LA Times: California’s bullet train could cost taxpayers 50% more than estimated — as much as $3.6 billion more. And that’s just for the first 118 miles through the Central Valley, which was supposed to be the easiest part of the route between Los Angeles and San Francisco.A confidential Federal Railroad Administration analysis, obtained by The Times, projects that building bridges, viaducts, trenches and track from Merced to Shafter could cost $9.5 billion to $10 billion, compared with the original budget of $6.4 billion.

No one here is really working toward the SF to LA run, neither SF nor LA want it.  This project is mostly about set asides, pension stuffing, local government bribery, and tearing down the best French Dip sandwich joint in Fresno.
