British Rail Class D2/11

The British Rail Class D2/11 was a British class of locomotive designed in 1958 by Brush Traction Ltd and Beyer Peacock, which co-operated to produce five prototype diesel-electric shunting locomotives of 0-4-0 wheel arrangement. They were intended to demonstrate a new generation of diesel shunters for industrial and mainline use. Two were loaned to British Railways for trials and one, number D2999,[1] was subsequently purchased by BR. However, no large scale orders resulted from these demonstrators.

Similar locomotives were built for industrial use, notably for steelworks in South Wales and Yorkshire. These were built by Brush Traction working with Bagnall. An example is preserved on the Middleton Railway.

D2999

D2999 was loaned by Brush to BR from January 1960 and was allocated to Stratford MPD where it was subsequently allocated to the goods yard at Globe Road and Devonshire Street. The locomotive proved popular at Devonshire Street and in September 1960 and subsequently purchased by them for further use. It was classified as British Rail Class D2/11 at this point, and remained there bar the odd maintenance visit to Stratford, until 15 October 1967 when it was withdrawn. It was fitted with a National M4AAV6 engine of 200 hp (150 kW), had a maximum speed of 18 mph (29 km/h) and weighed 30 long tons (30.5 t; 33.6 short tons).[2]

D9998

D9998 was on loan to BR for approximately a year from mid-1961. It was fitted with a Petter-McLaren engine of 200 hp (150 kW), had a maximum speed of 18 mph (29 km/h) and weighed 30 long tons (30.5 t; 33.6 short tons).
