Sorry between Bloor and Davisville was better northbound only.

Some of this is in an RSZ

I was riding Line 1 SB yesterday (Dec 31) around 4:30 from Davisville to Bloor. The trains announced slower than normal travel to St Clair, and the outside bit south of Summerhill. I didn't think it was moving that slowly, though I wasn't particularly paying attention, and I was not in any sort of rush

The drop is only 4 km/hr. Barely perceptible.

It’s an embarrassment of a city of this size that we can’t as a TTC maintain 2 subway lines to normal operating speed. I can’t understand why the same piece of track keeps continuously getting slow orders. Is there something fundamentally wrong with the track that they can’t fix right the first time. The speed of travel on line 1 is significantly slower and our whole system can barely be considered rapid transit. There is nothing rapid about it. The lack of pride in operating a system to our own standards is just a sad reflection of how badly this city is rotting under the past and current leadership.

Is there any hope that this situation will get any better?

Davisville was built on an old landfill. The ground is sinking there. To remedy it they need to dig down to the bedrock to stop the track from moving. It would require the line to be closed for an extended period of time.

What they should do extend the yard stub track by tearing down the bridge that it stops at. By putting that track Into service would allow bi directional travel while they fix one track at a time.

But south of the platform doesn't have a potential solution like that. Redoing all the ballast would provide some interim relief but I'm not sure if they could do it in a weekend closure.

As for Rosedale does anyone know what the issue is?

As has been discussed here many times,, politicians love having ceremonies to show off new vehicles or new stations and then claim credit for them. There is less credit (and few ribbon cuttings) to be had for replacing a section of track or unblocking a drain so politicians tend to provide less money for these (somewhat) hidden things. Preventative Maintenance (in transit systems, buildings or ones own home) is the gold standard but it is hard to get through to people that NOT having a flood is a good thing and worth paying for and that it is FAR better than being able to repair a broken pipe that shut the system for days!

That's assuming that trains travel at that speed. I have noticed them going slower than that.

Seconded, it's all fine and dandy to read off the TTC website and claim "the slow zones are exactly X km/hr! You don't understand!"

In reality, as many subway riders will tell you, the subway is almost always slower. Not just slower than what the RSZ webpage would have you think, but much slower than the Google Maps / Service Summary advertised time as well. https://www.ttc.ca/riding-the-ttc/Updates/Reduced-Speed-Zones

I’m not an engineer but can you dig up one side to the bed rock without affecting the other tracks?

You wouldn't dig, but likely drive piles or install caissons. But I don't see you do that with a live track next to you, given some of the accidents that have happened in the past with drilling equipment falling.

I wonder if some kind of grout injection system might work - thinking outside of the box; but I haven't seen it in unconsolidated soils before - and I'm not that kind of engineer.

Yeah, none of that is going to happen so that section will always have slow orders no matter how many times they fix the track.
