A risk matrix built to EN 50126's own worked example, live fault-sequence bowtie diagrams, and safety measure requirements linked straight to SIL.
Rather than a generic "typical" risk matrix, SAFOPS's rail template is built to BS EN 50126-1's own Annex C, Table C.9 risk acceptance categories — Severity bands Insignificant / Marginal / Critical / Catastrophic, Frequency bands Frequent / Probable / Occasional / Rare / Improbable / Highly Improbable, and risk categories Negligible / Tolerable / Undesirable / Intolerable. Each new rail project starts from this matrix as a reviewable baseline, adjustable to your own scheme's specific bands.
A fault landing in Tolerable, Undesirable, or Intolerable automatically carries the safety integrity requirement the standard implies for it — so a safety measure requirement is never silently missing just because a category was renamed or a matrix was rebuilt.
Initiating events, preventative and mitigative barriers, and consequences are modelled as interactive bowtie diagrams you can click, drag, and zoom through — hover any barrier to see its zone of influence and open deficiencies directly on the diagram, not in a separate tracker.
