Price increases for Dublin Bus, Luas, Irish Rail and Bus Éireann customers come into effect tomorrow.
On Dublin Bus, adults paying cash will see a 15 cent increase for the 4-13 stop band to €2.70.
On the Luas, one, seven and 30-day tickets will increase by up to 4%.
There will also be increases on some Irish Rail and Bus Éireann services.
The hikes are in an effort to encourage more people to use Leap cards, it is claimed.
