LNER Class A3 2750 Papyrus was a 4-6-2 "Pacific" steam locomotive built for the London and North Eastern Railway (LNER) at Doncaster Works to a design of Nigel Gresley, entering service in March 1929. Primarily used to haul express passenger trains on the East Coast Main Line by LNER and its successor, British Railways, it is notable for achieving what was at the time a world record-breaking speed for a steam locomotive of 108 mph on 5 March, 1935. A fictionalized account based on the locomotive's service history and speed record, 2750: Legend of a Locomotive by H.C. Webster, was published in 1953 and reprinted in 2016.
