Reviewing the images on my computer, I noticed something that I missed when flying the drone. I went back today to get a closer look.
There was a steady stream of trucks hauling away excavated material.
As I was close by I stopped and took a couple of shots of Lawrence East Station and added to the original post. I missed it yesterday.

hopefully this is a sign that the TBM has indeed been repaired and not just them emptying residual material that was sitting there for months.

LOL I'm beginning to feel like a military intelligence analyst reviewing satellite images of some foreign nuclear installation.
There's not much earth in any of those hoppers, so I'm going to be optimistic and conclude that it's newly excavated spoils.
Another parallel question would be, what does the inventory of tunnel wall segments translate to in terms of days of boring.
Tasking a wild guess, I would say they need about a dozen per day of tunnelling - two rounds of six segments. So they have a couple weeks
inventory on hand, but not months of accumulated deliveries.

According to other users of UT, an entire parking lot of TTC owned property has been filled with tunnel liners, in anticipation of resumption of tunnelling. Also I saw a social media post from the comms team that 50% of the tunnel liners were delivered about a year ago, but not sure how that factors in.

Not sure if for Line 2, OL, Line 1, etc. but this yard has been storing thousands of tunnel liners for years: https://maps.app.goo.gl/Z9gPuq6BMdRewXL38

A couple of questions here:
Does week of May 10 mean that they are planning to work 7 days after May 10th?
Do you guys think that they will have to do a road shutdown for all the other roads along the route or only this one because of the issues with soil condition?
While this progress may seem slow, perhaps once they pass this troublesome patch of soil the rate of tunnelling will speed up.....

Because of Doug Ford's policy of only giving us the information he wants us to hear, we're unlikely to know, for sure, what's causing these roads to be closed.
We do know that boreholes were taken along the route and will have informed the contractors proposal, so it's likely that the ground conditions will return to what the TBM was designed for and progress will increase. With the reminder that the only way to know the actual ground condition is to dig the tunnel!

I find it strange that they spent so long working on the TBM from the 401 site yet there is not much evidence left behind...
Also I am surprised that future Scarb centre station is still an empty lot and no digging has taken place. They really should start soon because station construction takes so long!

I think someone said earlier that the entire parking lot was filled with tunnel segments. So if that's true, then they must have moved a significant amount of them to the TBM launch siteFrom this morning..

Something caught my attention close to the parking lot where I staged the drone for the flight...might need military intelligence analysis by @crs1026

The little patch of dirt near the 401 ramps was apparently the site of digging down to repair the TBM cutting head, yet from aerial photos you wouldn't be able to tell that much was done there.
