LNER Class A4 4498 Sir Nigel Gresley

Sir Nigel Gresley is an LNER Class A4 4-6-2 Pacific steam locomotive built at Doncaster Works in 1937 to a design of Sir Nigel Gresley, for operation on the London and North Eastern Railway. Its Doncaster Works number was 1863 and it was originally numbered 4498, becoming 60007 under British Railways. It was the 100th Gresley Pacific built, and by the account given it was named after its designer instead of receiving the name Bittern first suggested for it. It gained a double chimney and Kylchap double blastpipe on 13 December 1957. The locomotive holds the post-war speed record for steam locomotives on British Railways. It was withdrawn from service in 1966 and purchased for preservation the same year, and it is one of six A4s to be preserved.
