==BR Class 50==
Fifty English Electric Type 4 (later BR Class 50) diesel locomotives were built by English Electric at their Vulcan Foundry Works plant in Newton-le-Willows between 1967 and 1968. When built they were numbered in the D4xx series. They later became BR’s Class 50, being allocated TOPS numbers in the 50xxx series. The class was nicknamed “Hoovers” because of the distinctive sound of the inertial air-filters with which the locomotives were originally fitted.
Initially the locomotives were used to haul express passenger trains on the West Coast Main Line (WCML) between Crewe and Scotland; that section not then being electrified. This often entailed ‘Multiple Working’, with two locomotives under control of a single driver.
By 1974 the northern WCML had been electrified, and the Class 50 fleet was being transferred to BR’s Western Region to work main line passenger services out of London Paddington.
The Class 50’s did not originally carry names, but in the late 1970s BR agreed to their being named after Royal Navy vessels with notable records in the First and Second World Wars.
Withdrawal of the class began in the early 1990s.
