That's a really good post, and here's a neat population map:

Look at Europe, Japan, India, and China versus the rest of the world. Their population density speaks well to not just a corridor, but a grid of regional and long distance passenger trains in addition to HST.
Our map does reveal that there are indeed corridors of density - Northeast, Carolinas, Florida, Chicago-Toronto, etc...
The biggest problem right now is that every year we write a check for trains that cover vast swaths of the emptiest land known. We keep hearing arguments about providing a service, not a profit, so that folks in remote areas can be served, or people that don't like flying can be served.
For every one person that is theoretically served out in western Kansas or Utah, there are two hundred in denser areas that could be better served. Each time the argument is made that "we have to serve Fred Smith in Nowhere", we are choosing to divert funds that could help 200 people get better access to jobs and work and customers if there were one more train out of Chicago, Charlotte, or Chattanooga to Detroit, Durham, or Duluth.
The new Acela: It's not Aveliable.
