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 can be used in other applications. It specifies the principles and processes to be followed to achieve a satisfactory design of bogie or running gear and to validate the design against the relevant performance and safety requirements. This document specifies detailed technical requirements by making reference to the relevant European standards and 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 authority 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 those aspects of the vehicle performance that are affected by 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 1, covers the general principles associated with the design and validation of a bogie or running gear and the following three Parts cover:
. Part 2: Structural requirements;
. Part 3: Dynamic requirements;
. Part 4: Maintenance requirements.
The additional Parts provide more precise details of how the overall objectives are to be achieved in these important specific areas. This document structure is consistent with the breakdown of disciplines in the associated engineering processes.
