If its a tie, people will fly. Businesses are not going to force their employees to use a train.
Other cultures are different, but in this country, no one wants to ride a damned train. Especially since the train carries the stigma, accurate or not, of possibly having to ride with very poor or "dangerous" people.
If you can guarantee cheap oil for that entire time, then this is true. A oil price shock changes the math significantly.
Edit: Also, millenials and those immediately before them attitudes toward cars are pretty different than those before them. They aren't as in love with cars as those that come before them.
