EE TYPE 5 CLASS 50

The Class 50 Diesel Locomotive, also known as English Electric Type 4, was a Co-Co configuration engine built by English Electric's Vulcan Foundry at Newton-le-Willows between 1967 and 1968.

They were designed for express passenger trains on non-electrified stretches of the West Coast Main Line A total of  50 locomotives were built and renumbered from D400 to 449, (later 50001 to 50050). They initially worked to Preston, Lancaster, Carlisle and Glasgow and were reallocated to the Western Region following electrification on West Coast Main Line.

Following the introduction of the HST’s in the West they were transferred to services out of London Paddington to Birmingham until the late 1970s. After refurbishment, they worked from Paddington and Waterloo. Withdrawal followed in the 1990s, but a few survive in preservation.
