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).
Le Mistral (train)
Still steam-hauled in 1964, the "Mistral" was one of the fastest trains in France, with an "average" speed of on the Paris – Dijon section, as well as an average speed of 129 km/h on its Valence – Avignon section. It also had the distinction of being the train with the "world's fastest schedule for [a route of] over 500 miles", averaging on its Paris – Marseille section. Slower speeds on the more "rugged country" between Marseille and Nice brought the average speed down to over the full 1,086 km route from Paris to Nice, which was nevertheless a relatively high average speed for 1964. Soon after that, electrification of the route was completed, and "Le Mistral" began being hauled by modern electric locomotives; starting in 1969, it was Class CC 6500 locomotives. This change along with new passenger coaches increased the train's average speed and shortened the travel time, the latter going from 10 hours, 21 minutes, in 1964 to just over 9 hours in June 1969.
