The Green Line is currently entirely in the south side of Dublin city. It mostly follows the route of the old Harcourt Street railway line, which was reserved for possible re-use when it closed in 1958. The Red Line and Green Line are not yet connected to each other, with a 15-minute walk between the two closest points.
Construction of Luas Cross City, an extension to the Green Line, began in June 2013. The new section will begin at the current city centre terminus, St.Stephen's Green, will cross the Red Line near the Abbey stop, and continue northwards, terminating at Broombridge railway station. There it will connect passengers using Irish RailInterCity and commuter services. The extension is expected to open in 2017.
