6th-batch locomotives, the Class DD14 was a single-end-cab design with a rotary snowplough unit at the cab end.
It was the first diesel-powered rotary snowplough built by JNR. The locomotives had two 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.
