Dublin Area Rapid Transit
The Dublin Area Rapid Transit system (stylised as DART) is an electrified commuter rail railway network serving the coastline and city of Dublin, Ireland. The service makes up the core of Dublin's suburban railway network, stretching from Greystones, County Wicklow, in the south to Howth and Malahide in north County Dublin. The DART serves 32 stations and consists of 53 route kilometres of electrified railway (46 km (29 mi) double track, 7 km (4.3 mi) single), and carries in the region of 20 million passengers per year. In a similar manner to the Berlin S-Bahn, the DART blends elements of a commuter rail service and a rapid transit system.
The DART system was established by Córas Iompair Éireann in 1984 to replace an ageing fleet of diesel-powered locomotives. It was, and still is, the only electric mainline railway in Ireland, and one of two currently operating electric railways, the other being the Luas tram which opened in 2004. Since 1987, the service is operated by Iarnród Éireann, Ireland's national rail operator. Contemporary rolling stock on the DART network is powered by 1,500 V DC overhead lines and uses the 1,600 mm (5 ft 3 in) Irish gauge.
The network is being significantly expanded in the 2020s as part of the DART+ project, with future services to run to Drogheda, County Louth, Celbridge and Maynooth in County Kildare and Dunboyne, County Meath.
The section of trackbed between Dún Laoghaire and Dublin City was originally laid out as part of the Dublin and Kingstown Railway, Ireland's first railway. This line was later connected with the Belfast mainline to the north and Wexford mainline to the south and joined the Harcourt Street line at Shanganagh Junction. The scenic views from the railway over Dublin Bay at this point have been compared to those on the Gulf of Naples and have resulted in trips to Killiney Hill and Greystones along the line becoming tourist attractions.
Prior to electrification in 1984, the line was operated using 1950s-era CIÉ 2600 Class rail cars which had been converted in the early 1970s to push-pull operation. These diesel-powered trains were powered by a CIE 201 Class locomotive, with a driving trailer carriage on the other end. This service was notoriously uncomfortable, unreliable, and overcrowded. By the late 1970s, the need for an urgent upgrade to the system had become apparent, as the 2600 Class railcars were in poor condition. Replacement parts had become difficult to obtain due to the age of the rolling stock and its conversion to push-pull operation, which had been intended as a temporary measure until a more permanent solution could be established, had come to the end of its serviceable life.
After studies in the early 1970s, the Dublin Rapid Rail Transit Study, published in 1975, recommended the construction of a rapid transit system with 2 lines: the first one between Howth and 'Ronanstown Centre', a station to be located roughly where Clondalkin/Fonthill is today, and navigating the city centre via a cross-city tunnel; and the second line between Bray and 'Blanchardstown Centre'. The two lines would intersect at an interchange known as 'Dublin Central'. Additionally, branches were to be constructed to serve the suburbs of Ballymun and Tallaght.
The first phase of the project (Howth–Bray) would receive CIÉ approval in 1977, and government approval on 31 May 1979 amidst the 1979 European elections. Linke-Hofmann-Busch would win the contract and supply 40 EMUs, beginning trials in March 1983. Public services began on 23 July 1984 and be inaugurated by Taoiseach Garret FitzGerald on 22 October of that year. The rest of the study would not be implemented reportedly due to a lack of funds.
In conjunction with electrification, three disused stations at Sandymount, Booterstown and Salthill and Monkstown were reopened for the DART in 1984. Sandymount and Booterstown were each built at the sites of a previous station while Salthill and Monkstown was built near the site of the original Kingstown railway terminus, between Seapoint and Dún Laoghaire. As electrification work was undertaken from 1981–1982, a spur which had served the ferry port at Dún Laoghaire was disconnected from the mainline as the installation of overhead power lines to service the harbour would have necessitated the lowering of the track which travelled through a portal south of Dún Laoghaire station.
