The class 52 was a diesel-hydraulic general-purpose locomotive of the British Railways (BR).
History and technology
British Railways decided - in memory of the success of the "Warship" series 42 and 43, which had been developed as a modification of the DB series V 200 - to invest in 74 more powerful diesel-hydraulic locomotives for hauling high-quality express trains.
In contrast to the design of the Deutsche Bundesbahn, namely to install larger engines in diesel locomotives of the same dimensions, the "Westerns" were extended to the C'C 'wheel arrangement.
The class 52 locomotives had drive units of the same size as the DB class 221 locomotives .
With their top speed of 145 km / h and high tractive effort of 319 kN, they were used in front of both express trains and heavy freight trains.
The last class 52 locomotive was parked in 1977.
Whereabouts
Seven class 52 specimens have been preserved in museums.
Others
The class 52 locomotives were originally painted in BR's Brunswick green. Little by little, all the machines were painted brown. Eventually they all got the typical BR paintwork in blue with yellow ends.
