摘要： A method for locating a rail vehicle with a rail vehicle position determination device on a route includes reading positions of reference marks, passed by the rail vehicle, along the route of the rail vehicle and evaluating additional distance information. In order to locate a rail vehicle with little expenditure and with comparatively high accuracy, in the case of a route with at least one track section bounded by axle counting sensor units and having an axle counting evaluator, information on the number of axles from the axle counting evaluator is transferred to the rail vehicle position determination device for determining the position of a rail vehicle. In the rail vehicle position determination device, the position of an axle of the rail vehicle corresponding to the information on the number of axles is determined using route topology data present there, and this position is used as a further reference mark.

摘要： A method and apparatus to detect breaks in tracks and/or detect the presence of a vehicle, such as a train, in a monitored section of the track or rail. Embodiments of the present invention measure the change in track inductance associated with a track or rail break. Electrical shunts are connected between the rails at spaced-apart intervals (for example a shunt can be placed every mile). At least two different frequencies of alternating current are generated and fed into the segments of rail (for example at or near a mid-point between the shunts). If a rail break occurs, the total inductance of the rail at that segment will change. Using two or more frequencies allows a rail break to be differentiated from environmental rail-to-rail and rail-to-earth leakage.

摘要： A fastening device for fastening at least one sensor to a railway rail includes at least one clamping bow and at least two mutually opposite clamping regions connected to the clamping bow. The at least one sensor and at least part of the railway rail can be disposed between the clamping regions. At least one clamping device is connected to the clamping bow for applying the clamping force between the clamping regions for fastening the at least one sensor to the railway rail. A sensor arrangement including the fastening device and a method for fastening at least one sensor to a railway rail are also provided.
