Soo Line 2718 is a Pacific class 4-6-2 steam locomotive that was originally owned by the Minneapolis, St. Paul and Sault Ste. Marie Railway (“Soo Line”), but operated by their subsidiary, the Wisconsin Central Railway.
The 2718 was built in May, 1923 in Schenectady, New York. It was one of six H-23 Pacific Class steam locomotives built for the Soo Line.
The 2718 was donated to the National Railroad Museum in February 1958. The museum used it for a few years to move cars around the grounds. It also saw limited service pulling the museum train.
There were six H-23 class locomotives built in May 1923. Two of them are preserved.
