History

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.[1] In the Soo Line's naming scheme, 'H' indicated the Pacific wheel arrangement.[1] The H-23 were their last Pacific class built.

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.
