The Transport Minister Leo Varadkar says no decisions have been made on whether or not the public will face further price hikes on public transport.
Reports today suggest that CIE will ask the National Transport Authority for a fare increase across bus and rail services.
They are also looking to encourage people to use pre-paid tickets or Leap cards which are cheaper.
Varadkar says there is always a fares review at the end of the year but no hikes are set in stone: "The NTA will make the decision at the end of the year as to whether fares should go up again. That happens every year, no decisions have been made at this stage.
"One thing the NTA has to take into account is the impact this will have on the number of passengers. If you increase them too much, less people use public transport and that defeats the whole purpose."
