The Senior Curator at the National Railway Museum in York, Anthony Coulls, says the Mallard exhibition of all surviving A4 locomotives – including two from America and Canada, is a once in a lifetime event.
The cosmetically restored Dwight D Eisenhower from America and the Dominion of Canada have been shipped to Britain to celebrate the 75 anniversary of the Mallard, which became the worlds fastest steam locomotive in 1938.
The Mallard was designed by Sir Nigel Gresley who was born in Netherseal in Derbyshire.
