I'll add that
- that Airport spur has been given no context beyond it's inclusion on that map, and appears to approach the airport from the wrong end to serve anything but the middle of a runway; and
- Cambridge GO by way of Milton is officially not the preferred option. Stage 2 of the Dillon / RoW / Metrolinx study firmly committed to using Fergus.
My perspective would be that reserving a ROW for some kind of airport link might not be a bad idea, but well into the foreseeable long term the airport would be more than properly served by a high quality bus service on Fountain Street. Once ION is in place, redirecting iXpress 206 up Fountain to the Kossuth / Fairway roundabout then west to Fairway Station would be a really good support for an already designated greenfield area. With an expansion of the on demand area down to roundabout this really would be plenty short term.
Longer (more like medium) term extending the 206 direct to the airport then onto Breslau GO , with a new Airport iXpress from Fairway, ideally extending on to Guelph, would make a lot more sense than a strange heavy rail spur.
What I believe is going to eventually happen is that the feds are going to end up funding a large portion of its cost, like how the feds are paying for half of the Hamilton LRT. However, I don’t believe that these discussions will happen until Cambridge shows interest in and signs a Housing Accelerator Fund agreement to end exclusionary zoning.
I like the suggestion, and do think that Federal money is reasonably inevitable, but how familiar with the Cambridge zoning by-law are you? It's already got universal triplexes (not that Bill 23 left much choice)... How much less exclusionary do you picture the feds demanding? Fourplexes everywhere? No control on built form?
From the direction I've taken on the last couple posts I don't think anyone will be terribly surprised that I more or less support letting Waterloo Region grow into Guelph. Frankly, it's not necessarily IDEAL, but as far as giant patches of green field go its a lot less offensive than most other places it could go (like, say, along the 413 corridor). Moreover though, I think it's inevitable whether one thinks it SHOULD happen, and given that we'd be a lot better off ensuring this is built as a reasonably sustainable actual expansion of the urban area(s) rather than a patchy exurban mess of sprawl.
PS: I didn't address the RoW's take on stage 3 Ion (being that King / University / Erb / Ira Needles / Victoria thing). I like the Waterloo part, but really think that there SHOULD be that crosstown rail service rather than full xRT (an even more tram like LRT might be worth consideration, but I really have a hard time picturing this actually being built as anything but BRT) on Victoria. I'd most likely suggest stage 3 ending at the Boardwalk (and ideally an associated GO station), and taking Stage 4 west on Highland, south on Fisher-Hallman and East to Block Line station with consideration for continuing on to Conestoga College via Manitou and Homer Watson.
PPS: I also didn't mention the
other big project I have in mind for the area. I wholeheartedly agree that Fergus is far better than extending the Milton Line to Cambridge, but am quite fond of idea of extending it up the Guelph Junction Railway with a station in Campbellville. I could be convinced either way as to whether that station should be before or after the junction with GJR, but at a glance the idea of passenger trains through Waterdown to Hamilton is attractive enough it seems slightly preferable to put a station in a position it could serve such a branch as well.
