The Class DD14 (DD14形) was a Bo-Bo wheel arrangement diesel-hydraulic locomotive type operated in Japan as a self-propelled rotary snowplough unit from 1961 to 2015 by the national railway company Japanese National Railways (JNR), and later by East Japan Railway Company (JR East). West Japan Railway Company (JR West), and Hokkaido Railway Company (JR Hokkaido).
Design
Based on the earlier Class DD13 6th-batch locomotives, the Class DD14 was a single-end-cab design with a rotary snowplough unit at the cab end.[1] It was the first diesel-powered rotary snowplough built by JNR. The locomotives had two 500 hp (370 kW) diesel engines. One engine could be used for propulsion with the other driving the rotary snowplough unit, giving a snow-clearing capacity of approximately 3,000 tonnes per hour, or the unit could be operated in multiple with a second locomotive allowing both engines to drive the rotary snowplough, giving a snow-clearing capacity of approximately 4,000 tonnes per hour.[1]

- DD14-300: 35 locomotives built between 1966 and 1979 by Kisha Seiso and Kawasaki Heavy Industries[1]
History
By 2005, only nine locomotives remained in service, all operated by JR East.[2] The last remaining locomotives in service, DD14 327 and 332, based at JR East's Nagaoka Depot, made their final run on 24 February 2014.[3]
