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?
