Equipment Information

Rock Island 938 is an express passenger engine built for hauling heavy passenger trains at high speed. The 4-6-2 Pacific wheel arrangement was very popular for mainline passenger engines between 1910 and about 1930 and 938 is an exemplar of the type. At the end of its service life it was used pulling commuter trains in the Chicago area. The engine was retired to the grounds of a school in Oklahoma in 1954. It was purchased by IRM in 1995 and moved to Union in 1999.
