This document specifies the characteristics of wheelsets for all track gauges.
This document applies to heavy railway vehicles but may also apply to other vehicles such as light railway vehicles, trams or undergrounds.
This document applies to wheelsets made from elements defined by the following European Standards:
- EN 13262 for wheels
- EN 13261 for axles.
The requirements defined in this standard apply to cylindrical wheel seats. Most of the requirements also apply to wheelsets with conical wheel seats. 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.
