My random thoughts on all this good conversation. Frances TGV and Japans shinkansen probably have a leg up on us yanks due to a new way of thinking. Putting money down up front to create a national network that can run from city center to city center, combined with zero defect operating plans. Aerodynamic trains is another of those old ideas someone mentioned. It's like a long airplane without wings. To reiterate some other folks comments about airtravel. I'm in Denver. Our airport is a 30-45 minute drive from my house depending on traffic. With security walk through taking up to an hour and the added half hour of sitting and waiting. Travel time including taxiing to the runway and back. Then waiting for luggage and such. What a waste. I have inlaws in KC and the bi-annual drive to visit takes ten hours doing about 70 MPH. What I would give to be able to go downtown and hop a bullet train at 7 am. The train would pull out of Union station and amble out of town at reduced rates till it can hit the eastbound mainline for Kansas City. Once we clear all the junctions and curves our engineer cranks it up to nearly 200 MPH for the four hour train ride into downtown KC. I could hop off the train in Kansas cities enourmous passenger station. My inlaws would greet us with their car. By 1pm I'd be sitting in a Kansas City barbacue joint, maybe Gates or Bryants, devouring some ribs and licking sauce off my fingers. I can dream can't I? One question for those in the know. How much is the individual cost difference between air travel and train travel on bullet trains?
