(Main)Railway applications - Requirements for bogies and running gears
General Information
- Abstract
This European Standard consolidates all the separate requirements specified in rolling stock TSIs and European Standards relating to bogies and running gear together into an overall requirement and process that ensures a functional and safe design is achieved for a defined operating envelope.
There are many European Standards that specify the design requirements and associated processes of bogie and running gear components and sub-assemblies. There are also European standards that specify vehicle performance and validation requirements that depend directly on the bogies or running gear. The objective of this standard is to bring all these separate design criteria together. This is accomplished by specifying the design and validation processes to be used for bogies and running gear with particular focus on the two key disciplines of dynamic behaviour and structural integrity. To ensure that safe operation can be continued throughout the product life the definition of a maintenance plan is also required.
This European Standard is applicable to bogies and running gear intended for vehicles that will operate under the Interoperability Directives on designated TEN routes. The requirements, however, can be used in other applications at the discretion of the interested parties. It specifies the requirements to achieve a satisfactory design of bogie or running gear and to validate the design against the relevant performance and safety criteria. Technical requirements are specified directly or by making reference to the relevant European standards and include the nature and content of an auditable record that should be produced of the design and validation processes.
The requirements address only the design and validation of bogies and running gear. No requirements are set for other systems components that are attached to the bogies or running gear, except to establish that a satisfactory interface has been provided.

Overview
EN 15827:2011 - Railway applications: Requirements for bogies and running gear consolidates design, validation and maintenance requirements for bogies and running gear used on rail vehicles. Prepared as a European Standard (CEN), it brings together the separate criteria from rolling stock TSIs and related European standards into a single, auditable process to ensure functional, safe designs for a defined operating envelope (notably for vehicles intended to operate under the Interoperability Directives on designated TEN routes). The standard focuses on the two principal engineering disciplines: dynamic behaviour and structural integrity, and requires a documented maintenance plan to ensure safe operation throughout product life.
Key topics and technical requirements
- Scope and applicability: Applies to bogies and running gear; specifies interfaces but does not set requirements for systems attached to bogies beyond satisfactory interfacing.
- Engineering process: Defines the information flow between vehicle and bogie suppliers and sets out the design and validation process and auditable records.
- Structural design criteria: Load definition (including ultimate, exceptional and fatigue loads), material strength, stability and stiffness requirements, and component structural design (frames, axles, axleboxes, wheels, suspension, attachments).
- Dynamic performance criteria: Acceptance criteria for derailment resistance, running safety, track loading, vibration, noise and ride comfort; numerical simulation and validation routes are addressed.
- Validation and acceptance: Validation plans for structural integrity and dynamic performance, including use of existing validation records and acceptance process flow.
- Maintenance requirements: Mandatory maintenance plan content, inspection intervals, competence and certification of maintenance staff and organisations, traceability and records, unplanned repairs and material disposal.
- Annexes and references: Includes normative annexes on component-related standards, minimum maintenance inspection requirements, standardised bogies for freight wagons, and mapping to EU Directive 2008/57/EC.
Practical applications and who uses it
- Bogie and running gear designers and manufacturers use the standard to structure design, simulation and testing activities and to compile auditable validation records.
- Rolling stock manufacturers and integrators rely on EN 15827:2011 to define interfaces and ensure the bogie meets vehicle TSIs and performance requirements.
- Certification bodies and notified bodies use the standard to assess compliance with interoperability and safety requirements.
- Maintenance organisations and infrastructure managers adopt its maintenance-plan and inspection guidelines to sustain safety and reliability over the life-cycle.
- Operators and procurement teams reference it when specifying vehicle bogie acceptance criteria and proven operating envelopes.
Related standards and compliance
- Integrates requirements from rolling stock TSIs and other European standards for bogie components and vehicle performance.
- Supports essential requirements of EU Directive 2008/57/EC (see Annex ZA of the standard).
- Use in conjunction with component-level EN standards and vehicle TSIs for full compliance and certification.
