Toronto GO Transit: Davenport Diamond Grade Separation | ?m | ?s | Metrolinx

Nope, and there likely won't be.

And no, the reason isn't that the work isn't ready to be done. It is.

But the problem is that with all of the other work being done on the corridor this weekend that there was not a way to move a train into place to test the various elements after the work was done on Sunday night. Which means that the first train over the work would have been the first southbound revenue move on Monday morning. And that is not an option for any number of different reasons.

They'll postpone the cutover by a couple of weeks, and ensure that it won't coincide with too much other work going on in the corridor so that they can have the test train ready at the site.

Makes sense. Safety first.

The, um, big yard in South Etobicoke couldn't spare a trainset?

Walked by the Bloor GO works and the elevated section of the grade crossing this evening. The cladding is coming along with the plastic film cover now removed from what I saw. I was surprised to see that the panels actually somewhat provided a nice smoky mirror effect of the sunset. Still too much grey, but at least they interact with the natural light somewhat (see third image).

how long will this work usually take? can they have it done at the middle of the night and have a night train test it?

These kinds of things usually take about 36-ish hours straight.

The trackwork itself is quite easy and can be done in several hours. (Then, multiply it by two.....still not too bad though.)

The bigger issue is the connections for the signalling. Those take longer, and involve communications back to the RTC Centre to ensure that everything is working correctly.

There's some sort of work scheduled for Parkdale this weekend as well, apparently.

Makes sense. You don't want to rush opening the new guideway just to have service cancelled due to some issue. This is mitigating egg-on-face and customer disruption in the long run.

Also, Metrolinx is aware Twitter has a 280-character limit per tweet, right?

the words "testing and training" seem to imply at minimum a month to several..... 😒
 
I would have thought that the testing and training process would have been well thought out and vetted before this date. Adding requirements at this late date does not reflect well on ML as a buyer and/or project manager.

This sounds more like lack of coordination or oversight for all the sub-project leads who wanted to work on the tracks during a work window. I can believe that somebody only just discovered that there was no clear alley for a test train.

If in fact it's just a matter of conflicting track projects, it's remarkable that the smaller projects would be kept moviing but the larger project cutover is postponed. If nothing else, the contractor would want to get paid for completion of the flyover. Maybe the lesser works have binding penalties for rescheduling also. One wonders what was so pressing about smaller work tasks that they would override the flyover.

OTOH - if somebody is only just having second thoughts about whether the project is ready for acceptance.....

I can't rationalise this to anything other than work not managed effectively.

Did they build a tunnel anywhere around this area or will it now be impossible to get to the station except for the Bloor entries? IIRC there was an entrance from the railpath at one point.

If memory serves, there will be a tunnel entrance from the east via Randolph Avenue (i think it's to connect to the current tunnel that exits behind the FreshCo on the west)
