This dude is right in that there are really no other options besides beefing up the rail infrastructure.
I think people who are dead set against it have not seen how good it can be.
It's not a matter of if but of when. Late --caddie.
Let's face it -- highway congestion, overcrowded airports, and poor passenger rail service all have the same cause: people want to get from Point A to Point B, but none of them want to pay the true cost of getting from Point A to Point B. What makes transportation unique in engineering is that it is possible to provide mediocre, or even downright awful, infrastructure without incurring catastrophic results. Nobody in their right mind would knowingly work in a building that met only 75% of the building codes, yet everyone seems perfectly content to live with a transportation system that runs at no better then 75% of its needed capacity.
