Transportation In South Korea
Transportation in South Korea is provided by extensive networks of railways, highways, bus routes, ferry services and air routes that traverse the country. South Korea is the third country in the world to operate a maglev train, which was an automatically run people mover at Incheon International Airport. History Development of modern infrastructure began with the first Five-Year Development Plan (1962–66), which included the construction of 275 kilometers of railways and several small highway projects. Construction of the Gyeongbu Expressway, which connects the two major cities of Seoul and Busan, was completed on 7 July 1970. In 1970, around half of the population of Seoul, one of South Korea's most industrial cities, had moved to it only in the prior decade. With the rapid increase of people traveling across the country, a means of transporting large groups of people was needed. Public transportation, such as trams and railways, was installed for these people to move quickly. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pollutant
A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts). Pollutants result in environmental pollution or become of public health concern when they reach a concentration high enough to have significant negative impacts. A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with resources used by humans, human health or wellbeing, or property values. Some pollutants are biodegradable and therefore will not persist in the environment in a long term. However, the degradation products of some pollutants are themselves pollutants such as DDE and DDD produced from the degradation of DDT. Pollution has widespread negative impact on the environment.

Mugunghwa-ho
The Mugunghwa-ho () is a class of train operated by Korail, the main railway operator of South Korea. Mugunghwa trains are Korail's slowest tier of trains stopping at a number of towns and villages, and operating over a number of lines that are not served by other trains. Journey times are generally twice that of KTX trains and 25% longer than ITX express trains. Along rural lines such as the Gyeongbuk Line, Mugunghwa-ho remain the only class of passenger train operating. They (and in some cases the Tonggeun) are the only trains to stop at many stations not served by Saemaeul-ho or KTX trains. Mugunghwa are built to accommodate large numbers of standing passengers, and frequently have many more standees than sitting passengers during high season. History In 1980, new express train, named Udeung (우등, literally meaning Premium), was introduced. It was renamed Mugunghwa-ho, which was the name of an express train formerly operating in the 1960s. Today, all long-dist ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

ITX-Saemaeul
The Intercity Train eXpress-Saemaeul (ITX-Saemaeul; ) is a class of train operated by Korail, the national railroad of South Korea, it was introduced on May 12, 2014, to replace the Saemaeul-ho. The new ITX-Saemaeul trains have a faster average speed of 150 kilometers per hour. The name was taken from the Saemaul Undong after a public competition to determine the new train's name.

Korea Rail Network Authority
Korea National Railway is a railroad construction and management company in South Korea formed by the merger of KNR Construction Headquarters and Korean Express Railroad Construction Corporation. Its main clients are Korail. It is a subsidiary of the Ministry of Land, Infrastructure and Transport. Korea National Railway was established as the ''Korean National Railroad Administration'' by the Korea National Railway Act. History During the early 2000s, the South Korean government decided to split the national railroad into separate companies for operation and construction. Consequently, the Korean National Railroad was broken up into Korail (established in January 2004) and Korea Rail Network Authority (established in January 2005 and renamed to Korea National Railway in September 2020), the former managing train operations while the latter maintains the railway infrastructure. Amongst other benefits, this change was promoted as permitting open access across the Korean railwa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Korail
The Korea Railroad Corporation () is the national railway operator in South Korea. It is branded as KORAIL () and changed its official Korean name () in November 2019. Currently, KORAIL is a public corporation, managed by Ministry of Land, Infrastructure and Transportation. KORAIL operates intercity/regional, commuter/metro and freight trains throughout South Korea, and has its headquarters in Daejeon. History Historically, the South Korean railway network was managed by the ''Railroad Administration Bureau'' of the Ministry of Transportation before 1963. On 1 September 1963, the bureau became an agency that was known as ''Korean National Railroad'' (KNR) in English. In the early 2000s, the split and public corporatization of KNR was decided by the South Korean government, and in 2003, KNR adopted the current KORAIL logo in blue to prepare for corporatization. On 1 January 2005, KNR was split into ''Korea Railroad Corporation'' (KORAIL), which succeeded railway operati ...

KTX-I
The KTX-I, also known as the TGV-K or Korail Class 100000, is a South Korean high speed train class based on the French TGV Réseau. The 20-car formation of the trainsets without a restaurant car is optimized for high capacity. The 46 trainsets were built partly in France and partly in South Korea in the framework of a technology transfer agreement, which was the basis for further domestic high-speed train development in South Korea. Korail uses the name of KTX as the official name of KTX-I. The name of KTX-I is derived to distinguish KTX-Sancheon, which was formerly called as KTX-II, but it is not the official name for this rolling stock. The high-speed rail service of South Korea's national rail carrier Korail, Korea Train Express (KTX), started with the KTX-I. The operational reliability of the trains was improved over time with better maintenance and minor modifications. As of 2011, the KTX-I remains Korail's main workhorse in KTX service with a maximum scheduled speed of ...

Electrification
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. In the context of history of technology and economic development, electrification refers to the build-out of the electricity generation and electric power distribution systems. In the context of sustainable energy, electrification refers to the build-out of super grids and smart grids with distributed energy resources (such as energy storage) to accommodate the energy transition to renewable energy and the switch of end-uses to electricity. The electrification of particular sectors of the economy, particularly out of context, is called by modified terms such as Mass production#Factory electrification, ''factory electrification'', ''household electrification'', ''rural electrification'' and ''railway electrification''. In the context of sustainable energy, terms such as ''transport electrification'' (referring to electric v ...

Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a colorless gas with a pungent smell that is responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of metals refining and the burning of Sour gas, sulfur-Sour crude oil, bearing fossil fuels. Sulfur dioxide is somewhat toxic to humans, although only when inhaled in relatively large quantities for a period of several minutes or more. It was known to medieval alchemy, alchemists as "volatile spirit of sulfur". Structure and bonding SO2 is a bent molecule with ''C''2v Point groups in three dimensions, symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance (chemistry), resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
