Southern Pacific 2472 is a 4-6-2 Pacific type steam locomotive built by the Baldwin Locomotive Works for Southern Pacific Railroad (SP) in 1921. It had 4 leading wheels, 6 drivers, and 2 trailing wheels.
2472 and sister Pacific locomotives served the Overland Route from Ogden, Utah, to Oakland, California. On November 30, 1929, SP's Ogden shops added a feedwater heater to the locomotive, which increased its overall weight to 300,000 lb. 2472 again underwent a rebuild at SP's Bayshore shops in Brisbane, California (San Mateo County), completed on November 26, 1940, that increased its boiler pressure to 210 psi and its tractive effort to 45,850 lb.
After being replaced by the 4-8-2 "Mountain" type locomotives, 2472 and all other Pacific locomotives were sent to work Sacramento-Oakland, California passenger trains and San Francisco-San Jose, California commute trains, along with occasional freight service. The locomotive's revenue service life ended in 1957 when steam locomotives were being replaced by diesel locomotives, and on April 10, 1959, 2472 was donated to San Mateo County, which put 2472 on static display at the San Mateo County Fairgrounds.[1] It remained there until 1976 when a group of voulunteers decided to restore the locomotive.
In the 1990s and early 2000s, 2472 pulled several excursions and Caltrain specials such as the Trains for Tots, and even double-headed on an excursion with famed steam locomotive Southern Pacific 4449.
Southern Pacific 2472 recently received FRA-mandated boiler work at Hunters Point Naval Base in San Francisco, the former site of the Golden Gate Railroad Museum, which was recently evicted from this location. It is expected to be moved to the Niles Canyon Railway located in Fremont, California on the other side of the San Francisco bay.
SP 2472 is one of three surviving Southern Pacific 4-6-2 Pacific locomotives.
