This viewpoint assumes that everybody getting on at Yonge is due for a destination south of Bloor. They maybe heading south, but they may not all be heading South of Bloor. There's bound to be riders who would take Sheppard from STC because they are due for points closer to Sheppard (south or north).
Sure, there will be some going to points north of Bloor but if Eglinton has a line why would someone at SCC take Sheppard? Sheppard/Yonge is north of the Sheppard east of Victoria Park and north of SCC. To go north in order to go south reduces the number of people who will take that route.
In any event though, that's not the point of the Sheppard line. It's just a happy byproduct that it feeds Yonge. But that's not its main purpose. It's supposed to be a Cross-town.
Real bad choice for a cross-town. A subway doesn't cross town quickly compared to commuter rail, Sheppard ends at Weston Road and has Downsview Park in the middle of it, and it is very unlikely that as a subway it would ever "cross town" to take passengers from Pickering to Mississauga. Due to that it will never be able to take much share of the 401 cross town traffic. GO ALRT was a cross town. Sheppard Subway is a local service that is overbuilt.
For example, how many York U students do you think would take the line if it ran from STC to Downsview? I am willing to bet 10k riders just from York U students in Scarborough per day at least.
None of the residents and none of the students that live outside eastern North York and Scarborough. Lets assume that 20% of the students at York actually do live in eastern North York and Scarborough, that billion dollar extension brings in the ridership of the Morningside bus route. I don't think that it will push the ridership into the territory where having a subway was required.
How many UTSC and Centennial college students in North York and Etobicoke would suddenly find their campuses significantly more accessible by transit if they didn't have to trundle down to Bloor or Eglinton to get across town?
Those college students need an education if they think taking the subway to Bloor or Eglinton to get to Scarborough makes sense. York Mills GO to Scarborough GO and the 38 bus. GO gets you from Yonge to Scarborough Centre in 16 minutes and the subway isn't really going to do it any faster. In fact the GO plus Transit City's connections to UTSC and Centennial College would get you there faster than Sheppard built without the LRT extension past Centennial and the Malvern Line spur which had a chance of being build for the Pan Am Games. Even taking the 95 bus is faster than going to Bloor.
That was the TTC's contention. Not mine. They also assumed that a subway would only draw in an extra 1000 or so riders per hour. I find that particularly hard to believe. I'd love to see their assumptions and raw calculations on that one. Makes me wonder if any of the guys who worked that out have taken the Finch bus during rush hour.
So which is it? Would the SELRT adequately handle the ridership on Sheppard or not? If the answer is that it cannot handle passenger demand then it doesn't rule out the possibility of building a subway or at very least grade separating the LRT at bottlenecks to increase carrying capacity. Only if the SELRT can easily accommodate the ridership would it render a Sheppard Subway obsolete.
Really? Is that why Metrolinx had proposed that Finch continue on Finch East till Don Mills and then head south to Don Mills station before heading east on Sheppard? They wanted to avoid duplication?
Transit City wasn't planned by Metrolinx and despite Metrolinx wanting a single line across the city it wasn't a priority to the city which felt the section between Yonge and Don Mills was already served by the Sheppard Subway.
They picked their grid with zero regard to where ridership is today. That much is clear, looking at which bus routes would be replaced.
So Eglinton, Finch West, and Sheppard are not where the ridership is? If that isn't where the ridership is then how can we possibly entertain subways which would serve the same purpose?
Not just that. They also picked routes without much thought as to how the corridors would develop. For all their fantasies about pedestrian-friendly streets, apparently none of these planners drove past Markham on Sheppard and saw the great backyards of Malvern which are available for re-zoning.
It is a continuous route. The options would be greater segmentation of the route, or a continuous route. I don't think they expected that the parts of Sheppard east of Markham would redevelop that quickly. The backyards of Malvern don't rule out redevelopment though... the NY Towers development at Bayview was all residential.
But avoiding building between Don Mills and Yonge is clearly wrong.
There is a subway there. Hopefully it can handle the load.
Even more galling was the fact that they didn't plan a spur for STC. Skipped right by it. Apparently the zoo was a bigger priority.
They didn't build a spur into the zoo either. Spurs to STC, UTSC, and the zoo were contemplated for the future.
