Does anyone know the progress of the TTC actually tearing up the tracks?

The notice says work should've started in mid-September, but to me it seems the guideway hasn't even been touched yet. It's nearly November now.

More unnecessary and unexplained delays...

I don't know what they've done at the surface sections of the line, but they have absolutely been doing some work elsewhere along the corridor.

Just because work started in September doesn't necessarily mean that they will be working on the most visible parts of the line in September. It's a long corridor, and they have likely staged the work in a reasonably logical (to them) manner.

Hi everyone this is my first post!


So does this delay in tunnelling threaten the entire project timeline? My understanding was that the stations would be dig from the tunnel and then expanded upon.

Also is there any indication when the TBM could be up and running again?

I certainly hope that the TBMs for the ontario line won't also run into these same issues....

Welcome to UT!
You can do the stations at the same time as tunnels see the Ontario Line where the TBM's are only being inserted late next year
Theres no rush tbh since even for the crosstown west, Stations dont even have shovels in the ground for another 1.5 years

SSE has ways to go until 2030

And so it begins:

The photos are a few days late. As of yesterday the gentle green mound has fully been graded.

Sorry, what is the excavator related to, or what work are we looking at in these photos exactly?

The photos were also posted in this project (I think more appropriately) re: Scarborough Centre block C. I believe photos were at/near subject area below as it relates to the subway extension:

I can’t remember a project that ever made its timeline. So based on the past I would assume that they will not hit their 2030 date. Same with Ontario line. Just add half a decade to the timeline and you might not be disappointed.

Welcome to UT.

Unfortunately, when things go wrong or were poorly planned, Metrolinx sometimes avoids communicating updates/revisions... allegedly because of political pressure/image. Examples include line 5, line 7, GO Lakeshore East express trains.

I would bet if you asked them about the line 2 extension, they'd regurgitate the original timeline messaging (along with its benefits) and nothing more... But don't let that stop you from sending an email and sharing here any new tidbits they provide.

Also is there any indication when the TBM could be up and running again?

The TBM is paused for maintenance according to Metrolinx. It sounds like this was expected. Earlier in the year, they indicated that they had to have a continuous dig under the 401, so a pause would seem to make sense (and maybe was planned).

It wasn't planned.

There was (and maybe still is) planned to be a mid-trip stop just south of Lawrence in order to perform regularly scheduled maintenance to the TBM.

But something major has happened with the TBM to cause them to excavate to it at this point. My suspicion is the main bearing on the cutterhead, as that seems to be the most common source of major failure on large diameter TBMs.

Okay yea thats not worth anything 99% chance theyre lying, or just being fed wrong information from the project team.

A first for me... Typically I get obfuscation, but this seems completely as misinformation.

Is it? I thought they told you it was paused for maintenance. Did they tell you something else as well?

If one was driving to Montreal, and the car fell to pieces, you would be paused for maintenance.
