SummaryProblems with overhead equipmentOverviewConstructionTypes of wiresTensioningBreaksOverhead conductor rails

Overhead lines may be damaged by strong winds. Lightning can hit overhead wires or supporting systems, stopping trains with a power surge. During cold or frosty weather, ice may coat overhead lines. This can result in poor electrical contact between the collector and the overhead line, resulting in electrical arcing and power surges. Ice coatings also add extra weight, as well as increase their surface area exposed to wind, consequently increasin
