MLW built these locomotives starting in 1959. Canadian Pacific rostered 47 RS-23 units. The RS-23 was mainly owned by CP, however there were shortline industrial owners as well. The RS-23 units were unique in that as built, they were equipped with two different versions of the MLW lightweight road truck. They were frequently interchanged with the regular AAR type B truck in their service careers, and units could frequently be found with one of each.
