Magnetic Levitation train (Maglev) lines built. These new lines need ... between Seoul and Pusan in South Korea, which is planned to have 75 tunnels ...

The design of new high-speed railway lines requires longer and more numerous tunnel sections, where aerodynamic effects limit the maximum allowed train velocity for a given tunnel cross-section area. These effects influence the train power requirement, the traction energy costs and the pressure wave amplitude: the knowledge of the unsteady aerodynamic field around the train is therefore essential to the optimum choice of a tunnel configuration, and mainly of the cross-section diameter and of the presence and position of pressure relief ducts. The aerodynamic phenomena generated by a train traveling at high speed through a long tunnel of small cross-section are analyzed by means of quasi one-dimensional numerical simulations of the air flow induced by a train traveling at 120 m/s in a tunnel connecting two stations 60 km apart. Several tunnel configurations at high blockage ratio are discussed, together with the positive and negative effects of pressure relief ducts and of partial air vacuum. Aerodynamic phenomena are evaluated in terms of drag, pressure wave amplitude and shock wave onset on the train tail. Results suggest that configurations consisting of twin tunnels connected by pressure relief ducts near stations and operated under partial vacuum should be preferred.

Korea Maglev project update ...

The nation encompasses 98,480 square kilometers (the Korean peninsula is 219,020 sq. km.), and in 2003, boasted a population of 48.5 million. In terms of population density, Korea currently ranks 11th in the world. Mountainous areas occupy more than 70% of the land. Its neighbors include China (population: 1.3 billion), and Japan (population: 130 million), which rank among the larger countries of the world. Korea could well become a center for logistics, connecting huge markets, if it can improve its infrastructure— including higher-capacity ports and airports—and management to better accommodate passengers and freight from neighboring countries.

Currently, Korea’s railway network extends 3,125 kilometers and, due to rapid motorization and urbanization across the country over the last four decades, it also possesses a relatively extensive highway network of 86,900 kilometers. While no new rail lines have been added since 1945 (when the country achieved independence from Japanese colonial rule), the road network has expanded at an enormous rate

KRRI ventures into Maglev train project

Korea Railroad Research Institute ( KRRI ) set out to come up with research plans to commercialize the MagLev(Magnetic Levitation) train system and embarked on focused research activities in October 2004.

Chosen as one of the "top thirty National Innovation Systems" for the public use on the national level, the MagLev train project is now emerging to rub shoulders with the KRRI's flagship project Korea High Speed Train in its critical value.

China successfully put magnet-driven trains on track for the public when Korea has been shy of momentum to put them to commercial use. As things stand, KRRI has set out to conduct research aimed at bringing forward the MagLev commercialization project based on its localized technologies.

On this note, leader of  MagLev system research team Young-hoon Lee had an eight-day tour to Germany, China and Japan in September for MagLev rides and system investigations. Back to work, he hosted a meeting to share his view and ideas on the MagLev technology flow with outside attendees present from Rotem, kwangju Metropolitan Subway Corporation, Korea Rail Network Authority.

He also met with researchers from Korea Institute of Machinery and Materials in an attempt to seek cooperative measures over the course of the forthcoming national project

Maglev Train Line for Seoul Proposed.

A magnetic levitation train line linking a futuristic international business district in downtown Seoul with a new urban development project in the city’s outskirts has been proposed, industry sources said Sunday ( Feb. 17 2008 ).

Samsung Corp., the head of the consortium that is moving to rebuild part of Seoul’s Yongsan district by injecting 28-trillion won ($29.6 billion) into the area, said the train line proposal has been submitted to the Seoul Metropolitan government for approval.

The Yongsan project is the largest urban development project to date in the country, and calls for a 152-story office tower and residential apartments that can be transformed into an international business hub.

The company said building the magnetic levitation trains, called maglevs, could greatly ease traffic congestion and open new horizons for urban transportation.

Under the plan, the maglev train track will be laid from the Songpa district in the city’s southeast, where a large residential area is being developed, to the Gangnam district and then Yongsan, just north of the Han River.

Samsung said construction on the train line could begin in 2010 for completion in 2013. The total cost is estimated at 840 billion won, with Samsung consortium funding 60 percent of the expense.

The remainder, the company said, could be paid by Seoul and the central government.

Maglevs use a technology that propels trains at very high speeds over magnetically charged tracks, allowing trains to float on top of electromagnets.

Two Main Corridors

 

Korea has two main transport corridors and much of the country’s development has occurred along them. The Seoul–Busan corridor runs southeast from Seoul. Over 70% of the population resides along the corridor, and over 70% of the nation’s GDP is produced along it. In addition, about two-thirds of passenger trips and 70% of all cargo trips originate there, since most of the nation’s industrialization and urbanization has been concentrated along this axis. The other corridor, Seoul–Mokpo, runs southwest from Seoul. More farming areas lie along

this route and, hence, lighter travel demand.

Seoul to Pusan..
 

The Korean Maglev Line between Seoul and Pusan is linking the major economic and cultural centers of Korea. The line has intermediate stations and consists of 510 km track, including 27% of at-grade sections, 27% of viaducts and  46% of tunnels . The commercial speed will be 300 km/h and the traveling time 1hr 56 minutes between the two terminal stations. The daily transport of passengers is estimated 520,000. The annual tonnage amounts to about 60 MGT.
