The Post Office shifting mail transport from trains to planes is what changed the economics.

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.
