ATSF 3759 was delivered in 1928 as a 3751 class 4-8-4 passenger locomotive. Originally a coal burning locomotive with 73-inch drivers, the fleet was converted to oil in 1936 and rebuilt between 1938 and 1941 with 80-inch drivers. Its regular passenger run was from Los Angeles to Kansas City, with Kingman as a water stop on the way back to Los Angeles. Retired in 1953, the engine had traveled over 2,585,000 miles.
In February 1955, 3759 was brought out of retirement at the request of the Railway Club of Southern California for a special excursion run, dubbed "Farewell to Steam." It ran on February 6, a round trip between Los Angeles Union Station and Barstow, California with stops in Pasadena and San Bernardino and was the last Santa Fe revenue steam train to leave Los Angeles and to traverse Cajon Pass. After this trip, 3759 went back into storage, until Santa Fe donated the locomotive to the city of Kingman in 1957.
