There will be no train and dart services into and out of Pearse Street train station in Dublin this weekend.
The station has been undergoing works on the 19th-century roof and repairs which first began in September last year.
This weekend, Saturday and Sunday, both Pearse Street and Tara Street stations will be closed to facilitate the works.
Alternative transfers will be put in place.
The train station is also expected to close for another 12 weekends over the next year and a half due to the works - with the next closure dates to take place on the 23rd & 24th of Feburary.
