Railway applications - Track - Switches and crossings - Part 3: Requirements for wheel/rail interaction
This part of this European Standard 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.

Diese Europäische Norm umfasst folgende Bereiche:
3 Beschreibung der Rad- und Gleismaße;
3 geometrische Entwurfsgrundsätze für die Radführung;

3 Entscheidung darüber, ob Herzstücke mit beweglichen Bauteilen erforderlich sind.
Diese werden in ihrer Anwendung auf die Weichenbauteile
3 Zungenvorrichtungen;
3 Herzstücke;
3 Radlenker

Applications ferroviaires - Voie - Appareils de voie - Partie 3: Exigences pour l'interaction Roue/Rail
La présente partie de la Norme européenne traite des sujets suivants :
caractérisation des dimensions des roues et des voies ;
principe de conception géométrique pour le guidage des roues ;
principe de conception pour le transfert de charge des roues ;
décision sur la nécessité d'utiliser des c?urs a parties mobiles.
Les sujets sont illustrés par l'application aux composants du branchement :
aiguillages ;
c?urs ;
contre-rails.
mais les principes s'appliquent également aux appareils de voie plus complexes.

EN 13232-3:2003 (E)3ForewordThis document (EN 13232-3:2003) has been prepared by Technical Committee CEN/TC 256 "Railwayapplications", the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by February 2004, and conflicting national standards shall be withdrawn at the latestby February 2004.This series of European Standards “Railway Applications – Track – Switches and Crossings” covers the design andquality of switches and crossings in flat bottomed rail. The list of parts is as follows:¾ Part 1 : Definitions¾ Part 2 : Requirements for geometric design¾ Part 3 : Requirements for wheel/rail interaction¾ Part 4 : Actuation, locking and detection¾ Part 5 : Switches¾ Part 6 : Fixed common and obtuse crossings¾ Part 7 : Crossings with movable parts¾ Part 8 : Expansion devices¾ Part 9 : LayoutsPart 1 contains terminology used throughout all parts of this series. Parts 2 to 4 contain basic design guides andare applicable to all switch and crossing assemblies. Parts 5 to 8 deal with particular types of equipment, includingtheir tolerances. Part 9 defines the functional and geometric dimensions and tolerances for layout assemblies.These use Parts 1 to 4 as a basis.The following terms are used within to define the parties involved in using the European Standard as the technicalbasis for a transaction:¾ Customerthe Operator or User of the equipment, or the Purchaser of the equipment on the User's behalf;¾ Supplierthe body responsible for the use of the European Standard in response to the Customer'srequirements.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 13232-3:2004

Some of these rules assume a 2-axle bogie or vehicle. The need for other specialrequirements such as those posed by 3-axle or other vehicles must be stated by the Customer.3.2 Wheel and track dimensionsThis clause deals with the key dimensions needed for the analysis of the interaction between wheels and the track,either for guidance calculations or load transfer calculations.Wheel and track dimensions are defined below.3.3 Wheel profilesSufficient dimensions of the cross-section or profile of a wheel are required for switch and crossing design. As aminimum, a dimensioned profile drawing shall be provided by the customer, with the following key dimensions asdefined in Figure 1:¾ flange width, height and flange angle;¾ tyre width and tread angle;¾ wheel diameter or radius.SIST EN 13232-3:2004
