1923 Canadian Pacific Snowplow

This picture was taken at the Henry Ford Museum in Dearborn, Michigan.  In remote areas of Northern United States and Canada, snow removal is necessary to prevent derailing of trains.  This snowplow is one of thirty-six built by Canadian Pacific's Angus Shops in Montreal, Canada between 1920 and 1929.  It is a 20-ton, wedge type plow made for use on a single track that can throw snow both sides of the track.  This snowplow must be pushed by either one or two locomotives.  The moveable "wings," which propel snow away from the track, extend the plow's 10-foot overall width to 16 feet when open.  When standing next to this snowplow it is massive.
