An anonymous reader quotes a report from the Guardian: The UK's first superfast-charging train running only on battery power will come into passenger service this weekend -- operating a five-mile return route in west London. Great Western Railway (GWR) will send the converted London Underground train out from 5.30am to cover the full Saturday timetable on the West Ealing to Greenford branch line, four stops and 12 minutes each way, and now carrying up to 273 passengers, should its celebrity stoke up the demand. The battery will recharge in just three and a half minutes back at West Ealing station between trips, using a 2,000kW charger connected to a few meters of rail that only becomes live when the train stops directly overhead. There are hopes within government and industry that this technology could one day replace diesel trains on routes that have proved difficult or expensive to electrify with overhead wires, as the decarbonization of rail continues. The train has proved itself capable of going more than 200 miles on a single charge -- last year setting a world record for the farthest travelled by a battery-electric train, smashing a German record set in 2021. The GWR train and the fast-charge technology has been trialled on the 2.5-mile line since early 2024, but has not yet carried paying passengers.
