Re: Non-reversible escalators?

About 3 years ago, the NY Times ran an article about the problematic escalators from 7th Avenue west sidewalk into NYP. (They specifically mentioned that the escalators were installed in 1965, without mentioning any reason why new escalators were needed then. We sadly know why...)

They went on to say that the escalators, while built with reverse capability, had rarely or never actually been reversed in 50 years, and that the various mechanical parts had by now been worn and stressed in such a way that reversing them now could cause them to seize up within an hour. Personally, I don't have enough knowledge of metalworking or mechanics to call truth or BS on this, but it does seem at least consistent about what they say about "breaking in" a new car

The article ended by stating that someone (I can't remember of it was Amtrak, LIRR, or MSG) had committed to overhauling- but specifically not replacing, the two escalators.
