Purpose and objectives

The primary purpose of the SN EN 12663-1+A2:2023 standard is to ensure the structural integrity and safety of railway vehicles under various operational conditions. By establishing clear guidelines for the design and construction of locomotives and passenger rolling stock, the standard aims to protect both passengers and cargo from structural failures. It also provides an alternative method for the assessment of freight wagons, ensuring a comprehensive approach to railway vehicle safety. The objectives include enhancing interoperability, minimizing risks associated with structural failures, and promoting adherence to safety standards across the rail industry.

Scope: who must comply

The SN EN 12663-1+A2:2023 standard applies to manufacturers and engineers involved in the design, production, and maintenance of railway vehicles, specifically locomotives and passenger rolling stock. This includes companies within the railway engineering sector, such as rolling stock manufacturers, railway operators, and maintenance organizations. Compliance is essential for entities looking to ensure safety and reliability in their railway operations, minimizing the risk of accidents and enhancing the overall quality of rail services. Companies involved in freight wagon design and construction also benefit from the alternative methods outlined in the standard, making it relevant across various rail industry segments.

How SN EN 12663-1+A2:2023 relates to other standards

The SN EN 12663-1+A2:2023 standard is part of a broader framework of railway safety and engineering standards. It relates closely to:

• EN 15085: This standard focuses on the welding of railway vehicles and components, ensuring high-quality manufacturing practices are maintained.
• EN 50126: This standard addresses the reliability, availability, maintainability, and safety (RAMS) of railway systems, providing a comprehensive approach to railway safety management.
• ISO 9001: While not specific to rail, this quality management standard complements SN EN 12663-1+A2:2023 by establishing a framework for consistent quality assurance in manufacturing processes.

Revision history and current status

The SN EN 12663-1+A2:2023 was published by the European Committee for Standardization (CEN) in 2023, representing the latest revision of the standard first introduced in 2010. The most recent changes include updates to the structural resistance requirements and additional safety considerations to reflect advancements in engineering practices and technology. These revisions ensure that the standard remains relevant and effective in promoting the safety and reliability of railway vehicles in today’s operational environment.
