I can see that mode of transport being popular in Japan. Persons there are used to it and it has become part of its modern culture.Anaxagoras wrote:Well, the Denver International Airport cost shy of $5 billion to build, so let's say that, yes, it would probably cost less to build two new airports (although existing ones would seem to serve the purpose already and where would you put another airport in Tokyo? There are already 2: Haneda and Narita, although Narita is not actually in Tokyo.)
I don't know why. Trains could in theory carry more passengers, but is the demand really there? Plus there is already Shinkansen service between the two cities. A train can also stop at points in between, although that would slow it down.

Last year 143 million passengers rode the Tokaido Shinkansen (between Tokyo and Osaka/Kyoto, with Nagoya in between), and 67 million used Haneda Airport (to and from all the places it serves).
The article in the OP postulates that Americans will take to it and abandon cars, airplanes, etc. Not. Going. To. Happen. The US is a car culture and will not abandon its cars for trains for routine travel in the foreseeable future. This is not a technological issue; it's a cultural one.
