The Santa Fe operated a large and varying fleet of steam locomotives. Among them was the 2-10-2 "Santa Fe", originally built for the railroad by Baldwin Locomotive Works in 1903. The railroad would ultimately end up with the largest fleet of them, at over 300. Aside from the 2-10-2, Santa Fe rostered virtually every type of steam locomotive imaginable, including 4-4-2 Atlantics, 2-6-0 Moguls, 2-8-0 Consolidations, 2-8-2 Mikados, 2-10-0 Decapods, 2-6-2 Prairies, 4-8-4 Northerns, 4-6-4 Hudsons, 4-6-2 Pacifics, 4-8-2 Mountains, 2-8-4 Berkshires, and 2-10-4 Texas. The railroad also operated a fleet of heavy articulated steam locomotives including 1158 class 2-6-6-2s, 2-8-8-0s, 2-10-10-2s, 2-8-8-2s, and the rare 4-4-6-2 "Mallet" type. The Railroad retired its last steam locomotive in 1959.
