Soo Line 2718 is a H-23 class 4-6-2 "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.[1] It was one of six H-23 class Pacific steam locomotives built for the Soo Line.[1] In the Soo Line's naming scheme, 'H' indicated the Pacific wheel arrangement.[1] The H-23 were their last Pacific class built.[2] No. 2718 was mostly assigned by the Soo Line to haul passenger trains between Chicago, Illinois, Minneapolis, Minnesota, and Winnipeg, Manitoba.[3][4]

No. 2718 was retired from revenue service in February 1958, and shortly thereafter, it was donated to the newly-established National Railroad Museum of Green Bay, Wisconsin. The following month, No. 2718, along with Milwaukee Road 261, were maneuvered into the museum's site in W. D. Cooke Park of Ashwaubenon, and they became the museum's first exhibits.[3][4] Since No. 2718 was still in operating condition, the museum would occasionally use it to move other locomotives, rolling stock, and other equipment around the property until the early 1960s.[3][5] As of 2026, No. 2718 sits on static display inside of the National Railroad Museum's Victor McCormick Train Pavilion barn.[6][7]
