This document specifies the characteristics of wheelsets for all heavy rail track gauges.
This document applies to heavy rail vehicles and applies, in principle, to other vehicles such as urban rail vehicles.
This document applies to wheelsets made from elements defined by the following European standards:
— EN 13262:2020 for wheels;
— EN 13261:2020 for axles.
The requirements defined in this document apply to cylindrical wheel seats. Most of the requirements also apply to wheelsets with conical wheel seats. If needed, specific requirements for conical wheel seats (e.g. press-fitting curves, geometric dimensions...) are defined in the technical specification.
Some characteristics are given according to category 1 or category 2.
This document specifies the characteristics of axles for all heavy rail track gauges.
This document applies to heavy rail vehicles and applies, in principle, to other vehicles such as urban rail vehicles.
It defines characteristics of forged or rolled solid and hollow axles, made from vacuum-degassed steel grade EA1N1), EA1T1) and EA4T1). For hollow axles, this document applies only to those that are manufactured by machining of a hole in a forged or rolled solid axle.
The requirements defined in this document are applicable for cylindrical seats. Most of the requirements are also applicable for axles with conical seats. Specific requirements for conical seats (e.g. geometrical dimensions of the seats…) are defined in the technical specification.
Some characteristics are given as a function of a category 1 or of a category 2.
This document is applicable to axles that are designed in accordance with the requirements of EN 13103-1:2017+A1:2022.
This document also permits variations of the material characteristics linked to alternative manufacturing processes (e.g. cold rolling, shot blasting, thermal spraying, steel cleanliness, reduction ratio, improved material properties from melting and heat treatment process, etc.).
This document specifies the characteristics of wheels for all heavy rail track gauges.
This document applies to heavy rail vehicles and applies, in principle, to other vehicles such as urban rail vehicles. Five steel grades, ER6, ER7, ER8, ERS8 and ER9, are defined in this document.
NOTE 1 Steel grade ERS8 has been introduced in this document as an optimization of steel grades ER8 and ER9 due to contact fatigue (RCF), taking into account service feedback from Europe, for example, BS 5892-3 in force in the United Kingdom.
Some features are provided as a Category 1 or Category 2 function.
The requirements defined in this document apply to cylindrical bores. Most requirements also apply to wheels with tapered bores. Specific requirements for tapered bores (e.g. geometrical dimensions, etc.) are defined in the technical specification.
This document applies to monobloc wheels in vacuum degassed steel, forged and rolled, with surface treated rims, which have already been the subject of extensive commercial applications on a European network or have complied with a technical approval procedure according to EN 13979-1:2020 to validate their design.
Annex A describes the evaluation process for accepting new materials that are not included in this document.
This document defines the requirements to be met for wheels; the technical approval procedure is not part of the scope of this document.
NOTE 2 A "surface-treated rim" is achieved by heat treatment which aims to harden the rim and create compressive residual stress.
This document:
— defines the various profiles needed to install, verify and maintain the various infrastructures near the infrastructure gauge,
— lists the various phenomena to be taken into account to determine the infrastructure gauge,
— defines a methodology that may be used to calculate the various profiles from these phenomena,
— lists the rules to determine the distance between the track centres,
— lists the rules to be complied with when building the platforms,
— lists the rules to determine the pantograph gauge,
— lists the formulae needed to calculate the infrastructure gauge,
and is applicable for various track gauges.
This document defines the gauge as an agreement between infrastructure and rolling stock, and defines the responsibilities of the following parties:
a) for the infrastructure:
1) gauge clearance;
2) maintenance;
3) infrastructure monitoring.
b) for the rolling stock:
1) compliance of the operating rolling stock with the gauge concerned;
2) maintenance of this compliance over time.
For a given defined gauge, the application of the rules contain in this part 3, associated with useful elements contained in prEN 15273-4, makes it possible to determine the minimum dimensions of an infrastructure. Therefore, this infrastructure is compatible with vehicle gauge having the same designation, and obtained according to rules defined in prEN 15273-2.
Other networks such as urban and suburban may apply the gauging rules defined in this standard but are outside of its scope.
For absolute and comparative gauging, the application of the rules contained within prEN 15273-3, combined with vehicle data defined in prEN 15273-2 in accordance with make it possible to determine the dimensions of infrastructure.
NOTE The rules given in this standard are not applicable to the gauges “S” and “T” referred to in 4.2.3.1. (7) & (8) for track gauge 1 520 mm of the merged TSI Loc and Pass (Commission Regulation N° 1302/2014 of 18 November 2014).
