SNOW SHED Meaning and
Definition
-
A snow shed, also known as a snow gallery or snow tunnel, is a structure specifically designed to protect a roadway or railway line from the accumulation of snow and ice. It is essentially a covered passageway constructed over or alongside a transportation route that experiences heavy snowfall or avalanche-prone areas.
Typically made of concrete, steel, or timber, a snow shed extends over the entire width of the roadway or railway track, creating a safe passage for vehicles or trains. It acts as a shield against the build-up of snow and ice, preventing them from obstructing the route or causing delays. Additionally, snow sheds help mitigate the risk of avalanches and safeguard travelers from potential dangers associated with winter weather conditions.
Snow sheds are strategically designed to redirect or deflect snowfall, allowing it to slide off the structure harmlessly. This prevents snow accumulation on the road or tracks, limiting disruptions to transportation and reducing the need for constant snow clearance efforts.
These structures are essential in mountainous regions or areas prone to heavy snowfall, ensuring the continuous operation of transportation networks during wintertime. Snow sheds have proven to be effective solutions to maintain safe and reliable travel in challenging snowy environments.
Etymology of SNOW SHED
The word "snow shed" is a compound noun formed by combining the words "snow" and "shed".
"Snow" traces back to the Old English word "snāw", which is believed to have Germanic origins. Over time, it has evolved from "snāw" to "snaw" and eventually to "snow" in Middle English.
"Shed" is derived from the Old English word "sceadan", which means "to separate" or "to divide". It is related to the Old High German word "sceidan" and the Gothic word "skaiths", both with similar meanings. In Middle English, "sceadan" transformed into "sceden", and then "shed" in modern English.
When combined, "snow shed" refers to a structure designed to protect railways and highways from the accumulation of snow, predominantly in snowy regions or areas with avalanche risk.
