Every winter I try to catch a snow plow in action, but have yet to suceed, since I don't live by the tracks and when the plow runs, the roads are still largely snowed in, particularly those obscure routes that lead to rail lines.
Thus I got very exited when I heard that a snowplow was coming S/B on the Warman sub. Turns out to be a regular broom, of which I've seen dozens... Maybe next winter.
