摘要： A grade crossing control system includes a controller that receives start and end inputs corresponding to a train traversing an outer approach, determines the difference in time between the start and end inputs, and uses the difference in time to determine a delay period by which activation of a grade crossing warning system will be delayed following detection of the train by a track occupancy circuit in an inner approach in order to compensate for slow moving trains. The start and end inputs for the outer approach may be supplied in different ways including a separate track occupancy circuit for the outer approach, by train detection devices unconnected to the track at the start and end of the outer approach, or by overlapping track occupancy circuits positioned at the start of the outer and inner approaches.

The cable is buried under the track bed.

摘要： A device for detecting an occupied or available status of a track segment has a transmitter for feeding in a transmitted signal into the travel rails of the track segment and at least one receiver for receiving a received signal generated by transmitting the transmitted signal via the travel rails of the track segment. In order to simplify commissioning, the device is implemented for varying the frequency of the transmitted signal, for determining a resonant frequency of the transmitted signal, and for adjusting the frequency of the transmitted signal to the determined resonant frequency. A method for operating the device for detecting the occupied or available status of a rail segment is further discussed.

摘要： A railway circuit for detecting the free or occupied state of the same and for sending signalling information along a railway line to a vehicle travelling along said railway line. A signal generator generates a signal with varying current modulated with FSK technique on a basis of a modulation code. The signal is supplied to a coil magnetically coupled with first and second rails that constitute the single railway circuit to induce a variable current modulated by the code on the electric circuit formed by the portions of the first and second rail short-circuited alternatively by the electric joint. The vehicle is provided with a current sensor suitable for detecting the variable current for extraction of the code and sending the signal to the driver. A signal generator generates a signal in compliance with new safety requirements to determine, with the receiver, the free/occupied state of the railway circuit.

摘要： An overlay track circuit is used to transmit information through a block of railroad tracks. In one embodiment, one of a plurality of codes assigned to a receiver/transmitter pair are used to represent each information segment (which may be one or more bits) of an information signal. In another embodiment, bits of the information signal are transmitted between periodic repetitions of a code associated with the transmitter/receiver pair. The modulation may be performed using a frequency shift key technique. Track circuits may be connected to relay information between adjacent blocks of track.
