The 6400 locomotive hauling the Royal Tour Train, May 1939. London, Ontario.

Royal Tour 1939

CN 6400 achieved the peak of its fame in 1939 when it carried King George VI and Queen Elizabeth on the Royal Tour across Canada and then went on display at the “World of Tomorrow,” the New York World’s Fair.

The Face of Modern Rail Travel:  Sleek and Streamlined

Manufactured at the Montreal Locomotive Works for Canadian National Railways (CNR) in 1936, this steam locomotive featured a semi-streamlined body — designed by National Research Council of Canada engineers — and a state-of-the-art steam engine. CN 6400’s sleek lines also made it a favourite in the CNR’s promotional material where it became the face of modern rail travel. By the late 1940s, though, the age of steam was coming to a close. CN gradually withdrew and scrapped most of its steam locomotives. It spared CN 6400 because of its technical and symbolic importance.
