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.
Overview
It was of
4-6-0 wheel arrangement based on a
BR standard class 5 steam locomotive chassis and was fitted with an EM27L
gas turbine of 2700hp. It had a maximum speed of 90mph, weighed 123.5tons, and was painted in a
red oxide livery.
BR tested it at its
Rugby test centre and then on the former
Great Central Main Line around
Leicester and the
West Coast Main Line around the
Shap incline.
At the same time, Vulcan was fully engaged in manufacturing diesel-electric locomotives of many types (including the
Deltic). These were rapidly becoming the future of rail traction. Diesel-electrics do not need turntables, an advantage that the GT3 with its steam loco style layout could not offer.
BR decided to stay with diesel and electric traction, and GT3 was returned to
Vulcan Foundry at the end of 1962, where it was gradually dismantled. It was finally scrapped at T.W. Ward, Salford in February 1966 having been towed there by, ironically, a BR standard steam locomotive.
