In this case, the line has been designed and built from the outset as one integrated system, and the testing is proceeding as such. The decision to open the line in sections would have had to have occurred a long, long time ago so that the installation, implementation and testing of all of the various sub-systems that exist on the line could have also happened in a staged manner.

As much as there ought to be plenty of necks wrung over this project, I am pretty confident that the major issues and delays didn’t happen until well after this notional decision point.
And, since we don’t really know where the deficiencies and delays crept in, we don’t know which parts of the system might have been capable of standalone opening. It may have alwaya been harder than people imagine.
Hindsight is 20-20

The August 2021 Google Streetview imagery for Eglinton at the Brentcliffe Portal, looks like they captured a six-car ELRT consist.

But, on closer inspection it's 3 separate 2-car sets parked up. Would that be the period when testing was taking place on the overground section and the western underground section while construction continued around Yonge/Eglinton?

Wtf.... 8% AT THIS STAGE?! What's holding them back?! Also that 20% on operator training is a bit concerning. If it took them that long since the start if summer to get to 20% who know how long it'll take to get the rest of the 80. Do they need 100% on this in order to open and will trg speed up as more operators get through?

Well if verster is using that metric to make his grand announcement to open we are in for a long long wait

Why would he? That would mean opening before he says anything.

How many months (years?) after the TYSSE was finished before all the certificates were completed?

How about operator time then. If it took 3+ months to get to 20% seat time that means take another year to get to 100% unless things speed up very soon

That metric measures seat time for trainers and operators. We know that trainers are a small proportion of the total seat time. They are now pretty much fully trained, so that is likely the bulk of the 20 %. We know that operator training - a much larger number of seat hours - is now under way. I would expect this statistic to change dramatically in a short time. Nothing bad to see here, folks.

I figure they started with a few trainers to get to 20%, now these 20% trainers increase the amount of trainees to 40-50%

So the progress timeline is exponential. I think that's a key takeaway from that graphic, it's not accurate to project progress time linearly. Construction certificates could jump to 60% if 50% of them were processed in one shot.

Construction certificates aren't something to get worked up about. They may be at 8% now, but if they were to submit the remainder all at once - which they could do, as they are simply digital files showing the built form of the line - then the number would become 100%. In terms of progress, it's meaningless.

In terms of the operators, there will be 3 pairs of classes, with the first pair wrapping up shortly. That number probably dates from before the classes started, or shortly after.

Ok, so they won't commit to a handover date. But there are signs that the date must be nearing. The bike path/stairs into Wilket Creek Park from Eglinton west of Leslie are open! The fencing was all there last Thursday when I rode through. Running today, they are gone. (I'm sure this was part of the Crosstown construction; it's been largely ready for a couple of years)

Of course, the stairs into ET Seton Park from the S side of Leslie are still barricaded, but that may be due to the fencing/construction site for the river naturalization.

Hoping that I'm correct!

No, he's not serious. Because actually considering it at this time would be a huge mistake.

When lines are opened in stages, it's because they were either planned to from the beginning (see the Bloor-Danforth line), or the decision was made early enough in the design and construction process that doing so was not detrimental to the rest of the project (see the Yonge North extensions).

In this case, the line has been designed and built from the outset as one integrated system, and the testing is proceeding as such. The decision to open the line in sections would have had to have occurred a long, long time ago so that the installation, implementation and testing of all of the various sub-systems that exist on the line could have also happened in a staged manner. To do it now would thus require new testing to ensure that the portions of the line could operate as such, and that the sub-systems installed on the other sections not opened wouldn't negatively affect the rest of it.

And that ship has long since sailed.

I believe you are over complicating something as simple as a short turn. Short truns are common, happen every day on TTC routes. There are turn around points that can be used. You're implying that the regular testing doesn't test for things like short turns. We often close section of Line 1 and Line 2 and allow them to run on a limited service, only servicing segments of the line, not requiring years of testing to do that. In the end, neither of us is an engineer at Metrolinx, but I would hope, after half a decade, that they look at reasonable alternatives. To not want this is bizarre to me. We should want as many people as possible to have service, if possible.

Even a short turn requires certain things from the signalling system. And the signalling system may not be certifiable until it is operating end to end.

Same with the power supply system. And the emergency lighting system. And the PA and communications systems.

Once the system is certified end to end, short turns are simple. But reversing the order may be a non-starter. It's not about not wanting the service, it's about how the system is built.
