The EV-E801 series (EV-E801系, EV-E801-kei) is a two-car battery electric multiple unit (BEMU) train type operated by East Japan Railway Company (JR East) on the Oga Line in Akita Prefecture in northern Japan since 4 March 2017.[2]

Overview

[edit]

The train is derived from the experimental 817 series BEMU train developed by JR Kyushu, and will incorporate modifications to cope with the colder climate of Akita Prefecture.[3]

The two-car EV-E801 series train operates as an electric multiple unit (EMU) under the 20 kV AC overhead wire of the Ou Main Line between Akita and Oiwake, a distance of 13.0 km (8.1 mi), and on battery power over the non-electrified Oga Line tracks between Oiwake and Oga, a distance of 26.6 km (16.5 mi), replacing existing KiHa 40 diesel multiple unit (DMU) trains.[3] It can also be recharged via its pantograph at a 20 kV AC recharging facility specially built at Oga Station.[3]

The EV-E800 car is equipped with lithium-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]

Formation

[edit]

The two-car train is formed as shown below, with one driving motor ("Mc") and one driving trailer ("Tc") car.[4]

History

[edit]

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 the Hitachi factory in Kudamatsu, 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 a passing loop station, requiring a DE10 diesel locomotive to rescue both sets at the same time.[9]
