In late 2012, a team of engineers attempts to move two historic locomotives across the Atlantic to the British National Railway Museum in York, United Kingdom. They are two of the six remaining A4-class steam engines: the Dwight D. Eisenhowser from the National Railroad Museum in Green Bay, Wisconsin and the Dominion of Canada from the Canadian Railway Museum in Montreal, Canada. Three other A-4s are also moved (not part of this episode) to join the Mallard at the British Nationial Railroad Museum for 2013 celebrations of the 75th anniversary of Mallard breaking the world speed record for steam. On July 3, 1938, the Mallard reached 126 mph.
