Railway applications - Vehicle reference masses
This European Standard defines a set of reference masses for specifying the requirements for the design, testing, acceptance, marking, delivery and operation of rail vehicles.
The reference masses defined in this document are as follows:
- dead mass;
- design mass in working order;
- design mass under normal payload;
- design mass under exceptional payload;
- operational mass in working order;
- operational mass under normal payload.
These reference masses are defined with respect to the whole vehicle, but they can also apply to a specific system or component.
The specification of values for tolerances applicable to reference masses is not in the scope of this standard. Tolerances can be required by an application standard.
Additional loadings due to environmental factors, for example snow and retained or absorbed rainwater, are not in the scope of this European Standard.

Overview
EN 15663:2017+A1:2018/FprA2 (CEN) establishes a consistent set of vehicle reference masses to be used when specifying requirements for the design, testing, acceptance, marking, delivery and operation of rail vehicles. The standard defines reference masses for the whole vehicle and allows the same definitions to be applied to specific systems or components. It is intended to support interoperability, consistent documentation and reliable engineering assessments across European railway applications.
Important scope notes:
- The specification of tolerance values applicable to reference masses is not covered by this standard and must be provided by an application standard where required.
- Additional loadings due to environmental factors (for example snow or retained rainwater) are outside the scope.
Key Topics
This standard defines a set of reference masses and related states. Key reference masses include:
- Dead mass - vehicle mass in the "as built" condition without consumables and without staff.
- Design mass in working order (MVD) - mass for theoretical analysis and calculation in the design condition.
- Design mass under normal payload (MND) - expected design mass with normal payload assumptions.
- Design mass under exceptional payload (MXD) - maximum payload considered for exceptional conditions (design only).
- Operational mass in working order - assumed average mass in service (operational condition).
- Operational mass under normal payload - operational-condition mass with normal payload assumptions.
The amendment also introduces the concept of special purpose masses that an application standard may define when technically necessary (for example, maximum braking load specified by a separate application standard).
Applications
EN 15663 is directly relevant for:
- Vehicle designers and manufacturers defining mass states for static and dynamic analyses.
- Test laboratories and acceptance bodies verifying conformity against specified mass conditions.
- Infrastructure and operations teams assessing track loads, axle loads and compatibility with Technical Specifications for Interoperability (TSIs).
Practical benefits include:
- Consistency in mass definitions used across contracts, tests and certification.
- Interoperability with TSIs and EU directives where referenced.
- Clarity for handing over documentation at delivery and during in-service operation.
Related Standards
- EN 17343:2020 - General terms and definitions for railway applications (referenced by EN 15663).
- Technical Specifications for Interoperability (TSIs) - EN 15663 mass definitions are used by TSIs for rolling stock and infrastructure where cited.
For implementation, project and application standards should cite EN 15663 when prescribing particular values or special-purpose mass states, and they must define any tolerances or environmental loadings that are outside the scope of EN 15663.

The SIST EN 15663:2017+A1:2019/kFprA2:2024 standard provides a comprehensive framework for defining vehicle reference masses, a critical component in the design and operation of rail vehicles. This European Standard focuses on key mass categories, including dead mass, design mass in working order, normal and exceptional payloads, and operational mass under varying conditions. One of the strengths of this standard is its thorough classification of reference masses, which aids engineers and manufacturers in establishing clear parameters for vehicle design and testing. By delineating these categories, the document ensures that rail vehicles meet necessary specifications for safety, compliance, and operational efficiency. Additionally, the inclusion of both whole vehicle and component-specific applications underscores the standard's versatility, making it relevant for various sectors within the railway industry. The standard’s relevance is further emphasized by its alignment with regulatory and operational needs, facilitating accurate marking and delivery of rail vehicles. This ensures that all stakeholders, from designers to operators, have a consistent understanding of the mass specifications required for safe operation. However, it is important to note that while the standard delineates reference masses, it does not encompass tolerances or environmental loadings, which are addressed in application standards. This delineation allows for specialization and targeted focus in those areas, ensuring clarity for users. Overall, the SIST EN 15663:2017+A1:2019/kFprA2:2024 standard stands as an essential reference in the railway sector, providing a well-defined structure for vehicle reference masses and underscoring the operational integrity of rail systems.
La norme SIST EN 15663:2017+A1:2019/kFprA2:2024 revêt une importance cruciale dans le domaine des applications ferroviaires, en définissant un ensemble clair de masses de référence pour les véhicules ferroviaires. Cette norme précise les exigences relatives à la conception, aux essais, à l'acceptation, au marquage, à la livraison et à l'exploitation des véhicules ferroviaires, en offrant ainsi un cadre systématique aux professionnels de l'industrie. Les masses de référence définies dans ce document, notamment la masse morte, la masse de conception en ordre de marche, la masse de conception sous charge normale et exceptionnelle, ainsi que les masses opérationnelles, sont détaillées de manière à garantir une compréhension harmonisée et une application correcte. Cela permet non seulement d'assurer la sécurité et l'efficacité des opérations ferroviaires, mais aussi d'optimiser la conception des véhicules tout en respectant les exigences réglementaires en vigueur. L'un des points forts de cette norme est sa capacité à s'appliquer à l'ensemble du véhicule, tout en laissant la possibilité de l'adapter à des systèmes ou composants spécifiques, offrant ainsi une flexibilité essentielle. Bien que la norme ne traite pas des valeurs de tolérances applicables ni des charges additionnelles dues à des facteurs environnementaux, elle établit toutefois les bases nécessaires pour la mise en œuvre de normes d'application additionnelles qui pourraient couvrir ces aspects. En se concentrant sur les masses de référence, cette norme reste pertinente pour les fabricants, les exploitants et les régulateurs, soutenant l'innovation dans les technologies ferroviaires tout en garantissant la conformité aux exigences sécuritaires et opérationnelles. Grâce à son approche structurée et systématique, la SIST EN 15663:2017+A1:2019/kFprA2:2024 s'affirme comme un outil essentiel pour l'avancement des applications ferroviaires en Europe.
