Per this webpage,, there are about 3.7 million passengers annually between SFO and LAX. Assuming these are all round-trip passengers, and based on Kayak etc prices of such tickets running around $150 all-in, that is $555 million in direct revenue generated from this traffic. If this rail bondoggle costs $77 billion (and I'm sure that's a lowball estimate) and assuming ALL 3.7 million passengers use the rail vs air, it would take 139 years for this thing to break even....and that is excluding interest costs.
To use a Yiddish/New York phrase, oy vey!
Excellent stat. I love it. Thanks.
