This European Standard was approved by CENELEC on 2000-11-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any
other language made by translation under the responsibility of a CENELEC member into its own
language and notified to the Central Secretariat has the same status as the official versions.

Foreword
This European Standard was prepared by SC 9XC, Electric supply and earthing systems for public
transport equipment and ancillary apparatus (fixed installations), of the Technical Committee CENELEC
TC 9X, Electrical and electronic applications for railways.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50119
on 2000-11-01.
The following dates were fixed:
- latest date by which the EN has to be implemented at national (dop) 2002-01-01
level by publication of an identical national standard or by
endorsement
- latest date by which the national standards conflicting with the (dow) 2003-11-01
EN have to be withdrawn
Annexes designated “normative” are part of the body of the standard. Annexes designated
“informative” are given for information only. In this standard, annexes A and B are normative.
This European Standard has been prepared under a mandate (M024) given to CENELEC by the
European Commission and supports the Public Procurement Directive, 93/38/EEC.
References to definitions in IEC 60050-811 in clause 3 are included for user reference and in some
cases may update or modify the current definition.

1 Scope
This European Standard applies for the design and construction of electric traction overhead contact
lines in railway and tramway applications (see clause 4).
The standard is intended to be used by the system designer for the new construction of electric
traction overhead contact lines or for the complete transformation of existing lines according to the
client performance objectives. This document does not deal in detail with railway traction electrical
supply systems or EMC requirements and is not applicable to feeders which are remote from the
track.
2 Normative references
