The core cities on the DC BAL PHL NYC BOS route total 11.5 million, while LA + SF is only 4.5 million. Thats arguably the more important figure because the relative advsntage of rail diminishes if you have to drive in from the suburbs. Also, four of those five cities have well developed public transit systems centered around the rail station. Metro area total for the five cities is not including any other regions in the path is almost 40m versus about 20m for SF and LA.

A major premise of the California HSR plan is that it isn't just about the main HSR lines, but upgrades, improvements, and new lines for connecting conventional regional and commuter rail, light rail, and other public transit.
