GWR Battery-Powered Trains Could Be Used In Future
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Battery-powered trains could be used more frequently after a successful trial by Great Western Railway (GWR).
These three paragraphs give more details.
The rail company says using former underground trains and a rapid-charging system has shown the technology could replace its existing diesel fleet.
The year-long trial was held in west London but the trains will eventually be rolled out in the Thames Valley.
GWR says it can now prove the concept works and hopes to take the initiative to government.
A couple of weeks ago, I used similar trains between Wrexham Central and Shotton stations, which I wrote about in Vivarail Trains And Wrexham Central Station – 6th June 2025.
Vivarail Trains And Wrexham Central Station – 6th June 2025
From Chester, I took a train to Wrexham General station. From there I took a Vivarail Class 230 train to Wrexham Central station and then on to Shotton station.
These are some of the pictures I took.
Note.
- Time was tight at Wrexham Central station.
- But Wrexham Central station looked to be a good example of a tidy one-platform station built into a shopping centre.
- The Vivaral Class 230 train appeared to have worn well.
- From what I saw, it would be fairly easy to put up a short length of overhead line to charge battery-electric trains.
I should have given myself more time.
Changing For Chester At Shotton Station – 6th June 2025
From Wrexham Central station, I took the Borderlands Line to Shotton, where I changed to a train for Chester.
This Google Map shows the station.
Note.
- The station logo in the top-right corner of the map indicates the low-level station on the North Wales Coast Line.
- The second logo at the bootom of the map indicates the high-level station on the Borderlands line.
- It was quite a long walk between the two pairs of platforms.
- There were no lifts or facilities.
The Wikipedia entry for Shotton station gives this summary of future plans.
In March 2015 Network Rail published the draft version of their Welsh Route Study. It contained a proposal to build a new interchange station that would replace the existing High and Low Level stations, allowing for greater connectivity between the North Wales Coast Main Line and the Borderlands Line. The document recommended a transport planning study to establish the cost, feasibility and benefits of the proposed scheme.
In £2.1bn North Wales Rail Overhaul Plans Unveiled, match funding for step-free access at Shotton station is mentioned.
It certainly is a station in need of improvement. Especially, where step-free access is concerned.
It also needs a few more trains, as I waited an hour.
£2.1bn North Wales Rail Overhaul Plans Unveiled
The title of this post is the same as this article on the BBC.
This is the sub-heading.
A £2.1bn plan to overhaul north Wales’ railway network has been unveiled by Welsh Transport Secretary Ken Skates, but with no funding commitment from the UK government so far.
These three introductory paragraphs add more detail.
The proposals include more services, the introduction of pay-as-you-go “tap in tap out” technology, electrification of lines and a Metro-style service linking Wrexham and Liverpool.
Promising the plans would mean “better stations and more trains”, Welsh ministers have committed an initial £13m, with substantial UK government cash needed to realise the proposals.
The UK government has been asked to comment.
Having lived in Liverpool for seven years, I can understand how this upgrade will benefit Wales and also bring the area closer to Liverpool and Merseyside, to the benefit of the wider region.
There is also this press release from the Welsh Government, which is entitled “METRO IS GO” with Network North Wales.
This press release says plans include.
- Commencing work on the line between Wrexham and Liverpool as the crucial first phase of delivering metro services direct between the two cities.
- Doubling train services between Wrexham and Chester next May.
- Bringing forward the introduction of 50% more services across the North Wales mainline from December 2026 to next May – resulting in a new service from Llandudno to Liverpool and extending the Manchester Airport service to Holyhead in place of Llandudno.
- Upon completion of rail line works at Padeswood, increase train services between Wrexham and Bidston to 2 trains per hour within the next three years, ahead of the introduction of 4 trains per hour that will run direct between Wrexham and Liverpool by 2035.
- The existing Borderlands Line will also be renamed the Wrexham – Liverpool line.
- Key stations on the Wrexham – Liverpool line will be improved in the next 12 months.
- Trains operating on the Wrexham – Liverpool line will be wrapped to reflect the communities and football clubs they serve.
- Introducing Pay as You Go tap in tap out technology – covering connections between Gobowen and Rhyl, and along the full length of the Wrexham -Liverpool line
- Working with Network Rail to determine the feasibility of a rapid delivery of a new test railway station at Deeside Industrial Park, to gauge demand for permanent services to the park.
- A new, multi-million pound electrification innovation fund to develop a plan to decarbonise the railway in North Wales and enable more frequent metro services and additional stations
- Match funding for step-free access at Shotton and Ruabon stations.
- Working with local authorities to develop plans for Gateway multi-modal interchanges at Holyhead, Bangor, Caernarfon and Wrexham.
- A new T13 bus service – connecting Rhyl, Ruthin, Denbigh and Wrexham.
- Examining options to re-open stations and build new stations to serve employment growth areas.
- A new bus network specifically designed to link communities with industrial estates in the Flintshire and Wrexham Investment Zone.
It all seems very comprehensive.
The Current Wrexham And Liverpool Route
This OpenRailwayMap shows the railways of North Wales between Chester, Flint and Wrexham Central.
Note.
- Wrexham Central station is at the bottom of the map indicated by the blue arrow.
- Chester is in the North-East corner of the map, where three orange tracks meet.
- The orange track running East from Chester is the North Wales Coast Line to Crewe
- The orange track running West from Chester is the North Wales Coast Line to Shotton, Flint and then on to Llandudno, Bangor and Holyhead.
- The orange track running South from Chester goes to Wrexham.
- The yellow track running North from Chester is Merseyrail to Liverpool.
- Flint station is in the North-West corner of the map, with Shotton station between Chester and Flint stations.
- The yellow track running North from Wrexham Central station to Shotton station is the Borderlands Line to Bidston for Liverpool.
This second OpenRailwayMap shows the two Wrexham stations and the lines to Liverpool and Chester.
Note.
The orange track running North-South is the Chester and Shrewsbury Line, which runs through Wrexham General station.
The yellow track running North -West is the Borderlands Line to Shotton and Bidston for Liverpool.
Wrexham Central station is on an extension of the Borderlands Line.
This third OpenRailwayMap shows where the Borderlands Line crosses the River Dee on the Hawarden Bridge.
Note.
- Running across the South-West corner of the map is the River Dee.
- The orange track in the South-West corner of the map is the North Wales Coast Line between Chester and Holyhead.
- The yellow track is the Borderlands Line between Wrexham and Bidston for Liverpool.
- The Borderlands Line crosses the River Dee on the Hawarden Bridge.
- Shotton station is a poor interchange between the two lines.
- Hawarden Bridge station is North of the river.
This fourth OpenRailwayMap shows where the Borderlands Line joins Merseyrail’s Wirral Line at Bidston station.
Note.
- Bidston station is in the vNorth-West corner of the map.
- The yellow track running West from Bidston station is Merseyrail to West Kirby.
- The yellow track running South from Bidston station is the Borderlands Line to Wrexham.
- The yellow track running North from the triangular junction to the East of Bidston station is Merseyrail to New Brighton.
- The yellow track running East from the triangular junction to the East of Bidston station is Merseyrail to Liverpool via Birkenhead North, Birkenhead Park, Conway Park and Hamilton Square stations.
- Birkenhead Central station is in the South-Eastern corner of the map and is on Merseyrail’s branches to Chester and Ellesmere Port stations.
Services from Chester, Ellesmere Port, New Brighton and West Kirby all combine at Hamilton Square to go round the stations under the centre of Liverpool; James Street, Moorfields, Lime Street, Central and James Street (again).
Wrexham And Liverpool Improvements
These plans concern the Borderlands Line or the Wrexham and Liverpool Line.
- Commencing work on the line between Wrexham and Liverpool as the crucial first phase of delivering metro services direct between the two cities.
- Upon completion of rail line works at Padeswood, increase train services between Wrexham and Bidston to 2 trains per hour within the next three years, ahead of the introduction of 4 trains per hour that will run direct between Wrexham and Liverpool by 2035.
- The existing Borderlands Line will also be renamed the Wrexham – Liverpool line.
- Key stations on the Wrexham – Liverpool line will be improved in the next 12 months.
- Trains operating on the Wrexham – Liverpool line will be wrapped to reflect the communities and football clubs they serve.
- Introducing Pay as You Go tap in tap out technology – covering connections between Gobowen and Rhyl, and along the full length of the Wrexham -Liverpool line
- Working with Network Rail to determine the feasibility of a rapid delivery of a new test railway station at Deeside Industrial Park, to gauge demand for permanent services to the park.
- A new, multi-million pound electrification innovation fund to develop a plan to decarbonise the railway in North Wales and enable more frequent metro services and additional stations
- Match funding for step-free access at Shotton and Ruabon stations.
- Examining options to re-open stations and build new stations to serve employment growth areas.
There looks a lot to do, but none of the actions would appear to be that large and expensive.
Running Class 777 Trains Between Wrexham Central Station And Liverpool City Centre
Consider.
- There is no way, that the Office of Road and Rail will allow any more third rail electrification.
- Class 777 trains could be fitted with pantographs, if the trains need to be charged on the tracks past Bidston station.
- Siemens Mobility have developed a Rail Charging Converter, that I wrote about in Technology Behind Siemens Mobility’s British Battery Trains Hits The Tracks.
- I suspect Stadler have some similar technology for the Class 777 trains.
- Wrexham Central station is a single platform station.
- Bidston and Wrexham Central stations are 27.5 miles apart or a 55 mile round trip.
- In New Merseyrail Train Runs 135km On Battery, I describe how a Class 777 train ran for over eighty miles on battery power.
In Liverpool City Centre, trains would join services from Chester, Ellesmere Port, New Brighton and West Kirby and go round a loop through James Street, Moorfields, Liverpool Lime Street, Liverpool Central and James Street.
This Google Map shows Wrexham Central station.
Note.
- The single track, with the platform alongside.
- There would be plenty of space on the North side of the track to put up a short length of overead wire to charge the trains.
- The station appears to be surrounded by a shopping centre.
One platform should be able to handle four trains per hour (tph)
This second Google Map shows Bidston station.
Note.
- Bidston station is indicated by the station symbol.
- Merseyrail’s line between West Kirby and Liverpool runs through the station.
- Trains to Liverpool take the Eastern point of the triangular junction.
- Trains to New Brighton take the Northern point of the triangular junction.
- Trains to West Kirby and Wrexham take the Westerly lines, from Bidston station.
Work will probably need to be done at the junction, where the West Kirby and Wrexham line split.
I discuss the work at Padeswood in Train Frequency Focus In North Wales Transport Commission’s Interim Recommendations.
It doesn’t seem to me, that to be able to run 2 or even 4 tph between Wrexham Central and Liverpool, is going to need a large budget. Although, a few extra Class 777 trains, with a battery-electric capability, will be needed.
But this corner of Wales will have one of the world’s first battery-electric international trains.
New And Improved Services And Stations
These plans concern new and improved services and stations on the Borderlands Line or the Wrexham and Liverpool Line.
- The existing Borderlands Line will also be renamed the Wrexham – Liverpool line.
- Key stations on the Wrexham – Liverpool line will be improved in the next 12 months.
- Trains operating on the Wrexham – Liverpool line will be wrapped to reflect the communities and football clubs they serve.
- Introducing Pay as You Go tap in tap out technology – covering connections between Gobowen and Rhyl, and along the full length of the Wrexham -Liverpool line
- Match funding for step-free access at Shotton station.
- Examining options to re-open stations and build new stations to serve employment growth areas.
Deeside Industrial Park Station
This is planned for Deeside Industrial Park station.
Working with Network Rail to determine the feasibility of a rapid delivery of a new test railway station at Deeside Industrial Park, to gauge demand for permanent services to the park.
This Google Map shows Deeside Industrial Park
Note.
Shotton station is in the South West corner of the map.
Hawarden Bridge station is indicated by the red arrow.
The double-track Borderlands Line runs between the two stations and then Northwards between the warehouses and factories of the estate.
This second Google Map shows the area to the North of the two stations in greater detail.
Note.
- Flintshire Bridge Converter Station is the Southern end of the 2.2 GW Western HVDC Link from Scotland.
- Toyota’s Deeside Solar Park.
- The Borderland’s Line running between the substation and the solar park.
It does appear there could be plenty of space for a station.
Network Rail on Merseyside certainly have access to to a temporary station, as these pictures show of one’s use at Liverpool South Parkway station, which I wrote about in Liverpool South Parkway Station Stands In For Lime Street.
Note.
- It was mainly built of scaffolding.
- It was long enough for an eleven-car Class 390 train.
It could certainly be rearranged to make a temporary two-platform station.
But why a temporary station?
- It may turn out, that Bidston and Wrexham Central is too long for battery-electric trains.
- But Deeside Industrial Park station would be about half-way, so an ideal place for a pit-stop.
- It’s also got plenty of electricity.
- Toyota might also want to see how it helps the operation of their engine plant.
Network Rail might want to try out the idea of building a temporary station elsewhere in the future.
Wales’ Inaugural Hybrid Train Service Launches On The Borderlands Line
The title of this post, is the same as that of this article on Rail Technology Magazine.
These are the first two paragraphs.
Today marks a historic day for the Welsh rail sector, seeing the introduction of the first battery-hybrid trains used in regular passenger service on the Borderlands Line between Wrexham and Bidston, as announced by Transport for Wales (TfW).
The inaugural service for the Class 230 trains left Wrexham Central at 07:31, following months of testing and crew training.
Unfortunately, it didn’t go very well, as some trains were late and there were several rail replacement buses and cancellations.
I’m afraid, Vivarail’s ambitious project is starting to look like a heroic failure.
Could Stadler Rescue The Borderlands Line?
Perhaps the solution for the Borderlands Line, which is only 27.5 miles each way, is to ask Stadler for an estimate to extend Merseyrail’s Class 777 trains to Wrexham Central station.
- Trains would use battery power between Bidston and Wrexham.
- Passengers would not need to change trains to go between Liverpool and Wrexham.
- Trains would go round the rail loop under Liverpool, where they would charge their batteries.
- There may need to be some form of charging in Wrexham.
I’m sure the good people Merseyside and North Wales wouldn’t object, but the politicians in Cardiff might!
The UK-Wide Need For Self-Powered Trains
Consider.
- The UK needs a substantial number of two-, three- and four-car self-powered trains.
- A proportion of these trains will run on partially-electrified routes.
- 100 mph trains would be preferable.
- Some routes would need trains capable of using third-rail electrification.
They are also needed urgently.
Will Mark 3’s Save The Day?
Consider.
- The only Mark 3 electric multiple units still running or in a state good enough to be converted are the thirty-four three-car Class 320 trains and perhaps fifty four-car Class 321 trains.
- Class 317 and Class 318 trains are probably too old to convert.
- A Class 319 train is a very inferior train from a passengers point of view to the Class 321 Renatus.
As some of these like the thirty Class 321 Renatus have been refurbished and given AC transmissions, it might be a good idea to build a few prototypes and try them out on various routes to assess their quality, reliability and performance.
But this route would only give about eighty three- and four-car trains.
It wouldn’t supply any two-car trains.
Sadly, the twenty-four two-car Class 456 trains, which could have been converted have all been recently scrapped.
Are There Any Other Trains That Can Be Converted?
There are several fleets of modern trains, that might be available.
- Four-car Class 350 trains
- Four-car Class 360 trains
- Four-car Class 379 trains
- Four-car Class 386 trains
There may also be some three- and four-car Bombardier Electrostars.
Again, there is a shortage of two-car trains, except for thirty-nine Class 466 trains.
- They are Networkers.
- They were built in the 1990s.
- They were refurbished ten years ago.
- They are third-rail trains.
- They are not in bad condition.
- Their operating speed is only 75 mph.
But they would probably be a hard train to convert and would only be a stopgap.
Conclusion
I am led to the conclusion, that there is a large gap in the UK rail network for a two-car train with this specification.
- Battery-electric operation.
- 100 mph operation
- Battery range of at least eighty miles.
- Quality interior.
- Ability to run on 25 KVAC overhead and/or 750 VDC third-rail electrification.
- Ability to add a third-car in the middle to create a three-car train.
Effectively, they would be a replacement for the Class 170 diesel trains.
New Merseyrail Train Runs 135km On Battery
The title of this post, is the same as that of this article on Liverpool Business News.
This paragraph gives the details.
Posting on social media site Linked In, Joaquim Font Canyelles, project leader at Stadler Rail, said: “Our new Merseytravel class 777 IPEMU (Independent Powered Electrical Multiple Unit) proved its strength after running 135 km fully loaded and without external current supply, which is much longer than we expected.
Note that 135 km is 83.9 miles.
These are possible routes, where the battery-electric trains could be deployed.
- Bidston and Wrexham Central – 27.5 miles
- Canada Dock Branch – 4.6 miles
- Chester and Crewe – 21.2 miles
- Chester and Runcorn East – 13 miles
- Ellesmere Port and Runcorn East – 10.8 miles
- Ormskirk and Preston – 15.3 miles
- Hunts Cross and Manchester Oxford Road – 27.1 miles
- Kirkby and Manchester Victoria – 30 miles
- Kirkby and Wigan Wallgate – 12 miles
- Liverpool Lime Street and Chester via Runcorn – 27 miles
- Liverpool Lime Street and Manchester Oxford Road – 31.5 miles
- Southport and Manchester Oxford Road – 37.8 miles
- Southport and Stalybridge – 45.5 miles
- Southport and Wigan Wallgate – 17.4 miles
Note.
- All routes could be done both ways with the exception of Southport and Stalybridge and possibly Southport and Manchester Oxford Road.
- Southport trains to Wigan and Manchester would charge their batteries at Southport.
- Central Liverpool and Wrexham Central would not need the change at Bidston.
- Hunts Cross and Preston via Central Liverpool would not need the change at Ormskirk.
- A Liverpool Lime Street and Manchester Oxford Road service would be possible.
Batteries can add a lot of range to a city’s railway system.
Conclusion
If Merseyrail can get hold of the routes to Crewe, Manchester, Preston and Wrexham, the Liverpool City Region will have one of the best metros for a city of its size.
