Abstract
A method for operating a locating device having a waveguide laid along a stretch of track to locate a rail vehicle on the stretch of track includes injecting electromagnetic pulses into the waveguide in succession or series and receiving and evaluating backscattering patterns produced by backscattering of the electromagnetic pulse for each emitted pulse. A vibration device located in the region of the stretch of track at a known position is activated at a predefined activation time and a vibration causing backscattering of the electromagnetic pulse is thereby produced at the known position, the duration between the activation time and the receipt of the backscattering pattern indicating the vibration is measured, and the measured duration is used to check the functionality or operation of the locating device or to calibrate the locating device. A locating apparatus for locating a rail vehicle along a stretch of track is also provided.
