This route map: view · Irish: DART Faoi Thalamh), previously known as the Interconnector, is a planned railway tunnel in Ireland, projected to run under the city centre of Dublin. The tunnel would allow for the expansion of the electrified DART and the Dublin Suburban Rail network, and connect Heuston Station with Pearse Station. In November 2011 the government announced that the project would be deferred indefinitely.[1]

DART underground would provide an underground link between the existing Northeast DART line between Malahide/Howth and Clontarf Road and the Western Rail line between Heuston and Hazelhatch, with new underground stations at across Dublin's city centre at the Docklands, Pearse Station, St. Stephen's Green, Christchurch, and beneath Heuston Station. The project would also involve the construction of a new overground station at Inchicore.

Specifics

Dublin's existing DART line runs in a north-south along the Eastern seaboard from Malahide and Howth to the North of the city to Bray and Greystones to the south of the city in County Wicklow. The line passes through the city centre by means of an elevated loop line across the River Liffey between Connolly and Pearse stations passing the elevated Tara Street Station on the south bank of the river.

If DART Underground was completed this single-line DART would be replaced by two DART lines forming a rough X and intersecting at Pearse station. The first line would begin in to the north-east of the city in Howth/Malahide following the existing DART line to Clontarf Road but then diverging eastward into a tunnel and to a new underground station in the Docklands and then westward to a new underground station near Pearse Station, under St Stephen's Green (where it would interconnect with the proposed Metro North), Christchurch, and directly beneath Heuston Station. Submerging from the tunnel the line would then continue to a new overground station at Inchicore after which it would follow the existing Commuter line to Hazelhatch to the west of the city.

A second DART line would follow the existing southern DART line from Bray/Greystones to Connolly Station from which it would diverge on the existing but un-electrified line from Connolly to Maynooth to the northwest of the city in County Kildare with a branch off the line at Clonsilla to Pace, County Meath.

Status

In May 2010 the Iarnród Éireann anticipates that, subject to the granting of the Railway Order, that construction could have begun in 2012 and that the tunnel would have been operational by 2018.[2]

On 30 June 2010 Iarnród Éireann submitted an application to An Bord Pleanála for a Railway Order for the scheme under Transport (Railway Infrastructure) Act 2001. Under this Act the Board will consider both planning, environmental and property issues. The granting of a Railway Order would permit both the construction of the scheme and the required compulsory acquisition of property.

In November 2011 the government announced that the project would be deferred indefinitely.[1]

Opposition

There is considerable opposition to the project in Dublin's East Wall area where the tunnel will begin and where tunnelling operations are planned to be located. People also complained that while they will have to endure the disturbance created by the tunnelling works, they will not gain anything from the project as they will not have easy access to a DART station since they are roughly halfway between the existing Clontarf Road station and the proposed Docklands station. Iarnrod Eireann responded, claiming that they can use Clontarf Road Station.[3]
