Irish rail has issued passengers with a St Patrick's weekend update as there will be some changes made to the regular schedule - along with a number of extra services running.
There will be extra 'late night' DART and commuter trains operating after midnight on Friday to accommodate revellers travelling home from Dublin city after St Patrick's Day celebrations.
However, the St Patrick's Day parade in Dublin could see huge crowds travelling into the city and Tara Street Station will close until 4pm to facilitate Garda crowd management. People travelling on the DART into town before 4pm on Friday must either get off at Connolly or Pearse Stations.
