"The monumental task of building California's bullet train will require punching 36 miles of tunnels through the geologically complex mountains north of Los Angeles."

"Crews will have to cross the tectonic boundary that separates the North American and Pacific plates, boring through a jumble of fractured rock formations and a maze of earthquake faults, some of which are not mapped. It will be the most ambitious tunneling project in the nation's history...."

"If it were one single mass of granite, it would be easy to drill through and provide structural support," said [Caltech geologist Leon] Silver, who trained the Apollo astronauts in lunar geology and pioneered the dating of the San Gabriel Mountains. "But everything in the arc has been bent, shoved, stretched, compressed and metamorphosed."

The mountain range lies in a giant crescent between two major faults, the San Gabriel and the San Andreas, which separates the Mojave Desert on the North American tectonic plate from the Los Angeles Basin on the Pacific plate. Between the two major faults are many secondary faults. Some are vertical strike-slip faults that move laterally, and some are thrust faults that move vertically. Some are horizontal, traveling through the ground at various depths....

The longest possible tunnel, described as one alternative in state documents, would stretch 13.8 miles under the Angeles National Forest. Assuming TBMs started at both ends and advanced at 20 feet a day for 261 days a year, the tunnel would take seven years to complete — finishing in 2026. At an advance rate of 10 feet a day, the time would double to 14 years....

"Nobody can sit here and tell you what something like this is going to cost over a 20-year period," [said Jeff Morales, the rail authority chief executive]. "Any big program like this is loaded with challenges. The day you hear me say I am comfortable is the day I am not telling you the truth or the day I have deluded myself."

That's at the L.A. Times, where the top-rated comments are: "Why is it that when we predicted this, we were callled [sic] flat Earth declinists, when were the right the whole time?" and "No one with a single brain cell ever thought this was rational. It is and has been a political boondoggle from day one. It's stunning to think environmentalists in CA would allow such a dangerous construction project."

Flashback to April 2009: "Obama unveils high-speed passenger rail plan... The president's plan identifies 10 potential high-speed intercity corridors for federal funding, including California, the Pacific Northwest, the Midwest, the Southeast, the Gulf Coast, Pennsylvania, Florida, New York and New England.... His plan would be funded in part through the recently passed $787 billion stimulus plan, which includes a total of $8 billion for improvements in rail service.... The city of Chicago, Illinois, would be the hub of the proposed Midwest Regional Rail System, which would stretch to Madison, Wisconsin, in the Northwest; St. Louis, Missouri, in the South; and Detroit, Michigan, in the East."

Wisconsin said no to that money. It was the single issue that caused me to vote for Scott Walker in 2010. Local media whined that we lost  $810 million, while California was "the big winner, with up to $624 million." California is now in the process of giving up hope that it can meet a $68 billion budget. The rail authority chief executive says it would be delusional even to believe you can project the ultimate cost.
