Actually, the U.S. - outside of government/politics - is largely fueled by practicality, not unneeded, overpriced crap that only stands to benefit a few, especially when a 3 hour plane ride can replace an 18 hour train trip. If you are so convinced HSR fills a "social need" in America, would you care to put your money where your mouth is and pitch in?
Listen, I know you're a railfan. So am I, big time. So is pretty much everyone on this board. But let's not let this cloud our judgment.
I'm not convinced at all that there is a need for HSR rail in the US.
But also, emissions play a huge part in the need for hi hi speed rail. And there again, the US falls flat on its face.
Its cost more to have transport that produces less emissions.
So why would any US citizen pay more to use a train that produces less world pollution and takes longer. When they can pay less, get there quicker, for less and produce even more pollution.
