Expect sections on lifecycle phases, RAMS requirements, performance targets, evidence and verification approaches, and recommended documentation structures. The document emphasizes structured processes for safety justification, quantitative targets (e.g., failure rates), and traceable links from requirements through design, testing, and operation.
In the modern era of high-speed rail and complex urban transit systems, the margin for error in engineering is virtually non-existent. At the heart of ensuring these systems operate without catastrophic failure is BS EN 50126-2
