With tunnelling supposed to start in June or something, will the crews digging under Bathurst and other west end stations have to hurry up because the unstoppable giant earth worm will reach their site relatively quickly?

I don’t know that it is meant to start in June, considering portal/launch shaft excavation is meant to continue through May, the TBM hasn’t been delivered yet, nor have they announced the routing plan for spoil removal (where conveyors dump and trucks pickup).

When the TBMs are launched they move very slowly initially before getting up to speed. Consider this a period of equipment testing and procedural training for operators.

Man, Kotsy has got the Line 3 covered like no one else. I can't match this level of coverage and constant updates. Well done.

Thanks!! It's a borderline compulsion at this point 😂
 
Just dropped by the Moss Park open house, spoke with a construction manager from Ferrovial. It is so refreshing to chat with the experts!

So here’s the scoop:
  • Park soil conditions did not match what was reported by early assessments, meaning the tower crane base would not be stable
  • Though public record anticipated installation in January 2025, it was originally slated for October 2024 around the time of this new discovery
  • This is not an uncommon occurrence, usual mitigation would involve piling beneath the crane
  • However, due to its park land designation, the piles would need to be extracted from the ground upon completion (note that all land north and west of the headhouse will be restored as park land)
  • Instead, additional clamshell crawlers and other equipment are being used to keep on schedule
  • Barring any showstoppers, we can expect the station to reach ground and top out much sooner than other stations, in 2028
 
Am I going crazy here or are they doing track removals where they just installed them...
P.S. Sorry for the sloppy annotation.

No, they are simply removing the old track from the old alignment. Presumably that's to enable the completion of the civil works for the third and fourth rail tracks and the OL itself.

Relaying the tracks themselves is a relatively cheap and easy step, not a big waste - especially if they are recycling most of the materials (somewhere else, possibly) and if they were planning to upgrade anyways ( eg concrete ties). The cost of the civil works and the resignalling is where the big bucks get spent.

This. They'll sell the rails for scrap and recover some of the costs that way (which they'll likely end up being turned into new rails anyways) and clean and reuse (basically sift out the out of spec crap) as much of the ballast as they can, the ties though are being completely replaced as they no longer fit the spec for the rail corridor. The signalling system will eventually be upgraded to ETCS Level 2, for now they'll be reusing the PTC system until then.
