Abstract: An onboard system transmits a train occupancy range based on a measured train position to a ground system. The ground system provisionally detects the occupancy state of each block section based on the train occupancy range acquired from the onboard system. Exit detection points (Qh, Qr) are set at a position outside each block section. It is determined that the train has left the block section when the entirety of the train occupancy range has passed the exit detection point (Qh, Qr). When the provisional detection result indicates that the detection target block section is not occupied, and it has been determined that the train has left the detection target block section, it is determined that the detection target block section is not occupied.

Abstract: A method and an apparatus control railway safety systems, in particular train routing systems and railway crossing systems. In order to simplify the railway line infrastructure while increasing the safety level at the same time, it is provided that the vehicle emits an RFID—radio frequency identification—signal which contains vehicle data and is read and evaluated by a device on the railway line in order to generate control input variables.

Abstract: The invention concerns a system for sensing train wheels which employs a slotted detector bar. Optical resistive and piezoresistive strain gauges may be coupled to the detector bar as well as enhanced mechanical and electrical components. Optional equipment including an optical sensor, and pulse and frequency modulators improve noise immunity and reduce power consumption.

Abstract: A railroad car hot box detector system is provided which includes a variable circuit means for processing the heat signal generated by an infra-red detector viewing a sensing zone along a section of track. The system includes a conditioning circuit which determines one or more conditions of the train (such as the wheel speed or temperature of the car bottom) and uses that information to vary the processing circuit to enable the heat signal to be processed optimally for the detected condition.

Abstract: An improved method and circuit is provided for processing waveforms from a railway car heat signal to eliminate spurious signals and to differentiate between roller bearings and friction bearings in a railroad hot box detector system. The waveforms generated by passing bearings are discretely sampled and spurious signals are eliminated by considering only those signals that fall within the crossing points of a threshold value. Discrimination between roller bearings and friction bearings is obtained by determining the ratio of the sum of the discrete values of the amplitude of the waveform within a first set of samples between the crossing points to the sum of the discrete values of the amplitude of the waveform within a second set of samples between the crossing points.

Abstract: A system for the surveillance of a route along which vehicles are moving, and which operates in real time, comprises radar equipment whose transmitter and receiver are each connected to a leak line acting as an antenna for respectively transmitting outgoing energy from the radar unit and conveying reflected energy back to the radar unit. These lines are mutually decoupled so that only the line connected to the receiver picks up the energy reflected by a moving object or a fixed obstacle situated on the surveyed route.
