    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.

    Abstract: A method for measuring a vehicle moving on a roadway, in particular a bridge, by means of at least one sensor measuring the deformation under load of the roadway includes recording the time curve of the sensor-measured value while the vehicle moves past the sensor; repeating a minimization, in which a measure of the deviation from the recorded curve by a parametrized reference function comprising a sum of a number of rational functions is minimized by adapting the parameters thereof, wherein a different number is used in every repetition and, in fact, as often as necessary until the deviation measure falls below a limit value, and then selecting the reference function associated with this deviation measure as the selected reference function; and determining the number of rational functions of the selected reference function as the number of axles of the vehicle.

    Abstract: A railway track circuit system utilizing an optical sensor which emits a vehicle detection light signal when a railway vehicle is present in a track section. A reference light signal is also generated by a light emission source. A detector in optical communication with the optical sensor receives the vehicle detection light signal. Information contained in the vehicle detection light signal is interpreted by a processor to detect the railway vehicle. In presently preferred embodiments, the sensor may comprise an elongated optical fiber conductor extending along the track section or a plurality of cascaded localized sensors. The sensor may generally also be utilized as a communication medium to pass communication data between opposite ends of the track section. Depending on the exigencies of the particular application, the sensor may be located within the track section in a number of ways.
