We're witnessing a meet between northbound 207 and southbound 422 at Porquis Junction August 2004. What you're seeing here is SD40-2 1737 rolling through Porquis' Cautionary Limits enroute to Timmins as a Porquis Section Worker visually inspects the consist. 422 (The Northlander) isn't in the shot but is off to the right of where this photo was taken awaiting 207 to clear the way.
