To provide a technology of a track circuit device with a principle completely different from those of conventional track circuit devices.SOLUTION: A track circuit device 1 measures a transmission voltage and a transmission current of an alternating signal transmitted to a rail, calculates an impedance equivalent value based on an amplitude and a phase difference of the measured transmission voltage and transmission current, and determines whether a train exists on a rail based on values of a real component and an imaginary component of the calculated impedance equivalent value.SELECTED DRAWING: Figure 1
