In Korea, Korean Train Express (KTX) was opened to commercial traffic 3years ago. Korea High-speed Railway (HSR 350x) was developed and succeeded 350km/h test run by Korean government and several related institute. With the increase of the speed, the vibration control of the high-speed railway becomes important to improve high ride quality. To meet this request, the authors suggest the installation of lateral semi-active damper to the power car of HSR 350x. The result shows better performance.
