While i really like shinkansen to replace airplanes in future. However, how is the security on bullet train network comparing to airport (in other countries)? Do they also take the same approximate time as airplane (e.g. 3 hours) to process?
Well i guess in theory, terrorists can't just ride the whole train and crash into the Pentagon like they did with airplanes, so maybe the security won't have to be as tight? But won't it be the same blowing up a plane or a train (in worst case scenario)
PS: on energy problem, i think it should not be a problem, because energy using for trains (move things on smooth surface) will always much lower than for airplanes (levitate and move the same mass). And big power plant will always more energy efficiency that the plane engines.
