Overview
EN 14587-1:2018 (CEN) specifies requirements for the approval and production use of flash butt welding processes carried out in a fixed plant for new Vignole railway rails. It covers welding of rail grades R220, R260, R260Mn, R320Cr, R350HT, R350LHT, R370CrHT and R400HT of 46 kg/m and above (as defined in EN 13674-1) and is intended for the assembly of rails into welded strings for railway infrastructure. This part supersedes EN 14587-1:2007 and forms part 1 of the EN 14587 series.
Key topics and technical requirements
The standard sets out both process-approval and production requirements including:
Welding process requirements
- Rail end preparation and horizontal alignment
- Clamping force, pre-heating, final flashing and upsetting
- Unclamping, slippage control and welding parameter specification
- Post-weld thermal treatment and removal of excess upset
Quality verification and tests for procedure approval
- Visual inspection, magnetic particle or dye-penetrant testing
- Bend tests, macro- and micro-examination, hardness testing
- Fatigue testing and fracture-face defect recording
- Measurement of weld straightness, flatness and steps across the weld
Approval scope and governance

The standard EN 14587-1:2018 serves a critical role in the railway applications sector, specifically focusing on the welding of new Vignole railway rails. Its primary aim is to establish comprehensive requirements for the approval of a flash butt welding process within a fixed plant environment, as well as guiding subsequent welding production practices. One of the notable strengths of this standard is its precise applicability to specific grades of rails, including R220, R260, R260Mn, R320Cr, R350HT, R350LHT, R370CrHT, and R400HT, all of which are robust options for railway infrastructure. The inclusion of minimum weight specifications (46 kg/m and above) ensures that the standard targets higher performance qualities essential for rail applications. The document provides a clear framework for implementing the flash butt welding technique, which is critical for producing high-quality, durable welds essential for maintaining rail integrity over time. By setting uniform standards for welding processes, EN 14587-1:2018 enhances the reliability of welded strings, thereby contributing to the overall safety and efficiency of railway operations. Moreover, the standard's relevance extends beyond the immediate welding process; it integrates into broader railway infrastructure standards outlined in EN 13674-1, reinforcing the interoperability and consistency of railway components across different jurisdictions and implementations. This integration is vital for ensuring that welded rails meet not just local, but also international safety and performance standards, ultimately fostering greater trust and reliability in railway operations. Overall, EN 14587-1:2018 stands out as an essential reference for manufacturers and operators within the railway sector, addressing specific welding requirements, promoting best practices, and ensuring adherence to quality and safety benchmarks.
