Below is the submission I made to the National Transport Authority on a proposal to serve the Airport with public transport, you can find more about the consultation here.
I wish to support option C1, which is a combination of HR1 and LR3. This option involves a DART line to the airport from Clongriffin as well as a Luas line from Cabra to the Airport and Swords.
I support the mainline spur from Clongriffin to Airport as the DART network covers much of Dublin and, therefore, this option will bring a lot of people to the airport via the DART network.
I also believe that LR3, the Cabra to the Airport and Swords line, is the best Light Rail option. I think that to fully provide for the airport, both options should be used.
I live in Cabra and getting to Swords from Cabra via public transport currently requires getting into town. This option would make this a lot easier.
However, to reap the full benefits of the Luas line, it should include a stop at Glasnevin Cemetry. This is a massive tourist attraction and with the increasing popularity of genealogy and the development of the visitor centre and redevelopment of the round tower, a LUAS station here would be very important.
