The wedge plow typically required several locomotives to propel the plow with enough force to push through the snow. High speeds of up to 50 mph (80 km/h) were required to achieve an adequate propulsion for the removal of snow. [10] Sometimes, as many as 14 locomotives were used in the process. [8]
Rotaries of newer construction are either diesel- or electric-powered. Many steam plows were converted to electricity. Some electric plows can take their power from a locomotive, while others are semi-permanently coupled to power units, generally old locomotives with their traction motors removed; these are colloquially called snails.
Alternatively, a single locomotive with bogie plows can act as a self-propelled snowplow by running light engine. [citation needed] An example of a locomotive with a snow plow pilot. Via Rail, among other railways, has integrated plow blades with the front pilots of their locomotive fleet to clear thinner accumulations of snow as trains run. [16]
The Snow Train Rolling Stock, located in Railroad Heritage Park in Laramie, Wyoming, consists of five pieces of Union Pacific Railroad rolling stock.The five vehicles, which are a snow plow, locomotive, tender, bunk car, and caboose, form a snow train, a type of train used to clear snow from rail lines.
On a mainline locomotive, the cowcatcher has to successfully deflect an obstacle hit at speed. The design principle is to push the object upwards and sideways out of the way and not to lift the locomotive on impact. The typical shape is a blunt wedge with a shallow V-shape in plan.
Railroad plough from the Military Museum in Belgrade.The hook can be raised for transportation or lowered for track destruction. A railroad plough is a rail vehicle which supports an immensely strong, hook-shaped plough.
The Rock Island Snow Plow No. 95580 in Limon, Colorado is a railway snowplow which was listed on the National Register of Historic Places in 2018. [1] It is termed a "Single-Track Wedge Plow". It was created as a snowplow by the Chicago, Rock Island and Pacific Railroad in 1951, rebuilding from a retired steam locomotive tender.
A large snow plow was fixed to the front of the locomotive in 1879, and it performed snow clearing duties on the Virginia & Truckee lines during the winters for most of its operational life, in addition to its normal passenger hauling duties.
