Responsibility to develop, procure, implement, operate and maintain the integrated ticketing Leap Card system in the Greater Dublin Area (GDA) became a function of the National Transport Authority (NTA) with effect from 30th September 2010. In addition, section 63 of the DTA Act 2008 extends the Authority’s remit in relation to integrated ticketing to the rest of the State. Noting the NTA's responsibility regarding the issues raised, I have referred the Deputy's question to the Authority for direct reply. Please advise my private office if you do not receive a reply within ten working days.
