LNER A3 pacific 4-6-2 steam locomotive 2502 Hyperion
The London and North Eastern Railway LNER Gresley Classes A1 and A3 locomotives represented two distinct stages in the history of the British 4-6-2 "Pacific" steam locomotives designed by Nigel Gresley. They were designed for main line passenger services, initially on the Great Northern Railway (GNR), a constituent company of the London and North Eastern Railway after the amalgamation of 1923, for which they became a standard design. The change in class designation to A3 reflected the fitting to the same chassis of a higher pressure boiler with a greater superheating surface and a small reduction in cylinder diameter, leading to an increase in locomotive weight. Eventually all of the A1 locomotives were rebuilt, most to A3 specifications. After the Grouping of 1923 Gresley adopted his GNR Pacific design as the standard express passenger locomotive for the LNER main line, designating it 'A1' within the LNER locomotive classification system. The first to be withdrawn was 60104 Solario in 1959, followed by 60095 Flamingo and 60055 Woolwinder in 1961. Otherwise, the class remained intact until 1962, and was still operating on express passenger work. The last class member to be withdrawn by British Railways was number 60052, Prince Palatine in January 1966.
