Iarnród Éireann has warned commuters to book their tickets for the Bank Holiday weekend early as revised timetables, and major works cause significant disruption to travel plans.
Customers should check times before travelling for alterations at www.irishrail.ie or the Iarnród Éireann app and book Intercity travel in advance.
Major works are also taking place, resulting in two significant line closures and alternative arrangements during the weekend.
