OMG SO much relief it is left justified, you have no idea
I still can't unsee the elephant sucking in a $20 bill haha, even as the staunchest LRT supporter. At least the elephant isn't white.
Hah, now I can't either!
Does it change color when a train is getting closer?, oh, ya, never mind, lol
Note: this logo is on the drivers' building, not the feature wall.
Wasn't there a time lapse camera on-top of the pharmacy building or nearby that was recording the progress at the King underpass @ Victoria?

Did that footage ever get released?
Is the camera still rolling?
I would think they'd wait until it's 100% complete before releasing (rather than release 90% and then... re-release when it's 100% complete).

Progress at Frederick.

[attachment=3435]
Close-up of the not-yet-welded temporary fixing between two rail segments.

[attachment=3436]
Lots of rebar for that half-wall on the backside of the platform.  Love the features added to the forms to indent the concrete!

[attachment=3437]
Transit Hub stop.

[attachment=3438]
Rails just roughed in, here.

Mike Boos pointed out that it looks like there's going to be a very wide MUT on the sides through here.

Crossover at Cameron Heights, on Charles.

[attachment=3441]
The crossover is set up as trailing-point, meaning if a train wants to get on the "other" track, it has to pass the crossover, then reverse through it. This makes it safer, because in the event of a switch failure you'll never have a condition that could lead to a head-on crash.

With that in mind, the lamps at the left are for a train on the left tracks, about to move through the first switch ("facing point"). "|" means the switch is set straight, "/" means it's set to the right, and "-" means it's not safe to proceed (either because the switch is moving, or there's a fault).

The lamps on the right are simply indicate that the trailing-point switch it is about to move through is either clear ("|") or not clear/set the other way ("-").

Looking down Charles, toward Stirling.

Finished OCS on Borden!
3/4 - Sunday, March 19, 2017

[attachment=3444]
Bottom end of Borden, where the tracks meet the Huron Spur.  See those signs on the right?  Will get to those in a moment...

[attachment=3445]
Close up of some of the hardware to hold the contact wire in place through a curve.

The little "kinked" arms down below are called registration arms. They allow some vertical movement but no lateral movement, when the train passes under.

[attachment=3446]
Lots of clamps and insulation and so on up top, for the messenger wire.

[attachment=3447]
The contact wire actually isn't a "wire" - it's a copper profile with a dovetail in the top, that these clamps can clip on to!

[attachment=3448]
Looking back up Borden, toward Courtland.  (Hi, ballast cars!)
4/4 - Sunday, March 19, 2017

[attachment=3449]
...there's that "trail".  I guess it's trafficked enough that a sign warning the LRV operators to be cautious was necessary.  Funny how they noticed this one (and signed it), but missed Traynor...

[attachment=3450]
Crossing arms at Waterloo Town Square.

[attachment=3451]
Catpoles in place now through here, too.

[attachment=3452]
I just noticed that the stubby arm on the right is actually too short - it doesn't even reach the guide fork at the top!

[attachment=3453]
Maaaaaaaaaaasive arms for the access to Cora's roll-up door.  And I guess for the square itself?  I really hope people in other cities pitching for Light Rail don't look too closely at stuff like this on ours.

These are going to corrode though, right?  Not galvanic corrosion so much, but jut thinking about bare copper exposed to the environment.  One end of the spectrum being the green Parliament building roof, opposite end being something like plumbing in an older house that's oxidized.
I would think that the carbon strips on the pantograph running over the bottom of it every 10 minutes will keep any form of surface reaction from forming on the surface that matters... just like the rails themselves are very, very rusty right now - and after a little bit of run-time with the trains, they'll be shiny and smooth. Next time I'm in Toronto I'll try and take some close-ups of the contact wire for the streetcars, and see how they look.

(I should point out though that this is nothing new and literally thousands of electrified railways around the world use this setup, so I don't think it's a problem)

These are going to corrode though, right?  Not galvanic corrosion so much, but jut thinking about bare copper exposed to the environment.  One end of the spectrum being the green Parliament building roof, opposite end being something like plumbing in an older house that's oxidized.

I'd imagine since it is in use, that shouldn't be an issue. I can't imagine them using a technology that is going to create issues. Don't we already have that in Toronto?
