Soo Line 2718 is a H-23 class "Pacific" type steam locomotive that was originally owned by the Minneapolis, St. Paul and Sault Ste. Marie Railway (the "Soo Line"), but operated by their subsidiary, the Wisconsin Central Railway.
No. 2718 was built in May, 1923 in Schenectady, New York. It was one of six H-23 class Pacific steam locomotives built for the Soo Line. In the Soo Line's naming scheme, 'H' indicated the Pacific wheel arrangement. The H-23 were their last Pacific class built.
No. 2718 was retired from revenue service in 1958 and was later donated to the National Railroad Museum in February 1958, were it would occasionally be fired up to move various rolling stock and other equipment around the property. Today, it sits on static display inside of the National Railroad Museum's Victor McCormick Train Pavilion barn.
There were six H-23 class locomotives built in May 1923. One of them is on display.
