Posted by steamdriven on Fri Jan 23 00:28:41 2015, in response to Re: AirTrain Proposed To Connect (7) Line With LaGuardia Airport ($450 Million, 5 years), posted by Stephen Bauman on Thu Jan 22 22:28:55 2015. Flood problem options:w) Provide trains with flippers. z) Provide passengers with flippers, and snorkels if generous /s There does not seem to be a good solution, as the train needs to get well below the airplane flight path. Within the airport, doesn't it need to be underground, or is there some routing allowing it to be elevated? I'm not familiar with this detail. Obviously its better from the transit perspective if the entire line is above the occasional flood, but perhaps that can be mitigated: Flood mitigation, amateur hour ideas: --Make tunnels water-resistant, make most/all equipment within rated for 24 hours immersion in brackish water. -- Enclose/elevate all tunnel portals, vents, etc so that flooding is indirect, from leakage, rather than from direct flooding. ---Install air powered pumps like IRT has, those keep working regardless of nearby electrical issues. // all of the above to be replaced by real engineering, I'm just making the point that just as tunnels run under rivers, they can run under flood zones. Flood mitigation, essential item: Fire anyone who shows signs of idiocy or laziness, else one has WMATA syndrome. e.g., MBTA had a flood in which they "forgot" to close the flood doors built into one tunnel portal. Feds bailed them out 100%+, paying overtime. Floods may still cause surface rust on the rails, but that can be fixed rapidly. I do not concur with building a train to nowhere aka end of the 7 line. A 10 mile ground trip should not take longer than a 1000 mile flight. In this case, building nothing is better than using good labor, materials and revenue to pursue a defective plan. |
