George Jackson Churchward, who succeeded William Dean as the Great Western"s Locomotive, Carriage and Wagon Superintendent in 1902, was one of the giants among British locomotive engineers. He revolutionised locomotive design on the GWR and his ideas influenced practice throughout the country. He made bold advances in the design of valve gear and steam passages which significantly enhanced both the performance and the economy of GWR locomotives. In this pictorial history, Brian Haresnape succinctly describes the development, performance and use of every Churchward locomotive class. His comprehensive history is backed by a brilliant collection of black and white photos of Churchward engines. With list of rebuilds, list of named engines, and bibliography. 112 pages.
