Posted by WillD on Mon Sep 2 20:36:11 2013, in response to Re: Japanese Maglev train runs at 500 km/h . . . for the umpteenth time, posted by Olog-hai on Mon Sep 2 14:45:06 2013. Most of the cost involved in doing evacuated tube transport is going to be the tunneling. The Chuo Shinkansen is already going to be built with tunnels along some 60% of its length, and will be required to have long segments of covered tracks even when outside the tunnel to disperse tunnel booms. In that case doing ETT over some portion of the route with continuous tunnel or covered external areas likely wouldn't lead to an outrageous cost increase. The airlocks between the ETT and exposed segments would be fairly challenging as they'd likely have to be several miles long and draw a near vacuum in a matter of minutes.Interestingly, the Japanese seem none too enthusiastic about the spartan station design. |
