But at this depth, there are lots of people who can't make it up and would be stranded. If summer, the heat could kill them. It's not the joke you imply it is. Though I'd guess that MTA Construction considers it a joke.photobug56 wrote: ↑Thu Aug 05, 2021 4:11 pm but you also need emergency power for escalatorsYou do know what escalators become when they're not powered, don't you?

It could be a real problem for EMS people to get a stretcher halfway down and then back up with somebody on it.photobug56 wrote: ↑Thu Aug 05, 2021 4:11 pm but you also need emergency power for escalatorsYou do know what escalators become when they're not powered, don't you?

And there would have been issues; would you use consists with dual upper lower third rail shoes, for instance. But experts in the field felt it was doable, and at much lower cost. Regardless, much of the cost of ESA is related to, supposedly, incompetence, lack of supervision, nepotism, massive numbers of workers without actual work to do, excessive tool spec requirements and the like.You're not far off the mark; certainly, the costs on projects in NY are much higher. I also think they grossly underestimated the complexity of the project.
