Centrica Buys Severn Gas Power Station In South Wales
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
The owner of British Gas says the plant, acquired from the troubled Calon Energy for £370 million, will help secure supplies during the green transition
These three introductory paragraphs add more details to the story.
The owner of British Gas has acquired the troubled Severn gas power station in south Wales for £370 million after issuing a less than positive future profit guidance.
The combined-cycle gas turbine plant was owned by Calon Energy, which had gone into administration shortly after the start of the pandemic in 2020 when the power station was, for a while, mothballed.
Centrica said it acquired the plant to shore up its energy generation resources and secure electricity supplies during the UK’s green transition.
I think there a lot more to this story, than initially meets the eye.
The Location
The Google Map shows the location of the Severn Power station on the River Usk, to the South of Newport in South Wales.
Note.
- Severn power station is indicated by the red arrow in the South-West of the map.
- The River Usk enters the sea to the West of the site.
- The RSPB Newport Wetlandsare South of the site.
- The long rectangle in the middle of the map is the former Llanwern steelworks, which is now a CAF train factory.
- Newport is also a major station on the main line between London Paddington and Cardiff.
This second Google Map shows the power station site at a larger scale.
I wouldn’t be surprised, that Centrica could fit other equipment on and around the power station site.
- Centrica and/or National Grid might want to put an interconnector across the Severn Estuary.
- There might be a need to connect to wind farms in the Severn Estuary.
- Centrica are building a bunkering facility for ships running on low carbon fuels at Grain LNG Terminal. Will they build one here?
- Centrica could build a HiiROC electrolyser to create hydrogen for difficult to decarbonise industries and bunkering ships.
The site has a lot of potential.
Could A Feeder Network Of Local Trains Be Developed For HS2 At Lancaster Station?
Lancaster station is one of the less important stations that will be served by High Speed Two.
I visited in May 2025 and afterwards wrote Lancaster Station – 23rd May 2025.
This OpenRailwayMap shows the railway network around Lancaster.
Note.
- The red track on the East side of the map is the electrified West Coast Main Line.
- The location of Lancaster station is indicated by a blue arrow.
- Morecambe, where the Eden Project North is being developed and the important port of Heysham are on the coast to the West of Lancaster.
- Oxenholme station is towards the North-East corner of the map, on the main line.
- The Windermere branch connects to the main line at Oxenholme station.
- HS2 will use the West Coast Main Line and call at Lancaster and Oxenholme.
North of Oxenholme, HS2 calls at Penrith and Carlisle, before going on to Glasgow and Scotland.
West of the main line, the map is dominated by the waters of Morecambe Bay, which in recent decades has produced a lot of our gas, but is now transitioning to an area, that will produce a few gigawatts of wind power.
North of Morecambe Bay, there is the Lake District, with the shipbuilding at Barrow and the nuclear waste processing at Sellafield on the coast.
It is an important area of England, where there is a lot going on!
Tying it all together is the yellow ribbon of the Cumbrian Coast Line, which connects Carnforth and Carlisle on an hourly basis.
- The service calls at Grange-over-Sands, Barrow-in-Furness, Millom, Ravenglass, Drigg, Seascale, Sellafield, St Bees, Whitehaven, Workington, Maryport, Aspatria, Wigton and other places.
- Four services a day link Carlisle and Lancaster stations.
- Carlisle and Lancaster stations are 120.5 miles apart via the coast and according to Google AI, the journey takes between three and three-and-a-half hours.
- In From Barrow-in-Furness To Ravenglass, From Ravenglass to Sellafield and From Sellafield To Carlisle, there are some images, that give a flavour of the route.
This is a route, that is worth decarbonising.
Consider.
- There is a couple of gigawatt of wind power in the bay to charge any batteries with green electricity or make green hydrogen.
- There is a project called BARROW GREEN HYDROGEN, which is located in Barrow-in-Furness.
- Both hydrogen and battery-powered trains could handle the hundred and twenty miles of the Cumbrian Coast Line.
- A zero-carbon train running silently round the Lake District could be a tourist attraction in its own right.
- Hydrogen-powered buses could provide the local transport.
Given the scenery and the closeness to the Lake District and High Speed Two, I suspect that major train manufacturers like Alstom, CAF and Siemens will be keen to bid.
How To Take A Ride On A New Docklands Light Railway Train
This article on the BBC is entitled After Delays, New Trains Finally Arrive On The DLR.
This is the sub-heading.
The first of 54 new trains for the Docklands Light Railway (DLR) is now in service, featuring “the latest technology”, according to Transport for London (TfL)
These two paragraphs add more details.
The new carriages are air-conditioned, have mobile device charging points and dedicated spaces for wheelchair users.
They will replace the oldest trains in the DLR fleet, some of which have been in service for more than three decades, with “modern, high-capacity trains designed to meet the needs of a growing city”, said TfL.
I travelled to West Ham station this morning and took these pictures on a journey to Woolwich Arsenal.
Note.
- The Docklands Light Railway and the Jubilee Line are on the same level and connected by the bridge in West Ham station.
- The old DLR trains have red bodywork and the new trains have light blue bodywork.
- The first train through was a test train.
- The last row of pictures show the comparative length of the two trains at Woolwich Arsenal station.
These are some more detailed thoughts.
The Length Of The New Trains
The original cars are 28 metres long.
- Running as a 2-car train, the trains are 56 metres long.
- Running as a 3-car train, the trains are 84 metres long.
- The new 5-car trains are 86.7 metres long.
I asked Google AI how many seats were in a DLR train and received this answer.
A DLR (Docklands Light Railway) train’s seat count varies by the specific rolling stock, but newer trains have a higher capacity; for example, the new B23 rolling stock is a 5-coach unit replacing older, coupled 3-car trains and offers a total capacity of 790 passengers, with 156 seats. Older trains typically consist of two cars and have 70 seats per car for a total of 140 seats.
Newer B23 Rolling Stock:
Each 5-coach train has 156 seats.
It can carry a total of 790 passengers.
Older Trains:
These trains generally consist of two cars coupled together.
Each car has 70 seats, making for a total of 140 seats in a typical two-car train.
Older, single-unit trains may have had fewer seats, as a current 3-car train had about 680 passengers in total capacity.
West Ham Was A Good Place To Start A First Ride
Consider.
- At the present time, there aren’t many trains running on the DLR.
- There may only be a couple of trains running between Stratford International and Woolwich Arsenal.
- West Ham is an island platform, so the train goes by on both sides, which also makes it easy to get on a single train.
- West Ham is a well-connected station.
I did have to wait about thirty minutes for the train to arrive.
Battery-Powered Train Breaks Distance Record
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A battery-powered train has broken the world record for the longest railway journey on a single charge.
These three introductory paragraphs add more details.
The Great Western Railway (GWR) train – a specially adapted former District Line train – travelled overnight along a 200-mile (322km) route from Reading and back again, via London Paddington and Oxford.
It reached 140 miles (225km), breaking the record on Brunel’s Maidenhead Bridge at about 04:00 BST.
The previous record of 139 miles (224km) was set by German train company Stadler Deutschland in Berlin on 10 December 2021.
This was an impressive demonstration of the capabilities of battery-electric trains.
Will This Record Be Beaten?
200 miles is impressive, but there was also this paragraph in the article.
At the end of the journey GWR said there was a remaining battery charge of 22% which it estimated would have allowed the train to travel about a further 58 miles (93km).
So it looks like 258 miles should be possible.
Four other companies are also developing battery-electric trains.
- Alstom at Derby
- CAF at Newport
- Hitachi at Newton Aycliffe
- Siemens at Goole
- Stadler in Switzerland.
Note.
- All except Stadler have UK factories.
- Siemens and Stadler have delivered trains in Germany.
- This page on the Hitachi Rail web site is entitled Intercity Battery Trains.
- This page on the Hitachi Rail web site is entitled Hitachi Wins New UK Contract To Build Intercity Battery Trains. The customer is Grand Central Trains.
- Hitachi have been running a prototype for some months, in the UK.
The competition is hotting up and the record will certainly be soundly beaten.
London Underground’s New Piccadilly Line Trains Delayed Until 2026
The title of this post, is the same as that of this article on Railway Gazette.
These are the first two paragraphs.
The new air-conditioned trains which Siemens Mobility is supplying for London Underground’s Piccadilly Line are now expected to enter service from the second half of 2026, Transport for London has confirmed.
When the order was signed in November 2018 it was envisaged that the trains would enter service from 2024.
The article also says this about the new CAF trains for the Docklands Light Railway.
The Docklands Light Railway is to implement ‘short-term timetable changes’ on less busy routes from July 21. The reduction in services aims to ensure that reliability can be maintained pending the delayed introduction of new CAF trainsets, which was originally planned for 2023 but is now expected later this year. TfL said the age of the existing trains meant some needed to be retired this summer.
It looks like has two sets of new trains, both being delivered two years late; one being German and the other Spanish.
The only factors I can think both trains being late would be.
- Bad management of the contracts by Transport for London.
- Bad documentation of the Piccadilly Line and the Docklands Light Railway, when they were built.
- Bad project management generally throughout Europe.
- All politicians will be blaming someone else.
Take your pick!
Support For Edinburgh Tram-Train Scheme
The title of this post, is the title of a third-of-a-page article in the June 2025 Edition of Modern Railways.
This is the first paragraph.
Final-Year civil engineering undergraduates at Heriot-Watt University’s Edinburgh campus have received warm support for a study in which they recommend reopening the city’s 7.5 mile South Suburban Railway, used for freight and diversions since 1962, using tram-trains.
It looks like they would start in the West at say Edinburgh Gateway or the Airport and would then turn South at Murrayfield to join the South Suburban Railway at Gorgie.
This OpenRailwayMap shows the tracks to the South of Murrayfield stadium.
Note.
- The more Westerly-oriented orange tracks lead to Glasgow.
- The orange tracks running South-Westerly are the tracks to Carstairs.
- The yellow tracks are the South Suburban Railway.
- Tram-trains could then go all the way to Brunstane on the Borders Railway.
- The blue arrow indicates the tram-stop for Murrayfield.
- I would assume that the connection to the South Suburban Railway, is to the East of this stop.
- Gorgie East, Craiglockhart and Morningside Road were stations on the South Suburban Railway.
This map shows where the South Suburban and Borders Railways meet in a large triangular junction.
Note.
- Newcraighall station on the Borders Railway is in the South-East corner of the map.
- Brunstane station is to its North-West almost halfway up the map.
- The two stations are the North and South points of the triangular junction, where the South Suburban and Borders Railways meet.
- The South Suburban can be seen going West towards Gorgie and Murrayfield.
- Edinburgh’s beach at Portobello is in the North-East corner of the map.
- Between Murrayfield and Brunstane, there would be an appropriate number of tram stops and a tram-train every fifteen minutes.
Optionally, the route can be extended to Leith on a mothballed freight line.
This OpenRailwayMap shows the railways and tramways of Edinburgh between Brunstane, Edinburgh Waverley and Leith.
Note.
- The orange track running across the bottom of the map is the East Coast Main Line into Edinburgh Waverley station, which is clearly marked.
- The pink track is the Edinburgh tram to Newhaven.
- Brunstane station is in the South-East corner of the map.
- The site of the former Portobello station is marked by the blue arrow.
- The yellow track from Portolbello up the coast is a mothballed freight line to Leith Docks.
The proposal suggests that the tram-train route finishes at Leith Docks. One of the reasons, is that this part of Edinburgh, is not well served by public transport.
I have some extra thoughts.
Changing Between Borders Railway and the Tram-Train At Brunstane Station
Brunstane station, is a two-track station, with only one platform, so there may need to be track modifications.
Do Edinburgh’s Urbos Trams Have A Tram-Train Variant?
They do!
Do Edinburgh’s Urbos Trams Have A Battery Variant?
Battery tram-trains charged at either end of the route will be needed.
A battery-electric Urbos 3 tram, can be seen running through the City of Birmingham in England.
Conclusion
The proposal looks feasible to me. But the devil will be in the detail.
Mayors Head To Parliament With Plan For Northern Arc To Deliver Green Growth
The title of this post, is the same as that of this news item from Liverpool City Region.
These four bullet points act as sub-headings.
- Steve Rotheram and Andy Burnham take case for backing Northern Arc to Treasury – as new data shows North can drive green growth and unlock £90bn for UK economy
- Liverpool City Region and Greater Manchester Mayors will meet with ministers and MPs today, and Andy Burnham will give evidence at Business and Trade Select Committee on the UK’s industrial strategy
- Economic analysis shows that investing in transport infrastructure and a pipeline of projects across the North would benefit the whole UK economy, improving living standards and closing the North-South productivity gap
- Mayors will also address Innovation Zero World Congress in London, showing how city-regions can create high quality jobs by pioneering low-carbon innovation
These two paragraphs add a bit more detail.
The right investment would create a growth corridor, stretching from the Mersey to the Pennines and connecting into West and South Yorkshire, underpinned by transport networks that would include a new railway linking Liverpool and Manchester.
The Northern Arc area spans regions with close economic ties to Lancashire, North Wales, Hull and the North East. With international connections through the Port of Liverpool and Manchester Airport, it’s well positioned for global trade.
If I have a problem with the mayors’ thoughts, the plan outlined in the news item is rather Liverpool/Manchester-based with Hull being the only city outside that area getting a mention. Do Blackburn, Blackpool, Bradford, Burnley, Doncaster, Huddersfield, Leeds, Preston, Rotherham, Scunthorpe, Stockport, Wigan and York exist?
For instance you would expert a report from Liverpool and Manchester’s Mayors to call for a new railway between their two cities. And of course they do!
The current TransPennine Lines has two main routes across the Pennines between East and West.
If ever there was a rail route, designed by Topsy, it is the North TransPennine Route.
- There are six separate services, if you ignore Newcastle and Edinburgh Waverley, which is a shuttle to fill a gap in rail services.
- In the West trains terminate at Huddersfield, Liverpool Lime Street, Manchester Airport, Manchester Piccadilly and Manchester Victoria
- In the East trains terminate at Edinburgh Waverley, Hull, Leeds, Newcastle, Redcar Central, Scarborough and York.
- Terminals like Huddersfield, Hull, Liverpool Lime Street, Newcastle and York are some of the best terminal stations in the UK, but others are very second rate.
I suspect, this North TransPennine Route structure brought about the demise of TransPennine Express.
The South TransPennine Route on the other hand, although it was built by several different railway companies, they were all intent on the same thing. An East-West route across the Pennines through Doncaster, Manchester and Sheffield.
- The Western terminal is Liverpool Lime Street, which in my view is the finest grand terminus in the UK, in terms of architecture, onward connections and operation. It is also the oldest still-operating grand terminus mainline station in the world, in that it dates from 1836.
- The Eastern terminal is Cleethorpes, which is an efficient four-platform recently-refurbished station, that is within a hundred metres of some of the best gluten-free fish and chips, I’ve ever tasted on the pier.
- Intermediate stations include Liverpool South Parkway, Warrington Central, Birchwood, Irlam, Urmston, Manchester Oxford Road, Manchester Piccadilly, Stockport, Sheffield, Meadowhall, Doncaster, Scunthorpe, Barnetby, Habrough and Grimsby Town.
- Liverpool South Parkway has a bus connection to Liverpool Airport
- Liverpool Lime Street, Manchester Oxford Road, Manchester Piccadilly, Stockport, Sheffield and Doncaster are stations with comprehensive onward connections.
- The route is electrified between Liverpool Lime Street and Manchester Piccadilly and at Doncaster.Liverpool Lime Street and Cleethorpes is 148.2 miles
- Hazel Grove and Doncaster is without electrification and is 52.3 miles long.
- Cleethorpes and Doncaster is without electrification and is 52.1 miles long.
- I believe that Hitachi, Siemens and Stadler could supply battery-electric trains, that would be able to work the route, with the addition of a short length of overhead wires at Cleethorpes, so that trains could return to Doncaster.
- Trains go straight through all the intermediate stations, so there are no time-wasting reverses.
- Journey time is just over three and a half hours.
I believe that a mouse-quiet battery-electric train would pack in the punters, if only for the novelty.
But.
A battery-electric train would probably knock perhaps thirty minutes off the journey.
The timetable would be an hourly train at all stations.
The service would pass the mother’s birthday test, in that you could easily visit any station from any other and buy your mother lunch before returning on a convenient train.
There are connections to and from London at Liverpool Lime Street, Manchester Piccadilly, Stockport, Sheffield and Doncaster.
It could be a very useful East-West train service.
Extending The Sheffield Tram-Train To Adwick
I must admit, I very much like the Class 399 tram-trains in Sheffield and their German cousins in Karlsruhe.
I am not alone, as talking to an experienced Sheffield tram driver, he said that the extra power of the Class 399 tram-trains have over the Supertrams, mean they handle Sheffield’s hills with ease, when the tram-trains are full.
They have a top speed of 62 mph compared to a British Rail Class 150 train being able to manage 75 mph.
Passenger capacity of the two trains is probably about the same.
The Current Tram-Train Service
The service has the following characteristics.
- This runs between Sheffield Cathedral and Rotherham Parkgate via Meadowhall South and Rotherham Central stations.
- Services run every thirty minutes.
- I have heard rumours that an extra stop is going to be be added at Magna Science Adventure Centre.
London Overground and local rail services in Birmingham, Liverpool, Manchester and other cities in the UK, seem to run at a frequency of four trains per hour (tph).
The Current Northern Rail Service Between Sheffield And Adwick Via Doncaster
The service has the following characteristics.
- This runs between Sheffield and Aswick stations via Meadowhall, Rotherham Central, Swinton, Mexborough, Conisbrough, Doncaster and Bentley stations.
- Services run every hour.
- The service passes Rotherham Parkway Shopping Centre, but doesn’t stop.
Is there a need for this Northern Rail service to stop at Rotherham Parkway Shopping Centre?
The Current Electrification Between Sheffield And Rotherham
This OpenRailwayMap shows the electrified lines between Sheffield and Rotherham Parkway.
Note.
- Mauve tracks are electrified with 750 VDC overhead wires, so they can power Sheffield’s trams and tram-trains directly.
- Black tracks are not electrified.
- Meadowhall and its rail and tram interchange is in the South-West corner of the map.
- Note how mauve lines indicate the electrified tram tracks, that curve round the Meadowhall Shopping Centre.
- The blue arrow in the North-East corner indicates Rotherham Parkgate tram stop.
- The mauve line diagonally across the map, indicates the current electrification between Meadowhall South and Rotherham Parkgate tram stops.
- Magna Science Adventure Centre, is just to the South of the electrified Sheffield-Rotherham tram-line.
This second OpenRailwayMap shows the rail and tram lines between Sheffield and Rotherham in more detail.
Note.
- Track colours are as in the first map.
- The blue arrow in the North-East corner of the map indicates Holmes junction and is the route that Northern Rail’s current Sheffield and Adwick service takes.
- Sheffield and Rotherham Central stations are 6.1 miles apart.
- Sheffield and Adwick stations are 22.7 miles apart, but the Northern four miles between Doncaster and Adwick are electrified with 25 KVAC overhead wires.
This would indicate that a tram-train with a range of about twenty miles on battery power would be able to handle the route, if it could charge its batteries on the electrified lines.
Terminating a Sheffield And Adwick Service In Sheffield
This OpenRailwayMap shows the rail and tram lines in and through Sheffield station.
Note.
- Rail lines are in orange.
- Tram lines are in mauve.
- Platform numbers in Sheffield station are shown as blue dots. Click on the map to show it on a larger scale.
- Sheffield Cathedral tram stop is in the North-West corner of the map.
- The triangular junction in the North-East corner of the map, allows trams to use all the main tram lines that go in three directions. A touch of genius as it gives a lot of flexibility, when adding extra services.
Currently, termination of the services from Rotherham and Doncaster is as follows.
- The tram-train terminates at the Sheffield Cathedral tram stop with a frequency of two tph.
- The train terminates in Platform 3 in Sheffield station with an hourly frequency.
- As typically a terminal platform can handle 4 tph, I don’t see why a second Sheffield and Adwick service can’t be running every hour into Sheffield station.
A short length of overhead electrification would need to be added on Platform 3 to recharge any tram-trains terminating in the platform.
It could also become a tram and run to any of the other destinations served from the triangular junction; Halfway, Herdings Park or Malin Bridge. This would allow batteries to be charged as the tram-trains ran across the city.
Remember, Sheffield station is likely to be electrified with 25 KVAC overhead wires in connection with running electric trains between London St. Pancras and Sheffield.
If the four bay platforms at Sheffield station, were to be electrified, then these would be ideal for recharging any battery-electric trains or tram-trains, that terminated in the station.
Battery-Electric Trains Between Manchester And Sheffield
Consider.
- Manchester Piccadilly station is already fully electrified.
- Currently, all Manchester Piccadilly and Sheffield, terminate in Platform 8 at Sheffield station.
- The distance between the electrification at Manchester Piccadilly and Platform 8 at Sheffield station is 40.2 miles.
- CAF are promising battery-electric versions of their Class 331 trains.
With a battery range of fifty miles, which is not outrageous, Manchester and Sheffield could be an electric service for the first time since January 1970, when the Woodhead route was closed.
FirstGroup’s Proposed London King’s Cross And Sheffield Service
This open access service might happen, although with this Government of all the Lawyers we have, who can predict anything.
- If it does happen, it is likely that the trains will be battery-electric Class 802 trains.
- These will be the same as those that will be run by Hull Trains.
- Battery range will be sufficient to handle Retford and Sheffield, which is 23.3 miles and much shorter than Temple Hirst junction and Beverley.
These trains will also need charging at Sheffield.
The current Sheffield and Adwick service terminates in platform 3 at Sheffield station, so this platform would probably need to have tramway electrification, so that it could charge the trams.
Updating Rotherham Parkgate Tram Stop
My preference would be for four tph passing through Rotherham Parkgate tram stop in both directions, so this would be a tram-train every seven minutes and thirty seconds, if there was only one platform as now.
I’m fairly sure, that Rotherham Parkgate tram stop needs to have a platform in both directions.
This Google Map shows the tram stop.
Note.
- The double-track rail line between Meadowhall and Doncaster curving to the South of the Rotherham Parkgate Shopping Centre.
- The Rotherham Parkgate tram stop on a spur from the rail line.
I am pretty certain, that a two-platform station could be squeezed in.
Innotrans 2024: Rolls-Royce Shows mtu Solutions For On-Track Energy Transition And Celebrates 100 years Of Rail Engine Business
The title of this post, is the same as that of this press release from Rolls-Royce.
These four bullet points, act as sub-headings.
- All mtu engine series for locomotives and railcars approved for sustainable fuels
- DB, RDC Autozug Sylt, Trenitalia and České dráhy use or test HVO
- Rolls-Royce celebrates 100 years of success with mtu rail drives
- More than 250 rail customers worldwide value the performance, compact design and low exhaust emissions of mtu systems
These are the first two paragraphs.
Rolls-Royce will be presenting its mtu-brand propulsion and service solutions at the international rail exhibition Innotrans in Berlin from September 24 to 27, 2024 in Hall 18, Booth 500. The company will be celebrating an anniversary at the same time: for 100 years, mtu products have been powering trains, including mainline and multi-purpose locomotives, high-speed trains and local transport railcars. On display will be sustainable propulsion solutions such as the mtu Series 4000 and 1600 engines for locomotives and the underfloor drive systems mtu PowerPacks for railcars, all of which are now released for sustainable fuels such as HVO. Rolls-Royce will also be presenting its repower and reman solutions.
100 years ago, Karl Maybach laid the foundation for the rail drive systems of today’s mtu brand with the world’s first high-speed diesel engine for railcars, the Maybach G 4a. Maybach also developed the GO 5 engine for the “Fliegender Hamburger” express train.
These are my thoughts.
Chiltern Railways Could Go Carbon-Neutral By Using HVO
In Vegetable Oil Fuelling Chiltern Railways Trains In UK First, I described how Chiltern Railways are running their Class 68 locomotives on HVO.
This move by Rolls-Royce mtu will allow all Chiltern’s Class 168 trains to be run on sustainable HVO, as they have Rolls-Royce mtu diesel engines.
Chiltern Railways Class 168 train fleet is as follows.
- 10 x 4-car
- 9 x 3-car
- 9 x 2-car
This will still leave Chiltern Railways Class 165 train fleet to be converted to sustainable fuel.
- 28 x 2-car
- 11 x 3-car
Note.
- There are 75 of these trains in service with Chiltern Railways and Great Western Railway.
- They are fitted with Perkins engines.
- Perkins engines are now owned by Caterpillar, who built the engines for the Class 68 locomotives.
As Caterpillar have the sustainable diesel technology, could they convert the Class 165 trains to HVO?
Cummins And HVO
Although this post is mainly about Rolls-Royce mtu, it would be convenient to put in this section about Cummins and how their diesel engines run on HVO.
The UK train fleet contains the following trains with Cummins engines.
- 10 x Class 175 train x 2-car
- 16 x Class 175 trains x 3-car
- 14 x Class 180 trains x 5-car
- 34 x Class 220 trains x 4-car
- 23 x Class 221 trains x 5-car
- 4 x Class 221 trains x 4-car
- 4 x Class 222 trains x 7-car
- 23 x Class 222 trains x 5-car
Cummins says this about their engines and HVO.
Cummins approves use of HVO fuel in all high-horsepower engines
(19L-95L), including the QSK19, K19, QSK23, QST30, QSK38, K38, QSK45,
QSK50, K50, QSK60, QSK78, QSK95, V903 and ACE for all industrial
markets. No engine modifications are required; engines currently in the
field can be used with HVO at any percentage.
It would appear that all trains with Cummins engines can be converted to run on HVO.
CAF And HVO
Class 195, 196 and 197 trains all have Rolls-Royce mtu diesel engines, so they will be able to run on HVO.
Hitachi And HVO
Class 800, 1801, 802, 805 and 810 trains all have Rolls-Royce mtu diesel engines, so they will be able to run on HVO.
Conclusion
If all diesel engines are to be converted to HVO, there is going to be a lot of HVO needed in the UK.
But many train fleets will be carbon-neutral.
The Anonymous Widower
