Rail services between Kerry and Dublin will be affected by works by Irish Rail this weekend.
The line between Portarlington and Thurles is closed from 2:30pm on Saturday due to a series of track and signalling works.
It means that all services between Dublin and Kerry will be part-replaced by bus transfers and to a revised schedule.
The 5:05 Saturday evening service from Dublin Heuston to Tralee will involve a bus transfer between Portarlington and Thurles.
The 08:30 Sunday morning train between Dublin Heuston and Tralee will involve a bus transfer from Kildare station to Thurles.
