The British Rail Class 14 is a type of small diesel-hydraulic locomotive built in the mid-1960s. Twenty-six of these 0-6-0 locomotives were ordered in January 1963, to be built at British Railways' Swindon Works. The anticipated work for this class was trip working movements between local yards and short-distance freight trains.^[2] The good all-around visibility from the cab and dual controls also made them capable of being used for shunting duties. The order was expanded from 26 to 56 in mid-1963, before work had started on the first order. They were numbered D9500-D9555.^[5]
