The unevenness of contact line is one of the factors that considerably affect the dynamic characteristics of contact line and pantograph system. This paper describes the methods to estimate the static installation quality of contact lines by calculating dynamic characteristics and reports some examples of the estimation of real line conditions. The dynamic characteristics, such as contact force fluctuations of pantographs and motion of contact lines, are calculated from the measured unevenness of contact wires, and the calculated results are diagnosed quantitatively. It is confirmed that the calculated values agree well with the measured values. This method is expected to contribute to efficient maintenance of contact lines for high-speed operation.
