FIELD: railway transport; signaling and communication.
SUBSTANCE: invention is designed for interval control of traffic. According to proposed method, ac signal is applied to rail line at one end, and at other end running value of signal is compared with track clear voltage threshold value. Track is considered clear when running value of signal exceeds clear voltage threshold value. Line generator and receiver are connected in turn to each rail line of section between stations and voltage of beginning and end of rail line and current of supply source are recorded. Summary input resistance of two adjacent rail lines is determined and averaged value of input resistance of rail line is found. Track clear voltage threshold value corresponds to each averaged resistance value.
EFFECT: improved safety owing to increased reliability of checking of rail lines.
