Southern Pacific 4449, also known as the Daylight, is the only surviving example of Southern Pacific Railroad's "GS-4" class of 4-8-4 "Northern" type steam locomotives and one of only two GS-class locomotives surviving, the other being "GS-6" 4460 at the National Museum of Transportation in St. Louis, Missouri. GS is an abbreviation of "General Service" or "Golden State," a nickname for California (where the locomotive was operated in regular service). The locomotive was built by Lima Locomotive Works in Lima, Ohio for the Southern Pacific 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. No. 4449 was retired from revenue service in 1956 and put into storage. In 1958, the Southern Pacific donated the locomotive to the City of Portland, Oregon. The City then put the locomotive on static display in Oaks Amusement Park, where it remained until 1974. After this, No. 4449 was then restored to operation for use in the American Freedom Train, which toured the 48 contiguous United States as part of the nation's 1976 Bicentennial celebration. The locomotive has operated in excursion service throughout that area since 1984. The locomotive's operations are based at the Oregon Rail Heritage Center in Portland, Oregon where it is maintained by a group of volunteers named the Friends of SP 4449. In 1983, a poll of Trains magazine readers selected 4449 as being the most popular locomotive in the United States. Revenue service No. 4449 was the last steam engine manufactured in Southern Pacific's first order of GS-4 (Golden State/General Service) locomotives. No. 4449 was placed into service on May 30, 1941, and spent its early career assigned to the Coast Daylight, Southern Pacific's premier passenger train between San Francisco and Los Angeles, California, but it also pulled many other of the SP's named passenger trains. After the arrival of newer GS-4s and GS-5s, No. 4449 was assigned to Golden State Route and Sunset Route passenger trains. 4449 was reassigned to the Coast Division in the early 1950s. One of 4449's career highlights occurred on October 17, 1954, when SP 4449 and sister Southern Pacific 4447 pulled a special 10-car train for the Railway and Locomotive Historical Society from Los Angeles to Owenyo, California, and return. In late 1955, after being one of the last few Daylight steam engines in Daylight livery,
