Given that MN only connects the Maynooth line to Luas Red Line and the Interconnector and that demand at peak times for this connection looks to be less than 100 per peak hour surely a Luas connection from Ballymun in would suffice; with Swords and the Airport served from the Northern Line.

Do you not see any advantage in building a fully segregated metro system that can run trams as often as needed, as long as needed and without any interference from bad driving, congestion, pedestrian conflict, parades or emergency services requiring access to nearby buildings?

What you’re suggesting is adding even more trains to an already over-crowded northern line operated by a very poor company. You’re also suggesting running even more on-street trams which will have more in common with the congested and slow red line than the green line which benefits from an existing right of way.

The system you propose is also limited in it’s expansion possibilities so even if densities improves to the levels you require, the trams can’t be lengthened nor the frequencies increased because of the impact on other street traffic.

Finally, I’m not sure how Irish Rail planned on bringing a heavy rail line above ground into the airport without massive conflicts with the M1, R132 and the airport’s ground transportation system. The station would either be nowhere near the terminal buildings (ala CDG1) or a tunnel would have to be dug to get it underneath the buildings which would have huge cost. Perhaps the whole line from east of the M1 to the terminal would have to be tunnelled and since most of the cost of tunnelling is the entry points, it would be hugely expensive for the distance covered.
