Abstract: A system controls a level crossing of a railway track installation. The railway track installation includes at least one track. The system includes at least two magnetometers associated with the at least one track and placed at corners of a crossing area between the at least one track and a road. The system also includes a level crossing control unit configured for receiving data from the magnetometers. Each magnetometer is arranged to detect a respective magnetic field vector of the earth's magnetic field and to send data representative of the magnetic field vector to the control unit. The control unit is configured to elaborate the data to detect changes in the magnetic field vectors due to the presence of a train in the crossing area and to control the level crossing as a function of the detected changes.
