Who regulates it
Irish rail has its own safety regulator, the Commission for Railway Regulation, which issues safety certificates to operators such as Iarnród Éireann, supervises their safety management systems, inspects after occurrences and licenses train drivers under EU rules. Accidents are investigated independently by the Railway Accident Investigation Unit. The general safety and employment regulators apply too.
Your obligations
Operators must hold a safety certificate from the rail regulator and run an approved safety management system that addresses human and organisational factors, including how tasks and working conditions interact with human limitations. Train drivers must obtain and keep periodic medical and psychological certification. Crew on domestic services follow the ordinary Irish rules: 11 hours' daily rest, breaks, a weekly rest day and an average 48-hour week. Crew on cross-border interoperable services get 12 hours' daily rest at home, at least 8 away from home, a 36-hour weekly rest, and driving capped at 9 hours by day and 8 at night.
Consequences
A rail operator that cannot show its safety management system is working risks the Commission for Railway Regulation restricting, suspending or withdrawing its safety certificate - which stops trains running, a consequence no fine matches. A fatigue-related fitness concern can cost a driver the medical certification behind the licence, and take them off the roster. Breaching the cross-border rail working-time rules is a criminal offence prosecuted in the District Court, and the worker can also bring a complaint. Beyond that, a rail employer faces the same safety prosecutions and working-time awards as any Irish employer.
Penalties
Breaching the cross-border rail working-time rules carries a fine of up to €5,000 on summary conviction, with up to €300 a day for a continuing offence. General safety prosecutions run to €5,000 and 12 months' imprisonment summarily and €3,000,000 and two years on indictment, and working-time compensation can reach two years' pay. The larger rail-specific exposure is commercial: a restricted or suspended safety certificate takes services out of operation.
On the record
No Irish court, coroner, investigator or regulator has published a finding linking fatigue to an incident in rail. In the 2024 Keelogues signal overrun the RAIU examined the driver's fatigue exposure and found it was not a factor.
