cali's site is nice, but an expensive rail line that parallels a major fault line while crossing a couple others is not the best use of money.
Don't tell that to the Japanese. :lol:
They've been doing exactly that thing since 1964 in a country with greater risk for earthquakes than California, and with several major earthquakes since '64 and no passenger injuries or major damage on the line, even on the routes designed and built with older 1960's-70's earthquake mitigation technology.
Taiwan also has a newer 185MPH high speed rail system that was engineered for that earthquake prone island nation. Half the rail system was stopped this past May after a strong 6.4, but service resumed a few hours later after the tracks checked out just fine. Larger 7.0+ earthquakes have hit Taiwan along their rail line over the last decade, and their modern engineering absorbed it as designed and service was restarted within hours.
The Italians also have plenty of experience in operating modern high speed rail with earthquakes and active volcanoes in mind. Of the six active volcanoes in California, three of them are relatively close to the HSR route alignment.
Believe it or not, Californians are aware there are seismic faults here. The California High Speed Rail Authority has designed and engineered that fact into the plans, which is why they've already spent just over 1 Billion on engineering and planning. (They obviously chucked a few of those bucks to the website designer too.) That's also why California's HSR system is projected to cost so much; lots of extra money needs to be spent to meet or exceed California's strict seismic building codes.
The Los Angeles region alone already operates a very extensive network of passenger rail service called Metrolink that has 512 miles of track with hundreds of locos and cars carrying 40,000 riders per day. It has operated for 20+ years through some very major earthquakes, with no major damage or passenger injury. San Francisco and San Diego also have passenger rail networks designed to deal with earthquakes, including the 40 year old, 4 mile long Transbay Tube sitting 135 feet under the icy waters of San Francisco Bay. It has survived major earthquakes just fine.
The threat of earthquakes has been engineered in the 21st century into practically a non-issue. :wave:
