Maybe some here can help me out? I was just reading up on Conrail's SD80MAC's on a website and it had that Conrail had 28 of the locomotives and had ordered an additional 30 but when the merger went through NS and CSX forced Conrail management to change the order to SD70MAC's and SD70's ranther than keeping the Sd80MAC's. But why would they do this. The SD80MAC's have more horsepower the the SD70MAC which has 4000 horsepower. Can someone please fill me in about this? Thank you in advance.
