So, I'm quite a huge fan of this report. I'm sure with anything there are details to quibble with and numbers to change, but on the whole it seems completely on point. I'm glad civil society has finally (after, what, 3-4 years?) turned a critical eye to Metrolinx/TTC's transit planning process and results.
Specifically,
Finch/Sheppard LRTs: Thank god. These routes never really made sense. The projected speed increases were marginal (18-23km/h) when offset by higher operating headways and wider station spacing and almost entirely the result of practices which,inexplicably, haven't been applied to existing surface routes (e.g. all door boarding, wider stop spacing, TSP and reserved ROWs). Obviously the term BRT is vague (as is LRT..), so I would just call for a major improvement of surface operations throughout the 416 & 905 to reflect best-practices.
Eglinton-Crosstown: Getting rid of Avenue, Chaplain and Laird seem completely logical. Local demand here is nowhere near sufficient to justify stations and redevelopment is unlikely due to strong conservative desires the maintain established neighbourhood form. Laird may see more development, but probably not much. The 61/5 would be better to transfer at Y/Eg anyways, and the 14 could transfer at Bathurst.
As for elevating the portion along Eglinton East, it probably makes sense. Obviously there are caveats around need for more detailed studies, but the basic idea seems sound. The built environment can easily sustain elevated structures and it opens the door to line automation and smaller stations/higher headways elsewhere. When Vancouver was designing the Canada Line, some initial proposals had a similar set up with tunnelled sections through Vancouver and on-street LRT in Richmond. Paradoxically though, since LRT tunnels and stations had to be bigger and LRVs couldn't be automated, building the entire thing as a separated route ended up being cheaper to build and operate than the hybrid LRT/subway.
For LRT-subways to make sense it would seem they need to be highly branched to produce a higher ratio of surfaceROW:segregatedROW. Look at the Porto Metro, for instance. If it's just going to be mostly separated anyways, automated mini-metros operating at high headways are probably most efficient.
Yonge Subway Extension: This proposal actually makes me feel vindicated
since I proposed reducing the route to Steeles and Richmond Hill Station back in October. The other stations see a trivial amount of walk-in ridership (even assuming substantial development) and connecting ridership could just as easily transfer at Steeles, Finch or Richmond Hill. Spending billions of dollars to benefit some developers is stupid and
borderline corrupt. If development makes sense, have the developers build them and have them pass on costs to condo purchasers.
DRL: I'd reluctantly admit that the DRL as currently imagined probably doesn't make sense. Building any line to "relieve" Yonge is a waste of money. To begin with, TTC capacity estimates are conservative in terms of vehicle capacity. Even looking at the TTC's capacity estimates + YSE, vehicle capacity ratios are still only 1.03 or something, which is a very minor capacity gap. Even that only applies to the peak-iest part of the AM peak southbound, and doesn't represent a prolonged capacity gap. Spending billions to address such a minor capacity-gap isn't prudent.
Now, given how much of Toronto's transit market drains onto Yonge south of Bloor, building a line from pretty much anywhere-to-downtown will resolve capacity gaps. We can see this in the DTRES where even building a Lakeshore RT would reduce demand on Yonge sufficiently. My point here being, we shouldn't obsess about Yonge. Minor capacity gaps are a fact of life and as long as we provide new ways to access downtown capacity shortages will be abated. The priority in designing the "DRL" should be serving new transit customers and markets, not on relieving Yonge.
GO electrification: Yes, brilliant.
