Yes, and I-81 has already turned much of the Valley into a truck nightmare. I hate the thought of more lanes and more traffic. The East Coast congestion is a real problem. More freight needs to move by rail, IMHO. More people too, though I know the automobile supremacists won't see it that way.
If the trains themselves were the special things they once were, aesthetically in and out as well as creature comforts, and they were also convenient for not just city people but suburban people, then maybe passenger trains might return to prominence. As it stands, though, it’s an effort for even day trips or vacationing, since access isn’t all that great. Need to rethink basic assumptions. I’d love to take the train on occasion, if it was pleasurable and rewarding. Can’t say that it is for the majority of the country right now.
The I-81 corridor is spread out. Rail does work for some cargo, but it won't work for moving people, especially not $500 round trip with 2-3 bus changes.
