Network SouthEast Class 50

The British Rail Class 50 is a class of diesel locomotives designed to haul express passenger trains at 100 mph (160 km/h). Built by English Electric at the Vulcan Foundry in Newton-le-Willows between 1967 and 1968, the Class 50s were initially on a 10-year lease from English Electric Leasing, and were employed hauling express passenger trains on the then non-electrified section of the West Coast Main Line between Crewe and Scotland. Initially numbered D400–D449 and known as English Electric Type 4s, the locomotives were purchased outright by British Rail (BR) at the end of the lease and became Class 50 in the TOPS renumbering of 1973.

The class gained the nickname "Hoovers" because of the noise made by the clean air plant at the No. 2 end, prior to refurbishment, which was likened to that of a vacuum cleaner, a name believed given to them by the staff at Paddington Station. Once the electrification from Crewe to Glasgow was completed the locomotives were moved to the Great Western Main Line (GWML) out of Paddington to allow the retirement of most of the remaining diesel-hydraulic locomotives then in use. As trains on the GWML steadily moved to High Speed Train operation from 1976, the Class 50s moved to hauling trains between London Waterloo and Exeter St Davids, and also trains from London Paddington to Hereford and Worcester via Oxford until the majority of those trains too were taken over by IC125 operation. The class was steadily retired from service in the late 1980s and early 1990s as their services moved to operation by second-generation Class 159 DMUs.

In 1986 the West of England Main Line came under the control of the Network SouthEast (NSE) sector, which saw the introduction of their bright blue, red and white livery. Two locomotives were repainted ready for the launch day on 10 June 1986, 50023 Howe and 50017 Royal Oak. In NSE livery, the nameplates were moved to a higher bodyside position.
