What I find odd about this is that... Trains are the go-to means of intercity transport across much of Europe. The term "High speed rail" isn't strictly defined, but seems to kick in somewhere between 110 and 155 mph. Pretty much every intercity train in the UK is running at 125mph for at least some of their journey. Europe is full of functioning high speed rail networks - TGV, ICE, Eurostar, networks in Spain and It…
I think the author has a very valid point when it comes to the cost of rail tracks. It's something the proponents always conveniently ignore. On top of that, a rail station has quite a limited capacity, especially if it's inside the city. The travel time between, e.g., Berlin and Paris is something like four to five times as long as by plane.
So unless someone develops a low-maintenance, high-capacity fast train, planes with ecofuel are probably going to win any fair competition.
