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.

Steam turbine locomotive turbine failed after eleven years in heavy service. The Turbomotive was converted to piston drive in 1952, renamed "Princess Anne" and shortly after entering service was withdrawn following the deadly Harrow and Wealdstone railway accident in 1952. Another locomotive was built by Beyer-Peacock, using the Ljungström turbine by Fredrik Ljungström. Like one of Ljungström's early designs, the driving wheels were under the tender. Performance was disappointing, however, partly because of poor heating of the boiler. Another unit was rebuilt by the North British Locomotive Company. In its first incarnation (described below) it had an electrical transmission. Only a few tests
