The lift characteristics of two kinds of pantographs were measured with wind tunnel equipment paying attention to the compliance characteristic of a pantograph to improve quality of current collection. We discover the pantograph with metalized carbon sliders (WPS27D) have 25N lift smaller at 130km/h than the one with metal sliders (WPS27C). So, we changed the static upward force of WPS27Ds, performed the quality of current collection examination, and the good result was obtained. This Paper reports the importance of understanding the dynamic characteristic of the pantograph.
