The invention discloses a track circuit system and a working method.The track circuit system comprises first sending equipment, second sending equipment and receiving equipment, and the first sending equipment and the second sending equipment are located at the two ends of a track section respectively; the receiving equipment is located on a track between the first sending equipment and the second sending equipment; the first sending device and the second sending device are used for sending a first frequency signal and a second frequency signal to a track in a track section at the same time. And the receiving equipment is used for determining the state of the track section according to the received first frequency signal and the second frequency signal, and carrying out broken track detection on the track in the track section or carrying out insulation damage detection on the track in the track section. According to the track circuit system, a track circuit structure with two-end sending and middle receiving
