Read more about these Pacific 4-6-2 engines designed for mainline passenger services on the GNR and LNER.
Designed by Sir Nigel Gresley, the LNER Gresley Steam Locomotive Class A3's were Pacific 4-6-2 engines designed for mainline passenger services on the Great Northern Railway, and later the London and North Eastern Railway.
Built at Doncaster in 1927 the A3 were broadly based on locomotive designs from America. In all, 78 of this class of locomotives were built the most famous example being 4474 The Flying Scotsman.
The Flying Scotsman was the most famous A3. It visited the United States and after being withdrawn from service entered in to private ownership. In recent years a major public appeal led to the NRM at York taking ownership.
