The running time is 26 minutes, not much 90 mph. anywhere...

But I do agree that we should do much of what you propose, short term at San Clemente.

It's too bad that sensible projects like the DT extension from Serra was "stopped cold" by what were about 20 local Nimby's, rling up the mobs with lies, who many to scare OCTA's staff into cowering quivering terror. It's too bad that we are just completing a small handful of LOSSAN north project that were first planned over 25 years ago. Time flies in life and this now almost "geological" time scale of inaction in modernizing LOSSAN is longer working... The proof of which is that no trains" will be operating again, today...."

The true level of long range plannng that we have failed to do for LOSSAN since the demise of American High Speed Rail in 1983 has been a catastrophe, which has left us in the present situation.

How about we think about new options, like giving Brightline a 50 year franchise on LOSSAN, and they raise the $12 billion or so necessary, to fully bring LOSSAN up to first world rail passenger standards that would carry those 100,000 daily riders that American High Speed Rail identified, who could/would potentially be daily users of a truly first world level of rail service in a corridor like LOSSAN?
