This underpass is gonna be so cool when it's done.

I wonder how they'll handle the GEXR turnout. My guess is a line at the south side will be directly connected to the GEXR line with a switch on the east side of the underpass, before the west side approach is finished.

   

… lots of engineered dirt:

I'm hearing 2nd (or 3rd) hand that the current schedule is for active rail traffic to be routed over the bridge in 4-6 weeks. They'll be able to continue excavation on the north(west) side once that's done.

It would be in line with the Duke closure (at the rails), which is most likely needed to raise the grade ever so slightly that far back from the bridge.

I was wondering, when examining the grade from the bridge: The incline to get on the bridge needs to start PAST Duke, what does that mean for the layover in-between King and Park? it will need an incline too, to match, but it didn't really seem feasible. Won't the Shirley layover need to be complete before grade work can be done for the bridge?

The distance from the overpass to Park (570m) is longer than the distance to Duke (350m). Even Weber is under 500m.

From what I understand (from conversations years ago back when ion was still in the planing/public consultation phase), the current (soon to be former) configuration of the tracks was relatively flat to about King, then there's a steep climb out toward Stratford. The grade separation offered an opportunity to smooth this out by raising the tracks at King. Imagine pinning the tracks at Park, though, and if that's the fixed "start" point, then that's great because the layover facility switch was moved over there. So the layover tracks can probably stay exactly as they are.

plus, I think they made a "back entrance" last summer to the layover facility on the Park St side, so maybe trains could go further down and drive in? Next person past there, double check!

RE: King Street Underpass at the Transit HUB - Canard - 06-15-2016

Yes, sorry I should have mentioned that - the switch to enter the yard is now just past Park. So trains go down beyond Park and then come back and approach the yard that way.

It looks like they are working on water and storm sewers while they continue to raise the rail bed.

They were dumping what looked like topsoil at the HUB site today.

Saturday at 6 p.m. Construction at Duke and CN line. Talked to the construction crew. They are grading to get the CN line over the bridge.

Woah, where do those pipes int he retaining wall lead? Those are massive and many, seems excessive for just water runoff, no?

Hmm... I guess the grading of the area makes that unavoidably the single drainage point for the Breithaupt Block. 4 big pipes to make extra sure that there is no conceivable flood that could overwhelm them.

Uncomfortably tight pedestrian underpasses?

OK, so that would be a pedestrian nightmare, I do agree with that! Big Grin
