Abstract: A sensor arrangement for a railway system may include a rail claw that is connectable to a rail of the railway system, and a sensor that is configured to measure a spatial position of at least a segment of a movable railway element of the railway system by a contactless measurement and to differentiate between at least two different spatial positions of the segment of the movable railway element. The sensor may be mechanically connected with the rail claw. Furthermore, a method for monitoring a railway system is provided.

Abstract: A sensor arrangement for a railway system is provided. The sensor arrangement may include a plurality of sensors, each sensor having a coil. The sensors may be arranged in a two-dimensional arrangement, each sensor may have a sensing range within which the respective sensor is configured to detect movement of electrically conductive material, and for each position along a sensing distance within the two-dimensional arrangement, the sensor arrangement may include at least two sensors of the plurality of sensors whose sensing range extends over the respective position.

Abstract: A monitoring unit for monitoring a railway track is provided. The monitoring unit may include a processing unit, at least one wheel sensor connectable to a rail of the railway track, and a sensor arrangement connectable to a railway switch of the railway track. The wheel sensor and the sensor arrangement may be connected with the processing unit, and the processing unit may include an output that is connectable to a signaling system. Furthermore, a method for monitoring a railway track is provided.

Abstract: A method for monitoring a railway system is provided. The method may include arranging a sensor below a movable railway element of the railway system, and measuring a spatial position of at least a segment of the movable railway element by a contactless measurement by the sensor. The sensor may be configured to differentiate between at least two different spatial positions of the segment of the movable railway element, and the respective spatial position may relate to the distance between the segment of the movable railway element and a rail of the railway system. Furthermore, a sensor arrangement for a railway system is provided.
