power outputs, the prototype nature of the locomotive would have required further investigation and development into a configuration which would have matched the convenience of the new double-ended diesel-electric locomotives then being built. Neither English Electric or British Railways were prepared to fund this work as they were committed to diesel-electric locomotives. They were rapidly becoming the future of rail traction with ever-improving power-to-weight ratios. Upon completion of the Shap test runs GT3 was returned to English Electric at Vulcan Foundry at the end of 1962 and stored. Following internal correspondence in September 1965 the locomotive was partially dismantled and its turbine and heat exchanger equipment removed. It was finally scrapped at Thos. W. Ward, Salford in February 1966 having been towed there, ironically, by a BR standard steam locomotive. Surviving Records The most complete record of the locomotive is contained in the paper written by its designer in 1962 and in his papers now held at the National Railway Museum Archives in York. Much of what had been written about the locomotive was based on conjecture until these sources became available; subsequently an article in Railway Magazine for December 2015 brought together an accurate and verifiable record of the locomotive. No detailed engineering drawings of the locomotives as built are thought to have survived, the York archive containing an internal memo instructing that these were to be returned to the Gas Turbine division of English Electric when dismantling commenced in 1965. Several articles with drawings have appeared in the railway modelling press since the locomotive was scrapped, but most appear to be based on a contemporary sectional view widely published at the time and are flawed with regard to details such as driving wheels (19-spoke), roof and side access hatches, cab rear, tender front and tender rear. The most accurate drawing appears to have been a contemporary "Skinley" drawing produced with the assistance of JOP Hughes. A copy resides with correspondence between Hughes and Skinley in the JOP Hughes papers at the National Railway Museum. In recent years a 5-inch (127 mm) gauge turbine powered model of the locomotive has been built and exhibited in the UK.
