Design

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.[2] The trains have stainless steel bodies, and a maximum speed of 100 km/h (60 mph).

Interior

Passenger accommodation consists of longitudinal seating close to the doorways and 2+1 transverse seating further inside the cars.[2] The cars have universal access toilets.[2]

History

Details about the new trains were announced by JR Hokkaido on 12 July 2017.[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.[6]
