The KiYa 143 (キヤ143形) is a four-axle B-B wheel arrangement diesel-hydraulic locomotive type operated in Japan since 2014 by West Japan Railway Company (JR West).

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]

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]

History

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]
