I know about the five RS2s which were EMD repowers. I am wondering if the Frisco ever had run-through or leased units which would have utilized RS or RSD units in the 1960s or 1970s? I am aware that they occasionally leased short line motive power. Cheers, Ben S.
I do not not believe that the Frisco used foreign road, ALCO road switchers on any its run-through trains. Nor am I aware of any leased motive power from any shoreline railroad.
Ben, From discussions I have heard by railfans much older than me, the general reliability of the Alcos probably would have kept them on home roads. Also, the Frisco would not have been interested in dealing with equipment that they no longer used or maintained, especially in the 1970s.
