How nice to be able to agree, even a little, with something JMH posts here. In fact rail IS far more fuel-efficient at moving goods than the interstate system. Once it's rolling. But you have to go back to the inception of the Interstate System to understand why rail has been ignored in favor of trucking. That system was devised for national security purposes. In case of attack or sabotage, a truck can easily be detoured while a train cannot. Blame WWII experience in stopping German transport.. as well as the Autobahn. From a commercial view, think of all those rail crossings. Not to mention time spent in freight car switching; only recently have switching systems developed that can route freight efficiently.... roughly the same time as spent in dropping trailers and hooking them up again. In addition, 'Just-in-Time' manufacturing methods have made matters worse. JIT makes sense from a bean-counter perspective, but places production at risk if the slightest delay occurs at any point in the process. For JIT, rail just doesnt cut it.
