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

Rebuilding[change | change source]

It was rebuilt as an electric locomotive in 1958 and became British Rail Class 80. It was scrapped in 1973.
