  Abstract

For safe operation and maintenance of high-speed trains, precise train position detection is essential for accurate inspection of wayside facilities, such as track, catenary, and signaling equipment. Since GPS satellite signal is not available in tunnels, a railway transponder system is considered as a solution to solve the problem of error accumulation of wheel sensors and inertial sensors. In order to detect the exact location of the trains in a high-speed environment faster than 300km/h, communication between the transponder tag installed on the track and the transponder reader mounted beneath the train should be secured with high reliability and high availability. Based on the field test results conducted in the Honam high-speed line, we improved the communication performance of the railway transponder system. We then carried out field test in a high-speed condition up to 342.1km/h in order to validate the performance enhancement.
