What about the fright trains? Need one or two tracks for non-GO trains.

Dream on as it not going to happen in your life time. Need 5 tracks if you want express trains, otherwise 2 for CP and 2 for GO. Every upgrades taking place is allowing for 4 tracks.

Funny observation to me.........I've been annoyed that the Class 1s, CN and CP long ago stopped painting their bridges for the most part.
Shows a lack of pride to me.
Here, we have a public contractor apparently spending government money to restore the privately owned CP bridge.............but Metrolinx doesn't routinely paint the bridges they own.
How odd.

fright trains only operate on October 31st so its not much of an issue.
For freight trains, like I said, this will only happen if the Missing Link happens, aka removing CP entirely off this line. Its their mainline, they own it, and they will not let GO on it, and the cost they are asking to build more tracks for GO (GO doesnt own the corridor they have to pay CP to build infrastructure, and even run the GO trains, GO trains on the CP Milton corridor are driven by CP engineers) is cost prohibitive. Its basically their way of saying no.
So the only way you will ever see GO trains on this line is if the Missing Link happens, which also is very expensive, but it means no freight trains on this line, so 2 tracks is fine.

The front-page article was fascinating - shows how much more complicated the Crosstown is when compared to a "greenfield" subway extension like TYSSE...

We've just put up a helluva story on the front page about how the underpinning of Line 1 was accomplished at Yonge and the Allen Road.
Entuitive Engineers Are Playing a Major Role in Crosstown LRT Project | UrbanToronto
The success of Toronto's coming Crosstown LRT line is dependent on the success of the builders that are participating in the project for Metrolinx, including Entuitive, a consulting engineering practice which, among other work on the line, designed the underpinning works for the Line 1 subway...urbantoronto.ca

I just want to commend Robert Mackenzie and anyone else at UT involved in creating this piece. Really excellent work!

Fixing this intersection is simple, force cars to turn right and then take a u turn once the LRT is underground

Im very curious, when they were building line 2 under bloor station, did they have the same problems the crosstown lrt is experiencing?

Some of the Eglinton problems have been that they found things they weren't expecting.
Keep in mind Eglinton and Bloor station were both designed and construction started in the late 1940s.
When they came to design Yonge station in the late 1950s and early 1960s, the people who designed and built Bloor station were still on staff working elsewhere. And that's not true a half-century later.

In reading the Entuitive article, I was kinda shocked that the Crosstown stations are deeper than the Eglinton subway stations.
Why?!

Deep tunnel boring.¯\_(ツ)_/¯
Actually is there any info about whether the Eglinton West Subway was planned for boring or cut and cover?

Cut and Cover tunnel construction has become a political nightmare and quite unpopular. Also since the original Yonge Subway was constructed as Cut and Cover, and that Line is really close to the surface, so any future interchange line will have be deeper, and thus use tunnel bores just for the interchange station.
While I'm not 100% certain, when the Eglinton West project was cancelled despite construction starting and them having to fill up the hole with concrete, what was actually filled up wasn't the station box but the launch site of the TBM (station construction wasn't even close to started). Granted, the construction started at Eglinton West which would've been below the existing Eglinton West station, but judging by the fact that the entirety of the Sheppard Subway is bored, I think its safe to say Eglinton West would've been as well.

Eglinton was to bored: https://nationalpost.com/news/toron...he-ground-after-eglinton-lrt-line-is-finished
Also, I understand that "cut and cover" is a no-go nowadays (unfortunately), but I was surprised that the Crosstown boring was deeper than the Eglinton subway boring - and couldn't understand why.

Most likely deeper foundations along the corridor, but it could also be the fact geotechnical information has changed since then, and the material they're proposing boring through would be easier/quicker to bore through.
