British Rail 18100 was a prototype main line gas turbine-electric locomotive built for British Railways in 1951 by Metropolitan Vickers, Manchester. It had, however, been ordered by the Great Western Railway in the 1940s, but construction was delayed due to World War II. It spent its working life on the Western Region of British Railways, operating express passenger services from London Paddington station.
