Well assuming we start moving forward with the Relief Line, I'm interested in discussing the profound impact this will likely have on streetcar routing. Below are my thoughts.
501 and 504
* Note: a "/" indicates that the station or street depends on the alignment chosen.
A full Relief Line-U eliminates the need for the 504 between Dundas West and Sunnyside, and the 501 or 504 between Sunnyside and the Don. If we assume the Relief Line terminates at the University Line, based on studies to date, I would expect the 504 to become a service between Dundas West and St Andrew/Osgoode. The 501 could develop a new branch to serve Broadview, but should still terminate at Neville Park loop.
For a Queen alignment scenario, the 501 could run on King between Sunnyside and the Don. The 504 could turn from Roncesvalles to Queen and terminate at Osgoode.
514
What happens to the 514 if a King alignment is chosen? Perhaps it could become the new route running from Broadview station, down Broadview and King, to the Distillery District?
502 and 503
Will these need to be separate routes? Can they just be folded into one, terminating at the first Relief Line station on Queen?
505
The odds look good to me for a station to be at Gerrard and Carlaw. In this case, I believe it makes the 505 a bit redundant between Main Street and Gerrard @ Carlaw. I can see it terminating at this new Relief Line station, but would it continue east to Main Street?
Well, 502 and 503 should probably be folded into one today; not even waiting for DRL.
Overall, I would try to run streetcar service on all major downtown streetcar lines that have service today. Obviously, the frequencies would be reduced on the routes competing with DRL, and the route structure may be changed so that some routes feed DRL rather than go directly into downtown.
Reasons to retain all major lines:
- DRL stop spacing will be much wider than on the YUS loop, hence a granular local service will be needed.
- When a scheduled or unscheduled subway service interuption occurs, it will be easier to substitute with large streetcars TTC is currently buying than with much smaller buses.
- The potential operational savings from providing the local service using buses instead of streecars will be small on the overall scale of TTC, since the length of affected routes is small.
Yet, some savings can be achieved from:
- Reducing the frequency of streecar service where it competes with DRL, and
- Taking out of service and eventually removing some of the connecting tracks, such as on Richmond, Adelaide, Bay, McCaul, Victoria etc. Currently, those tracks are maintained mostly for operational reliability. With DRL in place, TTC can afford a bit more operational risks in the streetcar system, and hence some of the redundant non-revenue track can be retired.
