Dart line to be split to make way for underground

DUBLIN'S DART line, which has carried passengers from Howth to Bray for 25 years, is to be severed following construction of the Dart Underground, Iarnród Éireann has confirmed.

The company will next March seek a railway order to construct the new Dart line, which will run underground from the Docklands to Heuston Station and Inchicore via St Stephen's Green.

The underground line, due to open in 2015, will result in the current north-south Dart line being split in two.

Currently Dart trains run from Howth on the north coast of Dublin to Greystones, south of Bray, Co Wicklow, with city centre stops at Connolly, Tara Street and Pearse stations.

Once the underground line is built, passengers travelling from the north side will no longer have direct access to Connolly or Tara Street stations. Their Dart will run as normal to Clontarf Road, but will then enter a tunnel at East Wall and continue to underground stations at Docklands, Pearse, St Stephen's Green, Christchurch, Heuston, and emerging at a surface station at Inchicore.

Passengers heading south will have to change at Pearse to return to the current Dart route.

Southside passengers travelling into the city will still have access to Pearse, Tara Street and Connolly stations. However, after passing through Connolly, their train will turn west, through Drumcondra and out to Maynooth in Co Kildare. To head north on the current Dart line, they also will have to change at Pearse Station.

Presenting the proposed lines to a recent meeting of Dublin city councillors, Dart underground project manager Peter Muldoon said the severing of the current Dart line would not affect journey times.

"If you are going from one side of the city to the other, you will have to change trains; just like every other major city. We hope to have one train every five or six minutes, so the time from leaving your house to arriving at work will not be adversely affected," he added.

Capacity constraints at Connolly Station meant it was not feasible to construct the underground line from Connolly to Heuston stations and preserve the existing north-south Dart line.

"We have a major capacity problem with the tracks coming into Dublin," Mr Muldoon said. "There are a huge number of tracks coming into Connolly and only one track coming out."

The current line capacity at Connolly meant that extra trains could not be added to improve the frequency of the service, he said. The changes would allow a far greater number of trains to move through the city and would ensure passengers had a fully integrated public transport system, which brought them quickly to their destinations.

"This proposal takes people where they want to go - the Docklands and the south inner city. Merely transferring people between Heuston and Connolly doesn't take people where they want to go," Mr Muldoon said.

Iarnród Éireann will begin a new round of public consultation on the line and the proposed stations in the new year before it seeks a railway order, for permission to undertake the project, next March.
