Train Horn Sound.
This comes back to me every time on the episode that I hear it and that train horn was blasting in the background in the last episode.
An old friend who used to post on IMDb bought this up, and the thread went on for ages, thinking it could be a lead into the stories. So does anyone here have a clue as to if it might be a big clue. Or just a general train passing through on a near by track whilst they are filming some where in Canada? And nothing to lead into the story telling? A red herring??
