No I acknowledged grain traffic was growing faster, but I also think that petroleum can be safely and efficiently transported by alternate means whereas the other products and materials on the chart cannot.
My other concern is what happens to rail traffic when coal prices start to move again. Even a small increase in coal traffic will have a big impact.
coal is moved much like crude... in dedicated unit trains... and as you can see there is a LOT moved by rail... but mines are being closed as plants are converted to natural gas... We shall see what happens... not counting on coal as part of a domestic energy plan is insane.
