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).
Royal Bavarian State Railways
The one example of the Bavarian S 2/6 engine was designed and built by Anton Hammel, an engineer at the Maffei Locomotive Works, within 5 months and was displayed to the public at the 1906 Nuremberg State Exhibition. After its return from the exhibition it was taken over by the Royal Bavarian State Railways on 21 November 1906. A few months later, in July 1907, it set the world speed record for steam locomotives, recording a top speed of 154.5 km/h on the Munich to Augsburg line. Since being taken out of service in 1925 it has been preserved in the Nuremberg Transport Museum.
