In the future Calgary will have at least one new underground section that will likely have long stations just like Edmonton & Dallas. That's because Calgary, Edmonton & Dallas aren't under Vancouver & BC small scale planing & building restrictions. Indeed, the Vancouver & BC power-structure can't slow Ontario, Quebec & Alberta down, but BC continues to think & build smaller scale infrastructure for itself.
