This would be something like my ideal DRL
Where thick dash lines imply an elevated and totally open air structure, thin dash lines imply a cut/cover box tunnel with open air trenches wherever possible and thick lines imply some kind of deep tunnel.
The main difference I suppose would be as follows:
Docklands Bulge: unlike most more northerly alignments, rather than turning off on Queen East or Eastern, my ideal routing would swing through the Portlands on a some kind of elevated structure before heading back up north. Depending on station spacing, this shouldn't really add much time and should save some money on figuring how best to run a subway through Queen East. Given the plans for the area, seems worth serving.
Adelaide alignment: A minute by foot to anything important downtown (i.e. City Hall/Courts, Eaton Center, the financial district) and more or less equidistant between King and Queen. It wouldn't be much good to, say, someone at York and Queen's Quay, but that is the WaterFront LRT's job anyways. It should also be possible to cut/cover along Adelaide (or Richmond), or at the very least much easier than along Queen or King or Front. In my view, this is important. If we have to build Spadina esque uber-bahns under downtown this will simply never happen .The costs will be obscene. Nobody really does much on Adelaide itself, so it should be possible to convince people the short term pain is worth the long term gain.
Spur line: This is an option I'm surprised nobody really mentions. There is no one strait line that will hit everything that should be hit, so why not just make a few tactical spurs to hit them? In this case, it seemed important that CityPlace and Bathurst/Queen'sQuay area have a quick link downtown. It wouldn't have to be very robust given it would only have 2 or three stations over 2km. May even be possible for it to be a single track, with a bypass track at CityPlace. Operationally, It would operate as every third or fourth train from Don Mills peeling south at Spadina.
Light rolling stock: Can't see it on a map, but I don't think this should be the same as the existing subway system. Ideally it would be ICTS but not ICTS. Something on a Madrid or Copenhagen scale.
