Interesting that the entrance to the portal is made of block wall in the inner portion rather than formed concrete walls

The poured concrete is where they need strength - it's load bearing.
The concrete block is used where strength isn't needed, but physical separation is, for things such as ventilation or fire separation.

Its just interesting to see a non-bored tunnel these days at all

With Eglinton West now a go and obviously resulting in higher ridership, do you think that ML will begin to operate the section from DM to Renforth as a Metro and then east of it as an LRT essentially creating 2 different lines? The at-grade section is going to seriously effect how frequently the trains can run putting them at essentially a MAXIMUM of every 3 minutes each way due to little signal priority and no rail guard crossings unlike Cal/Edm LRT. Of course an accident along the line also brings the entire route to a screeching halt.
This would not be unheard of and in fact was planned for Eglinton way back when TC was first announced. The only difference was that the Eglinton entire Crosstown was suppose to go way east of Eglinton down Kingston to UT Scar. It would have been 2 separate lines requiring a transfer at Kennedy. Could they do the same here and effectively have 2 lines so the underground portion from SC to Renforth can run at higher frequencies and even be automated? It may seem premature now but it's very possible that the Crosstown could be extended to MCC as the current Transitway is completely grade separated with full stations and hence the extension could be done both quickly and quite cheap.
Like a highway, a transit line is only as good as it's weakest link and due to Miller's LRT fixation, Eglinton has 9 km of it.

For that to happen they better find a way to grade separate Sunnybrooke Park, and to at least create a crossover at or before Science Center. Afaik with the current track layout, the next crossovers are at Laird and Sloane respectively, and creating a transfer point at either of those stations would be incredible silly, all meanwhile limiting the headways possible on both sections of the line or forcing very fast turnaround times. None of these scenerios are exactly ideal.
Edit: Nevermind my memory failed me. I confused crossovers with crossover with storage tracks. Excluding the issue regarding fast turnback times this is definitely doable.

ML posted this Construction Notice today which adds detail about the delivery and operation of the test LRV's for the east end of the line.

Eglinton Ave. will be reduced to one westbound through lane and one westbound right turn lane east of Rosemount Dr., and one eastbound through lane and one shared eastbound through-right turn lane west of Rosemount Dr. while the LRVs are offloaded.

Starting May 25, six (6) Light Rail Vehicles (LRVs) will be moved from the Eglinton Maintenance and Storage Facility (EMSF) to the LRT tracks (guideway) at Rosemount Dr. via truck transport. The LRVs will be delivered one at a time, on May 25, 26, 27, 31 and June 1 and 2.
Once delivered, The LRVs will be connected to the overhead catenary system which powers the vehicles via traction power substations located along the alignment. The LRVs will then travel west at a slow rate of speed to the underground storage area. For the first LRV, crews will walk with the vehicle to validate clearnaces between the vehicle and LRT infrastructure. A Paid Duty Officer will be present as the LRV passes through each intersection.

Light Rail Vehicle Delivery and Testing between Laird Dr. and Kennedy Rd.
May - December 2021
Starting May 25, six (6) Light Rail Vehicles (LRVs) will be moved from the Eglinton Maintenance and Storage Facility (EMSF) to the LRT tracks (guideway) at Rosemount Dr. via truck transport. The LRVs will be delivered one at a time, on May 25, 26, 27, 31 and June 1 and 2.
Once delivered, The LRVs will be connected to the overhead catenary system which powers the vehicles via traction power substations located along the alignment.

What to Expect
Vehicle Delivery
LRVs will be delivered to Rosemount Dr. and Eglinton Ave. E. via transport truck.
Eglinton Ave. will be reduced to one westbound through lane and one westbound right turn lane east of Rosemount Dr., and one eastbound through lane and one shared eastbound through-right turn lane west of Rosemount Dr. while the LRVs are offloaded.

Testing and Commissioning
Testing and commissioning will take place in three phases beginning June 2021:
Clearance and static testing will take place in June and includes a walking inspection of LRVs operating between 0 – 5km/hr
Dynamic testing will take place from July to September and includes testing coupled vehicles, increased speed testing, brake tests, concurrent vehicle testing, and communications and signal systems testing
TTC Driver Training will follow and includes operational training for TTC personnel who will be responsible for operating the LRT once it is in service.
The OCS is energized. At 750v this means the cables are electrified and dangerous if encountered. It is never safe to go near the overhead cables.
The LRVs will cross traffic lanes at intersections between Leslie St. and Kennedy Rd. following dedicated transit signals. Drivers, cyclists, and pedestrians must continue to follow the existing traffic signals and signage and stay alert to where and when left turns and U turns are and are not permitted.
Hours of Work
LRV delivery will take place on May 25, 26, 27, 31 and June 1 and 2, 2021
Clearance and Static Testing will take place in June 2021
Dynamic Testing will take place from July to September 2021.
Testing will take place between 6:00 a.m. to 11:00 p.m., Monday through Friday.
Work may be rescheduled due to weather conditions or unforeseen circumstances.
The contractor may not always work during the permitted hours but may do so at its discretion.
This work may take longer or shorter than expected.
Traffic Details
- Lane closures will be in effect on at Eglinton Ave at Rosemount Dr. on May 25, 26, 27, 31 and June 1 and 2, to accommodate LRV delivery.
- There are no traffic changes associated with phases 1,2 or 3 of testing
- Nine (9) left turn prohibitions are already in effect along Eglinton Ave. E. between Laird Dr. and Kennedy Rd. as part of the final traffic configuration of Eglinton Ave. to accommodate the Eglinton Crosstown LRT.
- Emergency vehicle access on Eglinton Ave. and cross-streets will be maintained.
- North and South bound through movements will be prohibited at Eglinton Ave. and Rosemount Dr. during each delivery.
- Left-turn movements will be restricted in all directions during each delivery.
Pedestrians and TTC Details
There are no changes to existing pedestrian routes or TTC stop locations on Eglinton Ave. between Laird Dr. and Kennedy Rd. for phases 1, 2 or 3 of testing.
Obeying transit signals, LRVs will share the right-of-way with pedestrians, drivers and cyclists at intersections
Other Impacts
Due to the nature of this work, at times there will be noise around the work area.
How long before the brakes fail and they hit a deer?

More likely a squirrel or raccoon. That's why they are moving them one a day over six different days.

The only thing this notice doesn't tell us what is the off loading time and assuming at night. Not sure why the LRV cannot stay on the 401 between Dufferin St and Bathurst St unless there is an overhead issue

Assuming the transportation of the vehicles will take place over night (after midnight and before morning), to avoid the traffic. Assuming actual off-loading would take place on the right-of-way during the day.

The article states that the first vehicle will be walked over the line with an eye to ensuring there are no clearance problems. I would expect that would be done during daylight for reasons of visibility. I wonder whether both tracks will be tested on successive nights Once that is done it makes sense to move the rest at night when traffic is quieter.

...for the same reason why it can't continue on Lawrence under the Barrie Line.

I was looking at the November 2020 images along Eglinton in Google Streetview (interesting to see the progress), and I noticed you can see train being tested near Black Creek - https://www.google.ca/maps/@43.6878...ZsMs_r-mPqxwyGvsfJ7w!2e0!7i16384!8i8192?hl=en
