- GWR plans to use it on the Greenford branch in west London, making use of a fast charger at West Ealing that will charge the batteries in just three and a half minutes. This fast charger is essentially a battery installed at the lineside which is trickle-charged from the electricity grid. It can then discharge quickly into the train's batteries through charging rails and then start recharging itself while the train is running in service.2024 March 6, “Network News: GWR '230' sets UK battery record”, in RAIL, number 1004, page 13:
