The National Transport Authority has announced an increase in public transport fares which will come into operation before the end of the year.

The NTA, who approved the rise, say they're doing so to make fares less complicated and to encourage more people to use Leap cards.

The authority said there will be increases in some of the fares for Dublin Bus, Iarnród Éireann, Bus Éireann and Luas.

For Dublin Bus, the schoolchild cash fare is to increase by 5c and by 2c on Leap cards.

The 4-7 and the 8-13 stage bands will be merged for cash-paying adults into one 4-13 band at a €2.70 fare.

This means fares for the previous 4-7 stage will go up 15c from €2.55 and fares for the previous 8-13 stage will be down 10c from €2.80. 

On Iarnród Éireann, some "moderate" fares increases for rail services are planned.

Short Hop Zone fares will increase between 1.4% to 4.2%. 

The price of three-day and seven-day tickets will go up 4%. This move is intended to encourage rail users to use Leap cards.

On the Luas, the one-day, seven-day and 30-day tickets will go up 4%. Again, this change is a bid to drive Leap card use.

Annual and monthly three-zone tickets for the Luas are being withdrawn.

Bus Éireann fares will be restructured to give better discounts to children and students with changes varying from minus 5% to plus 5%.

Anne Graham, CEO of the NTA said that the company wants to "further incentivise people to choose Leap card to pay for their travel – by maintaining a substantial price differential between Leap fares and cash fares."

The fare changes are to be implemented from 1 December, with the exception of a small number in Cork which will only change when the Leap card has been rolled out on certain rail services there.
