Rail & Transit
IRIS Rev.03-aligned rolling stock and rail infrastructure QA.
Quality assurance for rail & transit projects
Rail quality is configuration quality. Rolling stock and signalling assets stay in service for decades, so what matters is that the as-built configuration matches the approved design, and that every change to it is traceable. Our rail work is built around IRIS Rev.03 expectations and the safety-case evidence transit authorities require before revenue service.
Where rail & transit quality typically fails
Fleet variants multiply through the build. We audit configuration management so design changes, concessions and retrofit instructions are reflected consistently in the as-delivered fleet record.
Bogies, doors, traction and interior packages come from tiered suppliers. We conduct IRIS-aligned supplier audits and surveillance at sub-tier level where the criticality justifies it.
Transit authorities require a traceable line from hazard to verification. We structure inspection and test evidence so it maps directly to the safety certification checklist.
