Methodology

EN 50126 · 50128 · 50129 · TSI · CSM-RA · ERTMS/ETCS

Every rail program runs through the same 9-phase CENELEC lifecycle — Concept, Risk Analysis, Requirements, Design, Integration, Validation, Commissioning, Operation, Decommissioning. 30+ gate criteria cover EN 50126 RAMS, EN 50128 SW, EN 50129 signalling, TSI essential requirements, CSM-RA risk evaluation, ERTMS/ETCS baselines, and NoBo / DeBo / AsBo assessment. Built for rolling-stock manufacturers, signalling suppliers, metros, Class I freight, and HSR programs.
