British Rail Class 24
The British Rail Class 24 diesel locomotives, originally known as the British Railways Type 2, were built from 1958 to 1961. One hundred and fifty-one of these locomotives were built at Derby, Crewe and Darlington. The first twenty locomotives were part of the 1955 British Rail modernisation plan. This class was used as the basis for the more powerful Class 25 locomotives.
