The current bridge plates, which just have to go from train height to high-level platform height are heavy enough.And this is all I am thinking of. Take Metropark for example. There is a low-level platform at the north end of the station. So at the extreme end of the high level platform, you install a bridge plate that connects the high-level platform to a high-level door. Non mobility challenged passengers still platform from the low-level platform. The “weekend maintenance” bridges that NJT uses require a crane to set them. Metro North seems to be able to get bridge plates in place pretty quickly on the New Haven line. They set them up all the time for mid-day track work and have them out of the way in time for the PM rush. Of course, I haven't witnessed the actual set-up and take-down of the plates, so I could be wrong. They certainly don't look like they would need a crane to set up -- probably just two reasonably strong people. Obviously that wouldn't work for the temporary service disruption you were thinking about, but I wonder whether or not the design could be modified so that the plate could be easily moved into place by one person. (That's got to be cheaper than installing hydarulics in the trackbed!) CG |
