The British Rail Class 31 diesel locomotives, also known as the Brush Type 2 and previously as Class 30, were built by Brush Traction from 1957-62. They were numbered in two series, D5500-D5699 and D5800-D5862. Construction of the first locomotive was completed in the final week of September 1957, and the handing-over took place on 31 October. The first 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. Engines They were originally built with Mirrlees JVS12T 1, 250 bhp (930 kW) (D5500–D5519) and 1, 365 bhp (1, 018 kW) engines and Brush electrical equipment, but the engines were not successful and in 1964 D5677 was fitted with an English Electric 12SVT engine (similar to the 12CSVT used in the Class 37 but without an intercooler) rated at 1, 470 bhp (1, 100 kW). The trial proved successful, and between 1965 and 1969 the entire class was re-engined. The de-rated engine was used as it was the maximum the electrical system could accept. Classification The Mirrlees-engined locomotives were originally known as Class 30 under TOPS, with re-engined examples joining Class 31. The class was originally intended for service on the Eastern Region, but gradually became common in both the Western and London Midland regions too.
