Abstract

1. Method for detecting landslip(s) on railway tracks, characterized in that the vibrations induced by the landlip(s) in at least one rail of the track are detected, the rail being used as the mechanical transducer and transmitter letting through preferentially at least one band of rail natural frequencies detected to set off an alarm signal system, and in that the detection system is neutralized each time a train passes.
