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)
