SP&S Steam Locomotive # 700: 12-13-14 (Full Clip)

Here is some footage of the Spokane Portland & Seattle (SP&S) steam locomotive # 700 near Oaks Park this afternoon (12-13-14).
The train pulled up next to my camera let out what I think was either steam or smoke (I am not sure), which instantly clouded up my whole shot before continuing on its journey.
This made for some pretty impressive footage.
