This document (EN 50119:2020) has been prepared by CLC/SC 9XC, "Electric supply and earthing systems for
public transport equipment and ancillary apparatus (Fixed installations)" of CLC/TC 9X “Electrical and electronic
applications for railways”.
The following dates are fixed:
• latest date by which this document has to be (dop) 2021-01-13
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards (dow) 2023-01-13
conflicting with this document have to be
withdrawn
This document supersedes EN 50119:2009, as impacted by EN 50119:2009/A1:2013.
impacted by EN 50119:2009/A1:2013:
— requirements for urban mass transportation system are included;
— requirement for rigid overhead contact line (ROCL) are included;
— additional definitions for new terms are included (Clause 3);
— clearances and geometry of overhead contact line are improved (Clause 5);
— urban aspects are added, e.g. wall anchors (Clause 6);
— monitoring devices and automatic earthing and short-circuiting equipment are included (Clause 7);
— overhead contact line for electric trucks is added (Annex C).
Other improvements of this document came from the publication of IEC 60913.
In relation to Subclause 5.1.3, electrical coordination activities are on-going in CLC/SC 9XC (FprEN 50119, the
EN 50124 series, prEN 50488 and the EN 50122 series). A Technical Report will be proposed.
This document has been prepared under a mandate given to CENELEC by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For the relationship with EU Directive 2016/797/EU, see informative Annex ZZ, which is an integral part of this
document.
1 Scope
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).
