Passenger Rail Terminology
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas: Rapid transit A rapid transit system is an electric railway characterized by high speed (~) and rapid acceleration. It uses passenger railcars operating singly or in multiple unit trains on fixed rails. It operates on separate rights-of-way from which all other vehicular and foot traffic are excluded (i.e. is fully grade-separated from other traffic). It uses sophisticated signaling systems, and high platform loading. Originally, the term ''rapid transit'' was used in the 1800s to describe new forms of quick urban public transportation that had a right-of-way separated from street traffic. This set rapid transit apart from horsecars, trams, streetcars, omnibuses, and other forms of public transport. A variant of the term, ''mass rapid transit (MRT)'', is also used for metro systems in Southeast Asia and Taiwan. Though the term was almost alway ...

Refractory
In materials science, a refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, non-metallic, porous, and heterogeneous. They are typically composed of oxides or carbides, nitrides etc. of the following materials: silicon, aluminium, magnesium, calcium, boron, chromium and zirconium. ASTM C71 defines refractories as "...non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above ." Refractory materials are used in furnaces, kilns, incinerators, and reactors. Refractories are also used to make crucibles and moulds for casting glass and metals and for surfacing flame deflector systems for rocket launch structures. Today, the iron- and steel-industry and metal casting sectors use appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japanese Government Railways
The Japanese Government Railways (JGR) was the national railway system directly operated by the Japanese Ministry of Railways ( ja, 鉄道省, Tetsudō-shō, ) until 1949. It was a predecessor of Japanese National Railways and the later Japan Railways Group. Name The English name "Japanese Government Railways" was what the Ministry of Railways (established in 1920) used to call its own and sometimes the ministry itself as a railway operator. Other English names for the government railways include Imperial Japanese Government Railways and Imperial Government Railways, which were mainly used prior to the establishment of the ministry. This article covers the railways operated by the central government of Japan from 1872 to 1949 notwithstanding the official English name of the system of each era. Network By the end of World War II in 1945, the Japanese Government Railways operated on the main Japanese islands of Honshū, Hokkaidō, Kyūshū, Shikoku and Karafuto. The railways ...

Railway
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 facilit ...

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] |
