Where there is enough population density and 'right of way' for trains, trains almost always make sense. Flying is better for NYC -> Colorado - LA but trains are better for NY -> DC corridor, and frankly, probably all the way down to Florida. There is the issue of 'downtown' and 'walkable cities'. If you arrive in Baltimore near an airport, you have to rent a car. In European cities, you hop on the Subway to the Hotel, that makes a big difference as well. But Boston->DC is ripe for train transformation. And 'established circuits' SF->LA->Vegas should be high speed - that California can't sort that out is really sad, it's a matter of organizational/systematic incompetence. There needs to be kind of a 'civic buy in' for it to work
