Mallard is the world's fastest steam engine, holding a speed record of 126 mp/h. He is a very popular exhibit at the National Railway Museum and is very well looked after.


Mallard was built on March 3rd, 1938, at Doncaster, where Gordon, Flying Scotsman, Spencer, and Green Arrow were built. On July the 3rd of that year, while undergoing tests, he established a world speed record of 126 mp/h.

After the decline of steam, Mallard was immediately preserved and put on display at the Museum of British Transport in Clapham, London. In 1975 he was taken to the National Railway Museum, where he remained until 1986, when he was overhauled and taken onto the main line. In 1988, the 50th anniversary of his record, he was retired and put back on display.Mallard returned to York in July 2011. He was due to travel to the DB Museum in Nuremberg, Germany for a speed exhibition later in the year, but the event was cancelled.


Mallard is a LNER A4 4-6-2. Spencer is also a member of this class.


Mallard is painted in the LNER's garter blue with red wheels and steel rims.
