I propose to take Questions Nos. 618, 619, 623, 635, 636 and 637 together.

Under the Dublin Transport Authority Act 2008, the National Transport Authority (NTA) has statutory responsibility for the planning and development of public transport infrastructure in the Greater Dublin Area (GDA), including the National Train Control Centre, or NTCC. The NTA also manages the wider portfolio of public transport investment nationally.

Noting the NTA's responsibility in this matter, I have referred the Deputy's questions to the NTA for a direct, detailed reply. Please contact my private office if you do not receive a reply within 10 days.
