In this paper, experimental results both of wind tunnel test and running test for HEMU-400X pantograph were compared and were analyzed. In wind tunnel test, 1/4scale pantograph for HEMU-400X which is being developed for the maximum speed of 400km/h in Korea were tested to investigate the vertical lift force of pantograph at the operational speed of 250, 270, 300, 330, 360 and 400km/h using lift estimation from 1/4 scaled model results. In the running test of train, the contacting force of pantograph was measured to current operational speed of 300km/h. Finally, the results of vertical lift force of pantograph in wind tunnel test and contacting force for the running test were compared to analyze the aerodynamic characteristics of the pantograph for HEMU-400X.
