Iarnród Éireann is advising customers that intercity and commuter rail services will be at risk from Thursday because of threatened industrial action by SIPTU members in Cork and Mallow.
The services which may be affected are the Cork-Dublin, Kerry-Dublin and Cork-Kerry Intercity services and the Cork-Cobh and Cork-Mallow commuter services.
The threatened strike action arises from the outcome of disciplinary proceedings taken against a Cork ticket inspector for ticketing irregularities.
