Provided by the present disclosure are a track circuit system and an operating method. The track circuit system includes first transmitting equipment, second transmitting equipment, and receiving equipment. The first transmitting equipment and the second transmitting equipment are located on both ends of a track circuit section, respectively. The receiving equipment is located on a track between the first transmitting equipment and the second transmitting equipment. The first transmitting equipment and the second transmitting equipment are configured to respectively transmit a first frequency signal and a second frequency signal to a track in the track circuit section at the same time. The receiving equipment is configured to determine a state of the track circuit section, perform rail breakage detection on the track in the track circuit section, or perform insulation breakage detection on the track in the track circuit section according to the received first frequency signal and second frequency signal. The track circuit system provided by the present disclosure employs a track circuit structure for transmitting at both ends and receiving in the middle, thus achieving double-end code sending of tracks, switchless sections and switch sections of a high-speed railway and an ordinary-speed railway, and the system also has the function of bidirectional return.
