(Last of steam: The last operation of steam locomotives in revenue freight service was in July 1959. The railroad entered 1960 with 86 steam locomotives still on roster; 31 were retired during 1960, 25 during 1961, and 22 during 1962, leaving eight steam locomotives in 1963. Between 1963 and 1988, the five remaining 4-8-8-4 Big Boy locomotives were retired and donated for preservation, and in 1996, 4-6-0 1243 was donated for preservation, leaving 4-8-4 844 and 4-6-6-4 3985 in regular excursion service.)
