It turned out the be the southbound ONR Northlander running about 40 minutes late, lead by 1800, fortunate for me as we had just arrived. I managed to just get my phone out and grab 4 quick shots as it rolled over the street out of the platform and on it's way.
It's a pretty cool location to catch rail traffic as it's so intimate with the surrounding streets and crosses a bridge over the Muskoka River.
As I wasn't expecting to be taking in any rail traffic on the excursion into town, I'd left the Sony cam behind. Too bad as I would have had some of that in-town air horn to present.
