Well, transitioning from traditional signalling to ATC within the wye would be better than stopping for many seconds to switch between the two on the main tracks.

TTC has 512 on slow order for the eastbound ramp on the west side of the portal and on the westbound ramp on the east side. Not sure what the issue for this, other than the connection between the old system and the new system for the loop at St Clair West station.

Then, other to increase your post count and your "likes", why are you asking a question that you already know the answer to?

It's pretty easy to find answer to question. ATO will soon be in place on the Line 1 downtown loop, however and obviously, Line 2 has yet and won't getting ATO for a bit

Why do they do this? Basically 501L cars at Long Branch offload by a retaining wall as you can see, requiring passengers to exit onto gravel and tracks. It is a slip and fall hazard, and I am surprised no one has complained about this far...

Maybe they could learn a lot more if they came into the modern age? Unbelievable that this hasn't been done before.

Grinding and Milling are Essential for Rail Quality - Global Railway Review
Rail grinding helps to prevent the dangerous build-up of rolling contact fatigue, and also reduces running noise for line side communities.

TTC is supposed to be the first system in NA with this toy and how do you class other systems that not only don't have them in NA and are older than TTC???

Interesting. Wondering if there's an opposite to rail grinding. So rather than "smoothing out" any variation by grinding a large area flush with the depth of the pitted track, which in a way is fighting fire with fire, some kind of composite or epoxy is laid into the worn out area of track. Effectively filling in the gap and literally smoothing it out. Just a thought, though unlikely such a material exists that could adhere and withstand the weight.

Also out of date if they're not new systems. These have been available in Europe for a generation, exporting them east as well as in the EU.
However, it seems NYC beat Toronto's debut:

You can weld on more steel, but has to be the right grade, oriented and cooled correctly, then ground or milled to form, It could serve in an emergency, but won't last. There's no way to replicate hot rolled steel rail:

It isn't done on tangent track as the heating and cooling cycles will destroy a lot of the properties that the rails need, but yes, additive welding is done all the time to the tips of frogs at switches and crossings.
