LNER Class A1/A3
From Wikipedia, the free encyclopedia
The LNER Classes A1 and A3 represent two 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, a constituent company of the London and North Eastern Railway (LNER) 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 greater superheating surface along with a small reduction in cylinder diameter; all this led to an increase in locomotive weight. Eventually all the A1 locomotives were rebuilt to conform to A3 specifications.
The locomotives were given a variety of names, the first Great Northern being named after its parent company, others took the name of high-ranking railway officials, one after the company's most famous long-distance passenger train, the Flying Scotsman; but most had striking names taken from famous racehorses.
