In this paper, we introduce the on-line test of the current collection characteristics for HSR 350x(Korea High Speed Train project) that have been performed in the Kyoung-bu high-speed line since 2002. Through the analysis of measured data during on-line test, the variation trend of contact force between pantograph and contact wire of catenary according to the span type, the track conditions and driving patterns is reviewed. In order to analyze the variation trend of contact force, we have checked the span type of catenary in KP 24 - 125 out of Kyoung-bu high speed line and obtained the statistical processing result per each span type. This study shows that the track conditions do not affect on the dynamic performance between pantograph and contact wire catenary, and the span type and the driving pattern are important factors in determining the good interaction between them.
