I too would agree that Itchy's forecast has some merit to it. Hell, already today we have advanced diesel electric locomotives that literally get over 300 miles per one gallon of fuel. But rail has bigger limitations then air travel and I don't see it as a replacement for pax travel. Because as you said you would have to build the infrastructure. And even interconnecting existing rail lines to provide high speed pax service to the same number of cities and towns that have scheduled air carrier service today would be a monumental undertaking vs creating new pax lines altogether.
