60022 Mallard, LNER A4 Class

A preserved LNER A4 Class streamlined 4-6-2 Pacific, built at Doncaster Works in March 1938. Withdrawn from British Railways service in April 1963 and preserved as part of the National Collection.

60022 Mallard holds the world steam speed record — 126 mph achieved on Stoke Bank, Lincolnshire, on 3 July 1938, during a braking test run. The record has never been beaten by a steam locomotive. Designed by Sir Nigel Gresley with streamlined bodywork developed in the National Physical Laboratory wind tunnel, she was outshopped from Doncaster just four months before the record run. She hauled East Coast Main Line expresses from 1938 until withdrawal in 1963, including the celebrated Elizabethan non-stop London–Edinburgh service in the early 1950s. In 2013 all six surviving A4 Pacifics were reunited at the NRM for the Great Gathering — the only time the six have been assembled together since being dispersed across two continents.
