	Rotary snowplow - Wikipedia, the free encyclopedia
		A rotary snowplow from the Oregon Short Line on display at the Mid Continent Railway Museum in North Freedom, WI.
		The rotary was invented by a Canadian dentist in 1869, but a prototype wasn't built until the Leslie Brothers constructed one in 1883.
		Early rotaries had steam engines inside their carbodies to power the blades; a few are still in working order, and in particular one on the White Pass and Yukon Route in Alaska performs annual demonstration runs through thick snow for the benefit of photographers and enthusiasts.

	Denver & Rio Grande Western steam rotary snowplows
		Snowplow ON was based in Salida for use on Marshall Pass and Poncha Pass, as well as the Monarch branch, and occasionally on the lines from Gunnison (Baldwin, Floresta and Crested Butte branches).
		Working on an operating steam rotary snowplow was tough because of the vibrations caused by the spining snow-cutting wheel, the deafening noise of the exhaust and the rough ride of the plow which was devoid of any suspension.
		Snowplows OM and OY remained in use on the D&RGW until the end of its narrow gauge operations in 1968 (after that, only tourist operations remained on the Durango - Silverton line, where the rotaries were not used).

		A large snowplow on a main street in Washington, DC A small wedge plow mounted on a passenger train in Lower Austria
		A snowplow (or snow plow, US English; in UK English, snowplough or snow plough) is a vehicle, or a device intended for mounting on a vehicle, for removing snow and sometimes ice from outdoor surfaces, typically those serving transportation purposes.
		When snowfalls accumulate above a certain height, snowplow operators may be seen clearing primarily designated "snow routes", often for the exclusive use of emergency vehicles such as fire trucks.

		The Rotary snowplow was invented in 1883 by Orange Jull.
		Most rotarys were converted in the late 1950's to run off deisel electric using traction motors and a RSPU (rotary snowplow power unit, normally and F7b).
		BNSF's rotarys came from various mergers from the Great Northern, Northern Pacific, Sante Fe, and the CB&Q. BNSF also has a Williams Brothers boiler MFG plow, built in the late 1950's as a competitor to the Rotary,It was called the Sno-Flyer.

	Rotary Snowplow
		Rotary Snowplow #10 was built in 1907 by Alco-Cooke for the Northern Pacific Railway.
		Rotary snowplows are considered the big guns of snow fighting and were used to clear deep snow.
		The "rotary" name refers to a large wheel on the front of the unit.

	McCloud Rails - 1952 Rotary Plow
		The rotary plow employed a giant rotating plow blade that enabled the machine to literally chew through snow drifts, with the snow thrown up to 200 feet away from the rails.
		However, a rotary came east at least as far as Bartle, and possibly all the way to Car A, in 1952, and in March 1969 after a series of storms that dumped 20 feet of snow on the railroad a rotary plowed all the way into Pondosa.
		The McCloud borrowed SP Rotary #208 in early 1969 to clear the railroad of 20 feet of snow.

	Southern Pacific Rotary Snowplow Info Page
		SP's Rotary Snowplows were originally built with steam power, but were rebuilt during the 1950's, with the blade being powered by diesel locomotive traction motors.
		The Rotaries trucks are rigid to help prevent derailments and keep the Rotary Blade at a constant height from the railhead, also the rotaries are chained to their respective 'snail'.
		The Rotaries and 'snails' are part of the Maintenance of Way (MOW) Roster, so carry SPMW numbers, respective snails carry the same number as their Rotary, with the prefix 8.

	Summit Historical Society of Summit County
		In the years before there were snowplows as we know them, there were rotary snowplows, huge machines whose giant, snow-blowing and -cutting fans or blades cleared narrow-gauge railroad tracks, throwing snow 30 feet away on both sides of the rails.
		The rotary snowplow you see in the Breckenridge Rotary Snowplow Park is not the one used by the Colorado & Southern Railway to get from Como to Breckenridge via Boreas Pass; the track, however, runs on the original right-of-way.
		This snowplow is one of only five known narrow-gauge rotaries in existence.

		A pilot snowplow is a plow that is fastened to the front of the locomotive and is designed to push snow off the track.
		In the yard, we still have one of the pilot snowplows that was fastened to the front of a steam locomotive.
		The reason for this is that if the rotary derailed and the other locomotives become bogged down, the last locomotive would be pointing in the direction that they had just come and could hopefully pull the entire mess out.

		We also cover rotary plows and have a picture of a NY Central rotary snowplow.
		Rotary plows usually run on steam power, and are also quite hard to find in still-running order, plus a water tank would be necessary and a coaling tower, all things which went the way of the steam engine.
		A rotary snowplow does not have to be steam powered, for example, you can use standard traction motors to turn the rotary blades.

		Orange Jull produced a competing model with a large rotating spiral screw in 1890 to 1892, but this model was not as successful as the earlier Leslie plow.
		The development of the rotary snowplow provided a more efficient way to clear heavy snow from the tracks, and enabled the trains to run under harsher conditions.

		This machine is a Leslie Rotary Plow, originally built in 1927, and constantly modified by SP to make it suitable for the unique snow conditions on the "Hill" between Roseville, CA and Sparks, NV.
		Normally, the rotary plows are placed on either end of a consist, which would consist of a plow, snail, three or four locomotives that provide tractive power, a snail and a rotary facing in the opposite direction.
		There are controls for the rotary wheel, both speed and direction, as well as the locomotive consist providing the tractive effort.
