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).
DRG Class E 19
The electric locomotives of the class E 19 (class 119 from 1968) were the fastest electric locomotives of the Deutsche Reichsbahn. In regular service, they were restricted to a maximum speed of 180 km/h, but the locomotives were designed for travel speeds of up to 225 km/h. At the time of their presentation, they were the most powerful single frame locomotives ever built.
