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.[1] The train is branded "Accum".[2]

Overview

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.[2] JR East hopes ultimately to replace all of the diesel trains used on the line with these trains.[3]

The two-car trainset is equipped with 190 kWh lithium-ion storage batteries,[2] 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.[4]

The first set, V1, was delivered from the Japan Transport Engineering Company (J-TREC) factory in Yokohama on 21 January 2014.[5] Test running commenced on 23 January, on the Utsunomiya Line, including running on battery power with the pantographs lowered.[6] It entered revenue service on the Karasuyama Line from the start of the revised timetable on 15 March 2014.[1]

In May 2015, the EV-E301 series was awarded the 2015 Laurel Prize, presented annually by the Japan Railfan Club.[7] A presentation ceremony was held at Karasuyama Station on 26 September 2015.[8]
