Mainline steam trains in Great Britain
The most famous steam locomotive operating on the British main line is the 1923 built "Flying Scotsman". After being taken into public ownership in 2004, following a decade long refit it returned to mainline service in 2016. The fastest steam locomotive ever built, the 1938 built "Mallard", was also certified for main line operation briefly in the 1980s.
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.
