Not to mention, we've yet to hit the stage where the rails are getting past Caledonia, I'm not expecting them to reach Chaplin any time soon.
 
I guess my humor got lost with running of trains

This could be TTC Catch All as well

Update: TTC Bus Rerouting at Eglinton Station
Extended to Late-Fall 2020

What Work is Taking Place?
The Eglinton West Station bus loop remains closed while crews perform roof construction for the future Cedarvale LRT Station. Roof construction, currently underway on the east side of the bus loop, has been extended by approximately two (2) months, into late-Fall 2020. During the closure, the 32D Eglinton West bus will continue to extend to Eglinton Station.
The 51 Leslie and 56 Leaside buses will continue to enter Eglinton Station from the Berwick Avenue entrance through to late-Fall 2020. 51 Leslie and 56 Leaside buses will travel westbound on Eglinton Avenue, south on Duplex Avenue, east on Berwick Avenue, and turn left into the bus terminal. Once the Eglinton West Station bus loop re-opens in late-Fall 2020, the 51 Leslie and 56 Leaside buses will resume their normal route into Eglinton Station.

What to Expect
Approximately six (6) TTC buses per hour will travel along this route.

HOURS OF WORK
• The 51 Leslie and 56 Leaside buses will continue to enter Eglinton Station from Berwick Avenue through to late-Fall 2020.

TRAFFIC AND PEDESTRIAN DETAILS
• No changes to traffic or pedestrian routes are expected as a result of this work.

TRANSIT INFORMATION
• The 32D Eglinton West bus will be extended to terminate at Eglinton Station during the closure.
• The 51 Leslie and 56 Leaside buses will use Duplex and Berwick Avenues to access the bus terminal at Eglinton Station
• Please visit www.ttc.ca for more information.

From Thursday October 22 to Friday October 23, crews at Caledonia will be demobilizing the tower crane. To safely remove the crane from the site, two lanes on the north side of Eglinton Ave W will be closed west of Blackthorn Ave. One lane will be open in each direction on the south side of Eglinton Ave. Lane closures will begin as early as 6:00am and last until approximately 5:00pm on Friday October 23. Lanes will reopen as soon as it is safe to do so.
What to Expect
Two lanes on Eglinton Ave will be occupied west of Blackthorne Ave while the crane is safely dismantled. Motorists can expect delays when travelling through the intersection.
Hours of Work
  • October 22 & 23, 2020
  • Lane reductions will begin at approximately 6:00am and last until approximately 5:00pm on Friday October 23.
  • The contractor may not always work during permitted hours but may do so at its discretion.
  • Work may be rescheduled due to weather conditions or unforeseen circumstances.
  • This work may be longer or shorter than expected.
Traffic & Pedestrian Details
  • Periodic sidewalk interruptions – pedestrians will be rerouted to temporary sidewalk.
  • One lane in each direction will remain open for the duration of the crane demobilization activity.
  • All crosswalks will be maintained.
Transit Information
  • No impacts to TTC bus service
  • All TTC bus stops will remain in their current locations.
 
But didn't someone say the private sector can do no wrong?

From link.

The Crosstown LRT project includes a combination of underground stations and street level stops. Along the eastern route of the project, this transition between the underground and surface sections happens between Brentcliffe Road and Leslie Street through a structure called a portal.

After the Eglinton Crosstown light rail vehicles (LRVs) emerge from the East Portal at Brentcliffe, the vehicles will be travelling in dedicated lanes in the middle of Eglinton Avenue.

To accommodate the addition of a dedicated right of way for the rapid transit service it is necessary to widen the City’s roadway for eastbound and westbound lanes between Leslie Street to Brentcliffe Road. Part of Eglinton Avenue has been shifted to the north to ensure that two lanes of westbound traffic are provided that will feature a new sidewalk and bike lane when completed.

To safely accommodate the road widening, a retaining wall north of Eglinton is required. Building the retaining wall requires re-grading the slope leading into Serena Gundy Park and a safe and stable embankment must be ensured. During the re-grading of the slope, tree removals were required. Metrolinx and its constructor take the need for tree removals very seriously and work closely with TRCA and the City of Toronto during this removal process.

The next step is construction of the retaining wall and restoration of the embankment. It is recognized that embankments are ecologically sensitive areas that have to be treated appropriately. Building next to and on embankments is a complicated task that must find a balance between ensuring stability of the slope and re-naturalizing it.
Click to expand...

The restoration strategy proposed a mass shrub planting, with the desired outcome of that the plant material to still reach 15-20 feet in height which would provide some visual buffer for the neighbours of Thursfield from Eglinton Avenue. This approach was proposed based on maximizing the stability of the embankment, which will only accommodate a different depth of soil now that it has a different slope angle. Recommendations from environmental specialists identify that a geogrid solution is the most appropriate in this instance and is a standard approach currently used.

Metrolinx understands that the community would prefer to see the embankment restored with trees. We are working closely with our constructor and the City of Toronto to consider restoration options that would meet best practices for embankment plantings.

On the subject of hill collapse..........may I offer a post of mine from the Toronto Tree thread from earlier this year:

The Toronto Tree Thread

Are there any specific points in the report regarding invasive species?
urbantoronto.ca urbantoronto.ca

From said post:

The choice to keep as many and wide car lanes as they did, and bring the Crosstown up/outside at this location, in this way, resulted in the need/desire for the retaining walls (the bottom of the slope was removed for road-widening resulting in slope stability issues.)

In my, ahem, non-professional opinion, This: (image from The Star, at this link) https://www.thestar.com/news/gta/20...ves-neighbours-worried-about-their-homes.html, need not have happened.

Putting aside that I fundamentally disagreed with the design here: There a few important rules to keeping slopes stable, if you cut down their trees and undercut their toe.

1) Leave the tree stumps; the roots will continue to hold the ground for awhile, likely several months or longer before they rot so much that they no longer help adhesion

2) Resupport the toe as soon as possible

3) Don't get the ground get saturated (tarp it)

Just sayin......

The issue with leaving stumps is that when they rote, they leave a void. Now you have new problem.

If one were intending to retain the original slope grade, above any retaining wall, leaving the stumps would be an appropriate, interim measure.

In this particular case, its my understanding they removed a large portion of the hill all together with the intention of regrading it.

As such, retaining the stumps was not viable.

What was viable was rebuilding the retaining structures forthwith; and replanting forthwith and neither of those was done.

Absent that; at the very least, I would have thought they would have tarped the slope to prevent saturation of the soil which is a common industry practice.

The geotechnical engineers can issue their report later; but at first blush, this appears to be a case of the top layer of soil becoming saturated and slipping off of the more compact clay layer below.

Did they just remove the hill without stabilizing it?

They did take measures to stabilize it.

But they weren't the finished product measures.

Also, they didn't tarp the slope.

****

What they did here wasn't really egregious, bad outcome aside.

I'm somewhat harsh here, in part, because I very much dislike the design choices made in the first place; though I conceded my preferred option would have been materially more expensive.

Be that as it may.

I think the way in which this was phased was less than ideal; and tarping would have been highly desirable; and while one can't be certain, I think it likely those actions would have mitigated the risk of collapse.

In fairness, the entire slope project to this point is only around a six month timeline. Still, I think it could have been compressed.

Look Mon, we are running on rail through a station still being built.......None of walls or roof are form or pour and they are talking about putting rail down now. Geee!!

What going to power that train when no overhead system is in place since nothing there to support it at this time???
Click to expand...

My reaction when I saw the tweet was similar to @drum118 's - there's an awful lot of exposed rebar remaining for anyone to be celebrating victory. But I don't know enough about their construction logic - it may be that having the track bed laid lets them move on to other things or gives them mobility within the site. Even stretching the rail without actually laying it might be a big step forward depending on where the rail is now and how getting that done lets other things get advanced.

What struck me as much more indicative of progress is the notice about demobilization of the Caledonia station crane. That means a certain number of things have been completed.

As to the soil movement - what caught my eye is how more than one article/tweet used a photo of the underpinned Line 1 crossing in conjunction with the event. That took my breath away, until I read further and realised that the event wasn't connected to those crossings. The embankment movement is bad enough, but it's fixable and really not that big a delay. Any event that actually affected the crossings would be a much bigger deal. I thought the authors of those items were sensationalising, although only us sidewalk supervisors may have cared. Joe Public might not have ever noticed.
