First Vivarail production train enters final build stage
After a period of radio silence, Vivarail has announced that its long-awaited battery D-Train is in its final build stage and will be in passenger service by summer.
The two-car train is the first production battery unit in the UK, powered by two lithium ion batteries per car.
The project suffered delays when its first trial runs on the Coventry to Nuneaton line were pushed back from October 2016 to February 2017 as the approval process for its use on mainline services had proved to be more complicated than anticipated.
It was then derailed in December 2016 when a test train caught fire, delaying the trials further.
The incident required an investigation in partnership with RAIB and led to five partners announcing that they could no longer support the project.
However, in March 2017 the train completed its first test run and was back on track, and by May its first two trains were ready for sale.
In July last year, further funding was announced for the project, with the Accelerating Innovation in Rail grant competition recognising the company's progression developing battery technology for the rail industry and injecting cash.
The trains can be charged through the existing infrastructure of OHL or a third rail, or, for non-electrical lines, there is a static battery bank which has been developed as an alternative.
In either case, the train is charged automatically through a patented automatic charging point, which the company says will allow battery trains to replace diesel units with minimal time and effort.
The train is expected to be on the network, fully approved for passenger service, by this summer.
