1923 Canadian Pacific Snowplow

Although they are seldom seen in action, snowplows are an important part of the railroad scene.

This snowplow, operated in rural New England and Canada, is one of 36 built by Canadian Pacific's Angus shops in Montreal between 1920 and 1929. It is a 20-ton, wedge-type plow made for use on a single track - it throws snow on both sides of the unit. Built without a self-contained power source, the snowplow was pushed by one or two locomotives. Its ten-foot overall width can be increased to 16 feet by the extension of the large hinged wings on its sides. Moveable blades at the front, designed to clear the area between the rails, can be raised at crossings to avoid damage to equipment.

The snowplow's cab contains compressed air tanks that control the wings and blades, as well as providing air for a whistle used by the plow operator to signal the locomotive engineer. The cab also contains a heating stove. This plow was in service from 1923 until 1990.
