The H100 series (H100形) is a Japanese diesel-electric multiple unit (DEMU) train type introduced by Hokkaido Railway Company (JR Hokkaido) to replace the ageing KiHa 40 series DMU cars.
[3] Based on the GV-E400 series DMUs on order by JR East, the H100 series trains are the first diesel-electric multiple units to be operated by JR Hokkaido, with diesel engines driving generators, which in turn power electric traction motors.
[1] Two single-car pre-series units were delivered from the Kawasaki Heavy Industries factory in Kobe in February 2018[4] and underwent test-running and evaluation until March 2019.
[1] In September 2019, deliveries of the full-production units commenced[5] and on 14 March 2020, passenger operations started with a total of 15 cars on the Hakodate Main Line between Oshamambe and Sapporo.
[3] In the fiscal years (April to March) 2020 and 2021, a total of 60 more cars are planned for construction.
