EVS-EN 15827:2025

This document is applicable to the system engineering of bogies and running gear for rail vehicles, including those vehicles intended to operate under the Interoperability Directives.
It specifies the requirements to achieve:
-  a satisfactory design of bogie or running gear,
-  validation of the design within its operating envelope, and
-  a maintenance plan
to ensure that the relevant performance and safety criteria are maintained.
The scope of the system engineering process specified in this document includes the design, validation and maintenance of bogies and running gear. No requirements are specified for other systems components that are attached to the bogies or running gear, except to ensure that a satisfactory interface has been provided.
NOTE  Specifications that relate to bogies and running gear can only be considered in the context of a specific vehicle application. Therefore, the performance, including safety, can relate only to the bogies and running gear as part of a vehicle configuration and not to the individual elements of the bogies or running gear.
