> By contrast, the lack of density in CA would mean that aside from LA - SF (and a bit of traffic to and from Sacramento), you wouldn't likely have that sort of potential passenger-base.
Actually, since California has a large total population, and its mostly concentrated in a few major urban areas, what that means is you have a natural constituency for high speed rail with few stops, spending more time at speed.
LA (and San Diego) to SF (and Sacramento) is a lot.
But why would lots more people start going from LA to SF or on any of the other routes? As a comment to your previous comment below asks[1], what would the economic gain be?
There might be a bit more interaction between LA's entertainment industry and the Bay Area's tech industry, but how many additional people would be travelling for this purpose?
I expect that, given that the northeast corridor comprises the nation's capitol, its financial capitol and its academic capitol (the latter two also being high-tech centers), one would expect movement between these places and would want high-speed transport.
I just don't see a similar dynamic operating in CA. Sacramento cannot compare to Washington, D.C. and LA and SF are pretty self-sufficient, as I expect San Diego is as well.
