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
- Procedure approval in a fixed plant, approval of additional rail profiles/grades
- Contractor approval (equipment, operators, supervision)
- Production controls: parameter monitoring, weld identification, finishing and documentation
Practical applications
EN 14587-1:2018 is used to ensure welded rails meet consistent mechanical, metallurgical and geometric quality for safe, long-life track performance. Practical applications include:
- Approving a fixed-plant flash butt welding process before commercial production of welded rail strings
- Defining inspection and test regimes for welding production and acceptance
- Guiding production control, finishing and documentation for welded rails intended for track installation
Who should use this standard
- Railway infrastructure owners and asset managers specifying welded rail quality
- Welding contractors and fixed-plant operators seeking procedure approval
- Rail manufacturers, quality engineers and testing laboratories performing weld qualification
- Track engineers and procurement teams referencing compliant welding processes
Related standards
- EN 13674-1 - Rail grades and dimensions (normative reference)
- EN 14587 series Parts 2 and 3 - mobile welding and welding associated with crossing construction
- Relevant nondestructive testing standards (e.g., EN ISO 3452-1) referenced for inspection methods
This standard is essential for organizations involved in flash butt welding of new rails in fixed plants and for ensuring consistent, traceable weld quality across European railway infrastructure projects.

The SIST EN 14587-1:2019 standard presents a comprehensive framework for the flash butt welding of new Vignole railway rails, specifically addressing those with grades R220, R260, R260Mn, R320Cr, R350HT, R350LHT, R370CrHT, and R400HT. The document delineates precise requirements for approving welding processes conducted in a fixed plant environment and outlines the standards for ongoing welding production. One of the notable strengths of this standard is its focused scope, which ensures clear guidelines for the welding of rails that are intended for railway infrastructure applications. By specifying the grades of new rails subject to these standards, the document ensures that these materials meet the requisite performance and safety criteria necessary for operational reliability. This specificity is essential for maintaining the integrity of railway systems, facilitating safe and efficient transport. Another strength is the emphasis on a flash butt welding process. This method is particularly effective for railway applications due to its ability to produce high-quality welds that are crucial for the demanding conditions rails face. As such, the integration of this welding technique within the standard amplifies its relevance, promoting advancements in railway construction and maintenance. The standard also harmonizes with EN 13674 1, which serves to further solidify its foundations within the broader context of railway infrastructure standards. This alignment encourages consistency across welding processes and enhances the overall quality assurance of welded railway components. Overall, SIST EN 14587-1:2019 stands as a vital document in the standardization landscape, ensuring that the welding of railway rails meets stringent performance criteria which are crucial for the safety and reliability of railway networks. Its detailed requirements and focus on modern welding practices underline its significance in the ongoing development of railway infrastructure.
