In 1958 Brush Traction Ltd and Beyer Peacock 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 was subsequently purchased by BR. However no large scale orders resulted from these demonstrators.
