As the Deputy may be aware, the National Transport Authority (NTA) has statutory responsibility for the planning and development of public transport infrastructure in the Greater Dublin Area, including, in consultation with Iarnród Éireann, the planning and implementation of the DART+ Programme covering the Maynooth line.
Noting the NTA's responsibility in this matter and the specific issues raised by the Deputy, I have referred the Deputy's questions to the NTA for a more detailed reply. Please contact my private office if you do not receive a reply within 10 days.
