This document applies to overhead contact line systems in heavy railways, light railways, trolley buses and industrial railways of public and private operators. This document applies to new installations of overhead contact line systems and for the complete renewal of existing overhead contact line systems. This document contains the requirements and tests for the design of overhead contact lines, requirements for structures and their structural calculations and verifications as well as the requirements and tests for the design of assemblies and individual parts. This document does not provide requirements for ground level conductor rail systems (see Figure 1).
