The Canadian Railway Museum (French: (Le) Musée ferroviaire canadien), operating under the brand name Exporail in both official languages, is a rail transport museum in Saint-Constant, Quebec, Canada, on Montreal's south shore.

Established in 1961 by its owner and operator, the Canadian Railroad Historical Association, the museum maintains the largest collection of railway equipment in Canada with over 140 pieces of rolling stock.

There are also over 250,000 objects and documents from Canada's railway history in the collection which is maintained in the archives on the property.

One of the most notable artifacts is former Canadian Pacific locomotive #2850, with a 4-6-4 wheel arrangement, known as a "Hudson type".

In 1939, this particular locomotive was responsible for pulling the Royal train carrying King George VI and Queen Elizabeth on the westbound leg of their trip across Canada.
