Considering the time scale we’re talking about, a network we design now might have to change quite a bit before we build the last of it. No sense building a line to Detroit fifty years from now if it’s a ghost town by then. That’s one argument against the whole thing, by the way. Europeans are much less likely than Americans to up and move to a new city. (At least Germans are, I’ve read that somewhere.) I was in Nuremberg for a few months, which was the place to be in the 15th and 16th centuries and is still the largest city in Franconia. The cities, and people, aren’t going anywhere, so it’s probably easier to justify an expensive, fixed-route infrastructure.
The idea is that it lets each group do what it does best. The government establishes the standards, and takes on the capital construction of infrastructure that should last for many decades and may never directly recover its costs. The private operators compete to serve the public, doing research and adapting to the market, and advertising themselves.
Paris and Moscow are connected by rail lines. (I remember looking at a night train schedule and thinking “train gets in to Moscow at noon, that’s not bad.” Then I noticed it was noon the following day.) I don’t know if many people take that trip, but it can be done.
I don’t think many people would take a high-speed train across the U.S. But if we build regional systems in the places where it makes sense to do so, maybe someday we’ll be able to.
This is just the subsidy argument again. From the price you quoted for an airline ticket, after paying for the fuel, the airplane, the pilots, the flight attendants, the baggage handlers and the ticket agents, how long will it take to earn back the construction costs of the airports and air traffic systems (not to mention their staffing and maintenance costs)?
Not that high-speed rail is an open-and-shut case, but if you’re comparing two systems and only one of them has to account for all of its massive capital expenses, it’ll be no contest.
The only airport I travelled through that was like that was Frankfurt. Just like walking out of the terminal, and up the escalator to the parking garage, you could go down to the train platforms. I wouldn’t call it much of a rail hub, though; in number of trains and connections, it was dwarfed by the central Frankfurt station.
It certainly makes sense to connect air and rail travel, but the hubs should be where the riders are. I see this as a system that should be designed to operate on its own for certain trips, not just a feeder network for the airlines.
