Systems safety and RAMS for transport, delivered as one discipline.
Allegiant Systems is a Melbourne engineering consultancy. We work with transport agencies, project authorities, operators, and contractors who need a safety and reliability case that passes regulator review and still makes sense to the people who maintain the asset.
- Heavy rail
- Tram
- Metro
- Road
When safety and RAMS are bought as separate packages, the conflicts show up late. A hazard control nobody costed. A reliability target never linked to a tolerable hazard rate. A maintenance change that quietly removes a safety barrier.
EN 50126 already treats RAMS as one process with safety inside it. We work that way, so the trade-offs are found at concept and design, when they are cheap to fix.
