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 February 23 and 24.
There had been calls for Irish Rail to publish all the remaining dates as soon as possible, but Irish Rail's Barry Kenny says commuters will be given six to seven weeks advance notice.
"The next weekend will be February 23 and 24; we will be giving [the] dates about six to seven weeks in advance in each instance," he said.
"We do have to allow for any impact that weather might have on the ongoing works during the time, but also of course, there's always events on in Dublin so we have to weave our way around those."
