Summary
This paper summarizes a track condition monitoring system using on-board sensing device for conventional railway. Track irregularities are estimated from a vertical and lateral acceleration and roll rate of a car body. Rail corrugation is detected from cabin noise with spectral peak calculation. A GPS system and a map-matching algorithm are used to pinpoint the location of faults on tracks. A new device is developed to give higher performance for practical use. Collected data are kept in an inside memory or transferred to a data server via cellular phone. The track condition monitoring system using the compact size on-board devices provide regular monitoring of tracks for sustaining railway system with securing safety.
