EN 15734-1:2010+A1:2021

Railway applications - Braking systems of high speed trains - Part 1: Requirements and definitions

This European Standard describes the functionality, constraints, performance and operation of a brake system for use in high speed trains as described in the TSI High Speed Rolling Stock, operating on routes of the European railways and their infrastructure systems.
The brake system requirements specified in this European Standard apply to trains that may operate at a maximum speed of up to 350 km/h on lines specifically built for high speed and define graduated values for deceleration related to four speed ranges (see Clause 6).
This European Standard covers:
-   all new vehicle designs of high speed trains;
-   all major overhauls of the above-mentioned vehicles if they involve redesigning or extensive alteration to the brake system of the vehicle concerned.
This European Standard does not cover locomotive hauled trains, which are specified by EN 14198.
NOTE   This document applies the functional subdivision into subsystems as specified in the TSI High speed. The braking system is part of the function: "Accelerate, maintain speed, brake and stop".

Bahnanwendungen - Bremssysteme für Hochgeschwindigkeitszüge - Teil 1: Anforderungen und Definitionen

Diese Europäische Norm beschreibt die Anforderungen an die Funktionalität, die Einschränkungen, die Leistungsfähigkeit und den Betrieb von Bremssystemen für die Anwendung in Hochgeschwindigkeitszügen nach TSI Fahrzeuge HGV, die zum Betrieb auf den Strecken der europäischen Bahnen und deren Infrastruktursystemen bestimmt sind.
Die in der vorliegenden Norm festgelegten Anforderungen für das Bremssystem sind für Züge anzuwenden, die bei einer Höchstgeschwindigkeit von bis zu 350 km/h auf speziell für den Hochgeschwindigkeitsverkehr gebauten Strecken verkehren können und legt für Bremsverzögerungen in vier Geschwindigkeitsbereiche abgestufte Werte fest (siehe Abschnitt 6).
Diese Norm gilt für:
—   alle neuen Fahrzeugbauarten für Hochgeschwindigkeitszüge;
—   alle größeren Grundüberholungen der oben genannten Fahrzeuge, wenn sie Neukonstruktionen oder umfassende Änderungen der Bremsanlage des betreffenden Fahrzeuges mit einschließen.
Diese Norm behandelt nicht lokomotivbespannte Züge, welche in EN 14198 behandelt werden.
ANMERKUNG   Dieses Dokument folgt einer funktionalen Einteilung aus der TSI HGV und behandelt das Bremssystem als Teil der Funktion „Beschleunigen, Geschwindigkeit halten, bremsen und anhalten“.

Applications ferroviaires - Systèmes de freinage pour trains à grande vitesse - Partie 1 : Exigences et définitions

La présente Norme européenne décrit les fonctions, les contraintes, les performances et le fonctionnement
d’un système de freinage destiné à être utilisé sur les trains à grande vitesse décrits dans la STI Grande
vitesse - Matériel roulant, circulant sur des lignes des réseaux ferrés européens et leur infrastructure.
Les exigences du système de freinage spécifiées dans la présente Norme européenne s'appliquent aux trains
pouvant circuler à une vitesse maximale pouvant aller jusqu’à 350 km/h sur des lignes spécialement conçues
pour les trains à grande vitesse et définissent des valeurs de décélération associées à quatre plages de
vitesses (voir Article 6).
La présente Norme européenne couvre :
¾ toutes les nouvelles conceptions de trains à grande vitesse ;
¾ toutes les grandes révisions des véhicules susmentionnés si celles-ci entraînent une reconception ou une
transformation majeure du système de freinage du véhicule concerné.
La présente Norme européenne ne couvre pas les trains remorqués par une locomotive, qui font l’objet de
l’EN 14198.
NOTE Le présent document applique la sous-division fonctionnelle en sous-systèmes comme le spécifie la STI
Grande vitesse - Matériel roulant. Le système de freinage fait partie de la fonction : « Accélérer, maintenir la vitesse,
freiner et s’arrêter ».

Železniške naprave - Zavorni sistemi na vlakih z velikimi hitrostmi - 1. del: Zahteve in definicije

Ta evropski standard opisuje funkcionalnost, omejitve, izvajanje in delovanje zavornega sistema za uporabo pri vlakih z velikimi hitrostmi, kot je opisano v tehničnih specifikacijah za interoperabilnost hitrih vlakov, ki vozijo po evropskih železnicah in njihove infrastrukturne sisteme.
Zahteve za zavorni sistem, določene v tem evropskem standardu, veljajo za vlake, ki lahko vozijo z največjo hitrostjo do 350 km/h po progah, ki so posebej zgrajene za velike hitrosti, in določajo stopnje pojemka pri štirih razponih hitrosti (glej točko 6).
Ta evropski standard zajema:
–   vse nove modele vlakov z velikimi hitrostmi;
–   vse večje obnove zgoraj navedenih vozil, če obnova vključuje preoblikovanje ali obsežno spremembo zavornega sistema zadevnega vozila.
Ta evropski standard se ne uporablja za vlake, ki jih vleče lokomotiva in so navedeni v standardu EN 14198.
OPOMBA:   V tem dokumentu se uporablja funkcionalna razdelitev na podsisteme, kot je določeno v tehničnih specifikacijah za interoperabilnost hitrih vlakov. Zavorni sistem je del funkcije: »pospeševanje, ohranjanje hitrosti, zaviranje in zaustavitev«.
