Ballastless track technology ballastless track on Korean high-speed railway

The Seoul-Busan high-speed railway in South Korea has a total length of 4 12km and will be built in two phases. The first phase is from Seoul to Daegu, with a total length of 289.3km, and the second phase is from Daegu to the south section of Busan, with a total length of 122.7km. In the first phase, 53.438+0 km ballastless track is laid in Guangming Station and three tunnels in Zhang Shang, Huaxin and Huanghe, mainly using German common radar ballastless track. The second phase of the project started in June 2002 and is expected to be completed in February 20 10. It is planned to lay all radar 2000 ballastless tracks.

At present, Rheda double-block track (Germany), Zublin double-block track (Germany), Bogl slab track (Germany) and Japanese slab track are widely used in the construction of ballastless track in Korean railways.
