A grade crossing control system includes a track circuit with a grade crossing predictor (GCP) system coupled to rails of a railroad track at a grade crossing, wherein a railroad vehicle travelling on the railroad track causes a change of impedance when entering the track circuit, and wherein the GCP system generates grade crossing activation signals in response to the change of the impedance of the track circuit, wherein, for detecting the change of impedance, the GCP system includes a first transmitter transmitting a first signal over the track circuit and a first receiver detecting a first response signal, a second transmitter transmitting a second signal over the track circuit and a second receiver detecting a second response signal, wherein the first transmitter and the first receiver are preprogrammed to a first frequency, and wherein the second transmitter and the second receiver are preprogrammed to a second frequency.

The present invention relates to methods of improving the reliability and accuracy of level crossing warning systems. The invention is comprised of an axle counter based system that detects the presence and calculates the speed of a train approaching a level crossing and adjusts the activation time for any warning system using a pre-defined period.

A method for warning a motor vehicle of a collision with a rail vehicle, in which, using an electronic computing device arranged externally of the vehicle, first movement data of the rail vehicle, which characterize a position and/or a speed of the rail vehicle, are received from a sensor device permanently installed in a rail network and/or are determined as a function of an electronic timetable. A hazardous situation is determined as a function of the first movement data and position data of at least one level crossing, which position data characterize a position of the level crossing. A hazard information signal, which can be called up by the motor vehicle and characterizes the hazardous situation, is provided for the motor vehicle as a function of the hazardous situation.

A method for securing a level crossing permits timely securing of the level crossing and is particularly effective and reliable. The method proceeds in such a way that vehicle data are received from a track-bound vehicle approaching the level crossing by a stationary control device of a train control system. The vehicle data include at least the current position and the current speed of the track-bound vehicle. A strike-in point is determined on the basis of the received vehicle data and route data including at least the location of the level crossing. Securing of the level crossing is triggered when the strike-in point is reached. A stationary control device for a train control system and an arrangement having such a stationary control device are also provided.
