  • The guideline for railway noise mapping is notificated in the administration law for noise/vibration which is announced by the ministry of environment, Korea. Here input parameters for the railway sound sources are proposed for each prediction models. In case of the application of the vehicle characteristics it is suggested to choose "0(%)" for the disc brake parameter. However new trains have been in revenue service since the announcement of the guideline, an investigation of the effect of the input parameters of the foreign railway prediction models on the prediction results of korean railway systems are needed. In this paper the sound prediction results are analyzed with a focus on the input parameters such as disc brake percentage, rail roughness, rail joints. Schall03 is used for the railway noise prediction which has been using most frequently in Korea. The results are shown and discussed.

  • Recently, the ride comfort problem becomes increasingly important because of today's needs for train speedup. The railway has the track irregularities which cause vibrations, such as rail joints, turnout, level crossing, transition corves and super-elevation ramps, and variations in the track level(z-axis) and the gauge(y-axis). In Korea, the service run of the high speed train has been made since the 1st of April, 2004. The commercial high-speed trains must be run on the compound lines which are composed of high-speed line and conventional line. The high speed lines in both Kyoungbu line and Honam line have 57.5％ and 33.8％, respectively In this Paper, the ride comfort has been reviewed by the various experimental methods when the high-speed trains are operated on both Kyoungbu line and Honam line. The results show that the high-speed train has no problems from the viewpoint of the comfort ride during the operation on the high speed line and conventional line.
