    I have seen the 220 mph alignment aross Tehachapi. Lots of tunnels. I do not know how public this study is at this point. so I am saying nothing more on the discussion. The reality is that once you decide to go much above 50 mph, you have so much tunneling and bridges the step between say around 80 mph and 200 mph is not that great in cost.
