"They can go beyond STC if there's something worth going to - and the Zoo is not worth two lines."
That's the basis of the loop. The Zoo wouldn't be a route's end, rather just another station along a continuous line. If we can have subways ending in Downsview Park and not-close but close enough railyards and ROWs (Kipling and Kennedy), what's to stop an elevated line from working in northeast Scarbourough? I haven't closed off my mind from an extension beyond the Malvern area either.
"Malls are probably the #1 trip generators, and their parking lots are great for park'n'ride commuters and/or can easily be converted to towers."
Yes they are, but within reason. You're talking 5 kms of unused subways to reach Hwy 7 when there's already a GO station there. Where's the logic? The undeveloped lands around Malvern Town Centre (yes it's a mall) and Sheppard-Markham intersection can produce just as many kiss'n'ride spots and there'd still be room left over for regional BRT terminal to Markville.
"Two S-curves in such a confined space (between John and Bathurst) may not even be possible."
It is if the curve starts at Peter St, line runs diagonally to Alexandra Park (near Bathurst/Dundas) and veers down Bathurst. The train comes to a complete stop, (Wollesley Loop site is where the Bathurst stop would be)
before turning back onto Queen St. No screech, enough spacing.
"Two lines to the Zoo is the brilliant idea?"
I was referring to my proposal to utilize the inter-Toronto GO stations before expanding the subway system. If fares were made compatible with TTC fares and there was a guranteed all day service, more people in Toronto would use it. There also more things that could be done such as aquisition of some of CN tracks like the one that runs through central Toronto (already passing by Dupont and Summerhill Stns) which intersects with every north-south bus route in the northeast. Unlike your plan for the NW, this already exists and if started today would likely be operational by the end of the decade.
"Yeah, you've covered the corners, but what about the middle? Thorncliffe Park, Jane & Finch, Don Mills & Finch, Bathurst & Steeles...major nodes, with tens of thousands of people, but they get no lovin'."
Okay here's one. Since you despise jogs so much lets have the Sheppard Line dip upto Jane-Finch and back, upto Bathurst-Steeles and back, upto Seneca and back and have the Eglinton Line dip down to Throncliffe Park and back. Bathurst-Steeles would only work if YUS avoided Vaughan and loop back to Yonge- which was an outdated suggestion from the '80s.
"Complete Sheppard, Eglinton, Queen, Front, Weston, and Don Mills lines would create an incredibly powerful network of subways."
Nice you prioritize my east-west lines first
! Come to think of it a 'Front' downtown-bypass line may work. It's still apart of the Queen Line only it separates from the line at Dufferin and Broadview with stops at Exhibition, Strachan, Fort York (this also would comprise a people-mover to the Island Airport), Skydome, Union (why not construct this concurrently with the new reno), St Lawrence Market and Distillery. This would run during rush-hour peak and holiday/special events.
"Subways should go where demand warrants, not to far-flung corners of the map where riders are few and far between... building full-fledged subways anywhere but the high density neighbourhoods that can support them is a waste of time."
But in order to get to those 'far-flung corners' the lines must and DO pass through dense neighbourhoods. I'm for inclusion not exclusion of people who can't afford to live in the core but must get to work/school/amenities somehow.
