Electronic railway equipment - Train communication network (TCN) - Part 3-4: Ethernet Consist Network (ECN)
IEC 61375-3-4:2014 specifies the data communication network inside a Consist based on Ethernet technology, the Ethernet Consist Network (ECN). The applicability of this part of IEC 61375 to the Consist Network allows for interoperability of individual vehicles within Open Trains in international traffic. This part of IEC 61375 may be additionally applicable to closed trains and Multiple Unit Trains when so agreed between purchaser and supplier.

L'IEC 61375-3-4:2014 spécifie le réseau de communication de données au sein d'une Rame fondée sur la technologie Ethernet, le Réseau Ethernet de Rame (ECN). L'applicabilité de la présente partie de l'IEC 61375 au Réseau Ethernet de Rame permet l'interopérabilité de chaque rame des Trains à rames multiples dans le trafic international. Après accord entre acheteur et fournisseur, la présente partie de l'IEC 61375 peut s'appliquer en outre aux Rames et aux Trains à rames multiples.
Železniške elektronske naprave - Komunikacijsko omrežje vlaka - 3-4. del: Sestava omrežja Ethernet (ECN)
EN IEC 61375-3-4 določa komunikacijska podatkovna omrežja v sestavi omrežja, ki temelji na tehnologiji Ethernet, tj. sestava omrežja Ethernet (ECN). Uporaba tega dela standarda IEC 61375 za sestavo omrežja Ethernet omogoča interoperabilnost posameznih vozil odprtih vlakov v mednarodnem prometu. Ta del standarda IEC 61375 se lahko uporablja tudi za zaprte vlake in vlake z večdelnimi enotami, če se o tem dogovorita kupec in dobavitelj.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61375-3-4 has been prepared by IEC technical committee 9:
Electrical equipment and systems for railways.
