This document was prepared in the UIC Infrastructure Forum by the Traction and Energy Experts Group to provide Infrastructure Managers (IM) with guidelines for maintenance of overhead contact lines (OCL) based on uniform criteria and common objectives.
OCL have been divided into their main components or parts to be taken into account for planning and performing maintenance operations.
At the same time the main parameters to be checked, measured or observed and the operations/interventions to be carried out have been identified, as well as the data that should be examined to evaluate the condition of the OCL and to ensure expected performance.
