Southern Pacific 4449 is the only surviving example of Southern Pacific Railroad's (SP) GS-4 class of steam locomotives. The GS-4 is a streamlined 4-8-4 (Northern) type steam locomotive. GS stands for "Golden State" (a nickname for California, where the locomotive was operated in regular service) or "General Service." The locomotive was built by Lima Locomotive Works in Lima, Ohio, for SP in May 1941; it received the red-and-orange "Daylight" paint scheme for the passenger trains of the same name which it hauled for most of its service career. 4449 was retired from revenue service in 1957 and put on static display in Oaks Park, Portland, Oregon, the following year, where it remained until 1974. It was restored to operation for use in the second American Freedom Train, which toured the 48 contiguous United States for the American Bicentennial celebrations. Since then, 4449 has been operated in excursion service throughout the continental US; its operations are currently based at the Brooklyn roundhouse in Portland where it is maintained by a group of dedicated volunteers.
