydrogen-power for the initial core order.
Where would the initial core order be deployed?
Twenty-five would be used to replace the carbon-emitting elderly Inter7City trains.
These routes could probably handle the other forty.
- Aberdeen and Inverness
- Edinburgh/Glasgow and Aberdeen.
- Edinburgh/Glasgow and Inverness.
- Glasgow and South Western Line
- West Highland Line.
Note.
- A lot of diesel trains would be retired.
- Trains could be designed, for tourists with proper cycle spaces.
- The West Highland Line would get the five-car trains it needs.
This would be a good start.
Conclusion
It looks to me, that the Inter7City trains will be going and will be replaced by new trains.
But will Scotland take the great leap forward and power the new trains by Scottish hydrogen?
What Will Be The Power Unit In LNER’s New CAF Tri-Mode Trains?
There is a short article in the January 2024 Edition of Modern Railways, that is entitled New LNER Fleet To Have Joint Line Capability.
This is said about the diesel engines in the new CAF tri-mode trains.
CAF will supply 10×10-car trains with overhead electric, battery and diesel capability, financed by Porterbrook. The inclusion of diesel engines as part of the winning bid, rather than a straightforward battery-electric unit, has surprised some observers, but LNER’s specification was that the fleet should have sufficient self-powered capability to cover the length of the joint line, which is approximately 90 miles. This is currently to be considered to be beyond the scope of battery-power alone, although as the technology evolves diesel engines could be replaced by batteries. The configuration of diesel engines and batteries within the sets has yet to be decided.
As the paragraph says that the diesel engines can be replaced by batteries and the trains are from CAF’s modular Civity family, it sounds like CAF are using a modular power system.
The CAF Class 195, 196 and 197 diesel multiple units, that are used in the UK, use mtu Railcar Power Packs, which are shown on this web page.
mtu are a Rolls-Royce subsidiary.
mtu also make a Hybrid Power Pack, which is shown on this web page.
This is the sub-title on the web page.
Individual hybrid drive with a modular design
Underneath is this sub-heading.
It takes revolutionary thinking to develop a smart rail drive system like the Hybrid PowerPack. Find out what makes mtu different, and why our Hybrid PowerPack brings added value to operators while benefiting passengers and the environment alike.
These paragraphs describe the mtu Hybrid PowerPack.
The Hybrid PowerPack was developed from the successful mtu underfloor drives: Tried and tested mtu PowerPacks were modified and equipped with additional components and functionalities in order to integrate hybrid technology. The mtu hybrid concept consists of a modular kit with a variety of drive elements. It satisfies all existing railway standards and can be arranged according to customer specifications.
Thanks to its compact design and the use of power-dense electrical machines, the Hybrid PowerPack can be easily integrated in the existing installation space under the floor, both in new rail vehicles or for repowering. mtu EnergyPacks – the energy storage – can be positioned at various places in the vehicle: on the roof or underfloor. The modular design creates great flexibility for operators who are planning new diesel hybrid vehicles or want to convert existing vehicles.
Based on specifications for the hybrid train and the profile of the planned routes, mtu can simulate the lifecycle costs (capital, maintenance and operating costs) of specific projects. This means that a variety of drive options can be defined even before the design stage. Together with you, we then determine an optimal concept based on your needs.
Note.
- mtu Hybrid PowerPacks can be used in new rail vehicles or for repowering.
- It looks to me, that the total of 161 of Class 195, 196 and 197 trains, that will soon be all in service in the UK may well have been designed to be converted to hybrid power using mtu Hybrid PowerPacks.
- In Would You Buy A Battery Energy Storage System From Rolls-Royce?, I talk about how mtu EnergyPacks are also used for battery storage.
- In fact, mtu EnergyPacks could be the secret ingredient to both systems.
This looks like a typical Rolls-Royce product, that pushes the design to the full.
I will be very surprised if LNER’s new CAF tri-mode trains are not powered by mtu Hybrid PowerPacks.
I have a few thoughts.
CAF Are Going For A Proven Solution
CAF are going for a proven power solution, that they will also need for 161 trains in the UK.
Integration of systems like these can be difficult but CAF are using another company to combine diesel, electric and battery power in an efficient way.
I also feel that mtu Hybrid PowerPacks have a big future and Rolls Royce mtu will do what it takes to make sure they dominate the market.
Decarbonising The Trains
I suspect given Rolls-Royce’s philosophy, that the diesel engines will run on sustainable fuels from delivery.
But as the extract from the Modern Railways article says, the space used by diesel engines can be used for batteries.
Follow The Money
Consider.
- Porterbrook and Rolls-Royce are both based in Derby.
- Porterbrook are a rolling stock leasing company, who own a lot of rolling stock, that could be converted to hybrid trains, using mtu Hybrid PowerPacks.
- Porterbrook are financing LNER’s new CAF tri-mode trains.
I wouldn’t be surprised if Porterbrook and Rolls-Royce have done a lot of due diligence on these trains.
Other Train Operators Will Follow
LNER’s new CAF tri-mode trains may be a bespoke design for LNER, but other train operators will need a similar train.
- CrossCountry need a replacement low-carbon fleet.
- ScotRail need a replacement fleet for their Inter7City services.
- Great Western Railway need a replacement fleet for their GWR Castles.
- Grand Central need a replacement low-carbon fleet.
- TransPennine Express need new trains.
- Open Access Operator Grand Union Trains will need trains.
I think CAF are gong to be busy.
Conclusion
The more I read about Rolls-Royce and its engineering, the more I’m impressed.
First Tri-Mode Long Distance Trains For The East Coast Main Line
The title of this post, is the same as that of this press release from LNER.
This is the sub-heading.
London North Eastern Railway (LNER) is pleased to confirm that CAF has been named as the successful bidder to deliver a fleet of 10 new tri-mode trains for LNER. Porterbrook has been chosen as the financier of the new fleet. The trains will be able to operate in electric, battery or diesel mode.
These are the first two paragraphs.
Benefits of tri-mode trains range from a reduction in emissions, particulates, noise and vibration pollution, lower maintenance and operating costs and upgradeable technology, with an expected increase in range and performance as technology develops further. Battery power reduces the need to use diesel traction in areas where overhead powerlines are not available.
Complementing the modern Azuma fleet of 65 trains, the new ten-coach trains will help LNER achieve its vision of becoming the most loved, progressive and trusted train operator in the UK, delivering an exceptional service for the customers and communities served along its 956-mile network.
I have a few thoughts.
Will The Trains Have Rolls-Royce mtu Diesel Engines?
Consider.
- CAF’s Class 195, 196 and 197 Civity trains for the UK all have Rolls-Royce mtu diesel engines.
- Porterbrook are headquartered in Derby.
- Rolls-Royce are headquartered in Derby.
- In Rolls-Royce And Porterbrook Agreement Will Drive Rail Decarbonisation, I talked about how the two companies were planning to decarbonise trains using techniques like mtu Hybrid PowerPacks and hydrogen fuel cells.
I would think it very likely that the new trains will have Rolls-Royce mtu engines.
Will The Trains Have Rolls-Royce mtu Hybrid PowerPacks?
It was in 2018, that I first wrote about mtu Hybrid PowerPacks in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks.
- Examples of these power packs are now running in Germany, Ireland and the UK.
- The mtu Hybrid PowerPack how has its own web site.
- There is also this YouTube video.
- If CAF use off-the-shelf mtu Hybrid PowerPacks in their Civity trains, there is one big massive plus – They don’t have to develop the complicated control software to get a combination of diesel engines and batteries to perform as immaculately as Busby Berkeley’s dancers or a Brigade of Guards.
- The mtu Hybrid PowerPacks also have a big plus for operators – The batteries don’t need separate charging infrastructure.
- In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, I talk about how mtu engines can run on sustainable fuels, such as biodiesel or HVO.
I think it is extremely likely that CAF’s new trains for LNER will be powered by mtu Hybrid PowerPacks.
Class 800 And Class 397 Trains Compared
The Class 800 train is LNER’s workhorse to Scotland from London.
The Class 397 train used by TransPennine Express, is a 125 mph Civity train.
Differences include.
- The Class 800 train can run at 140 mph, where the signalling allows, but is the Class 397 train only capable of 125 mph?
- The Class 397 train accelerate at 0.92 m/s², whereas the Class 800 train can only manage 0.7 m/s².
- The Hitachi train has 14 % more seats, 36 First and 290 Standard as opposed to 22 First and 264 Standard in five-car trains.
I will add to this list.
Will The New Trains Be Capable Of 140 mph Running?
As the East Coast Main Line is being fully digitally signalled to allow 140 mph running of the numerous Hitachi expresses on the route, I wouldn’t be surprised to see, that the new CAF trains will be capable of 140 mph.
In this article on Modern Railways, which is entitled LNER Orders CAF Tri-mode Sets, this is said.
The new fleet will be equipped with CAF Signalling’s European Rail Traffic Management System digital signalling. This will align with the East Coast Digital Programme, which aims to introduce European Train Control System (ETCS) on the southern stretch of the East Coast main line from King’s Cross to Stoke Tunnel by 2029.
Later in the article this is said.
LNER has retained 12 ‘91s’ hauling eight rakes of Mk 4s, and the rollout of ETCS is another reason the operator has sought to order the replacement fleet. LNER’s passenger numbers have rebounded more quickly than other operators post-Covid, which has helped make the case for confirming the order.
This does seem sensible.
What Will Be The Range Of The CAF Trains Without Electrification?
The longest LNER route without electrification is the Northern section of the Inverness service between Inverness and Dunblane, which is 146.1 miles. There are also eight stops and some hills.
In Edinburgh to Inverness in the Cab of an HST, there’s a video of the route.
I’m sure that even, if they don’t normally run the new trains to Inverness, being able to do so, could be useful at some point.
It should be noted that the Guinness World Record for battery-electric trains is 139 miles, which is held by a Stadler Akku.
I am left with the conclusion that London and Inverness needs a tri-mode train or lots of electrification. Did this rule out Hitachi?
The Number Of Trains Ordered
The Modern Railways article says this about the number of trains.
The contract includes an eight-year maintenance services agreement with an option to extend; CAF says the order value, including maintenance, exceeds €500 million. When the tender was published the intention was to include an option for five additional sets; LNER confirmed to Modern Railways there is an option to purchase additional sets on top of the base order of 10.
Can we assume this means that other trains will be ordered, if the trains are a success?
Can These New CAF Trains Be Made Net Zero?
This is a paragraph, in the LNER press release.
This new fleet of trains will keep LNER on track to reduce its emissions by 67 per cent by 2035 and be net zero by 2045. LNER has already reduced carbon emissions by 50 per cent compared with 2018/19. Per mile, LNER trains produce 15 times less carbon emissions than a domestic flight.
As the new CAF trains will probably have a service life of at least forty years, there must be some way, that these new trains can be made net zero.
Consider.
- I am absolutely certain, that the new CAF trains will have Rolls-Royce mtu diesel engines.
- LNER’s existing Class 800 and 801 trains have Rolls-Royce mtu diesel engines.
Rolls-Royce mtu according to some of Rolls-Royce’s press releases appear to be developing net zero solutions based on hydrogen or net zero fuels.
This press release from Rolls-Royce is entitled Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen, suggests that Rolls-Royce mtu are working on a solution.
Routes They Will Serve
The Modern Railways article says this about the routes to be served.
Modern Railways understands the new fleet will be maintained at Neville Hill depot in Leeds and, like the ‘225’ sets, will be used predominantly on services between London and Yorkshire, although unlike the ‘225s’ the tri-modes, with their self-power capability, will be able to serve destinations away from the electrified network such as Harrogate and Hull.
Note.
- This surprised me, as I’d always expected the Yorkshire routes will be served by Hitachi battery-electric trains.
- But it does look that both Harrogate and Hull stations, have long enough platforms to hold a ten-car train.
- With their tri-mode technology, it also looks like the CAF trains won’t be needed to be charged before returning to London.
The last point would enable them to try out new routes.
These are distances from the electrification of the East Coast Main Line of the destinations that LNER served, where there is not full electrification.
- Aberdeen via Ladybank – 91.4 miles
- Carlisle via Skipton – 86.8 miles
- Cleethorpes via Newark and Lincoln – 63.9 miles
- Harrogate via Leeds – 18.3 miles
- Huddersfield via Leeds – 17.2 miles
- Hull via Temple Hirst junction – 36.1 miles
- Inverness via Dunblane – 146.1 miles
- Lincoln via Newark – 16.7 miles
- Middlesbrough via Northallerton – 22.2 miles
- Scarborough via York – 42.1 miles
- Sunderland via Northallerton – 47.4 miles
Note.
- The first place after the ‘via’ is where the electrification ends.
- Carlisle could be a possibility during High Speed Two upgrading of the West Coast Main Line or for an enthusiasts’ special or tourist train.
- Cleethorpes is a possible new service for LNER. I wrote about this in LNER To Serve Cleethorpes.
- Scarborough must be a possible new service for LNER.
- All stations can take ten-car trains, with the possible exception of Middlesbrough, which is currently being upgraded.
- Huddersfield and Leeds is being electrified under the TransPennine Upgrade.
This would appear to show that LNER need enough bi-mode or tri-mode trains to run services to Aberdeen, Cleethorpes, Harrogate, Hull, Inverness, Lincoln, Middlesbrough and Sunderland.
But.
- It would appear that the initial batch of trains, will not be serving the North of Scotland.
- Aberdeen and Inverness could be served, when there is enough electrification at the Southern end.
I am also fairly sure, that no significant infrastructure is required.
Do Hitachi Have A Problem?
I am starting to wonder, if Hitachi are having trouble with the designing and building of their battery packs.
- It’s not like Hitachi to allow someone to run off with a €500 million contract from under their nose.
- Are they short of capacity to build the trains at Newton Aycliffe?
But then they’re probably up to their elbows in work on the High Speed Two Classic-Compatible trains.
Are There Any Other Routes, Where The New CAF Trains Could Be Employed?
The trains would certainly be suitable for these routes.
- Chiltern – InterCity services.
- CrossCountry Trains – Fleet replacement
- Grand Central Trains – Fleet replacement
- Grand Union Trains – For Carmarthen and Stirling open access services.
- Great Western Railway – Replacing Castles in the South West.
- ScotRail – Replacing Inter7City trains.
- South Western Railway – Basingstoke and Exeter St. Davids and other routes.
Note.
- CAF could sell a lot of trains.
- I estimate that fleet replacement for Grand Central Trans would cost around €350 million
- The specification would vary according to the route.
Could CAF have got the LNER order, because they have the capacity in the Newport factory?
Conclusion
It looks like CAF have done a good job in designing the trains.
I’m also fairly sure that CAF are using Rolls-Royce mtu PowerPacks.
‘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.
Thales Supports Rollout Of UK Digital Railway Programme
The title of this post, is the same as that of this press release from Porterbrook.
The press release starts with these bullet points.
- Thales wins the fitment and supply of European Train Control System (ETCS) onboard units for Class 43 high-speed train retrofit.
- Implementation will benefit passengers and freight operators by delivering additional capacity, improving performance, enhancing safety and reducing the costs of operating the national railway.
Which is followed by this explanation.
As a key player in delivering this digital transformation, Thales has today been awarded the contract for the Class 43 First in Class (FiC) design and fitment project that will use Network Rail’s new measurement train power cars in the Infrastructure Measurement fleet. The FiC project will culminate in a Type approval from the Office of Road and Rail to enable subsequent Class 43 ETCS fleet fitments.
The new Thales onboard system will be integrated as part of the Digital Railway train control system, and will enable rolling stock to operate on ETCS-equipped infrastructure. The onboard equipment is an evolution of Thales’s level 1 ETCS system that has been successfully deployed worldwide.
This could be a smart move.
- Type Approval will mean that the Class 43 power cars of ScotRail’s Inter7Cities, Great Western Railway’s Castles and those of other operators can be retrofitted.
- Will the New Measurement Train also be used to test the digital signalling, as it covers all the tracks in Great Britain in a four-weekly cycle?
- Fitting of these iconic 1970’s designed power cars with the latest modern signalling could be a design exercise, that helps in the fitting of ETCS to other older and unusual locomotives.
I still think, that because of the iconic nature of the InterCity125, that we may see a conversion of Class 43 power cars to more sustainable operation.
- All power cars now have modern MTU diesel engines, which probably could be fuelled by hydrogen.
- The simplest way would be to run them on HVO, as I wrote about in Powered By HVO.
- Some operations like the short format trains in Scotland and South-West England might be more suitable for battery-electric operation.
- Given that there are 167 in operation or in store, it would be a good-sized order for the company converting the power cars.
I also believe that zero-carbon InterCity 125s could be an unusual tourist attraction.
Conclusion
The fitting of digital signalling to Class 43 power cars is a good move, but is it the start of a wider plan to bring these iconic trains up to modern standards.
Union Demands Withdrawal Of All HSTs After Carmont Report
The title of this post, is the same as that of this article on Railnews.
This is the first paragraph.
The TSSA union says it has written to the regulator demanding the immediate withdrawal of all surving HSTs, after new revelations in the Carmont derailment. report.
Manuel Cortes of the TSSA feels that the corrosion problem found in the train that crashed at Carmont, may be present in other trains.
He finishes with this this statement.
Frankly, it’s time to ban the HSTs. They were great in their day, but that day is nearly 50 years ago now and they simply aren’t up to modern safety standards.
I must admit, that I tend to agree with him, on this last point.
Scotrail have the following fleet of Inter7City trains.
- There are 52 Class 43 power cars and 120 Mark 3 coaches, which are arranged as nine four-car and seventeen five-car trains.
- The trains have sliding passenger doors.
- The trains meet all the regulations for Persons of Reduced Mobility.
- The trains have wi-fi and power points.
- They seem to run at up to 100 mph, as against the 125 mph for InterCity 125‘s in the past.
- The power cars have generally been reengined with modern MTU 16V4000 R41R diesel engines.
But they are now on average over forty years old.
In Battery And Hydrogen Trains For ScotRail ‘Could Make Scotland A Global Leader’ In Zero-Emission Transport, which is based on an article in the Scotsman with the same title, I said this.
Other points from the article.
- Talgo appear to have passed the story to Scotland on Sunday.
- Three routes are mentioned; Borders Railway, Fife Circle and Glasgow-East Kilbride.
- The new trains could help phase out diesel trains by 2035, which is Scottish Government policy.
- The Inter7City trains might be replaced by 2030.
- Talgo hopes to win an order for its factory in Fife.
Talgo’s Managing Director is quoted as saying, they are starting testing of a hydrogen and electric train with a range of 311 miles.
Consider.
- I wrote about this train in Talgo To Begin Fuel Cell Loco Trials.
- Talgo’s hydrogen and electric train would be ideal for Scotland’s railways of which only forty percent are electrified.
- A four or five-car high specification hydrogen and electric train would be ideal for the Inter7City routes, if it were built specifically for the routes.
- The range would cover all of Scotland.
- Hydrogen hubs are being planned all over Scotland.
- Scotland have 26 Inter7City trainsets.
This could be a rather nice order to fund the factory and test all the trains close to the factory.
- There could be as many as fifty trains.
- They would probably have an operating speed of 100 mph on electricity.
- Would the speed on hydrogen be 100 mph or perhaps a bit less?
- They would be able to use 25 KVAC overhead electrification, where it exists.
- They could have a length of three, four or five cars.
I wouldn’t be surprised to see three or four car trains for the suburban trains and four or five car trains for the Inter7City replacements.
Battery And Hydrogen Trains For ScotRail ‘Could Make Scotland A Global Leader’ In Zero-Emission Transport
The title of this post is the same as that of this article in the Scotsman.
This is the first paragraph.
New fleets of cutting-edge trains expected to include battery and hydrogen power are to be ordered for ScotRail which the rail industry believes will put Scotland at the forefront of zero-emission transport.

Is there a better place to show off your new train to a prospective buyer than the Highlands of Scotland?
In A Class 319 Train, But Not As We Know It!, I told this tale.
I am reminded of a tale, that I heard from a former GEC manager.
He was involved in selling one of GEC’s Air Traffic Control radars to a Middle Eastern country.
The only working installation of the radar was at Prestwick in Scotland, so he arranged that the dignitaries and the sales team would be flown to Prestwick in GEC’s HS 125 business jet.
As they disembarked at Prestwick and walked to the terminal, the pilot called the GEC Manager over.
The pilot told him “The Scottish Highlands at this time of the year, are one of the most beautiful places in the world! Would you and your guests like a low-level tour on the way back? I can arrange it, if you say so!”
Despite knowing GEC’s draconian attitude to cost control he said yes.
The sale was clinched!
I’m sure that Talgo will exploit the scenery and the local produce.
Talgo’s Hydrogen Trains
This page on the Talgo web site, is entitled Talgo’s Hydrogen Train Will Be Ready In 2023.
This paragraph gives an overview of Talgo’s hydrogen power system.
This system is configured as a modular solution that can be installed on all types of trains, as well as in upgrades from diesel to hydrogen. However, it has been specifically designed for the Vittal platform for Commuter and Regional trains, which Talgo has presented in the bidding process for various tenders in Spain and other countries.
And these two paragraphs describe Talgo’s hydrogen trains in more detail.
This innovative system uses hydrogen batteries that provide the energy for the train’s electric motors. It is powered by renewable energy sources, such as solar photovoltaic or wind, which produce hydrogen that is stored and then used to power fuel cell-based propulsion systems, such as the one designed by Talgo. The system is complemented by batteries that increase the speed of the train when it starts, taking advantage of the braking system to recharge it.
Unlike the extended battery systems in the automotive industry, hydrogen (H2) technology is the logical answer to the needs of heavy transport and, in particular, of those railway lines that do not have catenary electrification systems, and which today depend on trains powered by diesel engines. The hydrogen system designed by Talgo enables conventional network lines to be “electrified” without the need for costly and lengthy adaptation operations, and without the use of fossil fuels.
What do they mean by hydrogen batteries? Looking at the German and the Spanish on the page, I think Talgo means hydrogen fuel cells.
The Rebuilding Of Ukraine
It should be noted that Talgo have sold trains in the past to Russia, which has a gauge of 1.520 metres, which lies between Iberian gauge of 1.668 metres and our standard gauge of 1.435 metres.
- Talgo have also sold trains to Germany, who use standard gauge.
- Talgo have built Strizh trains for Russia, that are both standard gauge and Russian gauge for running between Berlin and Moscow.
- According to the BBC and The Times, Ukraine’s railways have been an important lifeline during the Russian invasion, but pictures show they are in need of modernisation and more electrification.
- The Strizh trains or a development would surely be ideal for running between Kviv and Berlin, Budapest, Prague and Warsaw.
- There would also appear to be a need for a hydrogen and electric regional train to reconnect the country back together.
- Other countries using Russian gauge include Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Armenia, Azerbaijan, Georgia, Belarus, Moldova, Estonia, Latvia, Lithuania, and Finland.
So are Talgo positioning themselves to take part in the modernisation of Ukraine’s railways, once the war is over?
- Development and testing is done in Spain and Scotland.
- Manufacturing could be done in Spain and Scotland.
- Delivery from Scotland could either be by ship or if they were dual-gauge trains, they could be hauled through the Channel Tunnel and then through Germany and Poland.
As Talgo has the technology, I can certainly see them exploiting the Russian gauge market once Vlad the Mad has gone.
ScotRail Offers 1st Class For £3 As Luxury Travel Reintroduced
The title of this post, is the same as that of this article on Rail Advent.
To encourage passengers back after the pandemic, Scotrail have introduced a three pound onboard upgrade to First Class on services on Inter7City and Class 385 train services.
This sounds like a good idea!
Through Settle And Carlisle Service Under Consideration
The title of this post, is the same as that of an article in the June 2021 Edition of Modern Railways.
This is the first paragraph.
Plans for a new Leeds to Glasgow through service via the Settle and Carlisle line are being developed, with CrossCountry and the Department for Transport starting to look at the possible scheme.
It sounds like a sensible idea to me.
The article also suggests the following.
- CrossCountry is a possible operator.
- CrossCountry are keen to improve services between Leeds and Glasgow
- The trains could be InterCity 125s, freed up, by a the arrival of Class 221 trains from Avanti West Coast, when they receive their new Class 805 trains.
- Maintenance of the trains wouldn’t be a problem, as this could be done at Neville Hill in Leeds or Craigentinny in Edinburgh.
- Services could start in December 2023.
I have a few thoughts of my own!
The Route
The route between Leeds and Carlisle is obvious, but there are two routes between Carlisle and Glasgow.
Trains would probably choose a route and call at stations to maximise passenger numbers.
These stations are on the various routes.
- Settle and Carlisle – Shipley, Bingley, Keighley, Skipton, Gargrave, Hellifield, Long Preston, Settle, Horton in Ribblesdale, Ribblehead, Dent, Garsdale, Kirkby Stephen, Appleby, Langwathby, Lazonby & Kirkoswald and Armathwaite
- Glasgow South Western – Dunlop, Stewarton, Kilmaurs, Kilmarnock, Auchinleck, New Cumnock, Kirkconnel, Sanquhar, Dumfries, Annan and Gretna Green
- West Coast Main – Motherwell, Carstairs and Lockerbie
There are certainly a lot of possibilities.
Upgrading The InterCity 125 Trains
CrossCountry appear to have enough InterCity 125 trains to muster five in a two Class 43 power car and seven Mark 3 coach formation.
They may not be fully in-line with the latest regulations and there may be a need for a certain degree of refurbishment.
These pictures show some details of a refurbished Great Western Railway Castle, which has been fitted with sliding doors.
Will The InterCity 125 Trains Be Shortened?
Scotrail’s Inter7City trains and Great Western Railway’s Castle trains have all been shortened to four or five coaches.
This picture shows a pair of Castles.
Journey Times, Timetable And Frequency
The current journey time between Leeds and Glasgow Central stations via the East Coast Main Line is four hours and eight minutes with nine stops.
The Modern Railways article says this about the current service.
The new service would be targeted at business and leisure travellers, with through journey times competitive with road and faster than the current direct CrossCountry Leeds to Glasgow services via the East Coast main line.
I would expect that CrossCountry are looking for a time of around four hours including the turn round.
- Stops could be removed to achieve the timing.
- The trains could run at 125 mph on the West Coast Main Line.
This could enable a train to have the following diagram.
- 0800 – Depart Leeds
- 1200 – Depart Glasgow Central
- 1600 – Depart Leeds
- 2000 – Depart Glasgow Central
- Before 2400 – Arrive Leeds
Note.
- A second train could start in Glasgow and perform the mirrored timetable.
- Timings would probably be ideal for train catering.
- Trains would leave both termini at 0800, 1200, 1600 and 2000.
- The timetable would need just two trains.
I also think, if a second pair of trains were to be worked into the timetable, there could be one train every two hours on the route, if the demand was there.
I certainly believe there could be a timetable, that would meet the objectives of attracting business and leisure passengers away from the roads.
Tourism And Leisure Potential
The Settle and Carlisle Line is known as one of the most scenic railway lines in England, if not the whole of the UK.
There are important tourist sites all along the route between Leeds and Glasgow
- Leeds – The station is well-connected in the City Centre.
- Saltaire – For the World Heritage Site and Salt’s Mill
- Keighley – For the Keighley and Worth Heritage Railway
- Settle – The town of Settle is worth a visit.
- Ribblehead – For the famous Ribblehead Viaduct
- Appleby – For the Horse Fair.
- Carlisle – The station is well-connected in the City Centre.
- Glasgow – Glasgow Central station is well-connected in the City Centre.
Many of the stations are used by walkers and others interested in country pursuits.
I believe that it is a route that needs a quality rail service.
Travel Between London and Towns Along The Settle And Carlisle Line
In Thoughts On Digital Signalling On The East Coast Main Line, I said this.
I think it is highly likely that in the future, there will be at least one train per hour (tph) between London Kings Cross and Leeds, that does the trip in two hours.
It may seem fast compared to today, but I do believe it is possible.
With a timely connection at Leeds station, will this encourage passengers to places along the Settle and Carlisle line to use the train?
What About the Carbon Emissions?
The one problem with using InterCity 125 trains on this route, is that they are diesel-powered, using a pair of Class 43 locomotives.
But then there are over a hundred of these diesel-electric locomotives in service, nearly all of which are now powered by modern MTU diesel engines, which were fitted in the first decade of this century.
Consider.
- The locomotives and the coaches they haul have an iconic status.
- Great Western Railway and Scotrail have recently developed shorter versions of the trains for important routes.
- There are over a hundred of the locomotives in service.
- Companies like ULEMCo are developing technology to create diesel-powered vehicles that can run on diesel or hydrogen.
- There is plenty of space in the back of the locomotives for extra equipment.
- MTU have a very large number of diesel engines in service. It must be in the company’s interest to find an easy way to cut carbon emissions.
- I believe that the modern MTU diesel engines could run on biodiesel to reduce their carbon footprint.
And we shouldn’t forget JCB’s technology, which I wrote about in JCB Finds Cheap Way To Run Digger Using Hydrogen.
If they could develop a 2 MW hydrogen engine, it could be a shoe-in.
I believe that for these and other reasons, a solution will be found to reduce the carbon emissions of these locomotives to acceptable levels.
Conclusion
In this quick look, it appears to me that a Glasgow and Leeds service using InterCity 125 trains could be a very good idea.
