Clongriffin, on the extremity of Dublin City's northern suburbs, is a new residential development constructed near the Dublin to Belfast main line between Howth Junction and Portmarnock. As part of the development, a new modern station was opened at Clongriffin in early 2010. The station has four platforms, but only the main up & down platforms are currently in use, with track currently been laid on the down side which will serve as a relief platform for DART services. The booking office is similar to those built at other new Irish Rail stations, with the structure located above the railway line which connects to a road bridge.
