==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.
