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 ...

North Korea
North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korea, Korean Peninsula and shares borders with China and Russia to the north, at the Yalu River, Yalu (Amnok) and Tumen River, Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone. North Korea's border with South Korea is a disputed border as both countries claim the entirety of the Korean Peninsula. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like South Korea, its southern counterpart, claims to be the legitimate government of the entire peninsula and List of islands of North Korea, adjacent islands. Pyongyang is the capital and largest city. In 1910, Korean Empire, Korea was Korea under Japanese rule, annexed by the Empire of Japan.

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 ...

Chongchon River
The Ch'ŏngch'ŏn is a river of North Korea having its source in the Rangrim Mountains of Chagang Province and emptying into the Yellow Sea at Sinanju. The river flows past Myohyang-san and through the city of Anju, South P'yŏngan Province. Its total length is 217 km (135 mi), and it drains a basin of 9,553 km2 (3,688 sq mi). Important Bird Area The river's estuary has been identified by BirdLife International as an 8000 ha (19,768 acre) Important Bird Area (IBA) because it supports significant numbers of the populations of various bird species. These include swan geese, bean geese, whooper swans, Oriental storks, black-faced spoonbills, Chinese egrets, great bustards, white-naped cranes, hooded cranes, red-crowned cranes, Far Eastern curlews and spotted greenshanks. The site includes the 800 ha (1,977 acre) Mundok Nature Reserve. Hydroelectric dams North Korea is building 10 new hydroelectric dams on the Chongchon River to spur rapid ...

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] |
Kujang County
Kujang County is a ''kun'', or county, in southeastern North P'yŏngan province, North Korea. It was created in 1952 from part of Nyŏngbyŏn county, as part of a nationwide reorganization of local government. It borders Nyŏngbyŏn on the west, Hyangsan and Unsan counties on the north, Nyŏngwŏn on the east, and Kaech'ŏn and Tŏkch'ŏn cities to the south. Geography The Myohyang Mountains stretch across the eastern part of Kujang. The highest point is Kalbong (칼봉, 1530 m) in the north. The Ch'ŏngch'ŏn River flows through the centre of the county, and the Kuryong River flows along its western flank. Due to the mountainous terrain, only 17% of the county's land is cultivated, while 74% is occupied by forestland. Administrative divisions Kujang county is divided into 1 '' ŭp'' (town), 5 '' rodongjagu'' (workers' districts) and 22 '' ri'' (villages): Climate The average annual temperature is 8.4 °C, with a January mean of -10.4 °C and an August mea ...

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 ...

Korean State Railway
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. At the same time, in September 1945 in the future territory of the DPRK there were 678 locomotives (124 steam tank, 446 tender, 99 narrow ...
