Maybe a connection out to Denver as well, but thats pushing it.Because of geography, I don't see how HSR from LA to Las Vegas, Salt Lake city & Denver is possible. Too many mountains with steep grades & curves in the way. From LA to Las Vegas may be a high density but slow speed route. The real attraction is to pull traffic from the interstate in all weather conditions. In this case the railroad would be some better than a 55-60mph average highway speed limit.
We have a similar problem in the southeast linking Nashville to the south or the east.
