scope:

This document is applicable to bogies and running gear intended for vehicles that will operate under the Interoperability Directives on designated TEN routes. However, the requirements may be appropriate for other applications that have similar operational conditions.
It specifies the principles and processes to be followed to achieve a satisfactory design of bogies or running gear and to validate the design against the relevant performance and safety requirements. This document does not specify detailed technical requirements but identifies the nature and content of an auditable record that shall be produced of the design and validation processes involving the railway undertaking, customer, supplier, approval body and infrastructure controller.
The requirements address only the design and validation of the functional and safety aspects of bogies and running gear whose provision falls within the responsibility of the supplier. They also apply only to the bogies/running gear themselves. No requirements are set for other systems components that are attached to them, except to establish that a satisfactory interface has been provided.
This European standard consists of four Parts. This, Part 2, covers structural requirements.
The other three Parts are:
- Part 1: General principles;
- Part 3: Dynamics requirements;
- Part 4: Maintenance requirements.
This document structure is consistent with the breakdown of disciplines in the associated engineering
processes.
The requirements given in this Part 2 should be applied in conjunction with the requirements of Part 1 and those of Parts 3 and 4 where relevant interfaces apply.
