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.
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.

Quote:The system was a traditional direct suspension double insulated system using 1/4” and 5/16” span wire made up with preformed end fittings, fiberglass rod insulators used for span wire insulation at poles, with AGC span wire hanger or cap and cone hangers with 12 inch HS clamp ears to hold the trolley wire, No-Bo section insulators, Type SH trolley frogs and crossover pans and a 2/0 grooved alloy 80 bronze trolley wire.

Neither could the installers, evidently. When do they fix it?

Fix what?! It's perfect!!!!!! It's everything I ever dreamed of. I mean, I might have gone with a slightly tighter kern... and I'm always down for Helvetica, but Clearview is fine, too!
I SWEAR if they had ended up with the all-caps as shown in the concept renderings I would have been DONE

Several letters are crooked (‘h’, ‘f’, ‘i’, and ‘d’). Also, the ‘o’ and ‘e’ are mounted too high (nobody told the installers about overshoot).

That aspect is ugly but authentically Clearview.

You'll want to take up your issues with Pride Signs, they're the ones who did the signage (look closer. it's installed on a common backplane, so was supplied as a finished unit)

I guess we'll see whether they have any.
