Bellows Falls Tunnel
The Bellows Falls Tunnel is a railroad tunnel located in center of the Village of Bellows Falls, Vermont, Bellows Falls within the Town of Rockingham, Vermont, adjacent to the Connecticut River, and is currently owned and operated by the New England Central Railroad (NECR). The Vermont Valley Railroad originally constructed the tunnel in 1851. Partially cut through solid rock, the tunnel was built with rough-cut stone blocks, where each portal was decorated with radiating voussoirs around their horseshoe shaped arches. The stone blocks average about 18 inches deep as observed at the tunnel portals. Record information available from the NECR would indicate that a separate support system exists above the masonry tunnel supporting the hotel building to the north of the Bridge Street roadway which is also directly above, and crosses perpendicular (east/west) to the tunnel below. The tunnel runs in a north/south direction and is located at Milepost 144.56 of the NECR connecting the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railroad Tunnel, Bellows Falls VT
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 Track (rail transport), 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 Railroad tie, sleepers (ties) set in track ballast, 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 friction, frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The rail transport operations, operation is carried out by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bellows Falls, Vermont
Bellows Falls is an incorporated village located in the town of Rockingham in Windham County, Vermont, United States. The population was 2,747 at the 2020 census. Bellows Falls is home to the Green Mountain Railroad, a heritage railroad; the annual Roots on the River Festival; and the No Film Film Festival. History The community was settled in 1753 by colonists of English descent, who called it Great Falls. Later the settlers renamed the town for Colonel Benjamin Bellows, a landowner, but kept the name Great Falls for the waterfall, a translation of their Abenaki name, "Kitchee pontegu." In 1785, Colonel Enoch Hale built at the falls the first bridge over the Connecticut River. It was the only bridge across the river until 1796, when another was built at Springfield, Massachusetts. The bridge was later replaced. Two bridges currently link Bellows Falls to New Hampshire: the New Arch Bridge (also called the Church Street Bridge), which replaced the Arch Bridge in 1982, and ...

Vermont
Vermont () is a state in the northeast New England region of the United States. Vermont is bordered by the states of Massachusetts to the south, New Hampshire to the east, and New York to the west, and the Canadian province of Quebec to the north. Admitted to the union in 1791 as the 14th state, it is the only state in New England not bordered by the Atlantic Ocean. According to the 2020 U.S. census, the state has a population of 643,503, ranking it the second least-populated in the U.S. after Wyoming. It is also the nation's sixth-smallest state in area. The state's capital Montpelier is the least-populous state capital in the U.S., while its most-populous city, Burlington, is the least-populous to be a state's largest. For some 12,000 years, indigenous peoples have inhabited this area. The competitive tribes of the Algonquian-speaking Abenaki and Iroquoian-speaking Mohawk were active in the area at the time of European encounter. During the 17th century, Fr ...

Vermont Valley Railroad
The Vermont Valley Railroad was a line in Vermont and New Hampshire, running from Brattleboro to the Vermont-New Hampshire line at Windsor, now part of the Connecticut River Line. Hugh H. Henry (1814-1869) of Chester, Vermont was an original incorporator, and was chosen as its first president. He served from 1848 until his death. In New Hampshire, the line was operated as the Sullivan County Railroad. The line was eventually owned by the Connecticut River Railroad, who in turn leased the line to the Boston and Maine. In 1988, the Interstate Commerce Commission ordered the Boston and Maine (B & M) to sell it to Amtrak, with trackage rights staying with the B & M. Amtrak was allowed to sell it to the Central Vermont Railway, part of the Canadian National Railway. The CV obtained the line on September 9. The sale was made because the track condition was not suitable for running Amtrak's Montrealer passenger trains, and Amtrak had to discontinue service on April 5, 1987. Service r ...

Voussoir
A voussoir () is a wedge-shaped element, typically a stone, which is used in building an arch or vault. Although each unit in an arch or vault is a voussoir, two units are of distinct functional importance: the keystone and the springer. The keystone is the centre stone or masonry unit at the apex of an arch. The springer is the lowest voussoir on each side, located where the curve of the arch springs from the vertical support or abutment of the wall or pier. The keystone is often decorated or enlarged. An enlarged and sometimes slightly dropped keystone is often found in Mannerist arches of the 16th century, beginning with the works of Giulio Romano, who also began the fashion for using voussoirs above rectangular openings, rather than a lintel (Palazzo Stati Maccarani, Rome, circa 1522). The word is a stonemason's term borrowed in Middle English from French verbs connoting a "turn" (''OED''). Each wedge-shaped voussoir ''turns aside'' the thrust of the mass above, transf ...

A bellows or pair of bellows is a device constructed to furnish a strong blast of air. The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to fill the cavity when expanded, and with a tube through which the air is forced out in a stream when the cavity is compressed. xford English Dictionary, 2nd ed: bellows/ref> It has many applications, in particular blowing on a fire to supply it with air. The term "bellows" is used by extension for a flexible bag whose volume can be changed by compression or expansion, but not used to deliver air. For example, the light-tight (but not airtight) bag allowing the distance between the lens and film of a folding photographic camera to be varied is called a bellows. Etymology "Bellows" is only used in plural. The Old English n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plate Girder Bridge
A plate girder bridge is a bridge supported by two or more plate girders. Overview In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape rather than I-shape. The first tubular wrought iron plate girder bridge was built in 1846-47 by James Millholland for the Baltimore and Ohio Railroad. Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders are usually prefabricated and the length limit is frequently set by the mode of transportation used to move the girder from the bridge shop to the bridge site. Generally, the depth of the girder is no less than the span, and for a given load bearing capacity, a depth of around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
