Snowplow - Railway Snowplows

Railway Snowplows

In many countries, railway locomotives have small snowplows permanently attached to their bogies, which also serve as pilots. With others, the snowplow forms part of the obstacle deflector below the bufferbeam. Bolt-on versions also exist, and these attach to the bufferbeam or front coupler. However, larger snowplows exist, which tend to be conversions rather than purpose-built vehicles. Steam locomotive tenders, large diesel locomotive bogies and various freight vehicles have been used, with the snowplow body mounted on the original frames. They are one-ended, with conventional coupling equipment on the inner end. In Canada purpose built snowplow cars (based on a box car with caboose cab located above and behind the blade) are in use in areas where there is a significant snow fall during winter periods (especially in Western Canada, Newfoundland and Northern Ontario). These cars were influenced by the Russell Plow from the United States and used in Canada in the 1880s. Most of the Russell type plows have been retired for smaller custom built railplow or snow blades attached to hopper cars or locomotives.

Conventional operation may see one or two locomotives running together with a snowplow at either end. This enables a snow clearance train to reverse direction quickly if it gets stuck. Alternatively, a single locomotive with bogie plows can act as a self-propelled snowplow by running light engine.

Famous quotes containing the word railway:

    Her personality had an architectonic quality; I think of her when I see some of the great London railway termini, especially St. Pancras, with its soot and turrets, and she overshadowed her own daughters, whom she did not understand—my mother, who liked things to be nice; my dotty aunt. But my mother had not the strength to put even some physical distance between them, let alone keep the old monster at emotional arm’s length.
    Angela Carter (1940–1992)
