The British Rail Class 31 diesel locomotives, also known as the Brush Type 2 and originally as Class 30, were built by Brush Traction from 1957-62. Construction of the first locomotive was completed in the final week of September 1957, and the handing-over took place on 31 October.
The Class 31 entered service in November 1957, after the launch of the Class 20 locomotive and was one of the Pilot Scheme locomotives ordered by British Railways to replace steam traction.
They were originally built with Mirrlees JVS12T 1,250 bhp (930 kW) and 1,365 bhp (1,018 kW) engines and Brush electrical equipment, but the engines were not successful and in 1964 a programme of works commenced to re-engine the fleet with the English Electric 12SVT engines as used in the Class 37 de-rated to 1,470 bhp (1,100 kW) which was the maximum the electrical system could accept.
