I am actually wanting to see this operational one day, it sure make trains and planes very prehistoric. Why do I want to see this in the future? Well I've always wanted to go to Japan but i have a problem on how long you may have to wait 13-15 hours(of course depending were your from) this would actually very convenient.

What do you guys think? Would you ever ride it or maybe your too claustrophobic? Would it be more affordable than booking a plane?
Just cause I like the concept, I would be brave enough give it a try, well once its save but what is safe these days....

it sounds really good. i didn't hear anything about ticket prices, it could make international travel much more practical

I've seen faster and it might be impossible to believe but it has already been proven a long time ago before a modern transportation came to be.

Thats too funny.
