You continue to display your stupidity for all to see, "commoncarrier." NS is the only U.S. carrier using RoadRailers. Wonder why? Others, and the former BN and UP experimented with them, but could not earn a sufficient return on investment. NS has or had a nice business moving beer south from Ohio and hauling southern manufactures on the backhaul. You've heard of backhaul haven't you? CSX never operated RoadRailers, although it did experiment with a similar technology. Whether a railroad can make a decent return on investment is a function of the length of haul, the commodity involved, the competitive issues. You stupidly look at a map and think you know all there is to know about railroading. You remind me of a snot-nosed kid beating his gums. As for CN short-haul Lasers, do you know what rates are charged? I don't, and I have had the opportunity to consult for CN on one of its acquistions. There is no single FAK rate, I'm reasonably certain. Differential pricing - something else I'm confident you don't understand if you've even heard the term - allows a railroad to discourage traffic that simply cannot pay a rate that provides a return on capital. "Capital," oh yes, that's the money that is invested in a business by the risk takers known as capitalists. CSX and NS - and other railroads like UP, BNSF, KCS, CP and CN do not do much short haul intermodal because at a certain length of haul and below, there is something called truck competition. "Railroads are competing with trucks on shorter lengths of haul than ever before because their service is at a level that customers are willing to pay, and trucks have so many problems of fuel use, pollution, driver shortages, etc., that their rates are going up, which gives railroads more opportunity to prosper. I realize that railroad posperity sends shivers up your spine, but them's the facts of life, lad. Once again, I urge you to take some time and learn something before you start inflicting you obstinate stupidity on this forum.
