Of course, metro trains run underground (in a high humidity environment), not in the sky. But, there's no salt on the SkyTrain. So who knows.
Montréal’s trains don’t just run underground; they are stored there. They never see sunlight at all. More importantly, they never see rain, blowing leaves, snow, or anything of the sort. This has to help with longevity.
