Surviving C-Liner B Units in Calgary

In an issue of Trains from a few years ago there was mention made of some old CN FM C-Liner B unit shells that are being used as sheds in Calgary, Alberta. That’s basically all it said. Can anyone tell me anything more about these? I’d really like to know more. I’m leaving on Friday for Calagary so I can go to the Calgary Model Train Show (it’s the largest train show in Western Canada, so I’m really excited). I’ve been to Calgary a few times in the past, but had never thought about trying to find them. It would be nice if they would be someplace tht you could get a picture of them.
