| Abstract Irish Rail has applied the Bowtie Analysis method and followed the CIEHF White Paper guidance on Barrier Management to analyse the risk from overspeed events on the national rail network. The analysis was performed in the early days of the COVID19 restrictions, requiring a virtual approach to the analysis, rather than the normal face-to-face workshop format. This paper briefly describes the process followed and the results obtained, focusing on the learnings and potential improvements to the process, rather than the technical details of the analysis. These include: at what point in the bowtie development process to include frontline expertise; prioritising threats and consequences identified so that most effort can be focussed on the most important controls; the complexity of degradation factors relating to human performance; and ensuring presentation of the results matches the expectations of the stakeholder community. |
