Train Order Operation
A train order is "an order issued by or through a proper railway official to govern the movement of trains". Train order operation is the system by which trains are safely moved by train orders. It is distinguished from other forms of train operation in which the authority to move trains is given by fixed signals or Cab signalling. Train order operation, or more accurately timetable and train order operation, was the standard operational system used by the railroads of North America before the days of centralized traffic control, direct traffic control, and the use of track warrants conveyed by radio. The system used a set of rules when direct communication between train dispatchers and trains was limited or non-existent. Trains would follow a predetermined operating plan, known as the timetable, unless superseded by train orders conveyed to the train from the dispatcher, through local intermediaries. Train order operation was a system that required minimum human overhead in an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isleta Order Hoops
Pueblo of Isleta ( tix, Shiewhibak , kjq, Dîiw'a'ane ; nv, Naatoohó ) is an unincorporated community and Tanoan pueblo in Bernalillo County, New Mexico, United States, originally established in the . The Southern Tiwa name of the pueblo is (Shee-eh-whíb-bak) meaning "a knife laid on the ground to play ''whib",'' a traditional footrace. Its people are a federally recognized tribe. Pueblo of Isleta is located in the Middle Rio Grande Valley, south of Albuquerque. It is adjacent to and east of the main section of Laguna Pueblo. The pueblo was built on a knife-shaped reef of lava running across an ancient Rio Grande channel. The Isleta Pueblo Historic District is listed on the National Register of Historic Places. On January 15, 2016, the tribe's officials and federal government representatives held a ceremony to mark the government's taking into federal trust some 90,151 acres of land (140 square miles) which the Pueblo had then purchased. It enlarged their communal ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right-of-way (traffic)
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or traffic sign, signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate. O ...

Rail Yard
A rail yard, railway yard, railroad yard (US) or simply yard, is a series of tracks in a rail network for storing, sorting, or loading and unloading rail vehicles and locomotives. Yards have many tracks in parallel for keeping rolling stock or unused locomotives stored off the main line, so that they do not obstruct the flow of traffic. Cars or wagons are moved around by specially designed yard switchers (US) or shunters, a type of locomotive. Cars or wagons in a yard may be sorted by numerous categories, including railway company, loaded or unloaded, destination, car type, or whether they need repairs. Yards are normally built where there is a need to store rail vehicles while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations. Many yards are located at strategic points on a main line. Main-line yards are often composed of an up yard and a down yard, linked to the associated direction of travel. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onionskin
Onionskin or onion skin is a thin, lightweight, strong, often translucent paper. Though not made from onions, it superficially resembles their thin, papery skins. It was usually used with carbon paper for typing duplicates in a typewriter, for permanent records where low bulk was important, or for airmail correspondence. It is typically 25–39 g/m2 (9-pound basis weight in US units), and may be white or canary-colored. In the typewriter era, onion skin often had a deeply textured cockle finish which allowed for easier erasure of typing mistakes, but other glazed and unglazed finishes were also available then and may be more common today. Onionskin paper is relatively durable and lightweight due to its high content of cotton fibers. Because of these attributes and its crispness when folding, onionskin paper is one of the best papers to use for toy kites and advanced paper airplanes. Paper airplanes made from onionskin paper tend to fly very well due to their low weight a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Station
A train station, railway station, railroad station or depot is a railway facility where trains stop to load or unload passengers, freight or both. It generally consists of at least one platform, one track and a station building providing such ancillary services as ticket sales, waiting rooms and baggage/freight service. If a station is on a single-track line, it often has a passing loop to facilitate traffic movements. Places at which passengers only occasionally board or leave a train, sometimes consisting of a short platform and a waiting shed but sometimes indicated by no more than a sign, are variously referred to as "stops", "flag stops", " halts", or "provisional stopping places". The stations themselves may be at ground level, underground or elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems. Terminology In British English, traditional terminology favours ''railway station' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Siding
A siding, in rail terminology, is a low-speed track section distinct from a running line or through route such as a main line, branch line, or spur. It may connect to through track or to other sidings at either end. Sidings often have lighter rails, meant for lower speed or less heavy traffic, and few, if any, signals. Sidings connected at both ends to a running line are commonly known as loops; those not so connected may be referred to as single-ended or dead-end sidings, or (if short) stubs. Functions Sidings may be used for marshalling (classifying), stabling, storing, loading, and unloading vehicles. Common sidings store stationary rolling stock, especially for loading and unloading. Industrial sidings (also known as spurs) go to factories, mines, quarries, wharves, warehouses, some of them are essentially links to industrial railways. Such sidings can sometimes be found at stations for public use; in American usage these are referred to as team tracks (after the use ...

Track Warrant Control
A track warrant is a set of instructions issued to a train crew authorizing specific train movements. The system is widely used in North America. The warrant is issued by the train dispatcher and delivered to the train crew via radio. The train crew copies the instructions onto a pre-printed paper form and reads back the warrant to ensure that nothing was misunderstood. Operation Track warrants are issued granting main track use between two named points (i.e. milepost sign, station, and/or any fixed physical point, such as a switch). The dispatcher may also issue time constraints (known as "Box 6" on a standard form), although the track warrants remain in effect until cleared by a member of the receiving crew. Track warrants are sometimes used in conjunction with a block signal system to provide rear-end protection against following trains. Track warrants usually allow a train to move in one direction only—a "Proceed" instruction. Sometimes a train may also be given authorizing ...
