Tell me you never been in New York City, New Jersey (PATH), Chicago, or the Paris RER without telling me you've never ...
I have been on the NYC Subway and Paris Metro and RER. From my experience, NYC is dirtier, Paris is cleaner than Toronto. But why are we punching down instead of looking up? Let me be or exact, East Asia + Singapore is the gold standard. New Middle Eastern metros as well, which are technically West Asia.
Generally speaking, North American subways are dirty even compared to Europe. Including Warsaw Pact, and post-Soviet Europe.
Tell me you've never ridden buses in Bangkok without telling me you haven't rode buses in Bangkok - a clean subway station is lost if the connecting bus is so poor, and crush-loaded to an extent never seen in Canada.
You're sounding almost jingoistic again.... Lost as in not visible or not appreciated? Or lost as in becomes dirty? Bangkok's rail transit is better than Toronto's by absolute measures (kilometres), but relative to population in a similar area, Toronto's is better last time I checked, barely. Transit expansion is much faster there, it might've already caught up or exceeded Toronto.
Anecdotally, this Bangkok MRT station looks worse than the TTC? They also have much lower ridership per km than Toronto, so I highly doubt any claims of overcrowding.
Wait for Lawrence East station. An early design only had (lots of) express elevators; but I think they value-engineered that into 4 or 5 escalators to get out.
Speaking of which, an objective weakness of Line 5 Eglinton is the lack of redundancy for less-mobile folks. There is only one elevator to platform level from concourse, often only one elevator from surface to concourse. Most stations have one escalator for each direction to and from the platform. Deep bore tunnelling (which often cannot be avoided) is not the problem.
The problem is I have seen the same 5-6 elevators be down intermittently since the first two weeks of opening. With no back up. I guess if you're a wheelchair user, you are SOL.
