The Conrail/CSX SD80MACs thrived on the Popes Creek Branch line in Maryland for a number of years, making our little/big orphaned branch line a fun place to fan. While denying the future, there some of us who were hoping one day these monsters would return, but alas, it isn't too be. I have been surprised for some time that NS didn't try to grab these units after CSX sidelined them.
Also denying the future, but I still hope that one day one of these unique Conrail units might find it's way to a museum intact in order to represent Conrail's exploration into the very high horsepower arena.
