In 1976 Conrail inherited their fleet of 25 SD9's from Penn Central, who inherited them from the Pennsylvania Railroad. Built between 1957 and 1958, the SD9's were powered by a V-16 567C prime mover that produced 1,750hp. Conrail placed their SD9's in series CR 6900-6924. The SD9's were primarily hump-duty locomotives, until Conrail retired them in the early 1980's.
