# GV-E400 series

The GV-E400 series (GV-E400系) is a diesel-electric multiple unit (DEMU) train type operated by East Japan Railway Company (JR East) in the Niigata and Akita areas of Japan from 2019.

## Design

The GV-E400 series trains are the first diesel-electric multiple units (not including hybrid train) to be operated by JR East, with diesel engines driving generators, which in turn power electric traction motors. The trains have stainless steel bodies and a maximum speed of 100 km/h (62 mph).
Internally, the sets use LED lighting throughout. Passenger accommodation consists of a mixture of longitudinal bench seating and transverse seating bays. The Niigata-area sets use pink seat moquette, and the Akita sets use blue seat moquette.
The design of the GV-E400 series served as the basis for the H100 series units operated by JR Hokkaido.
