Gary Lee posted some videos of the New Brunswick Southern Railway working in the snow. First, a short one of the snowplow in McAdam.
Next, NBSR 2318 in the blowing snow.
NBSR 2317 and 2612 push a cut of cars back toward the McAdam station.
OK, this one isn't NB Southern but it does have snow - VIA Rail's Hudson Bay train idles at the Winnipeg train station.
