Abstract: Trains and points are patrolled by a telegram containing the block occupancy information as a section that only one train is permitted to occupy, the information for giving lock position instructions to a point, and the point position information. This telegram is updated in order to get the right of block occupancy that is not held by other trains, and to give lock position instruction to the point. The train checks the block which this train is allowed to occupy, confirms that the point in this block has been set to the lock position specified by this train. Reading the aforementioned telegram, the point checks the lock position instruction given to itself and controls its lock position. A signaling system characterized by reduced designing and manufacturing costs is provided.

Abstract: A process is disclosed for communication systems used in traffic engineering and having an earthbound transponder for each corresponding track section. The transponders transmit first data through a first path of transmission to polling machines arranged on vehicles. Based on these first data, the concerned polling machine ascertains whether second data transmitted through a second path of transmission to the polling machine are really destined for the vehicles. The signal in the second path of transmission destined for the vehicles of a section of the track is individually modulated or transmitted by a time- or frequency-multiplexing process. Depending on the selected modulation or multiplexing, coefficients are built at the emitter side which are then transmitted through the first path of transmission, extracted at the receiver side and used to demodulate or demultiplex the signal transmitted through the second path of transmission.

Abstract: A wireless train proximity alert system provides a constant warning signal to warn vehicles approaching a train crossing when a train is also approaching the crossing. The system includes a transceiver, positioned on the train itself or at the side of the track, for transmitting a train proximity signal, which preferably includes the train's speed and position. A crossing-based transceiver receives the train's proximity signal and transmits the boundary coordinates of a warning zone when the train's estimated time-to-arrival at the crossing is within a predetermined range. A vehicle-based receiver receives the warning zone signal and the crossing's position, compares them to the vehicle's position and speed, and produces an alarm to the vehicle's operator when a potential accident is indicated.

Abstract: A vehicle guidance system for guiding a vehicle on a virtual track includes a waveguide connected to a member emitting electromagnetic radiation at a frequency between 1 and 100 kHz and disposed on the axis of the track to be followed. At least one set of two magnetic sensors disposed on the vehicle receive the field to determine the lateral offset of the vehicle relative to the axis of the track.

Abstract: Information is transmitted at microwave frequencies, the ground station being connected to a waveguide (25) and the station aboard a railway vehicle being connected to an antenna (26). Each station comprises a microwave generator (19) supplying a carrier, transmitters (3 through 7) supplying subcarriers, receivers (28 through 32) and a pilot generator (1). The carrier and subcarrier frequencies are multiples of the pilot frequency and the frequency difference between adjacent subcarriers equals the pilot frequency. A transmitter mixer (MTX) receives the carrier and the subcarriers and is connected to a circulator (24), itself linked to the waveguide (25) in the ground station and to the vehicle station antenna. A receiver mixer (MRX) is connected via a filter (23) to the circulator (24) and receives the carrier from the microwave generator; the latter mixer is connected to the receivers (28 through 32) to which it sends the subcarriers transmitted by the other station.

Abstract: Disclosed is a waveguide for conducting radio frequency signals along a railroad line comprising the ballast, ties and rails of the railroad line. If the waveguide is utilized for intra-train communication, the wheels, axles and under-vehicle parts of the vehicles of the train comprise the side and upper surfaces of the waveguide. The waveguide may be utilized to: (1) transmit data such as train vehicle journal bearing temperatures, from remote locations to either the caboose or engine of the train; (2) guide radar-type radio frequency pulses ahead of the train; or (3) transmit any other data. In the radar embodiment, reflections received by a receiver on the train represent changes in the characteristic impedance of the waveguide. These reflections may be compared to anticipated reflections in order to detect improper conditions such as broken track or the presence of another train.
