On my way into Dublin yesterday I was noticing - again - how great the DART line is. Can there be a more beautiful commuter rail line on Earth? No, not the trains, the scenery along the line - particularly between Bray & Dalkey. I snapped this from the train, which explains the vaguely murky haze - the windows were slightly less than clean.
This (below) is the view you see when you emerge from the tunnel just beyond Dalkey on the way out of town.
