Flanger (railroad)
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. Railway locomotives and cars can be derailed if the flangeway is filled. 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 rail (rail), 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. While early railway wedge plows required a separate flanger, many modern plows also include fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flanger (271926001)
Flanging is an audio signal processing, audio effect produced by mixing two identical audio signal, signals together, one signal delayed by a small and (usually) gradually changing period, usually smaller than 20 milliseconds. This produces a swept comb filter effect: peaks and notches are produced in the resulting frequency spectrum, related to each other in a linear harmonic series (music), harmonic series. Varying the time delay causes these to sweep up and down the frequency spectrum. A flanger is an effects unit that creates this effect. Part of the output signal is usually fed back to the input (a "re-circulating Delay (audio effect), delay line"), producing a resonance effect which further enhances the intensity of the peaks and troughs. The phase of the fed-back signal is sometimes inverted, producing another variation on the flanger sound. Origin As an audio effect, a listener hears a "drainpipe" or "swoosh" or "jet plane" sweeping effect as shifting sum-and-difference ...

BattenKill Railroad - Flanger
The Batten Kill, Battenkill, or Battenkill River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed October 3, 2011 river rising in Vermont that flows into New York and is a tributary of the Hudson River. It is the longest Hudson tributary on that river's east. As " kill" means a creek, the name "Battenkill River" is pleonastic. The mouth of the Batten Kill is in Easton, New York, and the source of the river is in East Dorset, Vermont. The river is known for its fishing, as it has a prominent trout population. The Shushan Covered Bridge crosses it at one point, and the headquarters of the Orvis Corporation are also located along its course. The Batten Kill valley is home to the Tour of the Battenkill, the largest road cycling race in North America. The Native American name for the river is either ''Dionoondehowee'' or ''Ondawa''.

Railroad Car
A railroad car, railcar (American and Canadian English), railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system (a railroad/railway). Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units. The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner, though the term has other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries "railcar" refers specifically to a self-propelled, powered, railway vehicle. Although some cars exist for the railroa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wedge Plow
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. Function Three features are required for optimum performance: # The plow has a smooth surface so snow will slide over the plow face rather than accumulating to be pushed along as an increasing mass. Wooden plows were carefully constructed of individually fitted boards and painted frequently to maintain a smooth surface. Steel plows can be sprayed with water in sub-freezing temperatures to form a smooth layer of ice on the plow surface. # The plow has a horizontal wedge to lift snow above the level of snow accumulation beside the track. A cutting edge low above the rails usually employed a cast iron or steel leading edge for durability against ice and fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flange
A flange is a protruded ridge, lip or rim (wheel), rim, either external or internal, that serves to increase shear strength, strength (as the flange of an iron beam (structure), beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe (fluid conveyance), pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a railroad car, rail car or tram train wheel, wheel, which keep the wheels from derailment, running off the rail profile, rails). Flanges are often attached using bolts in the pattern of a bolt circle. The term "flange" is also used for a kind of tool used to form flanges. Plumbing or piping A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange). A blind flange is a plate for covering or closing the end of a pipe. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bangor And Aroostook Railroad
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. History The company was incorporated in 1891 to combine the lines of the former Bangor and Piscataquis Railroad and the Bangor and Katahdin Iron Works Railway. It was based in Bangor and lines extended from there to Oakfield and Houlton in 1894. The line was extended from Houlton to Fort Fairfield and Caribou in 1895. A parallel branch line was extended from Oakfield to Ashland in 1896. A branch was built from Caribou to Limestone in 1897, and the main line extende ...

Bangor, Maine
Bangor ( ) is a city in the U.S. state of Maine and the county seat of Penobscot County. The city proper has a population of 31,753, making it the state's 3rd-largest settlement, behind Portland (68,408) and Lewiston (37,121). Modern Bangor was established in the mid-19th century with the lumber and shipbuilding industries. Lying on the Penobscot River, logs could be floated downstream from the Maine North Woods and processed at the city's water-powered sawmills, then shipped from Bangor's port to the Atlantic Ocean downstream, and from there to any port in the world. Evidence of this is still visible in the lumber barons' elaborate Greek Revival and Victorian mansions and the 31-foot-high (9.4 m) statue of Paul Bunyan. Today, Bangor's economy is based on services and retail, healthcare, and education. Bangor has a port of entry at Bangor International Airport, also home to the Bangor Air National Guard Base. Historically Bangor was an important stopover on the Great Ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmonds, Washington
Edmonds is a city in Snohomish County, Washington, United States. It is located in the southwest corner of the county, facing Puget Sound and the Olympic Mountains to the west. The city is part of the Seattle metropolitan area and is located north of Seattle and southwest of Everett. With a population of 39,709 residents in the 2010 U.S. census, Edmonds is the third most populous city in the county. The estimated population in 2019 was 42,605. Edmonds was established in 1876 by logger George Brackett, who bought the land claim of an earlier settler. It was incorporated as a city in 1890, shortly before the arrival of the Great Northern Railway. Early residents of the city were employed by the shingle mills and logging companies that operated in the area until the 1950s. The hills surrounding Edmonds were developed into suburban bedroom communities in the mid-to-late 20th century and subsequently annexed into the city. Edmonds is a regional hub for the arts, with museums, sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guard Rail (rail)
In rail transport, guard rails or check rails are rails used in the construction of the track, placed parallel to regular running rail to keep the wheels of rolling stock in alignment to prevent derailment. They are generally used along areas of restricted clearance, such as a bridge, trestle, tunnel, or level crossing. They also help to minimize damage to the structure and allow easier post-accident cleanup. History Although guard rails in some form have been used as long as there have been trains, the precursor of the guard rails in use today was detailed in , filed in 1893 by Gorham B. Ames, based in Laconia, New Hampshire, US. Applications Bridges Guard rails are an essential component of railroad bridges. Their presence prevents a derailed train from striking and damaging bridge components, or deviating from the track enough to leave the tracks entirely and roll over or fall. Sharp curves On sharp curves, guard rails may be placed inside the inner rail, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
