Regardless of the DRL route there should also be an additional line like as well:
The more and more I think about it, the more it makes sense to de-couple the Yonge and University lines, and send the DRL/University line across Front St, and then up Parliament.
Beyond Castle Frank it can hook up with the Richmond Hill GO Line and then head east to Cosbourne.
A similar scenario at a hypothetical Queen-Yonge interchange would impact the DRL and one leg of the YUS line. If the DRL goes through Union and the same thing happens there, it would impact both legs of the YUS, the DRL, the Spadina and Harbourfront streetcars, every GO line, and maybe even the GO buses. Having multiple hubs spread around downtown ensures that an incident at one of them would have a smaller impact than if there's one massive hub.An incident at Union would force the closure of "upwards of three" subway lines? But an incident at Queen would not? Please elaborate.
Except you completely miss a huge opportunity to address all the major densification being put in place south of Pape (the ex-soap plant corporate campus planned by First Gulf, West Don Lands, Distillery District), you miss the opportunity to have a GO transfer station (at Gerrard or the Queen bridge).
Then, north of Castle Frank, you're stuck. Whereas, north of Pape, you can densify to the DVP at Don Mills and run the line as LRT through to Eglinton, a huge transit opportunity (build out the commercial campus, OSC, the apartments all around the north side of the valley.
Interesting idea, although I don't see why it needs to be linked with de-coupling the Yonge and University lines -- surely it would be cheaper just to route the DRL along Wellington.
The ease of construction at Castle Frank is a nice benefit, as is the shorter length of tunnel. But like Riverdale Rink Rat said, the tradeoff is that you miss the Distillery and the Don Lands, and north of Bloor there's absolutely nothing until you hit Thorncliffe Park.
I'm not sure about the densification argument. St. James Town is already ultra-dense. Cabbagetown is not going to change. Regent Park is already happening. So it's only the southern end of Parliament where much would change, and I think that's going to happen whether or not a subway is built.
Also, despite the density of the Parliament corridor, I don't think a Parliament DRL would have as much of an impact as a more easterly routing, since Parliament is so close to the core that a lot of those people will be walking, biking, or taking streetcars downtown. A more easterly routing would have less competition from these modes. Similarly, a Parliament DRL seems less likely to divert many riders off the streetcar routes coming in from the east, since there'd be little to no time savings in transferring from streetcar to subway that close to the core.
As for having nothing between Bloor and Overlea, the reality is that even a Pape DRL would still only have 1 station between Danforth and Overlea anyway. Building an extra 2km of tunnel, plus a crossing of the Don Valley, is a lot extra for 1 station, isn't it?
Cabbagetown is most certainly going to change. They're already pushing the wall of condos over to Sherbourne St, which isn't that far from Parliament at all. What's to say that it won't be pushed a block further east?
That's a good point.
The fact that there are moves to make it a heritage conservation district? And Parliament too. But yes, in any case, Parliament is still more dense than the equivalent part of Pape.
If we did build a DRL to Castle Frank, what do you think of it then taking over the entire Richmond Hill GO line? (maybe with a couple of strategic diversions)
In the mean time, how about additional frequency and stations in particular the Richmond Hill GO line? I was thinking of the following stations from Union:
UNION all connection
Cherry NEW Waterfront and Cherry Streetcars, DRL
Gerrard NEW 505 and 506 Streetcars
Milwood NEW
Eglinton NEW Eglinton Crosstown LRT
ORIOLE RELOCATED NORTH OF 401 DRL Terminus, Sheppard Subway
Thornhill NEW (at John Street)
Langstaff 407 Transitway
Richmond Hill
19th Ave NEW (at Bayview Ave)
I also know that through-running some Georgetown trains to Richmond Hill has been pitched numerous times before and would be an excellent express compliment to the more local DRL.
According to Steve Munro, it simply isn't technically possible to decouple the YUS line at Union -- there is no room in that extremely crowded space for all the additional trackage required.
Steve: This proposal would involve a complete restructuring of Union Station and the two existing subway lines that, aside from the complexity and its conflict with work now underway, would probably be impossible without a complete shutdown of both lines. Double-decking Union Station would require regrading of the University line (assuming that it would wind up on the bottom level) from St. Andrew Station southwards. The lines could not be completely decoupled because a track link from the now-isolated Yonge line to University would be essential for access to Wilson and Greenwood yards.
Steve: Taking the University line down York Street would be a big challenge because you have to get under the foundations of the railway viaduct. They go down a long way. Also I don’t know how you would build this new connection while maintaining through service on the two lines. As for taking Yonge to the west, yes, if the University line were not in the way, that would work fine. However, you have still not addressed the problem of getting more capacity into the core than the current two lines
Also note that Steve seemed to be working on the assumption that to do so, would involve building a double-decker station at Union - which would interrupt Union Station for a long period of time. You could actually achieve it in other ways, such as stopping Yonge service at the old end of the line just west of Union for years, and instead building new deep platforms for the University line under York instead of under Front, and then extending the Yonge line west on Front, and the University line south on York, and presumably turning east somewhere between the tracks and the lake.For reference, this is what Steve said. http://stevemunro.ca/?p=6218
I'm not sure if he thinks it's impossible, but at the very least he seems to think that it's extremely difficult and not worth the huge disruption that would be involved.

I doubt you'd really want to do this until you've built a DRL though - and ultimately, you'd be looking at 2 additional east-west lines. Maybe in a century or two.
