Gas turbine locomotive turbine locomotive to be used on British Railways. The locomotive was to be built by the North British Locomotive Company and the turbine would be supplied by C. A. Parsons and Company. According to Sampson, the plan was to use indirect heating. The pulverized coal would be burned in a combustion chamber and the hot gases passed to a heat exchanger. Here, the heat would be transferred to a separate body of compressed air which would power the turbine. Essentially, it would have been a hot air engine using a turbine instead of a piston.

Gas turbine locomotive of the Advanced Passenger Train, was turbine-powered. Like the French TGV, later models were electric. This choice was made because British Leyland, the turbine supplier, ceased production of the model used in the APT-E. ALCO-GE built a prototype oil-fired gas turbine-electric locomotive in 1948. After demonstration runs it was acquired by Union Pacific, who were seeking a more powerful alternative to diesel for transcontinental trains. Union Pacific ran a large fleet of turbine-powered freight locomotives starting in the early 1950s. These were widely used on long-haul routes, and were cost-effective despite their poor fuel economy, due to their use of
