On 3 July 1938, A4 class locomotive Mallard raced down Stoke Bank at 126mph to set a new steam locomotive world speed record. That record still stands. In 2013, the National Railway Museum marked the 75th anniversary of Mallard's achievement with a series of commemorative events, including the July Great Gathering which reunited the record breaker with its five surviving sister locomotives. Only six of the 35 A4 locomotives built survive in the world. The NRM brought the Mallard together with Bittern, Union of South Africa, Sir Nigel Gresley and the temporarily repatriated Dwight D Eisenhower and Dominion of Canada from their home museums in Canada and the US.
