According to the National Center for Policy Analysis and the Reason Foundation, the projected cost for the San Francisco to Los Angeles line has already risen from $33B to $43B, with the $7B spur to Sacramento most likely not even being built now. An S.F-L.A ticket that was formerly estimated to be $55 is now projected to cost $105.
And my favorite statistic: The California High-Speed Rail Authority estimates that ridership would be as high as 117 million passengers a year. To put this overblown number into perspective, the Amtrak line that serves the corridor connecting Boston-New York-Washington D.C. serves just 3 million passengers a year, and the entire Amtrak system around the entire country serves just 27 million.
That's OK, though. California is in great financial shape. We can afford these losses. /sarc
