Engineering works will affect services between Portlaoise and Dublin.
Public transport users are facing major disruption this weekend.
Irish Rail services from Galway to Dublin are operating at a reduced capacity due to engineering works between Heuston Station and Newbridge.
Commuters in Athlone, Clara, Tullamore and Portarlington are facing bus transfers both tomorrow and on Sunday on that route.
Some trains are also cancelled tomorrow including the ten past five train from Dublin to Athlone and the half six train from Dublin to Galway.
Meanwhile all services between Portlaoise and Dublin have been cancelled, with similar transfers from Dublin running through Portarlington, Portlaoise and Monasterevin.
Irish Rail is apologising for any distruption caused.
