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.

Abstract: The railroad track wire connection is configured for electrically connecting a first element of a railroad installation to a second element of the railroad installation, the first element and the second element being electrically conductive, at least one of the first element and the second element being a rail of a line of rails of a railroad track of the railroad installation. The railroad track wire connection comprises at least one first element wire having a proximal end for connection to the first element and a distal end, a first element connector provided at the distal end of each first element wire, the first element connector being configured for electrical connection with the second element directly or via a mating second element connector, wherein the first element connector comprises a magnetic element for generating a magnetic force with the second element for fixing the first element connector to the second element in a removable manner or with a magnetic element of the second element connector for fixing the first element connector to the second element connector in a removable manner.
