ION - Waterloo Region's Light Rail Transit
I saw some tiles up at the Phillip, er, R&T Park station yesterday. It's red. A little more orangish red than in the drawing (that could have been the effect of sunlight at the time of day), but still striking.

Both are powered. They are both offset from the support poles with insulators.

I seem to recall as well, at the open house, the technicians mentioning that the top wire was also the wire which carries the majority of the current, hence it being thicker.

Awesome to hear R&T tiles are going up!! These ones are the ceramic style (like Conestoga) - I can't wait to see them! Depending on if this sunshine holds I might go ride by tonight to check them out.

It'll be the most obtrusive thing in the cores, where there aren't the same power setups, but elsehwhere it hardly seems like it's some horrible new culprit.

I think you meant Borden and Charles (I haven't posted any Ottawa photos recently).

I wish/hope the outboard utility poles can come down, leaving only the OCS poles for the LRT. The ones on Borden certainly look heavily populated so I bet they have to stay. But on Courtland, they look far less utilized. I think the last time I rode through here I decided that maybe they were solely functioning as streetlights now? So maybe they can come down.

Canopy glass installation is the latest in the flurry of work at Frederick station. They've also poured a bit of sidewalk on the Market Square side, are resuming work on the walkway stairs, and are otherwise busy.

Strictly speaking, it will carry more current because it is thicker, not the other way around.

But on the other hand it is thicker by design.

I wonder how different our contact wire is from streetcar contact wire? Or contact wire in other LRT systems, some of which don’t appear to have messenger wire, only contact wire?

You may find https://www.apta.com/mc/rail/previous/20...PWhite.pdf to be interesting reading.  It's about the TTC's wiring upgrade from the legacy 'trolley pole' system to the new 'trolley + panto' system...

Edit to add:  And http://www.apta.com/mc/rail/previous/201...0White.pdf is about the system I wish we were installing.
