The National Transport Authority has announced fare increases across all of the country's transport operators - Dublin Bus, Iarnród Éireann, Bus Éireann and Luas.

The new prices will come into effect in January and are as a result of the cut in funds to subsidise public transport announced in Monday's Budget.

Dublin Bus will see fares go up by an average of 15%, the authority said today. But customers using the new ''Leap'' smartcard will be able to avail of fares 5% below the cash fares. Dublin Bus had been looking for increases of between 25% and 36%.

Bus Éireann fares will see increases of 5.4% in city and stage coach services. An increase of 5.1% has been approved for weekly ten journey rates on provincial city, commuter and local services, while a 3% increase will be seen on the annual tax saver tickets for these services. Bus Éireann fare have not increased since 2009.

Rail fare increases have also been approved by the Authority, with DART increases on average of 6% and 6.7% on inner commuter services. A discount on cash fares will also be available for Iarnród Éireann customers who use the Leap card.

The authority has also approved fare rises for the Luas service, which is operated by the Railway Procurement Agency. Adult Luas fares will go up by 5.5%, while children's fares will jump by 12.5%. The authority noted that children's fares have not risen since the launch of the Luas in 2004.

The new Leap card - a smartcard card which will operate across all public transport providers - is available from next week.
