PRECIS DE LA DIVULGATION: Dispositif de transmission d'informations dont les zones de propagation des signaux d'information sont indépen- dantes des sections du système de cantonnement. Un générateur de signaux alternatifs modulés par des signaux à transmettre est couplé à des files de rails par induction, au moyen d'une spire en aval de la zone. Chaque zone de transmission d'informations est délimitée en amont et en aval par des circuits résonnants accordés sur la fréquence porteuse des signaux émis. Cette fréquence est choisie de manière à éviter toute interaction entre les circuits de voie et le dispositif de transmission d'informations. Application à la circulation ferroviaire.
