Irish Rail is operating a reduced timetable for the Bank Holiday weekend starting from this morning.
Necessary works are taking place along lines across the country with numerous bus transfers in place.
Extra security will be deployed on services to ensure that only people who need to travel can take the train.
Jane Cregan is a spokesperson from Irish Rail - she outlines the disruption.
"We have a revised schedule in operation on all routes for the Easter weekend.
"We would recommend all intending customers who are travelling to check their times before they travel on IrishRail.ie.
"We do have some engineering maintenance works happening over the weekend also."
