Most notable is that the hardware for a set of crossovers is staged around Progress Ave. That demarcates the North and Central zones of the project. Supposedly Milliken-Progress is to be put in service first, and Progress-Kennedy second. From my observation, there is a lot more to do north of Progress than south of it.
This first video starts at Milliken, heading southward. It shows that apart from some small bits north of McNicoll, the second track bed isn't anywhere near ready for laying track. Lots of water, some excavations still going on, and lots of fiber conduit that remains to be trenched, and much sound fencing to install. Plenty of progress on the tunnels at Agincourt (as there was at Milliken). One has to remember that after the second track is laid, it becomes the single main line while the "old" line is torn out and relaid with vibration matting and then fresh ballast and concrete ties. So really we aren't at the 50% track laid point yet.
I was passing by on foot a few weekends ago and have a slight correction --- I think you have the sequence right, but the work is a bit further along.
They've already completed the process of putting in one finished "second" track to new standards for that Milliken-Agincourt section (with concrete ties, fresh ballast mats etc.), and your train is actually running on it ---- it's mostly on the east side of the corridor (the exception looks to be a little north and south of the McNicoll crossing where it's jogged over to west track's slot).
The old track, which had mostly been on the western side of the corridor, has now been ripped out and torn down to subgrade, where they'll repeat the same sequence to reconstruct to new standards, basically exactly what you described as the followup step.
You inspired me to dig up reaperexpress's video going the opposite direction over the same segment from last year to compare. As you can see, at that point the trains were running on the west side and most of the regrading was going on the east side.
So even through there are fewer visible cases of two parallel tracks next to each other, the north end is in fact more advanced than the south, and well past the 50% mark. That said, I don't see them actually using it right away, as it's not much good without at least that turnout at Progress and double platforms at Milliken and Agincourt.
