This document specifies a design assessment procedure of a forged and rolled monobloc wheel (RST). This assessment is carried out before the wheel is commissioned. This document describes, in particular, the assessment to be performed in order to use wheels on a European network which, in addition, have quality requirements in conformity with those defined in EN 13262.
This assessment requires that the conditions of use for the wheel are defined and this standard provides a method for defining those conditions.
The assessment of the design covers four aspects:
- a geometrical aspect: to allow interchangeability of different solutions for the same application;
­- a thermomechanical aspect: to manage wheel deformations and to ensure that braking will not cause wheels to fracture;
- a mechanical aspect: to ensure that no fatigue cracks occur in the wheel web and that no permanent deformation occurs under exceptional loading;
- an acoustic aspect: to ensure that the solution chosen is as good as the reference wheel.
This document does not cover assessment of the hub or of the rim.
This document has been drawn up for wheels of non­powered tread­braked wheelsets and applies in full to this type of wheel. For wheels on which disc brakes are mounted or toothed transmission wheels or even wheels with noise reduction devices, the requirements may be amended or supplemented.
For urban railway vehicles, other standards or documents may be used.

This part of EN 15437 defines the minimum characteristics for the interface between a trackside Hot Axlebox Detector (HABD) and Rolling Stock (RST) that comply with the European Directives for Interoperability to ensure that the minimum functional requirement of the interface is achieved.
The minimum requirements of the interface apply to:
a)   Rolling stock conforming to standard European railway gauge, that is 1 435 mm;
b)   Rolling stock axles fitted with outboard bearings;
NOTE 1   The design of rolling stock axles fitted with inboard bearings should respect the requirements set out in Note 2 of 5.2.
c)   Rolling stock with a maximum design speed lower than 250 km/h;
NOTE 2   Interoperable rolling stock with a maximum design speed higher than or equal to 250 km/h are mandated to have on-board equipment for axlebox condition monitoring. The requirements for on-board equipment are described in !EN 15437-2:2012+A1:2022.
NOTE 3   Interoperable rolling stock with a maximum design speed higher than or equal to 250 km/h are outside the scope of this Part of the standard. However, if such rolling stock are required to be monitored by HABDs their target area should comply with the requirements specified in this standard, except where stated otherwise.
d)   Trackside HABDs that are required to monitor rolling stock with a maximum design speed higher than or equal to 250 km/h.
The rolling stock requirements of the interface are described in Clause 5 and for the HABD requirements of the interface are described in Clause 6.
The scope of this part (part 1) of the standard does not include:
-   Hot Wheel (Hot Disc) Detectors (HWDs). However, HWD are often installed in combination with trackside HABD to provide a dual monitoring system. This standard does not prevent the use of such a combination;
-   how a HABD measures the temperature and identifies axle box position. This is part of an individual equipment design and not part of the functional requirements of this standard;
-   operational requirements for acting on the information reported by the HABD system;
-   maintenance requirements for HABD systems.

This European Standard defines the minimum performance requirements of on-board monitoring systems for axlebox condition monitoring by means of temperature measurements.
This European Standard refers to temperature monitoring of the axlebox. However, the design may be such that the rolling bearing itself is monitored directly.
The requirements of this European Standard are intended to apply equally to basic monitoring systems for monitoring the axlebox temperature through to more technically complex systems that may employ a combination of mechatronics.
To ensure the compatibility of monitoring systems and the effective monitoring functions, this European Standard defines the requirements in the following areas:
-   equipment and characteristics;
-   monitoring performance;
-   operation and interface.
This part of EN 15437 does not include:
-   systems that do not give an indication to the driver;
-   how an on-board monitoring system is structured and how it measures the temperature and identifies axlebox position. This is considered part of equipment design and not part of the functional requirements set out in this standard;
-   operational requirements for acting on the information reported by the on-board monitoring system;
-   operational requirements for conflict of information between trackside monitoring systems and on-board monitoring systems;
-   maintenance requirements for on-board temperature monitoring systems.

This European Standard:

— 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, EA1T and EA4T defined in EN 13261:2020;
— 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 European Standard is applicable for:
— axles defined in EN 13261:2020
— powered and non-powered axles and
— all track gauges3.
The powered axle design method of this European 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 locomotives.
The non-powered 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 considered in the list above.
This European Standard is applicable to axles fitted to rolling stock intended to run under normal European conditions. Before using this European 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 wheelset axles for special applications (e.g. tamping/lining/levelling machines) may be made according to this European Standard only for the load cases of free-rolling and rolling in train formation. This European Standard does not apply to the loads induced by the vehicles in their working mode. They are calculated separately.
This method can be used for light rail and tramway applications.

This part of the European Standard identifies the information required or recommended to be marked on coaches, motive power units, locomotives and On Track Machines, relating to their technical and operational characteristics. It defines the characteristics of these markings, the requirements pertaining to their presentation, their shape and position on a vehicle and their meaning. Some markings are accompanied with note(s) where appropriate.
Service markings relating to passenger information are not addressed by this standard.
The provisions of this standard cover external markings on vehicles as required by:
