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 D2999undefined, 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.
