The method comprises steps of: receiving a static test request transmitted by a train in four carriages coupling mode on the track B1 or the track B2, determining whether a test environment of the train satisfies a static test condition, and transmitting a static test permission instruction to the train; receiving a dynamic test request transmitted by the train, determining whether a test environment of the train satisfies a dynamic test condition, and transmitting a dynamic test permission instruction to the train; and receiving information, indicating that the train can be woken up, transmitted by the train, and controlling the train to wake up from sleep state.

A method for operating a railroad crossing includes using an axle counter to capture measurement data for rail vehicles approaching the railroad crossing during passage of the rail vehicle. The velocity and the acceleration of the rail vehicle are calculated from the measurement data as properties of the rail vehicle by arithmetic measures. A time of closure is specified for triggering a closure of the railroad crossing as a function of the calculated properties of the rail vehicle. The velocity and the acceleration are calculated from the measurement data of the axle counter. The time of closure of the railroad crossing is specified with reference to the calculated velocity and the calculated acceleration as the rail vehicle is leaving the axle counter. An apparatus for operating a railroad crossing, a computer program product and a delivery apparatus for the computer program product are also provided.

A system and a method automatically detect whether a vehicle entering a track section of a railway network is shorter than a predefined length. The method includes detecting at a time T0 an entry of the vehicle on a first track subsection. From the time T0, the occupancy states of at least a first subsection and a third subsection are determined in dependence on the time. The occupancy state is either “occupied” or “free”. The occupancy states for at least first and third subsections is reported to an evaluation unit at least until the occupancy state of the first subsection is “free”. The reported occupancy states determined for the at least first and third subsections are processed by the evaluation unit, and from a temporal evolution of the occupancy states of the first and third subsections, it is determined whether the entering vehicle is shorter than the predefined length.

A method operates a track-bound traffic system which in a particularly efficient manner and at the same time with a comparably low degree of complexity allows the position of at least one vehicle end of a track-bound vehicle to be ascertained. For this purpose, the method is carried out such that a track-side device transmits first information which directly or indirectly characterizes the location of the track-side device and second information which directly or indirectly characterizes the travel direction of a track-bound vehicle. The first and second information is received by the track-bound vehicle at the location of the track-side device; and a position of at least one vehicle end of the track-bound vehicle is ascertained by the track-bound vehicle on the basis of the received first and second information.

A frequency generator for generating a working frequency for a transmission signal of a rail contact of an axle counter includes a series resonant circuit having a transmitter coil unit of the rail contact and a capacitor. The frequency generator has an inverter, the output of which is connected to the capacitor. The inverter is configured to generate an oscillating voltage and to feed the generated oscillating voltage to the transmitter coil unit of the rail contact via the capacitor. A current transformer synchronizes the output voltage of the inverter to the current in the series resonant circuit. A start-up circuit electrically connected to the inverter is configured to trigger the inverter and to be electrically connected to an input power supply. The frequency generator is a robust and effective circuit for generation of magnetic fields where manufacturing effort and expensive components can be reduced.

A train wireless system includes a train detecting apparatus on the ground and a controller on a train. The detecting apparatus includes a detector and a calculator. The detector detects that the train is on rails in a block. The calculator measures an on-rail time during which the detector detects the train in the block, and calculates an on-rail detecting time during which the train has been on the rails in the block. The controller includes a distance measurer, a time measurer, a recorder, and a train-length calculator. The distance measurer measures a travelling distance of the train from a beginning of the block, the time measurer measures an elapsed time since the distance measurer starts the measurement, the recorder records the elapsed time and the travelling distance, and the train-length calculator searches the recorder based on the detecting time, and calculates the train length using a selected travelling distance.

A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held ‘TRUE’ if they are already ‘TRUE’ when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.

This method is for managing a railway electrical circuit (3A, 3B) adapted to detect presence of a rolling stock (T) on a railway track (1), the railway track (1) being subdivided in successive track sections (1A, 1B) forming successive electrical circuits (3A, 3B) independently fed with electrical current for monitoring the presence of a rolling stock (T) on one of the track sections (1A, 1B), each electrical circuit (3A, 3B) comprising a transmission device (9A, 9B) for feeding the electrical circuit (3A, 3B) with electrical current, located at one end of the track section, and a reception device (11A, 11B) for detecting the electrical current circulating in the electrical circuit (3A, 3B), located at an opposed end of the track section. This method comprises steps consisting in a) continuously feeding the electrical circuit (3A, 3B) with electrical current with the transmission device (9A, 9B) and monitoring the presence of a rolling stock (T) on the corresponding track section (1A, 1B) by measuring, using the reception device (11A, 11B), the current circulating in the electrical circuit (3A, 3B); b) if the reception device (11A, 11B) detects that a rolling stock (T) is present on the track section (1A, 1B), applying to the electrical circuit (3A, 3B) a nominal electrical power (PN) at least until the rolling stock (T) exits the section (1A, 1B); c) if the reception device (11A, 11B) detects that no rolling stock (T) is present on the track section (1A, 1B), applying to the electrical circuit (3A, 3B) a power-saving power value (P0) which is inferior to the nominal power (PN). At step b), the electrical power (P.sub.OT) consumed by the electrical circuit (3A, 3B) is kept under a limited value (P2). A system for detecting presence of a rolling stock (T) on a railway track (1) is also provided.
