Operations

The KiYa 143 locomotives are used as self-propelled snowplough units during the winter season, replacing ageing JNR Class DD15 and JNR Class DE15 locomotives, and for hauling non-revenue services during other periods with the snowploughs removed.[1]

Design

The KiYa 143 locomotives use the same 450 hp (340 kW) diesel engines and braking systems as JR West's KiHa 189 series diesel multiple unit (DMU) trains.[1]

The first KiYa 143, KiYa 143-1, was delivered from Niigata Transys in February 2014.[2] This was followed by KiYa 143-2 in March 2014.[3]
