Abstract

In Korea, when a running train passes a turnout, the operating speed is limited to a lower level than that on a general track; the reason is to prevent safety accidents when a train is running. An empirical study was conducted on electronic multiple unit (EMU) trains in operation to examine the possibility of increasing the speed of trains on existing tracks. After the train speed increase test in certain sections of the Honam and Gyeongbu lines, the results were considered to examine the possibility of speed increase. The safety for increasing speed was evaluated based on the UIC 518 safety simplified method after measuring the vibration acceleration.
