The Turbotrain was any of several French high-speed, gas turbine trains. The earliest Turbotrain entered service in 1967, for use on France's SNCF intercity lines. There were several versions, four in total, with the last exiting service in 2005, and it is the Turbotrain that made advances possible for the TGV.

The UAC TurboTrain was an early high-speed, gas turbine train manufactured by United Aircraft that operated in Canada between 1968 and 1982 and in the United States between 1968 and 1976. (Amtrak disposed of the trains in 1980.) It was one of the first gas turbine powered trains to enter service for passenger traffic, and was also one of the first tilting trains to enter service.
