This hasn't happened in Bordeaux, never seen any reports as such, but they don't get downpours like we do.

Some one managed to get a bicycle (frame ?) under a tram with resulting fireworks.
The Dubai installation apparently has brushes ahead of the pickup shoes to sweep sand of the power rail. Presumably it isn't an electrical hazard, but would make the wear rates of the shoes and rail quite excessive. Note the shoes are in pairs so in theory one should always make contact even if paper or other rubbish temporarily insulates one.
