After 22 months of testing, the UK's first battery-only train has recently entered scheduled service with the GWR. Its special feature: at one of the terminus stations, the multiple unit recharges its battery in just a few minutes using fast-charging technology.

The Great Western Railway (GWR) in the United Kingdom, like many railroad companies in Europe, is about to change the generation of rolling stock it uses. The old diesel multiple units are reaching the end of their service life and are to be replaced by more environmentally friendly alternatives. However, the operator wants to avoid the high costs of complete electrification. GWR, which operates an extensive route network between London and south-west England, sees the use of a fast-charging battery-only train as a possible solution, i.e. a vehicle that does not require an overhead line or side conductor rail and can be recharged stationary.
