The transfer coefficient of contact wire wave motion at hanger points greatly affects the wave motion propagation characteristics in the overhead contact line and the contact force fluctuation of pantograph. Until now, the coefficient has been estimated only by theoretical values obtained from a string model. ln this study, theoretical results are obtained by using a model that takes into consideration the line flexural rigidity, and the coefficient is measured in a real overhead contact line by the wave separation measuring method and spectrum analysis method. It is confirmed that the measured values are mostly in agreement with theoretical values, and the line flexural rigidity is influential on the transfer coefficient even at low frequencies.
