Abstract
Disclosed is a method of checking for track vacancy of a non-branching section by an audio frequency track circuit, at which from a supply end of the track circuit the voltage is applied to the rail line (section) and the amplitude of obtained voltages is controlled at relay ends. Power from a generator is fed to a point of switching the relay ends and only then to a rail line, then at the relay end the total voltage is received followed by determination of the vacancy of the rail line.
