That makes sense on those tradeoffs, I'm just wondering how many people would use high speed rail by going to a station and waiting for it. Maybe if they could make the departure and arrival seamless. And also have frequent departure times it could work. I used to take the train a lot from New Jersey to NYC and the 1 hour gap made it kind of a PITA, 15 minute increments makes it so one doesn't have to plan so much around it, and it is thus more likely one can rely on it.
