A simple catenary with copper-steel contact wire is one of overhead contact lines equipped with high-speed lines as Shinkansen. Local wears of the contact wires are visible at the simple catenary with copper-steel contact wire of commercial lines. In addition, as the result of investigations on this line revealed that the wears occurred at overlaps of the overhead contact line and a part of station. We therefore proposed a measure for local wears at the overlaps, and verified the effects on a commercial line. Furthermore, we clarified the cause of wears by monitoring the sliding surfaces of the contact wires at a station.
