The best way to do it is to have regional train networks, and use planes for inter-region travel. For example you would have train networks like L.A.- S.F., Chicago-Minneapolis, Chicago-St. Louis, Austin-Houston-Dallas-San Antonio, N.Y.C.-Boston-D.C., etc.
Unfortunately, that won't work politically. It basically treats red states like oceans that should be flown over, and puts all the high-speed rail in blue states (except the Texas network). It is probably more fiscally responsible to finance these networks at the state level than at the federal level.
