METHOD AND SYSTEM FOR MONITORING A TRACK LINE

A method for monitoring a track line by way of a monitoring device which is connected to a sensor extending along the track line. The sensor which is set in vibration delivers measurement data for the monitoring device. A rail vehicle travels on the track line, during which vibrations having known vibration values are introduced into the track line and transmitted to the sensor. Position data of the rail vehicle are recorded and an evaluation device derives a characteristic of the vibration transmission from the vibration values, the position data, and the measurement data for the track line. In this manner, a calibration of the system takes place with only a single run on the track line.
