You're 'objective reasoning' leaves a lot to be desired.Even VIA rail has attendants at the bottom of all their escalators to prevent people from being trampled.
Persons with disabilities or tired and weary after a long trek would need even more than that at the bottom of a difficult set of stairs. "Ah, but there's the elevators" some might respond. Sure are, for escalator users too.
Why would Metrolinx and others, quite a few who are considerably more 'leading edge' than Metrolinx, still not only use escalators, but use them profusely?
The alternative in many modern stations isn't stairs, albeit logic alone dictates their being available, but elevators are returning in great numbers. Even Onion is using them, albeit like all on the TTC, Metrolinx and Onion, they're as slow as a turtle stuck in molasses...on a good day.
The point remains: There's something very wrong about the stairs to platforms provided within the glass cowls on the York Concourse.
They are of a configuration I haven't seen elsewhere on Metrolinx or the TTC. Or anywhere for that matter other than emergency exits.
And to think that somehow they're safer than an in-line escalator (which also isn't perfectly safe) is fantasy.
I've just searched yet again for this 'Metrolinx policy against escalators'. I can't find it. Anyone have a link or written reference?
