Class 24

The British Railways Class 24 diesel locomotives, also known as the Sulzer Type 2, were built from 1958 to 1961. One hundred and fifty-one were built at Derby, Crewe and Darlington, the first twenty of them as part of the British Railways 1955 Modernisation Plan. 


This class was used as the basis for the development of the Class 25 locomotives. Initial deliveries were for operation in the Crewe and Derby areas, but fifteen of the initial twenty were diverted for use on the Southern Region to cover for delays in the Kent Coast Electrification scheme. As deliveries continued allocations were made to both the London Midland Region and Eastern Region. 


Class 24s took over the 'Condor' fast freight service between London (Hendon) and Glasgow (Gushetfaulds) in 1961 and later batches were assigned for use in the North East and the far North of Scotland, as well as Wales. The class were withdrawn progressively from 1973 to 1980 and four have been preserved.
