IEC 60913:2024 specifies the requirements and tests for the design of overhead contact line systems, 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 is applicable to electric traction overhead contact line systems in heavy railways, light railways, for trolley bus lines, electric road systems (Annex E) and industrial railways of public and private operators. This document is applicable to new installations of overhead contact line systems and for the complete renewal of existing overhead contact line systems.

a) title modified;
b) requirements for urban rail systems are included;
c) requirements for rigid overhead contact line (ROCL) are included;
d) additional definitions for new terms are included (Clause 3);
e) clearances and geometry of overhead contact line are improved (Clause 5);
f) urban aspects are added, for example wall anchors (Clause 6);
g) requirements for monitoring devices, automatic earthing and short-circuiting equipment are included (Clause 7);
h) requirements for overhead contact line for electric vehicles with pantograph on electrified roads are added (Annex E)
i) improvements on the basis of EN 50119:2020 and the questionnaire 9/2619A/Q
