Nigel Gresley
Sir Herbert Nigel Gresley (19 June 1876 – 5 April 1941) was an English railway engineer. He was one of Britain's most famous steam locomotive engineers, who rose to become Chief Mechanical Engineer (CME) of the London and North Eastern Railway (LNER). He was the designer of some of the most famous steam locomotives in Britain, including the LNER Class A1 and LNER Class A4 4-6-2 Pacific engines. An A1 Pacific, "Flying Scotsman", was the first steam locomotive officially recorded over 100 mph in passenger service, and an A4, number 4468 "Mallard", still holds the record for being the fastest steam locomotive in the world (126 mph).
GWR 3700 Class 3440 City of Truro
The GWR 3700 Class steam locomotive No. 3440 "City of Truro" was built in 1903 for the Great Western Railway (GWR) at Swindon Works to a design by George Jackson Churchward. It was partially rebuilt in 1911 and 1915, and renumbered 3717 in 1912. Although it is a point of contention, some believe the locomotive to be the first to attain a speed of 100 miles per hour (160.9 km/h) during a run from Plymouth to London Paddington in 1904.
