Irish Rail are once again apologising to customers on commuter routes for continued disruption to services.
In what could be attributed to making the Dublin-Belfast service hourly, customers have voiced anger over delayed and packed services.
These are especially on northern commuter or DART lines.
Timetable changes have happened twice since August and Irish Rail say they got it wrong.
It is advising passengers of a new timetable to come down the tracks from October 14th, it will be published on Monday.
The new timetable includes some commuter services beginning in Bray or Dun Laoghaire instead of at Pearse or Grand Canal Dock.
Some tweaks will me made to Belfast services along with evening commuter times and Maynooth services.
