mageba – Project information Seoul–Busan High Speed Railroad (South Korea) Project description mageba scope Highlights & facts The Gyeongbu KTX (Korea Train Express) mageba supplied two RESTON®SA hydraulic between Seoul and Busan is South Korea’s dampers, each with a force capacity of mageba products: first high speed electric railway line and 1,500 kN and allowing movements of Type: RESTON®SA connects the north and south part of the ±100 mm (seismic design displacement hydraulic dampers country. Travellers from Seoul now reach ±30 mm). The dampers were designed Installation: 2016 Busan within less than 3 hours. according to the equation F = CVa, with Structure: C = 2,950 kN m/s, V = 0.259 m/s and α = 0.5 / 0.4. The high speed railway line has a total City: Daejeon length of 423.8 km. Four new stations As this type of bearings are velocity- Country: South Korea have been constructed to accommodate dependent devices, they primarily consist Type: High speed railway increased traffic between the regions and of a piston in a fluid-filled cylinder. bridge are set to open in conjunction with the Moreover, they allow free movements Completion: 2004 new line. of a structure during service conditions, Refurbishment: 2016 Top speed for trains in regular service but control displacements and dissipate Length: 423.8 km currently lies at 305 km/h (190 mph), energy during sudden movements caused, Owner: Korea Rail Network for example, by earthquakes or exceptional Authority though the infrastructure is designed to Contractor: Reflesh Construction traffic forces. reach speeds of 350 km/h (217 mph).
