In fact, preliminary work on Mount Dennis has already started.

They have moved 2 of the 3 tracks to the north side of the row. There is also a slow order so most of the trains I've been on pass by the area at about 40km/hr.

Don't know if it was ever mentioned, but the total estimated construction value of the On Corridor works package is around $ 8- 9 billion.

Proponents who unveiled the plan May 30 at Toronto’s Exhibition Place noted the project would be Canada’s largest ever P3. Infrastructure Ontario has previously said the third-phase procurement could be worth $8- or $9 billion not including a 35-year operations period, which would be valued at billions more.

A little good news for the Kitchener Line. It's great to see concrete action is being take for expansion. Looks like Metrolinx is studying to see if the bridge over the river Speed will support a second track - the pylons are currently wide enough to support two tracks.

Construction notice: Lane reductions on Macdonell Street and Elizabeth Street starting July 24


Between Wellington Street and Arthur Street
AECOM Canada will be conducting a geotechnical investigation, on behalf of Metrolinx, on Macdonell Street and Elizabeth Street. Work includes the drilling of boreholes.
Work begins July 24
Work is expected to begin on or about July 24, and take about two days to complete, weather permitting.
Lane reductions and delays expected
Macdonell Street and Elizabeth Street will undergo lane reductions during the project. Two way traffic will be maintained at all times. Please follow posted signs for safety. A full road closure is not expected, however, delays should be expected.
Pedestrian access
The sidewalks in this area will remain open and accessible during construction.
Property and business access and parking
All businesses in the construction area remain open and accessible throughout construction.
Every effort will be made to maintain access to driveways in the construction area during working hours (7 a.m.–7 p.m.). Construction activities and equipment movement may temporarily impact access to private property and delays should be expected.

^ML is doing some intensive maintenance on level crossings along the Kitchener line as well. This work has started and will continue into the fall.
As mundane as this work may sound, it will permit higher track speed, and that will eventually translate into faster timings.

I was there early in the week and couldn't get close as you did and a mess. The whole road has been torn up with piles of dirt where none was the last time I was there. From the only angle I could get for a shot show concrete.

Stop off at the new third bridge and nothing has change other than the new 3 track signal mast bridge in place.

I see the old bridge for the now close road to cars to the park has been replaced with a 13.6' precast tunnel for cycles and pedestrians. You can park outside the close gate and walk in. A new retaining wall has been built to allow the new 3rd track to be place for it when it takes place.

July 10/14
To me, it seems work is behind schedule on the south platform at Bramalea as very little has been done since I last saw it months ago. Same for the other platform. No real work has started on the parking structure as of today.

July 14
Come fall, Torbram Road for the CN Grade Separation will be open for both lanes of traffic. Only the topping of the retaining wall and handrails has to be done for the northbound lanes, along with pouring the sidewalk and the road.

Metrolinx Weston Sub grade separation is still a year or so off from being completed. The 4th track bridge is in place, but still has to be back fill. 2 sections of the east retaining wall on the north side is seeing forming and that retaining wall could be done by year end. The south section still has to have its top form with handrail. Still some forming of retaining wall to be done as well.

There is a large section of retaining wall on the west side on the south side beside the new bridge is done. Until they get all east retraining wall and sidewalk in place, can't do the northbound lanes to shift traffic to it so they can build the rest of the west retaining wall, sidewalk and road.

Had a look at new platform for Kennedy GO Station and looks like all the stairs and elevator form work to the new tunnel is done and waiting for the building of the platform and new track. A new switch has been cut in to the existing line north of Eglinton Ave for the new 2nd track on the west side, but no track there yet.

July 8
Boy did they shift the track north of Milliken GO station where the platform was before. Been many months since I last saw it. The track and the curve section push to the west to the point a bridge for both tracks can be built at the same time now. Lots of shoring in place for the bridge and platform at Steeles in place. Lots concrete support of lights and other things has been shore and pour with anchors at the top. Rebar crew working on making a lots of columns support on the north side of Steeles. Work still taking place on the east side of the station where the new tunnel was installed, but no idea what taking place other than forming.

Have photos, but way behind on doing the ones before them and no idea when they will be on line.

Speaking of, are there any plans to eliminate the Scarboro St Crossing ? Correct me if I'm wrong, but it's the only at grade crossing between Bramelea and Union left.

Yes, but the city and Metrolinx are at odds doing it because of the pedestrians. The city wants a tunnel for pedestrians as well traffic, but Metrolinx wants neither. Now this is going back a number of years and haven't seen or heard anymore on it.

Sorry I'm a little unclear. Which grade separation is this and where exactly? cc @crs1026 @smallspy

This may help. The two grade separations are just east of Bramalea GO, and east of the junction between the Halton and Weston Subs. There are two projects, one for the CN Halton Sub (which is nearing completion) and one for the GO Weston Sub (which has been a very painful project). You can see the two road diversions at the very right side of the shot. I zoomed over to show the Bramalea GO station so you get the relative locations.

Not sure if this email update (from July 9th) has been posted. This matter was mentioned back at the Metrolinx town hall in Durham where it was stated that they wouldn't need some of the third tracking on the Lakeshore East corridor. Just out of curiosity, does this mean they'll still add a third track between Guildwood and Rough Hill Stations? cc @crs1026 @smallspy

Lakeshore East Rail Corridor
Update for Rouge Hill GO Station to Pickering Area

Metrolinx is working to transform the way the region moves by building a seamless, convenient and integrated transit network across the Greater Golden Horseshoe. Over the next 10 years, Metrolinx is transforming the existing GO rail system to deliver a whole new rapid transit experience to your community. With more frequent train service you’ll have more options to get you where you need to go.

What has changed?

Initially, it was understood that the Lakeshore East Rail Corridor would have to be widened to accommodate the new third track, but with intensive reviews of the project scope and train service between Rouge Hill GO and Durham Junction (west of Pickering GO Station), Metrolinx determined that it is possible to reduce the entire three-mile three track section while still achieving future GO Expansion service levels.

This now means that there will be limited impact to adjacent trees and landscaping in the immediate future. There will be some work done to the Rouge River Bridge. Also, during Highland Creek Bridge construction there will be some impacts to the section of the Waterfront Trail under the Highland Creek Bridge. The plan for this work is still being finalized, but Metrolinx remains committed to engagement with the surrounding community in advance of and during these impacts.

I don't have any specific information, other than having heard through back channels that the expansion had indeed been scaled waaay back.

The comment about construction of a Highland Creek bridge does make me think that some third track extension will happen. It's a touch over 3 miles from Rouge Hill to Durham Jct, so reading the text literally, the 3-mile reduction would be from Rouge Hill eastwards.

Operationally, if eastbound local GOs can be held at Rouge Hill on a third track, it's possible to run 15 minute locals plus hourly Oshawa Expresses and hourly VIA's while running the same pattern westbound. The choke point is actually at Durham Jct where eastbound GOs will have to cross over the path of westbound VIA's , but expanded use of the south platform at Pickering might mitigate that.

The other choke point discussion is the fourth track from Union to Scarborough Jct, and the flyover/under at that point. That's a huge deal.
