Railway applications - Wheelsets and bogies - Wheels - Tread profile

This European Standard defines the tread profiles of wheels with a diameter greater than or equal to 330 mm used on vehicles running on European standard gauge track to fulfil interoperability requirements.  These profiles apply to new wheels, whether free-standing or assembled as wheelsets, as well as to wheels that require reprofiling during maintenance.

Bahnanwendungen - Radsätze und Drehgestelle - Räder - Radprofile

Die vorliegende Europäische Norm legt die Laufprofile für Räder mit einem Durchmesser größer oder gleich 330 mm fest, die für Ausrüstungen verwendet werden, die auf normalen europäischen Gleisen verkehren, um die Interoperabilität abzusichern. Diese Profile werden sowohl für neue Räder, als Einzelteile geliefert oder zu Radsätzen montiert, als auch für zu reprofilierende Räder im Rahmen der Instandhaltung angewendet.

Applications ferroviaires - Essieux montés et bogies - Roues - Profil de roulement

La présente Norme Européenne définit les profils de roulement des roues de diamètre supérieur ou égal à 330 mm utilisées pour des matériels circulant sur voie normale européenne et qui permettent d’assurer l’interopérabilité. Ces profils s’appliquent aux roues neuves livrées sous forme de roues seules ou calées sur essieux montés, ainsi qu’aux roues devant subir un reprofilage en cours de maintenance.

Foreword
This document (prEN 13715:2015) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This is currently submitted for review.
This document is intended to replace EN 13715:2006+A1:2010

Introduction
This standard states requirements that are in accordance with the principles adopted by the
International Union of Railways.
It describes the rules, parameters and construction methods of the wheel tread profile;
It defines the geometry of the flange and reverse slope. The thicknesses and height of the flange are
determined by the railway undertaking or its representative in compliance with the normative
documents in force;
It defines the co-ordinates and geometry of the following three reference tread profiles of the wheels and their
reverse slope:
th
 1/40 (reverse slope 15 %);
 S1002 (reverse slope 6.7 %, other value used 15 %) in conformity with UIC Leaflet 510-2;
 EPS (reverse slope 10 %) equivalent to profile P8 of the United Kingdom with a flange 30 mm thick.
These three reference profiles are defined in Annexes B, C and D and represent original profiles from the time
of their design, the flanges having been harmonised to a 32.5 mm flange thickness.
It defines the tolerances needed to achieve calibration control.
All the dimensions in this standard are given in millimetres.
1 Scope
This European Standard defines the tread profiles of wheels with a diameter greater than or equal to 330 mm
used on vehicles running on European standard gauge track to fulfil interoperability requirements. These
profiles apply to new wheels, whether free-standing or assembled as wheelsets, as well as to wheels that
require reprofiling during maintenance.
2 Normative references
None apply to this standard.
3 Terms and definitions
For the purposes of this document, the following terms and definitions shall apply.
3.1
Technical specification
Document describing the requirements pertaining to specific parameters in addition to the requirements of this
standard.
4   General
Given that this document describes three reference profiles used in Europe, any other profile that does not conform to this
standard must be defined in a technical specification.
NOTE It is preferred that the profile defined in a technical specification is agreed on between the railway
company and the infrastructure managing organisation.
5  Definition of the tread profile
The tread profile is shown in Figure 1.
