Dundrum Luas stop is built on the same site as a former heavy rail station of the same name.

[7] For many years, Dundrum was served as the destination for boarding students attending St Columba's College in Rathfarnham over two miles away.

The route chosen for the Green Line re-used the old Harcourt Street alignment between Charlemont and Sandyford Stillorgan, and Dundrum station was rebuilt as a Luas stop.

The surviving station building was not affected by construction, and remained at the side of the stop for many years in its derelict state.

[9] Dundrum has the same facilities as the majority of stations along the Luas Green line, sheltered benches, ticket machines, signs, and time displays.

[citation needed] The stop has four entrances and exits: a pathway that leads from the southern end of the southbound platform to Taney Drive, a staircase adjacent to Dundrum's Main Street (a pedestrian subway links both these entrances for those wishing to avoid the stop altogether).

[citation needed] A lift provides step-free access from the northern end of the northbound platform to an open area at the side of the crossroads.

This area was laid out so that bus services can connect with the Luas, and the entrance is marked with a sign of the same style as those on the platforms.

The stop is also served by Go-Ahead Ireland routes S6 and 161, providing connections to areas such as Templeogue, University College Dublin and Whitechurch, as well as further destinations such as Rockbrook, Blackrock and Firhouse.
