Anotation

IEC 61375-1:2026 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 IEC 61375-1 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. IEC 61375-1 might be additionally applicable to closed trains and multiple unit trains when so agreed between purchaser and supplier. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Extension of train backbone topologies: aggregated and segregated topology; b) Added independent consist orientation check with segregated train backbone topology; c) Introduction of wireless technologies: wireless train backbone and wireless consist network; d) Possibility of virtual networks; e) Definition of data classes and protocol requirements suitable for the OMTS domain; f) New clause about cybersecurity in train communication networks. LIEC 61375-1:2026 s’applique a l’architecture des systemes de communication de donnees dans les trains a composition variable, c’est-a-dire qu’elle couvre l’architecture d’un systeme de communication de donnees entre les vehicules des trains consideres, les communications de donnees dans les vehicules et les communications de donnees train-sol. Lapplication de IEC 61375-1 aux technologies de reseau de train permet linteroperabilite de vehicules individuels dans des trains a composition variable en trafic international. Les systemes de communication de donnees dans les vehicules sont donnes comme solutions recommandees pour fonctionner avec ledit TCN. Dans tous les cas, le fournisseur devra apporter la preuve de la compatibilite entre un reseau central de train propose et un reseau de rame propose. Par ailleurs, IEC 61375-1 pourrait sappliquer aux rames non modifiables et aux trains a unites multiples apres accord entre acheteur et fournisseur. Cette quatrieme edition annule et remplace la troisieme edition publiee en 2012. Cette edition constitue une revision technique. Cette edition inclut egalement les modifications techniques majeures suivantes par rapport a ledition precedente: a) Extension des topologies de reseau central de train: topologie agregee et separee b) Ajout dune verification independante de lorientation de la rame avec une topologie separee de reseau central de train c) Introduction des technologies sans fil: reseau central de train sans fil et reseau de rame sans fil d) Possibilite de reseaux virtuels e) Definition des classes de donnees et des exigences de protocole adaptees au domaine OMTS f) Nouvel article sur la cybersecurite dans les reseaux embarques de train
