Ah, interesting! A couple points: How would you have gotten the line from a King St tunnel onto the Don Branch? I'm genuinely interesting in ideas about that possible connection, because it does seem quite complicated (but worthy of being analyzed). Generally I'm not a fan of any 'direct to Union' routing. If this is to be a pseudo-DRL, I think it's worth it to combine the project with a tunnel through downtown.
I'd love to discuss that with you, but I'm worried the troll would come out and bite us. But seriously I am no expert, I jut think there must be room there particularly if Bayview Extension were closed during construction, or even permanently. It's not a very useful road.
Another thing is I believe you're overestimating the complexity of twining/refitting the Half Mile Bridge. Metrolinx did a similar bridge widening project over the Humber for the UPX/Georgetown corridor. Literally, the bridge is almost identical in design, but slightly shorter in length. There are 1986 estimates for refitting the Half Mile, and the costs don't seem all that high (particularly when compared to the astronomically-priced subway projects we've undertaken since).
Good point. For fun, I did some digging, and Half Mile is twice as long and about half-again as high as the Humber Viaduct. Having (*shhhh*) walked it myself, I just assumed the abutments would have to be replaced entirely. But the Half Mile's concrete abutments date to 1920, and the Humber's date to 1911, so quite possibly I am wrong. (BTW what a beautiful structure, it would be nice to preserve it.)
The tunnel idea is interesting. I would not be opposed to merging DRL and Don Branch. It may not provide as much relief as, say, Coxwell, serving a larger area of southeastern Toronto, but would be substantially cheaper. Some people, like Steve Munro, would probably object to this though.
Anywhere east of the Don could relieve Bloor-Yonge, as long as it offered attractive connections. You are comparing to the Spadina interchange - but nobody uses that on the grounds that St George is much more convenient. I worry that your long escalator would have the same effect - most people would stay on until Yonge, and put up with the crowds cause it was fast and easy. A tunneled line otoh could start in Riverdale Park somewhere, tunnel under the Adult Learning Centre, and terminate nicely in a new station right under Broadview B-D station. (Uh oh, I might have awakened the troll.)
I don't think UPX would ever shut down, as it's expected to be a profitable service for Metrolinx, so currently we're stuck with it wasting corridor passenger capacity that could have been used for bigger-capacity rapid transit trains (larger subway sized or GOtrain sized trains). There are reasons why it's going to be hugely popular with airport travellers, even to the point of occasional standees on 3-car trains (747/A380 landings). So if routing to Union, then another train berth will be needed (even Platform 3, if it's not a through route), or Don Branch could perhaps behave as the East-side continuation of either Kitchener or Barrie RER trains (perhaps Barrie, since Kitchener line will be paired up with the Stoufville line, in the SmartTrack plan)
My view on the profitability of UPE are different, and they are stated a bit upthread of yours, so I won't rehash it. But however popular it is in its current form it would be WAY MORE POPULAR if it only cost 3 bucks - and offered a connection onward at Broadview to boot. (And even if it was slower because of the addition of a half dozen local stops.)
