Burlington Tunnel
The Burlington Tunnel (also known as the North Avenue Rail Tunnel) is a railroad tunnel located in Burlington, Vermont, Burlington, Vermont and is currently owned and operated by the New England Central Railroad (NECR). According to the inscription on its southern entrance, the Burlington Tunnel was constructed beginning on 1 November 1860, and completed on 17 May 1861 for a predecessor railroad to the Central Vermont Railway. The tunnel runs in a northeast–southwest curve, while the external approach trackage runs from south to east. The street overpassing the Burlington Tunnel is North Avenue (Functional classification of 16; Urban Minor Arterial) which has an Average Annual Daily Traffic (AADT) of about 12,000 vehicles. Tunnel dimensions The Burlington Rail Tunnel, located at Milepost 1.15 of the NECR Winooski spur line, is a long brick masonry horseshoe shaped tunnel that passes through the sandy ridge supporting North Avenue (Burlington) on a curve of approximately four ...

Railroad Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tunne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rouses Point, New York
Rouses Point is a village in Clinton County, New York, United States, along the 45th parallel. The population was 2,209 at the 2010 census. The village is named after Jacques Rouse, a French Canadian soldier who fought alongside the Americans during their war for independence. The village is on the western shore of Lake Champlain at the source of the Richelieu River. Also located in the northeastern corner of the town of Champlain, it is north of the city of Plattsburgh and less than one mile south of the Canada–United States border. History Rouses Point was first settled around 1783 by Canadian and Nova Scotian refugees who were granted tracts of land in reward for their services during the American Revolution. Steamboats were a booming business on this part of the lake; the second commercial steamboat in the world was launched on Lake Champlain, with Rouses Point as its first port-of-call. Steamboat traffic continued on the lake for the next 100 years until displace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Burlington, Vermont
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transportation Buildings And Structures In Chittenden County, Vermont
Transport (in British English), or transportation (in American English), is the intentional movement of humans, animals, and goods from one location to another. Modes of transport include air, land (rail and road), water, cable, pipeline, and space. The field can be divided into infrastructure, vehicles, and operations. Transport enables human trade, which is essential for the development of civilizations. Transport infrastructure consists of both fixed installations, including roads, railways, airways, waterways, canals, and pipelines, and terminals such as airports, railway stations, bus stations, warehouses, trucking terminals, refueling depots (including fueling docks and fuel stations), and seaports. Terminals may be used both for interchange of passengers and cargo and for maintenance. Means of transport are any of the different kinds of transport facilities used to carry people or cargo. They may include vehicles, riding animals, and pack animals. Vehicles may inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Tunnels In Vermont
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shotcrete
Shotcrete, gunite (), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique, first used in 1907 invented by Carl Akeley. It is typically reinforced by conventional steel rods, steel mesh, or fibers. Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions invented by Akeley. In pool construction, however, ''shotcrete'' refers to wet mix and ''gunite'' to dry mix. In this context, these terms are not interchangeable. Shotcrete is placed and compacted/consolidated at the same time, due to the force with which it is ejected from the nozzle. It can be sprayed onto any type or shape of surface, including vertical or overhead areas. Shotcrete has the characteristics of high compressive strength, good durability, water tightness and frost resistance. History Shotcrete, then known as gunite, was invented in 1907 by American taxidermist Carl Akeley to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association Of American Railroads
The Association of American Railroads (AAR) is an industry trade group representing primarily the major freight Rail transport, railroads of North America (Canada, Mexico and the United States). Amtrak and some regional Commuter rail in North America, commuter railroads are also members. Smaller freight railroads are typically represented by the American Short Line and Regional Railroad Association (ASLRRA), although some smaller railroads and railroad holding companies are also members of the AAR. The AAR also has two associate programs, and most associates are suppliers to the railroad industry. Creation AAR was created October 12, 1934, by the merger of five industry-related groups: * The American Railway Association * The Association of Railway Executives * The Bureau of Railroad Economics * The Railway Accounting Officers Association * The Railway Treasury Officers Association William George Besler was its first President.

Double-stack Rail Transport
Double-stack rail transport is a form of intermodal freight transport in which railroad cars carry two layers of intermodal containers. Invented in the United States in 1984, it is now being used for nearly seventy percent of United States intermodal shipments. Using double stack technology, a freight train of a given length can carry roughly twice as many containers, sharply reducing transport costs per container. On United States railroads special well cars are used for double-stack shipment to reduce the needed vertical clearance and to lower the center of gravity of a loaded car. In addition, the well car design reduces damage in transit and provides greater cargo security by cradling the lower containers so their doors cannot be opened. A succession of larger container sizes have been introduced to further increase shipping productivity in the United States. Double-stack rail operations are growing in other parts of the world, but are often constrained by clearance and ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vermont Railway
The Vermont Railway is a shortline railroad in Vermont and eastern New York, operating much of the former Rutland Railway. It is the main part of the Vermont Rail System, which also owns the Green Mountain Railroad, the Rutland's branch to Bellows Falls. The trackage is owned by the Vermont Agency of Transportation except in New York, where VTR operates a line owned by the Boston and Maine Corporation. The rail line employs about 150 people in Vermont. History The Rutland Railway was the only north-south line through western Vermont. A strike in 1953 precipitated the company's ending passenger service. Another strike shut down freight operations on September 25, 1961. The government of Vermont purchased the main line south of Burlington, as well as a branch to Bennington, total, and the new Vermont Railway, incorporated on October 25, 1963, began operations on January 6, 1964.Edward A. Lewis, ''American Shortline Railway Guide'', 5th edition, Kalmbach Publishing, 1996, p. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
