I don't mind the cold thing as it requires people to dress and be prepared for the weather. One impression I have, though, is that some stations like Pimisi look like giant rain and snow chutes right on to the tracks. I hope they have excellent clog-free gutters. I look at the latest renderings for Blair, for example, and wonder if during a torrential downpour where all the rainwater on that middle glass part is supposed to flow:
In general I like the station designs, there are just a few other unfortunate things that could have maybe been avoided, like how this elevator head house creates a blind spot right next to a busy downtown crosswalk. Locating it at least 10 meters further mid block would have been nice.
