This document specifies the characteristics of wheelsets for all heavy rail track gauges.
This document is applicable to heavy rail vehicles and is applicable, in principle, to other vehicles such as urban rail vehicles.
This document is applicable to wheelsets made from elements defined by the following standards:
- EN 13262:20251 for wheels;
- EN 13261:2024 for axles.
The requirements defined in this document are applicable to cylindrical wheel seats. Most of the requirements are also applicable 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. Most of the requirements are also applicable to wheelsets with inboard bearings. If needed, specific requirements for inboard bearings wheelsets are defined in the technical specification.
Some characteristics are given according to category 1 or category 2.
