TheEV-E801 series (EV-E801系,EV-E801-kei) is a two-carbattery electric multiple unit (BEMU) train type operated byEast Japan Railway Company (JR East) on theOga Line inAkita Prefecture in northern Japan since 4 March 2017.[2] The train is branded as "Accum" (Akyumu).
The train is derived from the experimental817 series BEMU train developed byJR Kyushu, and will incorporate modifications to cope with the colder climate of Akita Prefecture.[3]
The two-car EV-E801 series train operates as anelectric multiple unit (EMU) under the 20 kV AC overhead wire of theOu Main Line betweenAkita andOiwake, a distance of 13.0 km (8.1 mi), and on battery power over the non-electrifiedOga Line tracks between Oiwake andOga, a distance of 26.6 km (16.5 mi), replacing existingKiHa 40diesel multiple unit (DMU) trains.[3] It can also be recharged via itspantograph at a 20 kV AC recharging facility specially built at Oga Station.[3]
The EV-E800 car is equipped withlithium-ion storage batteries with a total capacity of 360 kWh (at 1,598 V), and operates at a maximum speed of 110 km/h (70 mph) under overhead wires and at 85 km/h (55 mph) on battery power over non-electrified tracks.[3]
The two-car train is formed as shown below, with one driving motor ("Mc") and one driving trailer ("Tc") car.[4]
| Designation | Mc | Tc' |
|---|---|---|
| Numbering | EV-E801-1 | EV-E800-1 |
| Weight (t) | 38.1 | 37.5 |
| Passenger capacity (seated/total) | 40/129 | 40/127 |
The Mc car is fitted with one single-arm pantograph.[4]
Internally, the train usesLED lighting throughout.[3] Seating accommodation consists of longitudinal bench seating. Both cars have a toilet.[4]
Initial details of the new train were formally announced by JR East on 20 November 2015.[5] The train underwent evaluation and proving trials on the Oga Line prior to scheduled services in March 2017.[2][5] The two-car trainset was delivered from theHitachi factory inKudamatsu, Yamaguchi to Akita Depot in December 2016.[6]
On November 2, 2020, two new sets G2 and G3 were delivered from Hitachi and arrived at Akita depot on November 4. The sets were coupled to each other and transported by a freight locomotive.[7] Additionally on November 16, 2020, three more sets G4, G5, and G6 were delivered and arrived at Akita depot two days later.[8]
In December 2023, a winter snowstorm stranded sets G5/G6 in the middle of Oga Line at apassing loop station, requiring aDE10diesel locomotive to rescue both sets at the same time.[9]
