The Railway Procurement Agency (RPA) is to re-examine its preferred options for routing Dublin's Metro North through Ballymun.
The 17km (10.6-mile) metro is set to take passengers underground from St Stephen's Green to Dublin City University (DCU) where it will rise to street level, and pass along the central median on Ballymun Road and Ballymun Main Street.
When the route was announced last month, the RPA said it was considering three options for the Ballymun section. These included an on-street design, an elevated design and putting the line in a trench along the middle of the road.
However, following opposition from locals, The Irish Times understands the RPA has agreed to consider scrapping all three options to continue the metro underground until it has passed Ballymun and possibly the M50.
Labour transport spokeswoman Róisín Shortall revealed senior RPA executives met with local councillors, TDs and executives of Ballymun regeneration this week to work out a solution.
Ms Shortall said there were serious difficulties with all of the original RPA options. In relation to the on-street design, the route would traverse three major intersections in the area of Main Street. " . . . And you cannot have a high-speed train crossing three junctions at the lights," she said.
In relation to the elevated proposal, Ms Shortall said it was impractical to put the train "looking in the first-floor windows of homes" while issues would arise in relation to the space under the line which could give rise to anti-social behaviour.
In relation to the trench proposal, she said there were safety issues for pedestrians and trains. The RPA is to revert to the groups on Tuesday with further proposals.
According to Ms Shortall, a solution which does not involve any of the original three put forward by the RPA is a must if the project is to be successful. "You simply can't spend €3 billion on a high-speed train and then ruin its effectiveness by asking it to stop three times in a short section for junctions with road traffic."
Similarly, she said, it was not realistic to expect people in Ballymun to put up with an elevated or trench section when it could be put underground elsewhere along the route. Metro North is expected to complete its journey from St Stephen's Green to Dublin airport in 17 minutes, arriving at Swords in 26 minutes.
