기존선 속도향상을 위한 기술적 검토

초록

With speed-up of existing railway, a greater attention is paid to the riding safety and the comfort of the passengers. They are combined to some technical factors related to track such as alignment, derailment coefficient, and track bearing capacity. A quarititative analysis method for those technical factors is presented in this study. Calculating the allowable transit speed, the technical reviews of speed-up of Janghang-Line are conducted. And the alternatives for improving train speed in existing railway are proposed.
