The original station for
Dún Laoghaire, then known as Kingstown, was situated some closer to Dublin at the West Pier near to or at the present-day
Salthill and Monkstown railway station. That station was the southern terminus of the first railway in Ireland, the
Dublin and Kingstown Railway (D&KR), which opened in 1834. For the first public timetable the station was named
Kingstown but in contract documents it was at least sometimes referred to as
Dunleary. Before the D&KR had even begun to be built it became apparent that the
packet boats were to use either the East Pier or the new wharf being built. Therefore, in 1833 the D&KR raised a parliamentary bill so its railway could be extended beyond the East Pier with a new station at Kingstown, then on to
Dalkey. Mobilised opposition from a rival canal group and local opposition caused the Bill to fail in June 1833. The D&KR regrouped and with lobbying presented a less ambitious bill to the site of the current station only in 1834.
Thomas M. Gresham, a D&KR shareholder and main spokesperson for the opposition, being awarded a silver plate in August 1833 for the same at a personal cost of £1,200, was persuaded not to oppose the 1834 bill. Other obstacles including an agreement to cross the old part of Dunleary harbour and demolition of a Martello fortification needed an agreement with the Admiralty and Ordnance. The bill was passed in May 1834 but logistics meant Dargan began work in May 1836 finishing about a year later. The new terminus opened on 13 May 1837, the first train being a special with D&KR directors and friends. The original station building was an apparently insufficient
Station House and Parcel Office and in 1840 the D&KR resolved to replace it, hiring J. S. Mulvaney as designer. The new station building eventually cost £2,500 and was designed by Mulvaney using
stone quarried in Ballyknockan, County Wicklow in preference to granite from
Dalkey quarry (which was located much closer). The platforms were finally covered in 1845 by a temporary structure costing £122 which was later extended for £300. On 29 March 1844, the
Dalkey Atmospheric Railway officially opened. The line was a branch of the existing D&KR which diverged to the south when approaching from the west with an interchange platform before the atmospheric ran as a single track eastbound into the tunnel. While through running was possible it was not used. Grierson notes that the station build was completed in 1853 to a design by
John Skipton Mulvany by Mr. Roberts doing the "masonry, carpentry, ironmongery, &c," for £1,665. L This included the station walls, while ironwork, roof, and plumbing cost £1,031 by I. & R. Mallet. The roof has since been removed. The station house above the platforms was completed in 1854. a structure in a neo-classical style, designed also by Mulvany. This was the station building until 1971 when the current arrangement was introduced. Mulvany's building became reused as a restaurant. The Dalkey Atmospheric ceased operation in 1854. The
Dublin, Wicklow and Wexford Railway exercised their rights and rebuilt the Dalkey to Kingstown section as a conventional railway at removing height restrictions. When they ran their first train into Kingstown on 10 October 1855, the D&KR directors refused them the use of the station and the passengers were forced to return towards
Dalkey, this also happening for some days afterwards. On 30 March 1856, both the D&KR and D&WR concurred with the D&KR's engineer D. B. Gibbons assessment that the rebuild under
Brunel was not to the parliamentary approved specification in terms and had safety issues and it was closed for rework by
William Dargan as an accident would be disastrous for both companies. Dargan converted the down line between Kingstown and Old Dun Leary harbour to dual gauge so the spoil could be dumped there. and was able to complete the re-work quickly. When the Dalkey-Bray section re-opened on 1 July 1856 the D&KR handed all its operations to the D&WR. The D&WR converted their newly acquired line to in the next year or so enabling through running.
Carlisle Pier with its branch on the single track section just to the east of the station was created in 1859. Although it lay on a
double-track railway for over ninety years, Dún Laoghaire station had only one through platform with a bay platform facing Dublin, both on the seaward side of the station. The station lay on a short section of a single line that ran from just north of the station, to just past the junction for the branch to Carlisle Pier, which was controlled by a signal box known as the 'Hole in the Wall Box.' This arrangement created a bottleneck for intensive steam-hauled suburban services to/from
Bray. It was not until 1957 that
CIÉ remedied the situation by providing a second through platform. Further improvements were carried out in connection with the introduction of
DART electric trains in 1984. A replacement station entrance, with a combined ticket office and automated barriers, was built above the railway lines at street level in 1998. It was constructed with a steel framework supporting a taut sail-like canopy and with glazed panels as side features.
Naming Also called Kingstown Harbour the station was renamed
Kingstown in 1861, and renamed
Dún Laoghaire in 1921. It was given the additional name "Mallin" on 10 April 1966, 50 years after the
Easter Rising, when
Córas Iompair Éireann renamed 15 major stations after
Republican leaders. It is named in honour of
Michael Mallin, a leader in the 1916 Easter Rising. although it is usually referred to simply as Dún Laoghaire. ==Services==
