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 demonstrate its wares to British Railways. It was designed by Vulcan engineer J. O. P. Hughes and the project had been started in early 1950s. Externally it resembled a steam tender locomotive, although, in the case of GT3, the tender carried diesel fuel.
