Railway applications - Ballastless track systems - Part 2: System design, subsystems and components

This part of FprEN 16432 specifies system and subsystem design and component configuration for ballastless track system.
The system and subsystem design requirements are assigned from the general requirements of FprEN 16432-1:2016. Where applicable, existing subsystem or component requirements from other standards are to be referenced.

Bahnanwendungen — Feste Fahrbahn-Systeme — Teil 2: Systementwurf, Teilsysteme und Komponenten

Dieser Teil von EN 16432 behandelt die Bemessung von System und Teilsystem und die Anordnung der Komponenten für Feste Fahrbahn-Systeme (FF-Systeme).
Die Konstruktionsanforderungen an das System und das Teilsystem sind den allgemeinen Anforderungen von EN 16432 1:2016 entnommen. Auf Anforderungen an bestehende Teilsysteme oder Komponenten aus anderen Normen ist zu verweisen, sofern zutreffend.

Applications ferroviaires - Systèmes de voies sans ballast - Partie 2 : Conception du système, sous-systèmes et composants

La présente partie de l’EN 16432 spécifie la conception du système et des sous-systèmes et de la configuration des composants destinés au système de voie sans ballast.
Les exigences relatives à la conception du système et des sous-systèmes sont dérivées des prescriptions générales de l’EN 16432-1. Le cas échéant, les exigences existantes relatives aux sous systèmes ou aux composants figurant dans d’autres normes doivent être appliquées.

Železniške naprave - Progovni sistemi z utrjenimi tirnicami - 2. del: Projektiranje sistema, podsistemi in sestavni deli

Ta del standarda prEN 16432 zajema projektiranje sistemov in podsistemov ter konfiguracijo sestavnih delov za progovni sistem z utrjenimi tirnicami.
Zahteve glede projektiranja sistemov in podsistemov so navedene v skladu s splošnimi zahtevami standarda prEN 16432 1: 2014. Po potrebi se je treba sklicevati na obstoječe zahteve za podsisteme ali sestavne dele iz drugih standardov.
