it probably won't be able to accommodate the 88% increase in freight projected by 2035, much less all long-haul trucking freight.
MonteQuest,
You do realize that if you double track, single track line you triple the capacity. And for inter-modal traffic when you double stack, you double capacity. Giving you a 600% increase across that section of line, not counting any speed increases from improved and new track. If the money is there, the investment will be made, and the capacity will be created.
One thing for sure, the interstate system will certainly not be near doubled to account for this 88% increase in traffic, while the no new taxes philosophy in maintained in the US.
Just for the record, we are not talking about all freight traffic going by rail. High security, high cost, very time dependent, over sized, and awkward loads will always be dominated by road. Part loads under 500 mile are also dominated by road. Less densely populated areas will be road based as well .
I am sure you could also come up with some other categories that will favour road base transport, but the rail system has grown rapidly as the price of fuel has risen, and computerized tracking systems have decreased the time in transit. Taken to the logical conclusion, the US freight system could come down to a hub and spoke system, where rail delivers to the hub and the trucks run the spokes, up to 100 to 300 mile, while trucks could be running up to 500 mile point to point.
