The Santa Fe class 1480 consisted of 23 Atlantics, which they built in 1910 at their own factory in Albuquerque. They initially had a three-dome boiler, a Jacobs-Shupert firebox and a four-cylinder compound engine. The steam was taken from the rear dome, went past the sand dome into the front dome and from there via an external pipe into the reheater in the smokebox. Also noticeable was the long wheelbase between the second driving axle and the trailing axle. 

Their nickname among the crews was “Bull Moosers” and the area of operation was lighter express trains. Following the general trend of the time, 14 of the 23 were rebuilt from 1920 into superheated locomotives with two cylinders of the same size. The wheelbase between the second driving axle and the trailing axle was also shortened by more than three feet. The first was retired in 1926, the last in 1953.
