trains
i just wish there WAS a train here, i have to drive 109 miles every day, id gladly take an old steam train if it meant i didnt need to drive as much.
sure trains go through town all the time...carrying grain, or semi trailers, or livestock...no people.
as for this train, sounds nice but ocean pressures already pose the risk of implosion, increase the pressure differential and you increase the risk. add to that the need to keep this tube air-tight at all times (hence why they dont wanna go places that get hot and/or freeze bad on rubber o-rings) and the process of constantly pumping out the air (as an aside though subways have similar issues...constantly fighting against encroaching groundwater)
as for getting in and out of the train, probably have an air-lock.
overall kinda nice but a maintenance nightmare
