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).
History of steam road vehicles
In 1858 Thomas Rickett of Buckingham built the first of several steam carriages. Instead of looking like a carriage, it resembled a small locomotive. It consisted of a steam-engine mounted on three wheels: two large driven rear wheels and one smaller front wheel by which the vehicle was steered. The whole was driven by a chain drive and a maximum speed of twelve miles per hour was reached. The weight of the machine was 1.5 tonnes and somewhat lighter than Rickett's steam carriage.
