[1] US Army 101 was built for the US Army for use in World War I by Baldwin Locomotive Works in 1918 and was under their ownership until it was donated to Korea in 1947.

In 1953, the 101 was recovered from damaged areas and reconstructed by the Army Transportation Corps, under the direction of Col. George Simpson.

Shannon, and Harold E. Fuller started talks with the Korean Republic about donating the engine to the National Railroad Museum.

On May 30, 1959, General Pershing was presented with a Certificate of Service from the Secretary of the Army.

It is one of only three surviving Pershing Class locomotives, the others being the Southern Pine Lumber Company No.
