Research and Development of Track System of High-Speed Railway

초록

The commercial operation of high speed train, KTX (Korea Train eXpress) started on April 1, 2004 in Korea. The Seoul-Busan corridor, known as Gyeongbu high speed line opened in 12 years of construction. During the period, the Korean high speed railway technology overcame many technical difficulties and acquired valuable experiences on construction and management of the infrastructures and train system. The knowledge from such trials were adapted and integrated to develop the next generation of KTX, which is a technically compatible system. Therefore, the G7 Project was launched in 1996, to trace and self-contain all high speed train technology ensuring its better performance and safety. In parallel with the development of the bullet train, successful results in track technology have been obtained, after the G7 high-speed railway technology development project was launched. Consequently, the research on the stabilization of the developed track system was performed by experimental research to ensure the safety and improve the performance of newly developed track system
