4-6-2 Class A1 Gresley LNER Profile and Models

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 and later express 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 new Pacific locomotives were built at the Doncaster "Plant" in 1922 to the design of Nigel Gresley, who had become Chief mechanical engineer of the GNR in 1911. Between 1927 and 1947, all of the A1s were rebuilt as A3s, with the exception of No. 4470 Great Northern, which was rebuilt by Thompson in 1945 as Class A1/1. The sole surviving member of the A3s and A1s is 4472 (60103) Flying Scotsman. The locomotive was withdrawn from service with British Railways in 1963 and after being saved from scrap it was sold for preservation.
