KiYa 143


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

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.

Design

The KiYa 143 locomotives use the same diesel engines and braking systems as JR West's KiHa 189 series diesel multiple unit trains.

History

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