not that i disagree with you, but i think it's even less likely they convert Line 4 to light metro or light rail. i've heard in the past that it would be > than a billion just to do so.
that's why it probably makes more sense to just combine/loop Line 4 with Line 2. that way this is never a discussion in the future to push for either line to go further North or East when it makes no sense financially to do so.
If the trains are the same there'd be no cost to convert.
Not sure if using shorter trains made of wide TTC subway cars will save a lot of money. But if it will, then I'd go with the current 4-car trains.
Two cars / 12k pphp is probably too little for the central segment. It may be below 5.5k pphp today, but as the length of the subway increases, there will be more reasons to switch to the subway from the parallel routes. I think 12k or even 15k pphp can be achieved on the sufficiently long Sheppard line.
Our trains are wide. But interestingly they have a significantly smaller profile than those proposed for the Ontario Line. And 12k pphpd is a lot of capacity and effectively future-proofed.
