Oh and by the way, the railroads are doing just fine hauling heavy freight. Its passenger business that died due to cars and airplanes, The lowest cost for hauling heavy loads long distance is by ship. Rail comes second. Trucks are third but more flexible as to where and when they can deliver. In my old corporate days we shipped heavy loads by rail whenever we could. Used trucks and air for convenience and short hauls. Air only for emergencies. I used to get most of my raw materials by rail and shipped finished goods by rail and truck. Rail still dominates in heavy and bulk on land.
