I live at Morningside and Lawrence and just recently found out that there is no longer express service from STC to don mills station.

So if I want to go to fairview mall, I have to go to Morningside and Sheppard, and then take the Sheppard bus from Morningside to don mills. That's like 1hr and half without ever seeing a ttc station or go station. No where else in the city can you travel 1hr and half by bus and not come across a station. Scarborough is an afterthought in this city in terms of almost everything
I'm pretty sure the cancellation of the 985A is due to covid...

You will see Agincourt GO station on Sheppard between Midland and Kennedy.

I really don't see the appeal of interlining at Sheppard W. It makes building the interchange far more complex, makes for a worse service for southbound passengers and is a major operational impediment on the Spadina side where frequency is already about as high as feasible. There would have been a lot to be said for building the extension as part of Sheppard, but now it's done, a reverse branch at the north end of the YUS really doesn't seem to have anything that outweighs the operational and construction issues it creates in comparison to just building a quality transfer between two lines that already have very good frequency..

Interlining is worth consideration though I don't think absolutely necessary. But that's a bit different than building whole new tunnels further west.

Rapid transit to Malvern is important but I'm not convinced a Line 2 or Line 4 extension is the most appropriate. I would study these options along with various LRT modes (at-grade or elevated) and routes.

I view the top two priorities for Sheppard as Line 4 extensions to Sheppard West for better network connectivity and to Vic. Park to serve the Consumers Road business area. While I prefer at-grade LRT east of Vic. Park, I'm not against looking at incremental subway extensions to a) Agincourt GO station, and b) McCowan/Line 2 - provided there are comprehensive land use and transportation plans around these MTSAs.
If they do decide to extend line 4 eastward, it should go right to Agincourt in the first phase. No point launching in TBM for < 2 km.

Anything to the west beyond Sheppard West Stn and to the east beyond McCowan would be pure fantasy.

As much as i feel strongly about it getting to Markham & Milner in the 1st phase I'd have to agree that it would be a feat to see even the Provincial politicians get the line past McCowan.

But it will be interesting as there will be a massive uproar in the Malvern community so i doubt it goes unnoticed. They been waiting for the subway for decades so there will be noise and I know from living there and having friends still there that it is still expected. When i moved to Malvern I was shocked to see how many people talked about it and I never heard a peep from the media. Never.

Mississauga, where cars rule city growth
Express buses were one of the first things to be cut when transit sank and will be brought back as ridership demands for it increase.

If you want interlining service, you better hope TTC has learn from the fail one for line 1 & 2 back in the 60's. Base on the current connection from 1 to 4, interlining is DOA. Even if you try to go west and connect to the Spadina Line, it DOA without total rebuilt as well at Yonge.

Based on current ridership of 4 as well 85, an BRT is only needed to get the the far east, but want to see the plan LRT as well to Malvern.

If wasn't for the Ford's the Shepard LRT would be in service today as plan, but would lack the cars on opening date thanks to BBD and we would still see the old fleet still in service until 2022 when the last cars show up.

Out of curiosity, would it be feasible to have a Calgary/Edmonton style full-priority high-floor LRT running along Sheppard at the surface, or is that unrealistic? Also would building cut and cover significantly reduce costs on this corridor?

You've just described big stretches of the LA system which works really well for the most part.

Short answer, yes. Long answer, the size of the platforms makes it harder to design and build, with poorer urban form in the end, than low floor. Given everything involved, if we're talking a primarily surface median ROW I'd be inclined to cut down the platforms in any conversion. The question is, ultimately, what you gain by creating a new and distinct fleet with more difficult infrastructure?

My inclination is that high floor trains of some sort could make sense IF we went back to the SRT and were building something like the Scarborough Y, but given the Scarborough Extension we probably have more to gain by cutting down the Sheppard line platforms. Whatever else Ottawa has done, they've shown that light metro level of service can be achieved with low floor equipment.

Just because its possible doesn't mean its practical. Yes Ottawa does run on Low Floor vehicles, but at a massive cost, that being future capacity. Simply put, by running on low floor vehicles, Ottawa now has less capacity in their trains for no apparent reason. As for the Sheppard Line, there is a good reason of using high floor, even in a median setting, which is the existing subway. Your two options are either A) Have 2 services running along Sheppard, a subway from Yonge to Don Mills, then an LRT from Don Mills out East which not only is it messy, but is extremely inconvenient for passengers travelling to North York Centre. Your other option is to modify the existing subway to LRT which if done using low floor technology, would require changing the height of the platforms which is expensive and frankly unnecessary. Given these scenerios, if we had to make Sheppard East an LRT, the best solution would be to run High Floor LRTs using the existing subway segment.

Third option is to use light metro tech Alstom Metropolis or like Ontario Line, re-use the tunnel sections and run any extensions elevated and at grade. It's not necessary to degrade the service all the way to low-floor LRT.

Ye, and personally I think this might be the best solution. I'm just talking in the context of the original Sheppard LRT plan.

Got it. If we go the LRT route (cheap), I can't see retrofitting the existing tunneled portion.

The station platforms are hollow. They can be lowered. The station box is built for 6 heavy-rail subway car trains, or the length of 5 light-rail car trains. It is partitioned for 4 heavy-rail cars, which means they can work behind the partition to lower the platform before lowering the platform for the remainder.
