After a 15 km walk down the coast, and a bit inland, from Dublin 3 this particular DART ( Dublin Area Rapid Transit) ) station was the first one I had been in and actually used to get a train ( back up to Dublin 3 ).
The station is just down the road from the center shopping district, has good direction signage, both automated ticket machines as well as a person in a booth and even has a display telling you how long you will have to wait for your next train.
About 2 1/2 Euro, and 25 minutes later, the station in Dublin 3 that I needed, Clontarf Road, was in sight. read more
