That was the LRT proposal. haha

As surely as the sun rises in the morning, so do Toronto transit debates come full circle.

But to what extend are modifications necessary to use standard streetcars?

Obviously the catenary is missing, and track is out a centimetre or so, but it was originally designed for CLRVs.

No need to upgrade permanently to Flexity Freedom standards.

woudlnt this then negate this decades long debate if theyre thinking about keeping the elevated row? wasnt the whole point to dismantle it?

The final design was done in such a way to prevent the use of streetcars

Hence my question.

I thought they couldn't use the guideway?

Can't read anything you need.

Can't see why they can't jury-rig it for buses in one-direction only. That would be useful in the peak direction at rush hour.

Theoretically they just need to pave it. In reality however, it might affect the GO expansion along the Stouffville Line. The SRT station clearance would be another issue. They might need to detour around the stations or demolish them first.

Steve Munro has already analysed why only some of the SRT corridor can be used -

"North of Ellesmere Station the SRT runs through a tunnel that is only big enough for an SRT vehicle which is slightly smaller than a standard city bus, and requires less dynamic clearance because it runs on rails."

and

"There are several problems with using the elevated structure between the GO corridor and McCowan Station.https://stevemunro.ca/2021/02/07/recycling-the-srt/#more-33395

• First is the extra space needed for buses and their dynamic clearance. The SRT cars are narrower, and they fill the structure in which they run. The guideway is actually a pair of U-shaped concrete “lanes” for the SRT track, and could not be used “as is” for buses.
• Second, the station at Midland is integrated with the bridge, and could not be easily modified. (This problem came up during consideration of other modes on the corridor including a subway.)
• Third, access to and from the elevated would require ramps just like the Gardiner Expressway, and these would increase the structure’s footprint at ground level.
• Fourth, operationally it would be much simpler for buses to serve Scarborough Town Centre at grade than to run via the elevated (leaving aside other problems) because they would not be constrained by access points to and from the structure."

Basically it's easier to use the at grade bits of the SRT corridor, and it's cheaper too - more buses for your money!

Steve Munro has already analysed why only some of the SRT corridor can be used -

That' all seems to based on the assumption that bus or streetcar operation on the SRC would be two-directional, not one-directional.

My question was about the cost to make the required changes, not the engineering. Obviously it won't work without some adjustments.

A good reminder in this image how low density this area is. I wonder what it'll look like in 20 years and if the subway will change that?

Thanks for sharing the update. I know some feel the The Star has an agenda with these stories, but without this particular one this man may not have received help.

Glad it worked out.

Probably not to any significant degree. The city admitted in a report that they don't expect the suburban character of the city to change all that much along most of the line.

Sheppard has been around for nearly 20 years now. While there have been some new condo projects, the character of the street hasn't changed to any significant degree.

It'll probably be similar for much of the Scarborough extension.
