A grade crossing control system (400, 600) includes a track circuit with a grade crossing predictor (GCP) system (40), and at least one auxiliary shunting device (420, 430) connected to the rails (20a, 20b) of the railroad track (20), wherein a railroad vehicle travelling on the railroad track (20) causes a change of impedance when entering the track circuit, wherein the at least one auxiliary shunting device (420, 430) detects a presence of the railroad vehicle travelling on the railroad track (20) and generates an auxiliary change of the impedance of the track circuit, and wherein the GCP system (40) generates grade crossing activation signals in response to the change of the impedance or the auxiliary change of the impedance of the track circuit. The auxiliary shunting device is provided to improve reliability in case of poor shunting. In a first implementation the auxiliary shunting device is an additional shunt (428) between rails and within the approaching distance (AL), wherein the shunt is switched on by a separate vehicle detector (422). In a second implementation the termination shunt (SI) is switched off by a vehicle detector (422) before the approaching distance (AL).
