Cork services will be affected.
Iarnród Éireann has reminded customers of major line works on some routes this weekend.
On Saturday, September 16th, bus transfers will be in operation between Portlaoise and Thurles due to line works, affecting services between Heuston and Cork, Kerry and Limerick.
Services will operate to a revised schedule, and customers are advised to check times and book travel in advance online or via the Iarnród Éireann app.
If you’re Dublin-bound, on Saturday and Sunday, track and overhead line renewal works will take place between Connolly and Dun Laoghaire.
As a result, the following service alterations are in place:
“DART and Commuter: Services are suspended between Connolly and Dun Laoghaire – Dublin Bus and Go Ahead will accept rail tickets. Please use Connolly Station ONLY for city centre, as Tara Street and Pearse Stations are closed.” said a spokesperson.
“Normal DART services will operate between Howth/Malahide and Connolly, and between Dun Laoghaire and Bray/Greystones. Rosslare Intercity: Bus transfers will operate between Dublin Connolly and Bray
“We apologise for the inconvenience caused by these essential works.” they added.
