Bilevel Rail Car
A bilevel car (American English) or double-decker coach (British English and Canadian English) is a type of Passenger railroad car, rail car that has two levels of passenger accommodation as opposed to one, increasing passenger capacity (up to 57% per car in extreme cases). The use of double-decker carriages, where feasible, can resolve capacity problems on a railroad, avoiding other options which have an associated infrastructure cost such as longer trains (which require longer station platforms), more trains per hour (which the signalling or safety requirements may not allow) or adding extra tracks besides the existing line. Double deck trains are claimed to be more energy efficient, and may have a lower operating cost per passenger. A bi-level car may carry up to about twice as many as a normal car, if structure gauge, structure and loading gauges permit, without requiring double the weight to pull or material to build. However, a bi-level train may take longer to exchange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commuter Rail
Commuter rail or suburban rail is a Passenger train, passenger rail service that primarily operates within a metropolitan area, connecting Commuting, commuters to a Central business district, central city from adjacent suburbs or commuter towns. Commuter rail systems can use locomotive-hauled trains or multiple units, using electric or diesel propulsion. Distance charges or zone pricing may be used. The term can refer to systems with a wide variety of different features and service frequencies, but is often used in contrast to rapid transit or light rail. Some services share similarities with both commuter rail and high-frequency rapid transit; examples include German S-Bahn in some cities, the Réseau Express Régional (RER) in Paris, the Milan S Lines, S Lines in Milan, many Japanese commuter systems, the East Rail line in Hong Kong, and some Australasian suburban networks, such as Sydney Trains. Many commuter rail systems share tracks with other passenger services and Cargo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Platform Height
Railway platform height is the built height – ''above top of rail (ATR)'' – of railway platform, passenger platforms at railway station, 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 platforms 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 (transportation), dwell time as platform or staff are required to deploy ramps to assist boarding. Platform ramps, ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Tunnel
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline differs significantly from 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.Salazar, Waneta.

Bridge
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages. However, electrically powered single-unit railcars are also generally classed as EMUs. The vast majority of EMUs are passenger trains but versions also exist for carrying mail. EMUs are popular on intercity, commuter, and suburban rail networks around the world due to their fast acceleration and pollution-free operation, and are used on most rapid-transit systems. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting ...

El Capitan (train)
The ''El Capitan'' was a streamliner, streamlined passenger train operated by the Atchison, Topeka and Santa Fe Railway ("Santa Fe") between Chicago, Illinois, and Los Angeles, California. It operated from 1938 to 1971; Amtrak retained the name until 1973. The ''El Capitan'' was the only all-coach or "chair car" (non-Pullman (car or coach), Pullman sleeper) to operate on the Santa Fe main line between Chicago and Los Angeles on the same fast schedule as the railroad's premier all-Pullman ''Super Chief''. It was also the first train to receive the pioneering Hi-Level equipment with which it would become synonymous. History The ''El Capitan'' debuted on February 22, 1938, on a twice-weekly schedule, using two five-car sets of streamliner, streamlined equipment built by the Budd Company. Like the Pennsylvania Railroad's ''Trail Blazer (passenger train), Trail Blazer'', it offered "low-cost passage with high-speed convenience". The fare from Chicago to Los Angeles was $5.00 a ...
