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.

British Rail GT3 British Rail GT3 GT3, meaning Gas Turbine number 3 (following 18000 and 18100 as gas turbines 1 and 2), was a prototype mainline gas turbine locomotive built in 1961 by English Electric at their Vulcan Foundry in Newton-le-Willows to investigate the use of its gas turbines in rail traction applications. It was designed by English Electric engineer J. O. P. Hughes in a project that started in the early 1950s. Externally it resembled a steam tender locomotive, although, in the case of GT3, the tender carried kerosene fuel. The designer stated the use of a traditional chassis arrangement and mechanical
