|Used in contracts:
| The Class 31 was one of the Pilot Scheme locomotives ordered by British Railways to replace steam traction. They were originally built with 930 kW and 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 1,100 kW English Electric engines. The locomotives were originally known as Class 30, but the re-engined examples became 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.|
