Southern Pacific 4449, also known as the Daylight, is the only surviving example of the Southern Pacific Railroad's GS-4 class of 4-8-4 Northern type steam locomotives and one of only two streamlined GS class locomotives preserved, the other being GS-6 No. 4460 at the National Museum of Transportation in St. Louis, Missouri. GS is an abbreviation of General Service or Golden State, the latter of which was a nickname for California, where the locomotive was used to operate in revenue service.

No. 4449 was built by Lima Locomotive Works (LLW) in Lima, Ohio for the Southern Pacific Railroad on May 20, 1941; it received SP's signature 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 on October 2, 1957, and donated to the City of Portland, Oregon in 1958. The city then put the locomotive on static display near Oaks Amusement Park at "Oaks Pioneer 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 since 1984.

The locomotive's operations are now based at the Oregon Rail Heritage Center in Portland, Oregon where it is maintained by a non-profit group of volunteers named "The Friends of SP 4449". In 1983, a poll of Trains magazine readers selected No. 4449 as being the most popular locomotive in the United States.
