Southern Pacific Railroad (SP) number 5021 is an SP-2 class 4-10-2 steam locomotive built in 1926 by ALCO at their Schenectady, New York, shops. It is the only member of this class of SP locomotives to be preserved, and it is one of only four 3-cylinder locomotives preserved in North America.
It was designed to haul mixed freight and passenger trains over the Sierra Nevada range between northern California and Nevada. Later in its career, 5021 was shifted to service in Oregon, until its retirement in 1955. SP donated 5021 to the Railway and Locomotive Historical Society on March 8, 1956.
5021 is currently on static display at the Los Angeles County Fairgrounds in Pomona, California.
