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.
