Status Open / In progress
Occurrence Operational Irregularity between Ballybrophy and Lisduff, Co. Laois, 28th March 2024
Occurrence Date 28 March 2024

Basis for Recommendation

The investigation identified that whilst the holding track feature on the Mainline CTC workstation was not identified as significant factor in the incident and the behaviour of the system was known by signalmen. The risk of this feature masking a genuine fault or track circuit occupation was not included in training or briefing materials.

Recommendation

IÉ-IM to consider the inclusion in Mainline CTC training and briefing materials information on the holding track feature and the associated risk of overlooking a genuine track circuit occupation or fault.
