small number in service for hauling inspection specials, charter passenger trains, investor tours and other special trains. Five E9s are owned by the Illinois Railway Museum, in Union, Illinois. The operating units are often used pulling trains within museum grounds. The Union Pacific Railroad rosters three E9s: two A units, 951 and 949, and a B unit, 963B (built as UP E9B 970B), in their heritage fleet. They were rebuilt in 1993 with a single 2000 hp EMD 16-645E engine and upgraded electrical and control equipment for compatibility with more modern locomotives. Southern Pacific 6051, the last surviving SP E9, is preserved at the California State Railroad Museum and operates excursions hosted by the museum. CN owns and operates ex-Chicago, Burlington & Quincy E9A 9986A for its business train, painted in CN's heritage livery and numbered 103. Milwaukee Road 32A is owned and operated by the Friends of the 261, who acquired it in 2019. This unit was previously used on the Wisconsin and Southern Railroad as their 101.
