The station was constructed on an embankment, with the line 25 feet above street level and a Gilbey's bonded spirits store in the undercroft.

[6] Following the accident, the Board of Trade recommended the installation of a facing junction to allow direct access to the goods line, and until that took place all trains were to stop at Ranelagh to ensure that they made a controlled approach to Harcourt Street station.

[8] After the formation of The Great Southern Railways in 1925, Harcourt Street gradually declined in importance as services to the South East were increasingly concentrated on Westland Row (now Pearse) station with goods facilities transferred to the North Wall goods station.

The station continued operating until 31 December 1958, when Córas Iompair Éireann, during its rationalisation programme of the railway network and amid some public criticism, closed the line from Harcourt Street.

[11] The exit was to the station refreshment room which was, unlike most other local licensed premises, permitted to sell alcohol in the holy hour between 2pm and 3pm if customers held tickets for distances over 12 miles, namely Bray and beyond.

Because the embankment which led to the station had been demolished and replaced with new developments, the Luas line diverges from the old alignment at Charlemont and descends a ramp before continuing north on the streets.

It has an island platform - a rarity for Luas stops - which is flanked by tracks running in lanes reserved for trams.
