Iarnrod Eireann has warned customers that a revised timetable will be in operation across the Easter weekend on all routes.
Customers are advised to check times before travel from Good Friday, April 15 to Easter Monday, April 18 as essential works will also mean some diversions over the bank holiday.
The public is also being reminded to pre-book for Intercity travel whenever they can - particularly at busiest times and are asked to wear face coverings on rail services.
