A method for locating a rail vehicle along a rail route, along which a waveguide is laid. Temporally successive electromagnetic pulses are fed into the waveguide and, for each emitted pulse, at least one back-scattering pattern generated by vehicle-induced back-scattering of the electromagnetic pulse is received and evaluated. The waveguide has at least one locating section along the rail route, in which locating section the vibration sensitivity of the waveguide and/or the vibration acting on the waveguide is greater or less than outside the locating section. The amplitude of the received back-scattering pattern is evaluated and a location signal is generated if the amplitude of the received back-scattering pattern increases or decreases over the course of time.

Locating of vehicles

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.

Method and apparatus for locating rail vehicles

A method and an apparatus for operation of a railway branch line, which has line devices, in particular points, signals, axle counters, beacons and/or approach signaling devices, for specific functions. At least one first line device can be operated in an active mode and in a power-saving mode. In order to simplify the switching from the power-saving mode to the active mode, the active mode of the first line device is activated by a second line device when a rail vehicle moves over the second line device, possibly after a predetermined delay time has elapsed.
