retiredate=July1953 "The Great Bear", number 111, was a locomotive of the
Great Western Railway . It was the first4-6-2 Pacific locomotive used on a railway in the United Kingdom, and the only one of that type ever built by the GWR, who subsequently persisted with the tried and true4-6-0 locomotive type. The regular engine driver was Thomas Blackall, originally from Aston Tirrold, Oxfordshire. In 1924 the engine was rebuilt as a Castle Class locomotive and given the name "Viscount Churchill " though it retained its number. No 111 was withdrawn in July1953 . It was originally built to satisfy demands from the directors for the largest locomotive in Britain. In service, it was not an improvement on existing classes and had a highly restrictive route availability; it was restricted to the Paddington to Bristol main line.Churchward was disappointed to hear of "The Great Bear"'s destruction, and upon hearing ofNigel Gresley 's plans to construct a pacific for the Great Northern Railway, is said to have replied: "What did that young man want to build it for? We could have sold him ours!"External links
