History
The locomotive was built in 1926 by American Locomotive Company (ALCO) for the Southern Pacific Railroad (SP).[1][2] It was designed to haul mixed freight and passenger trains over the Sierra Nevada range between northern California and Nevada.[1][2] Later in its career, No. 5021 was shifted to service in Oregon, where it remained until its retirement in 1955.[1][2]
Southern Pacific donated No. 5021 to the Railway and Locomotive Historical Society on March 8, 1956.[1][2] In September 1961, it was briefly fired up and hauled various equipment around the Los Angeles County Fairgrounds.[2]
As of 2025, No. 5021 is on permanent display at the RailGiants Train Museum in Pomona, California.[1]
