Xochimilco Light Rail
The Xochimilco Light Rail (locally known as el Tren Ligero and known by the government as Tren ligero de la Ciudad de México) is a light rail line that serves the southern part of Mexico City. It connects to, but is not considered a part of, the Mexico City Metro. Rather, it is operated by the ''Servicio de Transportes Eléctricos'' (STE), the authority that operates Mexico City's electric trolleybus system and formerly operated the municipal electric tram system. History Many of Mexico City's original tram lines were abandoned in the 1960s and 1970s. The original Xochimilco tramline had been in operation since 1910, but the Xochimilco tramway's section between Avenida Tasqueña and the city centre was replaced by a new metro line in 1970.Morrison, Allen (2003)The Tramways of Mexico City, Part 4.Retrieved 2010-05-05.May, Jack (1994).

Vehicle Propulsion
Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. The term is derived from two Latin words: ''pro'', meaning'' before'' or ''forward''; and '' pellere'', meaning ''to drive''. A propulsion system consists of a source of mechanical power, and a ''propulsor'' (means of converting this power into propulsive force). Plucking a guitar string to induce a vibratory translation is technically a form of propulsion of the guitar string; this is not commonly depicted in this vocabulary, even though human muscles are considered to propel the fingertips. The motion of an object moving through a gravitational field is affected by the field, and within some frames of reference physicists speak of the gravitational field generating a force upon the object, but for deep theoretic reasons, physicists now consider the curved ...

Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. ...

PCC Streetcar
The PCC (Presidents' Conference Committee) is a streetcar (tram) design that was first built in the United States in the 1930s. The design proved successful in its native country, and after World War II it was licensed for use elsewhere in the world where PCC based cars were made. The PCC car has proved to be a long-lasting icon of streetcar design, and many remain in service around the world. Origins The "PCC" initialism originated from the design committee formed in 1929 as the "Presidents' Conference Committee", renamed the "Electric Railway Presidents' Conference Committee" (ERPCC) in 1931. The group's membership consisted primarily of representatives of several large operators of U.S. urban electric street railways plus potential manufacturers. Three interurban lines and at least one "heavy rail", or rapid transit, operator—Chicago Rapid Transit Company—were represented as well. Also included on the membership roll were manufacturers of surface cars ( streetcars) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 collector ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fare
A fare is the fee paid by a passenger for use of a public transport system: rail, bus, taxi, etc. In the case of air transport, the term airfare is often used. Fare structure is the system set up to determine how much is to be paid by various passengers using a transit vehicle at any given time. A linked trip is a trip from the origin to the destination on the transit system. Even if a passenger must make several transfers during a journey, the trip is counted as one linked trip on the system. Uses The fare paid is a contribution to the operational costs of the transport system involved, either partial (as is frequently the case with publicly supported systems) or total. The portion of operating costs covered by fares - the farebox recovery ratio - typically varies from 30%-60% in North America and Europe, with some rail systems in Asia over 100%. The rules regarding how and when fares are to be paid and for how long they remain valid are many and varied. Where the fare can g ...

Paid Area
In rail transport, the paid area is a dedicated "inner" zone in a railway station or metro station, accessible via turnstiles or other barriers, to get into which, visitors or passengers require a valid ticket, checked smartcard or a pass. A system using paid areas is often called fare control. Passengers are allowed to enter or exit only through a faregate. A paid area usually exists in rapid transit railway stations for separating the train platform from the station exit, ensuring a passenger has paid or prepaid before reaching the railway platform and using any transport service. Such design requires a well-organized railway station layout. In some systems, paid areas are named differently - for example, on railways in the United Kingdom they are called compulsory ticket areas The paid area is similar in concept to the airside at an airport. However, in most cases entrance to the paid area requires only a valid ticket or transit pass. The exception is in certain cases of inte ...

Railway Platform
A railway platform is an area alongside a railway track providing convenient access to trains. Almost all stations have some form of platform, with larger stations having multiple platforms. The world's longest station platform is at Hubbali Junction in India at .Gorakhpur gets world's largest railway platform ''The Times of India'' The Appalachian Trail station in the United States, at the other extreme, has a platform which is only long enough for a single bench. Among some United States train conductors the word "platform" has entered [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Platform Height
Railway platform height is the built height – ''above top of rail (ATR)'' – of passenger platforms at stations. A connected term is ''train floor height'', which refers to the ATR height of the floor of rail vehicles. Worldwide, there are many, frequently incompatible, standards for platform heights and train floor heights. Where raised platforms are in use, train widths must also be compatible, in order to avoid both large gaps between platform and trains and mechanical interference liable to cause equipment damage. Differences in platform height (and platform gap) can pose a risk for passenger safety. Differences between platform height and train floor height may also make boarding much more difficult, or impossible, for wheelchair-using passengers and people with other mobility impairments, increasing station dwell time as platform or staff are required to deploy ramps to assist boarding. Platform ramps, steps, and platform gap fillers together with hazard warnings suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
