Anyone think it'd be a good idea for Eglinton West to be a completely separate line from Crosstown? Hear me out. We know the Prov now wants this to be fully grade-separated (ie a "subway"). But since it's connected to the rest of Crosstown the line wouldn't be a subway by default. This could actually be one. Two car trains. Sort of makes sense to do it this way since 1) Crosstown uses hefty low-floor vehicles designed for urban tram use. Not exactly a vehicle befitting of full grade-separation in the suburbs. And 2) Crosstown east of Kennedy is dead, all configurations. So the line is really a shell of its former vision with room to play around. Also full Crosstown stations would be 90m long, this would be half those lengths (less cost).
But there's more. Sauga has done some heavy lifting with Transitway grade-separation between Renforth and Hurontario. This could lead into that (one day), just needs a proper connection to Sq One. Also one day, a N/S subway of the same system running from Kipling to Pearson - this is integral to the vision and the reason I posted. It'd be an integrated network of smaller automated subways serving 427 corridor-East/West Mall, Pearson, Eg West, and Sauga. Be a bent cross shape, about 30km, four services: Sq One-Kipling, Sq One-Black Ck, Kipling-Pearson, Pearson-Black Ck. Drawbacks, yes. But huge benefit.
