Railway applications - Track - Switches and crossings for Vignole rails - Part 3: Requirements for wheel/rail interaction

This part of this European Standard defines the main wheel/track interaction criteria to be taken into account during the geometrical design of switches and crossings (S&C) layouts.
It specifies:
-   characterisation of wheel and track dimensions;
-   geometric design principles for wheel guidance;
-   design principles for wheel load transfer;
-   deciding whether movable crossings are needed.
These are illustrated by their application to turnout components:
-   switches;
-   crossings;
-   check rails,
but the principles apply equally to more complex layouts. There are also simplified definitions of the safety and functional dimensions, which can be used in conjunction with the general principles as the basis for more in-depth assessment.

Bahnanwendungen - Oberbau - Weichen und Kreizungen für Vignolschienen - Teil 3: Anforderungen an das Zusammenspiel Rad/Schiene

Der vorliegende Teil dieser Europäischen Norm legt die Hauptkriterien des Zusammenspiels Rad/Schiene fest, die während der Phase des geometrischen Entwurfs von Gleisanlagen mit Weichen und Kreuzungen zu berücksichtigen sind.
Er legt Folgendes fest:
-   die Beschreibung der Rad- und Gleisabmessungen;
-   die geometrischen Entwurfsgrundsätze für die Radführung;
-   Entwurfsgrundsätze für die Radlastübertragung;
-   die Entscheidung darüber, ob Herzstücke mit beweglichen Bauteilen erforderlich sind.
Diese werden entsprechend ihrer Anwendung auf die Weichenbauteile
-   Zungenvorrichtungen;
-   Herzstücke;
-   Radlenker;
dargestellt, jedoch sind die Grundsätze gleichermaßen auch auf umfangreichere Gleisanlagen anwendbar. Es gibt auch vereinfachte Definitionen der Sicherheits- und Funktionsmaße, die in Verbindung mit den allgemeinen Grundsätzen als Grundlage für eine tiefergehende Bewertung angewendet werden können.

Applications ferroviaires - Voie - Appareils de voie - Partie 3: Exigences pour l'interaction Roue/Rail

La présente partie de la Norme Européenne définit les principaux critères d'interaction entre les roues et la voie à prendre en compte pendant la conception géométriques des types d'appareils de voie.
Elle spécifie :
-   la caractérisation des dimensions des roues et des voies ;
-   le principe de conception géométrique pour le guidage des roues ;
-   les principes de conception pour le transfert de charge des roues ;
-   la décision sur la nécessité d’utiliser des cœurs à parties mobiles.
Les sujets sont illustrés par l'application aux composants du branchement :
-   aiguillages ;
-   cœurs ;
-   contre-rails,
mais les principes s'appliquent également aux appareils de voie plus complexes. Il existe également des définitions simplifiées des dimensions sécuritaires et fonctionnelles, qui peuvent être utilisées conjointement avec les principes généraux comme base d'une évaluation plus approfondie.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 256.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United
Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are aware and to
provide supporting documentation.
