Evaluation of track performance corresponding to 350km/h speed increase of HSR

한국형 고속열차 350km/h 증속에 따른 궤도성능평가

For the Korean high speed railway rolling stock, which is developed through the G7 research project, various tests such as components test, prototype train test, on-line test have been carried out for years. In order to obtain the system stability, mutual interface between each part (rolling stock, track, bridge, electricity and signal) should be verified. For this reason, track performance according to the speed increase of HSR has been monitored in field. Especially, through the analyses of accumulated data, structural and running stability of HSR has been evaluated. With this viewpoint, this paper presents the track performance test method and the test results corresponding to 350km/h speed increase of HSR.
