ahhhh i see its the osgoode hall thing again, LOVE IT
No you don't.
There is a big difference between "OK" and "GOOD"
This is true.
Look at king station on the Yonge line, its already over capacity, those stairwells absolutely do not work, they are very cramped and during rush hour hard to get through.
'already'? It was built in the early 1950s, so its capacity was mostly sufficient for 70 odd years. Psst, King Station is getting expanded, the concourse level will begin to grow in 2 years. I expect some additional vertical circulation as well, but I haven't seen the detail plans so can't attest to that.
People talk about the trains of the ontario line and how they arent the highest capacity, I point out that trains arent the only thing that makes capacity differences.
The stations themselves also contribute to capacity, large platforms, big entrances, multiple separate escalators/stairwells
Why should we be okay with limiting capacity?
This argument would cut both ways.......but I digress........
I believe Osgoode as currently designed will have congestion issues; that's a point of conjecture I suppose, as those designing the station feel there is adequate space in their models; I think there are problematic pinch points, and they've been overly conservative in their assumptions as they apply to the existing Line 1 station, which their mandate suggests they are not to address more than necessary....
That said, I would agree w/you that
@T3G 's idea, taken on its own (without other changes to the design would not be sufficient. But there's nothing wrong w/the idea per se, is merely a matter of how one would otherwise address capacity constraints.
Regrettably, I think the choices made here impose substantial constraints and additional costs, in respect of future capacity expansion.
Leaving the existing Line 1 Station non-compliant with the Fire Code (no second completely independent exit from the platform) is a serious problem to me; and I'm not entirely convinced its consistent with the law.
I believe vertical circulation capacity between Line 1 and the O/L is also inadequate.
I think these issues would have been better addressed with a completely different set of design choices. But both Mx and the City dropped the ball there........sigh.

Edit, I should add, the large impact on Osgoode has as much or more to do w/the keyhole access (extraction shaft for the TBM) than the entrance itself. This too could have been avoided by doing the entire stretch from University to Yonge as cut and cover, including the intersection of Univ/Queen and extracting the TBM within the ROW of Queen.
