The authors previously reported a remarkable current fluctuation was observed in the axles of the running wheelsets when a track circuit was shunted by the pair of wheelsets. To investigate into the behavior of the fluctuation, they applied a bio-electric amplifier to detect minute voltage potential difference caused by the electric current in the wheelsets. As the results, they found the fluctuation was caused by an electric resonance which was originated in the circuit, composed of the pair of axles and the pair of rails. Analyzing the frequency, they also found the resonance current contained an AF band used for the control device of the grade crossing alarm system.
