This part of prEN 16432 covers system and subsystem design and component configuration for ballastless track system.
The system and subsystem design requirements are assigned from the general requirements of prEN 16432 1:2014. Where applicable existing subsystem or component requirements from other standards are to be referenced.

Bahnanwendungen - Feste Fahrbahn-Systeme - Teil 2: Teilsysteme und Komponenten

Dieser Teil der prEN 16432 behandelt die Bemessung von System und Teilsystem und die Anordnung der Komponenten für Feste Fahrbahn-Systeme (FF-Systeme).
Die Entwurfsanforderungen an das System und das Teilsystem sind prEN 16432 1:2015 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 : Sous-systèmes et composants

La présente partie de l’EN 16432 traite de 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 du prEN 16432 1:2014. Le cas échéant, les exigences existantes relatives aux sous systèmes ou aux composants figurant dans d’autres normes doivent être appliquées.

Introduction
This part of the series EN 16432 covers the design of the ballastless track system, subsystems and
components and is used in conjunction with the following parts:
— Part 1: General requirements;
— Part 3: Acceptance.
A ballastless track system may consist of, but is not limited to, subsystems and components shown in
5.1, Figure 1. Those items are designed in accordance with the requirements defined in this standard, or
if applicable, other existing European standards.
NOTE Typical examples are rails defined in EN 13674–1, EN 13674–2 and EN 13674–3 or rail fastenings for
ballastless track system defined in EN 13481–5.
