The EV-E301 series (EV-E301系?) is a two-car battery electric multiple unit (BEMU) train type operated by East Japan Railway Company (JR East) on the Karasuyama Line and Tohoku Main Line since 15 March 2014. The train is branded "Accum".
Developed from the experimental "Smart Denchi-kun" battery railcar tested on the Karasuyama Line in 2012, the two-car EV-E301 series train operates as an electric multiple unit (EMU) under the 1,500 V DC overhead wire of the Tohoku Main Line between Utsunomiya and Hōshakuji, and on battery power over the 25.4 km (15.8 mi) non-electrified Karasuyama Line. It can also be recharged via its pantographs at a recharging facility specially built at Karasuyama Station. JR East hopes ultimately to replace all of the diesel trains used on the line with these trains.
The two-car trainset is equipped with 190 kWh lithium-ion storage batteries, and the train has a maximum design speed of 100 km/h (60 mph), although it normally runs at up to 65 km/h (40 mph) in service.
The two-car train is formed as shown below, with car 1 at the Utsunomiya end.
|Passenger capacity (seated/total)||48/133||48/133|
The Mc car has two PS38 single-arm pantographs.
Each car is mounted on a TR255D non-powered trailer bogie at the outer end, and a DT79 motored bogie at the inner end.
The first set, V1, was delivered from the Japan Transport Engineering Company (J-TREC) factory in Yokohama on 21 January 2014. Test running commenced on 23 January, on the Utsunomiya Line, including running on battery power with the pantographs lowered. It entered revenue service on the Karasuyama Line from the start of the revised timetable on 15 March 2014.
