This "Mountain Type" coal-burning steam locomotive was built in 1927 by the Baldwin Locomotive Works. Then in 1941, it was converted to use oil. It was retired in 1953, having traveled over 2,585,600 miles.
The AT&SF used its 4-8-4s for regular passenger service from Los Angeles to Kansas City, with Kingman as a water stop. Since its main line stretching over 2200 miles (Chicago to California), the AT&SF had a real need for excellent motive power.
Finally in 1957, it was the last steam engine to travel the line to Kingman. On this last journey, the Santa Fe Railroad presented the engine to the city of Kingman.
