| Occurrence | Investigation into two near miss events involving track workers at Bray Tunnels |
| Occurrence Date | 11 April 2025 |
It was identified that issues with both the content of rules and procedures and the understanding of these was a contributing factor to both the Bray Tunnel incidents and multiple incidents detailed in USAN 006. The terms Line Blockage and Signal Protection are repeatedly referenced in rules and instructions but are used inconsistently creating potential uncertainty over their use.
IÉ-IM should review and revise its rules and procedures relating to SSOWs (with particular emphasis on simplifying and clarifying the terminology used for Signal Protection and Line Blockages).
IÉ-IM should then clearly define the circumstances in which each SSOW may be selected and implemented.
