The Class 321 Renatus Fleet of electric trains could become a Battery Electric Multiple Unit (BEMU) thanks to a new deal between Eversholt Rail and Vivarail.

The 30 strong fleet is thanks to a £65m investment in AC traction, air con and interior upgrade.

These trains are currently in operation with Greater Anglia until the introduction of their new trains are complete.

Vivarail, who already has a reputation for its high quality battery powered trains here in the UK and America, will work with Eversholt Rail to develop a design to integrate battery power that will provide 20 to 30 miles of self-propulsion.

Allowing the 321s to operate on non-electrified or partly electrified lines allows for the opportunity to increase options for passengers.

Both Vivarail and Eversholt Rail has discussed the options with various operators and the Department for Transport. The case development will continue in 2022 and further investment in the fleet will be confirmed in due course.

Paul Sutherland, Client Services Director at Eversholt Rail said, “We are delighted to be working in partnership with Vivarail on this exciting project to develop our C321 fleet which will support the UK’s decarbonisation targets. We have a proud history of innovation and investing in our fleets to meet changing requirements, exploring the viability of integrating battery technology to the Renatus fleet is the natural next step. Battery trains offer an ideal solution for routes with partly and un-electrified lines, enabling the replacement of diesel trains and bringing the air quality and decarbonisation benefits.”

Steve McBride, MD of Vivarail, said: “Vivarail are delighted to be collaborating with Eversholt Rail Group on this exciting project. Working towards installing our latest generation battery technology into existing Class 321 Renatus units enables these trains to operate beyond the overhead wires, reducing reliance on diesel trains and reducing carbon emissions. Great British Railways is set to deliver the most ambitious changes in our railways seen in a generation. I am proud to say that Vivarail are ready for the challenge and look forward to contributing to the industry’s commitments for decarbonisation.”
