GWR fast-charging trial brings regular battery-only rail services a step closer
Great Western Railway has signed a deal with manufacturer Vivarail to trial new battery-charging technology on its network, paving the way for battery-only trains to run in regular passenger service in the future.
The trial, supported by Network Rail, will take place on the Greenford branch line later this year and test Vivarail’s trackside fast-charging equipment in an operational setting for the first time.
It is hoped that the project will demonstrate that the equipment works safely and reliably in a ‘real-world’ environment.
The use of batteries for extended operation has typically been constrained by their range and meant widespread implementation has, until now, not been feasible.
Fast Charge equipment will be installed at West Ealing Station later this year and tested with Vivarail’s battery-only Class 230 train, first showcased at COP26 last year.
The train has a range of up to 62 miles on battery power, recharging in only 10 minutes using the Fast Charge system in off-network tests.
When the train arrives at a station it connects automatically to the Fast Charge and the batteries receive charge while the train is prepared for its next journey.
The train was launched at COP26 in November and ran daily services throughout the international climate change conference in Glasgow, including an iconic trip across the Forth Bridge.
Testing on the Greenford branch line supports the Government and wider rail industry’s ambition to move towards net-zero carbon emissions by 2050.
The trial is supported by £2.15m funding from the Department for Transport’s Rail Network Enhancement Pipeline (RNEP).
Development of the Fast Charge technology also received funding from Innovate UK.
Rail Minister Wendy Morton said:
“We are world leaders in developing cutting edge green technology and this new zero-emission train supports our ambitious plan to move towards net-zero carbon emissions by 2050.
“Through our Plan for Rail and the Transport Decarbonisation Plan we are making the railways the backbone of a cleaner, more environmentally-friendly and modern public transport network.”
GWR Managing Director Mark Hopwood said:
“This is a really exciting development and underlines our commitment to reduce the carbon emissions of our train fleet with a view to removing all diesel-only traction from the network by 2040, in line with the Government’s Transport Decarbonisation Plan.
“We’re looking forward to working with our rail industry colleagues over the coming months to be able to rigorously test this battery train and charger on the Greenford branch line.”
Vivarail Managing Director Steve McBride said:
“Spearheading new green technology for rail is Vivarail’s forte, so I am delighted we are working with Great Western Railway on this demonstration of battery traction and automatic fast charging. The Greenford to West Ealing line will now lead the UK in bringing in new, emission-free battery electric trains combined with our world-leading charging system.
“Battery technology has been identified as a key part of the network’s solution to reach Net Zero and it is the ability of our charging system that provides the key to replacing diesel trains.
“I believe it will mark a step-change in showing the innovation within our industry. The support from GWR, Network Rail and the DfT to get this under way has been phenomenal.”
Network Rail’s Regional Managing Director for Wales and Western, Michelle Handforth, said:
“We are really excited for this new battery-powered trial to start and it highlights our commitment to providing a more environmentally-friendly way to travel.
“It builds on the success of electrification of the Great Western Mainline which has hugely reduced the number of journeys being made in diesel-only traction.
“We’re now looking forward to the challenge of getting the Greenford branch line ready for this new trial, which is another significant step forward for rail travel.”

Notes to editors
The rail industry launched a ‘We Mean Green’ campaign towards the end of last year, designed to encourage more people and businesses to choose greener train travel.
The Rail Delivery Group estimated that a 20% shift from rail to road would lead to an extra one million tonnes of CO2 emissions and 300 million hours stuck in traffic jams per year.
The campaign highlighted how:
- A single train removes up to 500 cars off our roads
- Travelling by train reduces carbon emissions by 7.7 million tonnes in the UK every year
- Train travel helps cut carbon emissions by two thirds compared to travelling by car
- Leaving your car at home and taking the train cuts carbon emissions by two-thirds
First Greater Western Limited, trading as “Great Western Railway” (GWR), operates trains across the Great Western franchise area, which includes South Wales, the West Country, the Cotswolds, across southern England and into London. GWR provides high speed, commuter, regional and branch line train services, and before the covid-19 pandemic helped over 100 million passengers reach their destinations every year. GWR was recently awarded an extension to its direct award franchise (called DA3), which shall run up to 31 March 2023, with an option to extend for a further year.

About Vivarail and its Fast Charge system
Vivarail has supplied its Class 230 trains in a variety of power formations and sold its first-ever battery train to the United States in 2021. The company specialises in battery traction and charging systems based around high performance lithium ion power batteries able to combine good range with a fast rate of recharge. The accompanying Fast Charge system is trackbased and comprises lengths of conductor rail which are only live when the train is in place above them. This is achieved through an automatic electronic ‘handshake’ between the train and charger that occurs as soon as the train comes to a stand and confirms that the train is in place and ready to receive charge. The energy is then passed to the conductor rails and into the train batteries. Once the train driver initiates the departure sequence the charger is automatically disconnected and the conductor rails are disconnected and become safe before the train moves away.
