Foreword
This European Standard was prepared by SC 9XC, Electric supply and earthing systems for public transport
equipment and ancillary apparatus (Fixed installations), of 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
2009-04-01.
This European Standard supersedes EN 50119:2001.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-04-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) –
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.
National Standards implementing EN 50119:
The National Standards implementing EN 50119 will comprise the full text of the Eurocode (including any
annexes), as published by CENELEC, which may be preceded by a national title page and national foreword,
and may be followed by a National Annex.
A National Annex, if included, may contain information on those parameters or statements in EN 50119 which
are not normative, e.g.
 values where alternative values or informative values only are given in the standard,
 country specific data (e.g. geographical, climatic, etc.), e.g. ice loads or temperature limits,
 the procedure to be used where alternative procedures are given in the standard.
It may also contain
 decisions on the use of informative annexes, and
 references to non-contradictory complementary information to assist the user to apply the standard.
The National Annex shall not alter any provisions of the European Standard.

1 Scope
This European Standard applies to electric traction overhead contact line systems in heavy railways, light
railways, trolley busses and industrial railways of public and private operators.
It applies to new installations of overhead contact line systems and for the complete reconstruction of existing
overhead contact line systems.
This standard 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 standard does not provide requirements for conductor rail systems where the conductor rails are located
adjacent to the running rails.
