The document summarizes the proposed Metro North project in Dublin, Ireland. It will be a 16.5km rail line with 11km underground and 5.5km at-grade or elevated. There will be 14 stops along the line connecting Swords to the city center and airport. Construction will occur from 2012-2016 in multiple phases to minimize disruption to traffic and businesses.
