A method for operating a railroad crossing includes using an axle counter to capture measurement data for rail vehicles approaching the railroad crossing during passage of the rail vehicle. The velocity and the acceleration of the rail vehicle are calculated from the measurement data as properties of the rail vehicle by arithmetic measures. A time of closure is specified for triggering a closure of the railroad crossing as a function of the calculated properties of the rail vehicle. The velocity and the acceleration are calculated from the measurement data of the axle counter. The time of closure of the railroad crossing is specified with reference to the calculated velocity and the calculated acceleration as the rail vehicle is leaving the axle counter. An apparatus for operating a railroad crossing, a computer program product and a delivery apparatus for the computer program product are also provided.

A method for monitoring a railway track (11) is provided, the method comprising detecting monitoring signals (MS) by a distributed acoustic sensor (10) being arranged along the track (11), where each monitoring signal (MS) comprises a monitoring signal value (MSV) for a first measurement segment (12) of the distributed acoustic sensor (10) and a monitoring signal value (MSV) for a second measurement segment (22) of the distributed acoustic sensor (10), determining a first event monitoring signal value (EV1) for the first measurement segment (12) from the monitoring signal values (MSV) that are detected during the passage of a rail vehicle over the position of the first measurement segment (12), determining a second event monitoring signal value (EV2) for the second measurement segment (22) from the monitoring signal values (MSV) that are detected during the passage of a rail vehicle over the position of the second measurement segment (22), and determining a difference value (DV) where the difference value (DV) relates to the difference between an average relative value (ARV) and a relative value (RV), where the relative value (RV) is given by the relative difference between the first event monitoring signal value (EV1) and the second event monitoring signal value (EV2), wherein the average relative value (ARV) relates to an average value of relative values (RV) determined from previous passages of rail vehicles. Furthermore, a monitoring system (15) for monitoring a railway track (11) is provided.

A sensor device for placement on a rail track and a method for placing the sensor device. The sensor device includes one or more permanent magnets positioned such that the sensor device is mountable on the lateral side of the rail track by magnetic attraction. A housing includes a base side, a mounting side, and a top side opposite the base side, where the mounting side includes first, second and third contact edge regions configured to be in contact with the rail track. The second contact edge region is positioned outwardly from a first plane through both the first contact edge region and the third contact edge region, and the second contact edge region is positioned between a second plane parallel to the top side and through the first contact edge region and a third plane parallel to the second plane and through the third contact edge region.
