The Atchison, Topeka and Santa Fe Railway's 1158 class comprised two 2-6-6-2 articulated steam locomotives built in 1910 by the Baldwin Locomotive Works.[1] They were jointed-boiler locomotives, an experiment confined to the Santa Fe; the railroad considered it successful enough to build four of the later 3300 class locomotives with flexible boilers, but both classes were scrapped in the 1920s.[1][2]
