Yancopin Bridge
The Yancopin Bridge is an abandoned railroad moveable bridge spanning the Arkansas River, and the last bridge across the Arkansas River before it flows into the Mississippi River 15 miles to the southeast. It is distinctive not only for its size and remoteness, but also for having not one but two movable spans, one having replaced the other due to river avulsion. The Yancopin Bridge was originally constructed by the Memphis, Helena & Louisiana Railway, a wholly owned subsidiary of the St. Louis, Iron Mountain and Southern Railway that was known colloquially as Iron Mountain. The Iron Mountain itself became consolidated with the Missouri Pacific Railroad in 1881, but became fully merged later on in 1917. The single-track bridge is an all-metal truss bridge, designed with one lift span and with lengthy wooden trestle approaches at both ends. History The bridge was reportedly completed in 1903, but the track segment served by this bridge, between Watson and New Latour, was no ...

Watson, Arkansas
Watson is a city in Desha County, Arkansas, United States. The population was 211 at the 2010 census. Delta Heritage Trail In 1992, the Union Pacific Railroad discontinued service on a rail line which ran directly through Watson, and a right-of-way on which the rail line ran was donated to the State of Arkansas. Parts of the abandoned rail line have since been converted into the Delta Heritage Trail. The portion of the trail passing through Watson is still under construction. A wilderness lies to the north of the town, where the trail will have views of the Arkansas River (from the Yancopin Bridge), and of the White River (from the Benzal Bridge). Between the bridges, the trail is planned to traverse old-growth hardwood forest within the Trusten Holder State Wildlife Management Area. Geography According to the United States Census Bureau, the city has a total area of , all land. Demographics 2020 census As of the 2020 United States census, there were 185 people, 115 househ ...

Centralized Traffic Control
Centralized traffic control (CTC) is a form of railway signalling that originated in North America. CTC consolidates train routing decisions that were previously carried out by local signal operators or the train crews themselves. The system consists of a centralized train dispatcher's office that controls railroad interlockings and traffic flows in portions of the rail system designated as CTC territory. One hallmark of CTC is a control panel with a graphical depiction of the railroad. On this panel, the dispatcher can keep track of trains' locations across the territory that the dispatcher controls. Larger railroads may have multiple dispatcher's offices and even multiple dispatchers for each operating division. These offices are usually located near the busiest yards or stations, and their operational qualities can be compared to air traffic towers. Background Key to the concept of CTC is the notion of ''traffic control'' as it applies to railroads. Trains moving in opposite ...

Swing Bridges
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Railroad Bridges In Arkansas
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 faciliti ...
