Look there are places in the U.S. where high speed rail would work:

1)The Boston-NY-DC Corridor

2)Dallas-Houston-San Antonio

3) Chicago-Mid West

4) Intra state Florida

The problem is the terrain has to be flat. That's why Vegas/LA is a non starter. The climb/descent into the LA basin is a killer.

Same thing for LA-North. Got to get out of the LA basin. But LA-San Diego would work and makes sense.

To be honest, I'm not so sure about one through four. It would really depend on how much demand there is, to begin with, and assume that its mutually beneficially for both sides......it might not be.

Boston and NYC, could wind up being a massive waste, or hurting one at the expense of the other, and while I believe that the locations you named are probably the best case scenarios, I'm not convinced its worth that kind of gamble to find out, especially since there hasn't been that kind of high demand airline and bus wise with NYC and Boston.
