30-34K ppdph is not low capacity, at some point too if the issue is with Yonge we will need to bite the bullet and expand Yonge, a lot can be done to improve capacity on that line, it’s laughable we don’t even have trains that use the full platform yet and people talk about the Yonge Line like it is up against a brick wall with no room to grow capacity.
Ok so you think than an extension to Sheppard will leave to the line being overcapacity, I really still don’t think that’s the case. A lot of these riders are not going to be new they are going to be diverted, so if you do soak up a ton of riders well then Yonge can like also take more especially if we actually fully build it out. We still don’t even use exclusively longitudinal seating because apparently people don’t like it and yet we are talking about the Yonge Line like it has no place to go capacity wise.
Because there’s a lot of talk including in here still (you can see in some of the other posts) that seems to suggest you can hit 30,000+ ppdph without TR sized trains, which simply isn’t the case.
Lets just short circuit this nitpick discussion over the particular capacities of the various lines.
What logical reason is there to oppose adding additional capacity to the Ontario Line? Worst case scenario, you've "wasted" a billion dollars ensuring smoother operations of the Ontario Line for decades to come (a line that is 70% will run well; a line that's 90% full will have tons of operational issues). Meanwhile, worst case scenario with an under built Ontario Line is that in the not too distant future, we'll need to spend tens of billions more on further measures to relieve Yonge Line crowding.
The risk factors far favour just building the thing with proper capacity from Day 1.
