I have to correct you. They're not contactless. The one in Bordeaux has a power pickup in the ground. That would not work in the snow and ice in Montreal, that's for sure.
The other system is from Alstom, and it also touches the ground. They would have to show me that it works with two inches of ice, like we have in Montreal. So on the ground, if it's not induction, magnetic or something, I don't think it would work in our winter.
