Konan Railway operates in one of Japan's snowiest regions, Aomori Prefecture. For the people who live there, heavy snow is unavoidable. For the railway, clearing the snow is crucial to maintaining scheduled operations. To combat the snow, the railway uses a snowplow (which also doubles as a blower) and Japan's oldest active snowplow (a favorite among railfans). See how the railway combats the long, harsh winter and the various ways they tackle the snow.
