Overhead contact line inspection system, which can be installed on a rail and road car, has been developed. It consists of a small-size contact wire wear measuring instrument and a small-size pantograph with various sensors. It can be used in daytime at the maximum inspection speed of 30km/h, which is limited by the car running stability. From the results of laboratory and field test, it has been proved that the wear measurement is accurate enough for practical use.
