The locomotive spent years working on the Western Pacific Railroad hauling passenger trains and in freight service as well.
When it was retired in 1953, the Western Pacific dieselized and they sold her to the Southern Pacific railroad for spare parts, but they kept the tender and converted it into a steam generator for the rotary snowplows.
Today, the tender is stored at the Western Pacific Railroad Museum in Portola, California but the engine was scrapped in 1958.
