A flanger (also known as a scraper or digger) is a railroad car that clears the space between the rails, generally of ice and snow. While a wedge plow can remove snow above the surface of the rails, the flanger removes snow and ice from below the surface of the rails where the railway wheel flanges fit. [1] Railway locomotives and cars can be derailed if the flangeway is filled. [2]
The flanger blades are lowered below the head of the rail. Blades typically throw the snow and ice to the left of the left rail and to the right of the right rail. Some flangers have a single V-shaped blade extending between both rails while others with a separate blade for each rail are better adapted to lines with guard rails. Some blades work while the car moves either frontwards or backwards, while other flangers have one blade for forward movement and a different blade for backward movement. [3] While early railway wedge plows required a separate flanger, many modern plows also include flanger blades. [1]
To avoid damaging the flanger blades, the operator must raise them when the flanger car approaches a railroad switch or grade crossing. [3] In regions where flangers are often used, signs are posted alongside the tracks to alert the operators to raise the blade.
Wagonways, also known as horse-drawn railways and horse-drawn railroad consisted of the horses, equipment and tracks used for hauling wagons, which preceded steam-powered railways. The terms plateway, tramway, dramway, were used. The advantage of wagonways was that far bigger loads could be transported with the same power.
A railroad switch (AE), turnout, or [set of] points (BE) is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.
Rail terminology is a form of technical terminology. The difference between the American term railroad and the international term railway is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist.
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard.
A rotary snowplow or rotary snowplough is a piece of railroad snow removal equipment with a large circular set of blades on its front end that rotate to cut through the snow on the track ahead of it. The precursor to the rotary snowplow was the wedge snowplow.
A snowplow is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes. Although this term is often used to refer to vehicles mounting such devices, more accurately they are known as winter service vehicles, especially in areas that regularly receive large amounts of snow every year, or in specific environments such as airfields. In other cases, pickup trucks and front end loaders are outfitted with attachments to fulfill this purpose. Some regions that do not frequently see snow may use graders to remove compacted snow and ice off the streets. Snowplows can also be mounted on rail cars or locomotives to clear railway tracks.
The International Railway of Maine was a historic railroad constructed by the Canadian Pacific Railway (CPR) between Lac-Mégantic, Quebec, and Mattawamkeag, Maine, closing a key gap in the railway's transcontinental main line to the port of Saint John, New Brunswick.
The Monson Railroad was a 2 ft narrow gauge railway, which operated between Monson Junction on the Bangor and Aroostook Railroad and Monson, Maine. The primary purpose of this railroad was to serve several slate mines and finishing houses in Monson. According to the Scientific American of 17 May 1890, it was the smallest railroad in the United States.
The Bangor and Aroostook Railroad was a United States railroad company that brought rail service to Aroostook County in northern Maine. Brightly-painted BAR boxcars attracted national attention in the 1950s. First-generation diesel locomotives operated on BAR until they were museum pieces. The economic downturn of the 1980s, coupled with the departure of heavy industry from northern Maine, forced the railroad to seek a buyer and end operations in 2003. It was succeeded by the Montreal, Maine and Atlantic Railway.
The Montreal, Maine and Atlantic Railway was a Class II freight railroad that operated in the U.S. states of Maine and Vermont and the Canadian province of Quebec between 2002 and 2014. It was headquartered in Hermon, Maine.
A road–rail vehicle or a rail–road vehicle is a dual-mode vehicle which can operate both on rail tracks and roads. They are also known as two-way vehicles, hi-rail, and rail and road vehicles.
Tramway track is used on tramways or light rail operations. Grooved rails are often used to provide a protective flangeway in the trackwork in city streets. Like standard rail tracks, tram tracks consist of two parallel steel rails.
A winter service vehicle (WSV), or snow removal vehicle, is a vehicle specially designed or adapted to clear thoroughfares of ice and snow. Winter service vehicles are usually based on a dump truck chassis, with adaptations allowing them to carry specially designed snow removal equipment. Many authorities also use smaller vehicles on sidewalks, footpaths, and cycleways. Road maintenance agencies and contractors in temperate or polar areas often own several winter service vehicles, using them to keep the roads clear of snow and ice and safe for driving during winter. Airports use winter service vehicles to keep both aircraft surfaces, and runways and taxiways free of snow and ice, which, besides endangering aircraft takeoff and landing, can interfere with the aerodynamics of the craft.
The Katahdin Iron Works is a Maine state historic site located in the unorganized township of the same name. It is the site of an ironworks which operated from 1845 to 1890. In addition to the kilns of the ironworks, the community was served by a railroad and had a 100-room hotel. The site was listed on the National Register of Historic Places in 1969.
The rail profile is the cross sectional shape of a railway rail, perpendicular to its length.
A ballast regulator is a piece of rail transport maintenance of way equipment used to shape and distribute the gravel track ballast that supports the ties in rail tracks. They are often used in conjunction with ballast tampers when maintaining track.
A rail fastening system is a means of fixing rails to railroad ties or sleepers. The terms rail anchors, tie plates, chairs and track fasteners are used to refer to parts or all of a rail fastening system. The components of a rail fastening system may also be known collectively as other track material, or OTM for short. Various types of fastening have been used over the years.
Loram Maintenance of Way, Inc. is a railroad maintenance equipment and services provider. Loram provides track maintenance services to freight, passenger, and transit railroads worldwide, as well as sells and leases equipment which performs these functions.
Iron Road Railways Incorporated (IRR) was a railroad holding company which owned several short line railroads in the U.S. state of Maine, as well as the Canadian provinces of Quebec, New Brunswick and Nova Scotia.
The wedge plow or Bucker plow was first developed by railroad companies to clear snow in the American West. The wedge plow forces snow to the sides of the tracks and therefore requires a large amount of force due to the compression of snow. The wedge plow is still in use today in combination with the high-maintenance rotary snowplow.
