Railway applications – Wheelsets and bogies – Part 1: Design method for axles with external journals

Price from:
€ 96.69


Harmonized under:
  • Directive 2008/57/EC of the European Parliament and of the Council of 17 June 2008 on the interoperability of the rail system within the Community (Recast)

Harmonized standards:


This standard:
- defines the forces and moments to be taken into account with reference to masses, traction and braking conditions;
- gives the stress calculation method for axles with outside axle journals;
- specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N defined in EN 13261;
- describes the method for determination of the maximum permissible stresses for other steel grades;
- determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance.
This standard is applicable for:
- axles defined in EN 13261 and
- all gauges1.
The powered axle design method of this standard applies to:
- solid and hollow powered axles for railway rolling stock;
- solid and hollow non-powered axles of motor bogies;
- solid and hollow non-powered axles of locomotives2.
The trailer axle design method of this standard applies to:
- solid and hollow axles of railway rolling stock used for the transportation of passengers and freight that are not consider in the list above;
This standard is applicable to axles fitted to rolling stock intended to run under normal European conditions. Before using this standard, if there is any doubt as to whether the railway operating conditions are normal, it is necessary to determine whether an additional design factor has to be applied to the maximum permissible stresses. The calculation of wheelsets for special applications (e.g. tamping/lining/levelling machines) may be made according to this standard only for the load cases of free-rolling and rolling in train formation. This standard does not apply to workload cases. They are calculated separately.
For light rail and tramway applications, other standards or documents agreed between the customer and supplier may be applied.

1 If the gauge is not standard, certain formulae need to be adapted.
2 In France, the interpretation of the term "locomotive" includes locomotives, locomoteurs or locotracteurs.
