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 The exhaust from the diesel engine powered the gas turbine which drove the wheels through reduction gearing, jack shaft and side rods. Turbine power was considered for railway traction in the former Czechoslovakia. Two turbine-powered prototypes were built, designated TL 659.001 and .002, featuring C-C wheel arrangement, 3200 hp (2.4 MW) main turbine, helper turbine and Tatra 111 helper diesel engine. The first prototype was finished in February 1958 and was scheduled to be exhibited at Expo '58. This was aborted, because it wasn't ready in time. The first out-of-factory tests were conducted in March 1959 on the Plzeň–Cheb–Sokolov line.
