Introduction

This document 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 coordinates and geometry of the following three reference tread profiles of the wheels

and their reverse slope:
— 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 harmonized to a 32,5 mm flange thickness.

It defines the tolerances needed to achieve calibration control.
All the dimensions in this document are given in millimetres.

The profiles comprise:
— two zones H2 – S and S – D1, with fixed geometry;

— a connection zone D1 – C1, unique to each reference profile, to make a tangential connection at

point C1;

— a zone C1 – B1 (either B1a, or B1b) unique to each reference profile. The coordinates are given in

Annexes B, C and D for the three reference profiles including point D0;

— a zone B1 (either B1a or B1b) – A1 – I, comprising the reverse slope and chamfer, unique to each

reference profile. The reverse slope shall be in the range 6,7 % to 15 %.
7 Construction method
7.1 Definition of the axes

The Y-axis is parallel to the axis of rotation of the wheel with the positive values towards the external

face of the wheel. The Z-axis is perpendicular to the latter with the positive values towards the outside

of the wheel. Their origin is at point D0, situated 70 mm from the internal face of the wheel.

7.2 Base profile

The base profile is that obtained with a flange 32,5 mm thick and 28 mm high. All the others are

developed from this fundamental profile.
7.3 Profile construction
7.3.1 Profile zone H2 – D1 (flange)

The reference flange (dimensions, centres and radii) is given in Annex A for a flange thickness of

32,5 mm.

The different flange thicknesses are obtained by translating the zones S – D1, parallel to the Y-axis,

towards the internal face of the wheel. Annex A gives all the coordinates for flange thicknesses between

28,5 mm and 32,5 mm.

After translation, the connection axis (AXB) at the tip of the flange (S) is at a distance, in mm, from the

7.3.3 Profile zone D1 – C1 – D0 for flange thicknesses 28,5 mm ≤ e ≤ 32,5 mm
7.3.3.1 S1002 and 1/40 profiles

For flange thicknesses greater than 28,5 mm, but less than 32,5 mm, the profiles are obtained by

translating the zones D1 – C1 (connection zone) and C1 – T1 along the Y-axis towards the internal face

of the wheel, by an amount equal to the reduction (de) in thickness of the flange.

The position of the point T1 is defined relative to the reference point D0 for all flange thicknesses.

The connection between points D0 and T1 may be smoothed by a straight line.

7.3.3.2 EPS profile

For the flange thickness values greater than 28,5 mm and less than 32,5 mm, the profile shape is

obtained by changing a curve in zone D1 – C1, the coordinates of which are given in Table D.1 which

defines the EPS profile in Annex D (the centre of the 330 mm radius remains fixed).

7.3.4 Zone D0 – B1 (B1a or B1b)

The zone D0 – B1 (B1a or B1b), as appropriate to each profile, remains fixed for each type.

7.3.5 Reverse slope and chamfer

The point B1 of the S1002 profile at the beginning of the reverse slope after the wheel tread is always

situated at 102,158 mm from the internal face of the wheel. The positions of points B1a and B1b of the

1/40 and EPS profiles relative to point B1 are shown below.
