Class 50
Delivered from Vulcan Foundry, Newton-le-Willows, between September 1967 and December 1968, the new 100mph diesel-electrics were developed from EE’s successful DP2 prototype with the intention of speeding up services north of Crewe to complement the accelerated electric timetable on the southern section of the West Coast Main Line. They were numbered D400-449, later 50001-50050 under TOPS
