Electronic railway equipment - Train communication network - Part 1: TCN - Train Communication Network general architecture (IEC 61375-1:2012)

This part of IEC 61375 applies to the architecture of data communication systems in open trains, i.e. it covers the architecture of a communication system for the data communication between vehicles of the said open trains, the data communication within the vehicles and the data communication from train to the ground. The applicability of this part of IEC 61375 to the train network technologies allows for interoperability of individual vehicles within open trains in international traffic. The data communication systems inside vehicles are given as recommended solutions to cope with the said TCN. In any case, proof of compatibility between a proposed train backbone and a proposed consist network will have to be brought by the supplier. This part of IEC 61375 may be additionally applicable to closed trains and multiple unit trains when so agreed between purchaser and supplier.

Matériel électronique ferroviaire - Réseau embarqué de train (TCN) - Partie 1: Architecture générale (CEI 61375-1:2012)

La CEI 61375-1:2012 s'applique à l'architecture des systèmes de communication de données dans les trains à composition variable, c'est-à-dire qu'elle couvre l'architecture d'un système de communication de données entre les véhicules des trains considérés, les communications de données dans les véhicules et les communications de données train-sol. L'application de la présente partie de la CEI 61375 aux technologies de réseau de train permet l'interopérabilité de véhicules individuels dans des trains à composition variable en trafic international. La principale modification technique de cette nouvelle édition par rapport à l'édition précédente consiste en une nouvelle structuration de la série CEI 61375.

Železniške elektronske naprave - Komunikacijsko omrežje vlaka - 1. del: TCN - Splošna arhitektura komunikacijskega omrežja (IEC 61375-1:2012)

Ta del standarda IEC 61375 se uporablja za arhitekturo podatkovnih komunikacijskih sistemov na odprtih vlakih, in sicer zajema arhitekturo komunikacijskega sistema za podatkovno komunikacijo med vozili navedenih odprtih vlakov, podatkovno komunikacijo v vozilih in podatkovno komunikacijo med vlakom in tiri. Uporaba tega dela standarda IEC 61375 za tehnologije omrežja vlaka omogoča interoperabilnost posameznih vozil odprtih vlakov v mednarodnem prometu. Podatkovni komunikacijski sistemi v vozilih so navedeni kot priporočljive rešitve za uporabo navedenega komunikacijskega omrežja vlaka (TCN). V vsakem primeru mora združljivost predlagane hrbtenice vlaka s predlaganim omrežjem kompozicije dokazati dobavitelj. 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 61375-1 has been prepared by IEC technical committee 9:
Electrical equipment and systems for railways.
This third edition cancels the second edition published in 2007 and constitutes a technical
revision.
The main technical changes with regard to the previous edition are as follows:
• new structuring of standard parts. The content of the previous edition has now been moved
to IEC 61375-2-1 and IEC 61375-3-1.
• this part of the standard describes now the general architecture of the onboard train
communication network.

• reconfirmed,
• withdrawn,

INTRODUCTION
IEC 61375-1 defines the general architecture of the Train Communication Network (TCN) so as
to achieve compatibility between consist networks defined by this part of IEC 61375 and train
backbones defined by this part of IEC 61375.
The TCN has a hierarchical structure with two levels of networks, a train backbone and a
consist network:
a) for interconnecting vehicles in close or open trains, this part of IEC 61375 specifies train
backbones with different characteristics;
b) for connecting standard on-board equipment, this part of IEC 61375 specifies consist
networks with different characteristics.
The general architecture of the TCN, which is defined in this part of the standard, shall
c) establish the rules for interconnecting consist networks with train backbones, as
• identifying the interfaces;
• defining the principles of how train topology changes can be discovered;
• defining the basic communication services provided by train backbones to be used by
consist networks;
d) establish basic rules for the train backbone and for the consist network;
e) establish rules for communalities in operation, as:
• patterns for the communication between users;
• addressing principles;
• data classes to be supported.

This part of IEC 61375 may be additionally applicable to closed trains and multiple unit trains
when so agreed between purchaser and supplier.
