An apparatus for supplying a track circuit in a railway line provided with a plurality of track circuits adjacent to one another and electrically insulated from one another. Said circuit comprises a pair of rails (R) formed by parallel metal bars (B) and a transmission block (2), capable of supplying the track circuit via a voltage generator designed to cause a current to flow in the circuit, it being possible for information to be associated to said current signal via a predetermined code. Said current deliv-ered and absorbed by the circuit is detectable by a detection device provided on board a train that is travelling along that track cir-cuit.

L'invention porte sur un appareil d'alimentation d'un circuit de voie dans une ligne de chemin de fer comprenant une pluralité de circuits de voie adjacents les uns aux autres et isolés électriquement les uns des autres. Ledit circuit comprend une paire de rails (R) formée par des barres métalliques parallèles (B) et un bloc de transmission (2), apte à alimenter le circuit de voie par le biais d'un générateur de tension conçu pour amener un courant à circuler dans le circuit, des informations pouvant être associées audit signal de courant par le biais d'un code prédéterminé. Ledit courant délivré et absorbé par le circuit est détectable par un dispositif de détection installé à bord d'un train qui circule le long de ce circuit de voie.
