The Green Line re-uses the alignment of the Harcourt Street railway line, which closed in 1958. The Luas stop at Ranelagh is on a stretch of track where the line crosses Ranelagh Road on a viaduct. The Harcourt Street line did not have a station here (a station called Rathmines and Ranelagh was situated further down the line, at the location of the present Beechwood Luas stop). The bridge over Ranelagh Road consists of a steel deck constructed in 2004, and the existing stone abutments.

Ranelagh is one of few Luas stops to have a station building of sorts - a two-storey structure located on Ranelagh Road. The building has a wide entrance, above which is a sign showing the stop's name in the same style as on the platform signs. Inside, the building has little more than tiled steps leading to both platforms. A lift also provides step-free access from the street to the southbound platform. A section of the building is used as a retail unit and is currently occupied by a restaurant. The platforms at Ranelagh are located directly above Ranelagh Road and have the benches, ticket machines, shelters, and displays common to all Luas stops.

Trams stop at the stop coming from either end every 2-10 minutes.

Dublin Bus routes 44/d and S2 serve the stop connecting the stop with areas such as Rathmines and Ballsbridge, as well as further destinations such as Kimmage, Sandymount and Irishtown.
