I am curious how the routing will work, when QQ East has the tracks but the Union loop retains the old (low) capacity.
1. The existing tracks are in the tunnel at the QQ & Bay intersection. Presumably, the QQ East tracks will need to descend to the same level, and a Y-shaped connection built. The streetcars will be able to pass in any direction.
2. Technically, can keep the 509 and 510 using the Union loop, and direct any new QQ East routes to QQ West. But that would create some issues. First of all, much more service on QQ West than on QQ East, while the demand level is comparable, or perhaps higher in the east. Furthermore, riders who use QQ East will complain that those lucky souls on QQ West get 2 routes straight to Union, while QQ East gets none.
3. Another option is to reshuffle the routes, and give both QQ West and QQ East 1 route straight to Union. For example:
- 509 Exhibition still goes to Union.
- 510 Spadina, all cars turn back at the Lower Spadina loop.
- One new route from the east goes to Union.
- Another new route serves both QQ East and QQ West, and runs straight through the QQ & Bay intersection.
That's a more even service distribution, although comes with a risk of another kind. The two routes running straight to Union will be insanely popular and always crowded, with no chance to boost the frequencies because of the loop size constraint. Meanwhile the run-through route might have the slots to add service, but won't get enough riders because it doesn't go where the majority of riders want to go.
There were many options how an e-w line would work with the network.
The existing tracks in the tunnel has to be lower and will effect the T connection that will have to be lower as well including the portals.
Since there will be 4 platforms at Union, 509, 510 and 5xx will have one for themselves with a spare that could be use to drop off riders before moving to a platform. When another line is added, that spare would be use for it. Depending on quality of service, you could have 2 lines using the same platform
End of the day, quality of service and ridership will say which route goes to Union and bypass it. I see both happening as you are servicing different market and needs.
What is not on the table at this time is service from Humber Shores since no real line exist today as well the Lake Shore line is on the backburner as well the Dufferin Connect to the Ex. When those connection open up, it opens the door to an number of option and it will be at least 20+ years down the road. The EA was approved back in 2010 for Lake Shore Redevelopment that moves the road north with an ROW in the middle..
You also have East Harbour by a new Broadview extension to Commissioner that will come into play as well.
If the Lake Shore E line was added back into the master plan as first approved by TTC Commissioners as well council it would offer more options. It was removed from the approved master plan when the province requested that the master plan to be broken into 3 sections by TTC staff unknown to to the team in 2006.
1: Line from Broadview to the Portland
2: Line from Broadview to Union
3: Line from Broadview to the EX for special events
4: Queen/Kingston Rd would do 1-3 as well
5: An e-w line that would bypass Union to the Ex from the Portland
6: A Portland to Union
7: Commissioner Line to Union
8: Commissioner Line to the Ex
At the end of the full build out of the Portland and Waterfront, Union will be useless as it will not handle the number of vehicles to service the needs system wide and something I have said from day one when I first saw the plans for Union. TTC is only seeing 8-10,000 from the east while I see 15,000+. The longer it takes to build this thing, more cars will be on the road because it so late now.
