CR did what it had to do to run a class 1 with thousands and thousands of excess miles of track. Yes, mistakes were made, but unless you would have like seeing empty roadbed over Horseshoe Curve, along the Hudson river, and every other place a former CR main is alive and well, the fringes had to go. The big money was then and is now in intermodal, autoracks, unit trains and the like. The anthracite business was mostly short haul, just to Pier 124 in Philadelphia, and the hoppers couldn't be mixed with those used for bituminous loading, as the anthracite customers didn't want cross-contaminated shipments, neither would the other coal customers..
