^ Sorry @NoahB, or anyone who can answer this - I assume the junction shown above is where the Deux-Montagnes and Anse-à-l'Orme/YUL branches diverge. If so, how will the YUL branch diverge from the Anse-à-l'Orme branch? Will it also be grade-separated, or at-grade (like UP Express)?
This really peaks my interest because this will be the best example of branching (automated) ”metro” services in Canada since the SkyTrain.
Edit: I recently found out about the Devisubox cameras - they’re a great way to check on the status of multiple REM stations and the main junction.

That branch-off will be right by the A-40/Henri-Bourassa/Alfred-Nobel interchange. It looks like it will be a flat junction, which should be fine given the lower train frequency vs. the Boul. Thimens junction.

These Fires really got me thinking - How resilient are the elevated structures on the REM to earthquakes?
It’s surprising to see all the single-pier spans on the West Island branch - even highway overpasses (typically) have/had more piers to distribute the load. Then there’s all the stations being supported by a single (thin) pier with separate platform structures built around them.
Pierrefonds-Roxboro especially, should’ve been built with highway overpass-style concrete-slabs on the sides, like the tail tracks at Deux-Montagnes. Would it have been possible to trench Kirkland instead of going so high up also? I really do respect the effort they made throughout the system though.
As much as I love the REM, these elevated structures really seem flimsy to me. Hopefully there aren’t serious construction quality issues as with Edmonton’s (SE) Valley Line’s piers.
At least the CDPQ really got something right, by deciding on emergency stairwells at intersections, instead of forcing passengers to walk to the nearest station like in Vancouver.
Sending my love out to you all in QC/PQ and NS!!!

Not sure how resilient they are. But not sure the fact that they use single piers is inherently bad.
They those pier spans in Tokyo.
The Yurikamome line: (Google)
Tokyo Monorail:
In Jakarta, another seismically active city, they are building lots of rail with single piers too. Here is their new "Jabodebek LRT" line. (source)

For the elevated section of the Broadway Extension for Vancouver's SkyTrain, some of the girders sit on the column caps, while others are more fixed in place with a concrete plug. It's a short elevated section, so they used girders instead of the segmental post-tensioned system used for longer stretches.
You can see where there's rebar on the column caps in this video:

We have those homely “TR2”s to look forward to.

REM to Brossard is expected to open in August if final testing goes well!
montrealgazette.com
REM's Brossard-Montreal line scheduled to start running by mid-August
News of the light-rail system's long-anticipated opening came hours after it was announced that test runs between Brossard and Central Station will begin Wednesday.

Only 4 to 6 weeks of test runs? I'd have thought they'd have been doing more of that before even starting trial operation, let alone full operation.
You'd think that the agency responsible would be ultra careful after the Ottawa debacle, for a brand new system. I'd think even an extension would see longer trial running.

They've been doing very frequent test runs for a year and a half already, covering two winters. These are the final tests.
