it is very simple the cost is way too high and the the fares would cost more then airline tickets and the travel time would be far slower. California is not Japan the central valley is not very populated and can not be so do to the lack of water. Also the mountains are a major problem for trains since a train can’t climb mountains over 3% grade so either very long tunnels with a lot of maintenance or a lot of switchbacks slowing the trains and a much longer trips. Also last point the local public transportation system is not very good so unless you can bring your car you will need to rent one or use some car service (be is a cab company or ride service)
bottom line is it is a poor solution for a non-problem that has a better solution that is already being used airplanes

很简单,成本太高了,票价比机票还贵,而且旅行时间也要慢得多。加利福尼亚不是日本,中部山谷人口稀少,而且缺水。此外,山区对火车来说也是一个大问题,因为火车无法翻越坡度超过 3% 的高山,所以要么是需要大量维护的超长隧道,要么是会减慢火车速度的岔道,从而大大延长行程。还有最后一点,当地的公共交通系统不是很好,所以除非你能带着你的车,否则你需要租一辆车或使用一些汽车服务(如出租车公司或乘车服务)。
最重要的是,这不是一个解决问题的好办法,而更好的解决办法已经在使用飞机了。
