Magnetic Flagman
Wigwag is a nickname for a type of railroad grade crossing signal once common in North America, referring to its pendulum-like motion that signaled the approach of a train. The device is generally credited to Albert Hunt, a mechanical engineer at Southern California's Pacific Electric (PE) interurban streetcar railroad, who invented it in 1909 for safer railroad grade crossings. The term should not be confused with its usage in Britain, where "wigwag" generally refers to alternate flashing lights, such as those found at modern level crossings. Rationale Soon after the advent of the automobile, travel speeds were increasing and the popularity of enclosed cars made the concept of "stop, look, and listen" at railroad crossings difficult. Fatalities at crossings were increasing. Though the idea of automatic grade crossing protection was not new, no one had invented a fail-safe, universally recognized system. In those days, many crossings were protected by a watchman who warned o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper River And Northwestern Railway
The Copper River and Northwestern Railway (CR&NW) consisted of two rail lines, the Copper River line and the Northwestern line. Michael James Heney had secured the right-of-way up the Copper River in 1904. He started building the railway from Cordova, Alaska in 1906. The town of Cordova, Alaska, was actually named by Heney on March 13, 1906, based on the original name given by Salvador Fidalgo. Both these railroads were abandoned and little remains of them. Only a 0-4-0 locomotive, "Ole", located near Goose City on a siding of the Alaska Anthracite Railroad Company is the only equipment left. Many of the holdings of the CR&NW railroad including Ole were acquired for this railroad by Mr. Clark Davis and his partners in 1908 after a major storm destroyed the Katalla area facilities in 1907. The town of Cordova would like to move Ole to a memorial site in Cordova to celebrate its role in these railroads. Ole was declared eligible for the National Register of Historic Places in ...

Winston-Salem Southbound Railway
The Winston-Salem Southbound Railway is a short-line railroad jointly owned by CSX Transportation and the Norfolk Southern Railway (NS), which provide it with equipment. It connects with NS at the north end in Winston-Salem, CSX at the south end in Wadesboro, and in between with NS at Lexington and Whitney, the subsidiary High Point, Thomasville and Denton Railroad at High Rock, and the Aberdeen, Carolina and Western Railway at Norwood. Originally owned jointly by the Atlantic Coast Line Railroad and Norfolk and Western Railway, predecessors to CSX and NS, it was completed in November 1910.Edward A. Lewis, American Shortline Railway Guide, 5th Edition, Kalmbach Publishing, 1996, pp. 149, 339 In 1957, the railroad retired its last steam locomotive in favor for diesel locomotion. In June 1960 the WSS acquired full control of the connecting High Point, Thomasville and Denton Railroad, which is similarly operated with equipment from both owners. Between 1913 and 1985 t ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Norfolk And Western Railway
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway to form today’s Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired between 1964 and 1965. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated of road on of track from North C ...

Union Pacific Railroad
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relay
A relay Electromechanical relay schematic showing a control coil, four pairs of normally open and one pair of normally closed contacts An automotive-style miniature relay with the dust cover taken off A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. The traditional form of a relay uses an electromagnet to c ...
