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 ...

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 ...

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. In 1945, after the Surrender of Japan, Japanese surrender at the End of World War II in Asia, end ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hochon Line
The Hŏch'ŏn Line is a partially electrified standard-gauge secondary line of the Korean State Railway running from Tanch'ŏn on the P'yŏngra Line to Honggun.Kokubu, Hayato, 将軍様の鉄道 (Shōgun-sama no Tetsudō), History The privately owned Tanp'ung Railway was formed to build a railway from Tanch'ŏn on the Hamgyŏng Line of the Chosen Government Railway to P'ungsan, the county seat of P'ungsan County; it was from the first characters of the names of the endpoints that the railway, and the mainline, got its name. The initial section of the mainline, from Tanch'ŏn to Honggun, was opened on 26 August 1939.朝鮮總督府官報 (The Public Journal of the Governor-General of Korea), Shōwa No. 3788, 4 September 1939 (in Japanese) A branchline, the Mandŏk Line, from Kosŏng (now called Hŏch'ŏn) to Mandŏk was also opened, but the planned continuation from Honggun to P'ungsan was not completed before the fall of Japan at the end of the Pacific War.

Overhead Line
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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-track Railway
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days, if the single track is not used for public passenger transit. Long freight trains are a problem if the passing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regional Rail
Regional rail, also known as local trains and stopping trains, are passenger rail services that operate between towns and cities. These trains operate with more stops over shorter distances than inter-city rail, but fewer stops and faster service than commuter rail. Regional rail services operate beyond the limits of urban areas, and either connect similarly-sized smaller cities and towns, or cities and surrounding towns, outside or at the outer rim of a suburban belt. Regional rail normally operates with an even service load throughout the day, although slightly increased services may be provided during rush-hour. The service is less oriented around bringing commuters to the urban centers, although this may generate part of the traffic on some systems. Other regional rail services operate between two large urban areas but make many intermediate stops. In North America, "regional rail" is not recognized as a service classification between "commuter rail" and "inter-city rai ...

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 ...

Danpung Railway
The Tanpō Railway (Japanese: 端豊鉄道株式会社, ''Tanpō Tetsudō Kabushiki Kaisha''; , ''Danpung Cheoldo Jusikhoesa''), was a privately owned railway company in Japanese-occupied Korea. History The name of the railway was formed from the first characters of the names of the starting point, Tansen on the Kankyō Line of the Chōsen Government Railway, and Hōzan, the county seat of Hōzan County. The initial section of the mainline, from Tansen to Kōkun, was opened on 26 August 1939.朝鮮總督府官報 (The Public Journal of the Governor-General of Korea), Shōwa No. 3788, 4 September 1939 (in Japanese) A branchline from Kojō (now called Heocheon) to Mantoku was also opened, but the planned continuation from Kōkun to Hōzan was not completed before the fall of Japan at the end of the Pacific War. Following the partition of Korea, the entirety of the Danpung Railway's network was located in the Soviet zone of occupation. The Provisional People’s Committee ...
