Creating new rail corridors is very expensive. It's not like when the original lines were laid down and we can just upgrade their paths. There are right of way issues that would displace millions these days.
But yes, rail is ideal where it is available. That's why we have a multi-modal delivery infrastructure.
What we will eventually see are convoys or "road trains" of many trucks heading down the interstate; possibly, but not necessarily, with one human in the first rig. They will then be broken up as they peel off for regional routes which will initially mean a human driver will take them over for those last mile deliveries in a city.
