Another workhorse was the 400 h.p. 9768 which, after the end of steam, became the prime mover on the Sterling, Colorado - Cheyenne, Wyoming branch line. Equipped with footboards fore and aft, she did all the switching at the 10 stations of the 108 mile run, and even bucked huge snowdrifts ion the winter. She could handle up to eight loaded freight cars westbound, climbing over a thousand feet. When her motors wore out she was replaced with small road switchers.
