If the freight rail system were as good as it should be, long distance trucking would be a rounding error instead of the dominant freight mode.
The passenger trains also carried mail, which helped make them profitable. Then the mail, and the money, moved to passenger planes.
Dunno if it will move by train or truck.
Probably too late to add much volume on the ground.
