EN 13231-2: Part 2: Acceptance of Reprofiling Rails in Plain Line, Switches, Crossings, and Expansion Devices Standard
The railway industry relies on robust standards to ensure the safety, efficiency, and reliability of rail infrastructure. One such important standard is **EN 13231-2: Part 2: Acceptance of Reprofiling Rails in Plain Line, Switches, Crossings, and Expansion Devices**. In this article, we’ll explore the key aspects of this standard, its technical parts, and its significance in railway engineering.
1. Overview of EN 13231-2: Part 2:
EN 13231-2 is a European standard that specifically addresses the acceptance criteria for reprofiling rails in various railway track elements. It provides guidelines and requirements for assessing the quality and fitness for use of reprofiled rails in plain line tracks, switches, crossings, and expansion devices.
2. Acceptance Criteria:
The standard outlines criteria for the permissible deviations in terms of rail geometry, surface condition, and material properties. It defines limits for parameters such as vertical and lateral profiles, surface defects, hardness, residual stress, and more. These criteria ensure that reprofiled rails meet the necessary safety and performance requirements.
3. Technical Parts:
EN 13231-2 is divided into several technical parts, each focusing on specific aspects of acceptance criteria. These technical parts cover different types of rail sections, including vignole rails, grooved rails, flat-bottomed rails, and switch and crossing rails. Each part provides detailed guidelines for inspecting and evaluating reprofiled rails in those specific applications.
4. Importance in Railway Engineering:
The standard plays a crucial role in maintaining the integrity of rail infrastructure. By establishing acceptance criteria, it ensures that reprofiled rails are fit for use and do not compromise the safety or operational efficiency of railway tracks. Compliance with EN 13231-2 helps engineers and technical personnel make informed decisions about the acceptance or rejection of reprofiled rails, thus minimizing risks associated with rail defects.
In conclusion, EN 13231-2: Part 2 sets forth the acceptance criteria for reprofiling rails in plain line tracks, switches, crossings, and expansion devices. It provides clear guidelines for evaluating the quality and suitability of reprofiled rails, enabling engineers to ensure the safety and performance of railway infrastructure. By adhering to this standard, the railway industry can maintain high standards of track quality and enhance overall operational efficiency.
