cfmgd posted two great snowplow videos.
The first has a Jordan spreader pushed by Dash 8 CN 2445 on March 4 2009 through Sacré Coeur, Quebec. It goes through the crossing all folded up, then unfolds one wing and plows the siding.
The day before, he caught a self-propelled snowplow (a "broom") plowing the same area.
Well done / tres bien!
