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 ...

Railway Lines In North Korea
North Korea has a railway system consisting of an extensive network of standard-gauge lines and a smaller network of narrow-gauge lines; the latter are to be found around the country, but the most important lines are in the northern part of the country. All railways in North Korea are operated by the state-owned Korean State Railway.Hayato, Kokubu, 将軍様の鉄道 (Shōgun-sama no Tetsudō), Lines whose names are in ''italics'' are closed.

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 ...

Kaechon Line
The Kaech'ŏn Line is an electrified standard-gauge secondary line of the Korean State Railway running from Sinanju on the P'yŏngŭi Line to Kaech'ŏn on the Manp'o Line. The ruling grade on the line is 14‰, the minimum curve radius is ; there are 14 bridges with a total length of , and there are four tunnels with a total length of . History The line was originally opened on 13 May 1916 by the Mitsui Mining Railway as a narrow-gauge line running from Sinanju to Kaech'ŏn. It was subsequently extended from Kaech'ŏn to Ch'ŏndong, with the new section being opened on 1 December 1918. In 1927, the company was renamed Kaech'ŏn Light Railway, and then was leased to the Chosen Government Railway (''Sentetsu'') on 1 November 1932. Sentetsu began converting the Kaech'ŏn–Ch'ŏndong section to standard gauge, completing this work on 15 July 1933,朝鮮総督府官報 (The Public Journal of the Governor-General of Korea), Shōwa No. 1947, 7 July 1933 (in Japanese) and on 1 Septe ...

Chunam River
Lime plaster is a type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime). Ancient lime plaster often contained horse hair for reinforcement and pozzolan additives to reduce the working time. Traditional non-hydraulic hydrated lime only sets through carbonatation when the plaster is kept moist and access of CO2 from the air is possible. It will not set when submersed in water. When a very thick layer or several layers are applied, the lime can remain soft for weeks. The curing time of lime plaster can be shortened by using (natural) hydraulic lime or adding pozzolan additives, transforming it into artificially hydraulic lime. In ancient times, Roman lime plaster incorporated pozzolanic volcanic ash; in modern times, fly ash is preferred. Non-hydraulic lime plaster can also be made to set faster by adding gypsum. Lime production for use in plastering home-made cisterns (in making them im ... [...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 collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

The Korean State Railway (), commonly called the State Rail () is the operating arm of the Ministry of Railways of North Korea and has its headquarters at P'yŏngyang. The current Minister of Railways is Chang Jun Song. History 1945–1953: Liberation, Partition, and the Korean War The railway lines of North Korea were originally built during the Japanese occupation of Korea by the Chosen Government Railway (''Sentetsu''), the South Manchuria Railway (''Mantetsu'') and various privately owned railway companies such as the Chosen Railway (''Chōtetsu''). At the end of the Pacific War, in the territory of today's North Korea Sentetsu owned of railway, of which was standard gauge, and was narrow gauge; in the same territory, privately owned railway companies owned of rail lines, of which was standard gauge and was narrow gauge.
