It would also be clever if the next generation corridor equipment planning that is in the bill that, IIRC, Congress has almost managed to pass, would take into consideration equipment that would operate at 250 MPH that can operate anywhere in the country that has catenary. But maybe I'm actually thinking of the generation after the next generation.
Regardless of whether California needs to mix freight or not, somewhere in the country, being able to run a high speed capable train on track shared with freight will be useful. In the greater Boston area, for example, if the North South Rail Link gets built so that an underground Central Station or North Station provides a connection to the Green Line in addition to the Orange Line, Amtrak might want to bypass Back Bay, in which case bringing the Fairmount Line back to four tracks (which it apparently once had) might be a good idea; two tracks could be used to make the various commuter stops, and two tracks could be used for trains that don't stop along the Fairmount Line, both freight and Amtrak (it's going to be very hard to find any other good way to get rail freight from Conley Terminal where the container ships get unloaded to the rest of the rail system, and keeping the freight off the platform tracks will make high level platforms possible without having to worry about the width of the freight cars).
I'm not sure how this is going to work nationally with platform height compatibility, since while I was trying to find the ACSES paper I stumbled across something saying that trains that operate faster than 125 MPH are not allowed to have internal stairs for low level platforms, and presumably California is not planning for northeast platform height (and really, northeast platform height is dumb for bi-level long distance trains).
