AUDIO-FREQUENCY TRACK CIRCUITS FOR CHECKING OF TRACK SECTIONS

TONFREQUENZ-GLEISSTROMKREISE ZUM UEBERWACHEIV VON GLEISABSCHNITTEN

Track circuits provide the information about the vacancy and occupancy state of line tracks, station tracks and points. Track circuits up to now were operated by direct or alternate voltage and required the division of the track into sections insultated from each other. By application of audiofrequencies, such a separation is unnecessary; the section ends form electrical separating bonds deriving from electrical separating bonds deriving from a connection of rail joints and condensers under utilization of the inductive resistance of the rails. The shorter length of the audiofrequency track circuits compared with the conventional ones permits their use on outer suburban railways or for special tasks on long distance railways.
