The European mind does not comprehend how big and sparsely populated the American West is. You can't even pitch a tent in most places in the Alps, and why would you, when you just stop at a hut that has a staff and you can get fed and sleep in bunks with 20 other people? Meanwhile I can drive to numerous places where there isn't a structure or even another person in a 20km radius. No one is going to run a train to a place like that.
