That doesn't logically follow. Planes are flexible, you need the airports at both locations, and aircraft to service the route, but if the route doesn't fill all the planes scheduled for it, they airlines will shift them to other routes. You can shift trains as well. In addition, trains will pull people out of their cars. There is a sizable number of people who refuse to fly and drive when they have to go someplace. Those people can be prime train travelers. Rail doesn't just need the stations and rolling stock, you have to specifically lay out all the rail between the two locations. If a route doesn't get as much use as expected the passenger miles per dollar invested in setting up that route go down. You can pre-determine ridership based on densities and freeway driving. And trains don't got in a straight line.....if they did, they would save more time. Instead, they will hit the medium size cities along the way. For an example, a train going from Chicago to St. Louis might stop in Bloomington, Champaign Urbana and Springfield:Also aircraft are faster, even with time for security checkpoints the trip takes less for many of the longer routes (while on the shorter routes trains compete with cars). Not when a traveler is going from downtown to downtown. Often times travel times are very similar. It might makes sense for some routes. The north east corridor (if it would actually be high speed rail, rather than "just slightly faster rail) in particular, maybe connecting CA's larger cities. But for most locations it doesn't make sense with our population density and existing interstate highway system. (China not only has higher population density, and a clustering of its large cities that fits rail travel better, it also has a lot less highway and air infrastructure and equipment per person.) The plan isn't for Fargo to Rapid City, but it does have a a Cleveland-Columbus-Cincinnati-Indianapolis corridor, a connection from Buffalo to Albany, one from New Orleans to Meridian Mississippi to Birmingham to Atlanta (with only the last being a fairly major city). Most of the major HSR lines in Europe are profitable and like I pointed out previously, people preferring training rather than flying on routes similar to the distance between Chicago and St. Louis,
