In this study, we developed the simulation program of an overhead catenary-pantograph system. The overhead catenary is modeled with point mass and the pantograph is replaced wi th 3 d.o.f model which is composed of mass, spring and damper. Using the developed program, we analyzed the static structure of the overhead catenary and the dynamic characteristics of an overhead catenary-pantograph system such as uplift displacement of contact wire and contact force. we compared the analysis resul ts wi th the results of GASENDO software developed at RTRI in Japan. The behaviors of uplift displacement of contact wire and contact force were similar with the results of GASENDO software.
