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.
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.
