They've used that long Parliament/Dundas/Broadview loop for scheduled detours and it was a disaster. At rush hour you would have five cars out of service looping around there for 10 minutes in traffic. Parliament connects multiple routes, and I pointed out there's an opportunity to build a new loop in a spot that's in proximity to several of them with curves in place to facilitate it's function at the adjacent intersections. On a scale of streetcar fantasy proposals, that's far over on the reality side compared to many. But, really, this was only a simple respose to the coversation about the Broadview loop no longer being available to build and the discussion about possible alternatives.Of course, one can put a loop anywhere one wants but why would you put one here? OK it's empty but you need to look at alternatives that will actually provide useful service benefits or transfer points. The TTC can already loop from eastbound King or westbound from Queen via Parliament/Dundas/Broadview or use Distillery Loop and the loop they have (had?) planned for on Broadview just north of Queen plus the loop that will need to exist at south end of Broadview if/when THAT extension is built. Surely better to increase possible curves at appropriate places all over the network to allow for more flexibility. (At one time there was talk of creating a loop at the west side of the Don River bridge on King/Queen that would allow moves between King and Queen and this could be connected to Dundas by adding track on River between King & Queen. Frankly, the possibilities are many but the need is really not there. Building loops is not cost-free and it is probably far better to use scarce $$ to add curves or, for example, add alternatives like fixing track on Adelaide or even extending track on Richmond to Spadina. Adding a new loop on Parliament or almost anywhere is really a subject for the fantasy thread!
