New wheel detectors for switching and indication functions
The newly developed Wheel Sensor Relay (WSR) and Wheel Sensor Single (WSS) Wheel Detectors from Siemens are used for the initiation and normalisation (strike-in and strike-out) of level crossings and to perform switching and indication functions in interlockings and hump yards. The WSS Wheel Detector is also used to indicate trailed points. The particular challenges of eddy-current brakes, as they were first used in the ICE 3, are fully overcome by the two wheel detectors. The new WSR and WSS Wheel Detectors replace intermittent track-installed switching devices and earlier types of wheel sensor from Siemens which have been in use for decades. The WSR Wheel Detector replaces the MK Magnetic Wheel Detector, the WSSB-Impulsgeber (pulse generator) and S44 Rail Treadle. The WSS Wheel Detector replaces the RSE Wheel Sensor.
