SIPTU says strike action affecting DART services will go ahead, unless plans for new timetables are withdrawn.

Unions representing train drivers are in talks with the company at the Workplace Relations Commission this morning, in a dispute over a new DART timetable with services every 10 minutes.

SIPTU's Paul Cullen says DART drivers will walk off the job if the new schedule is brought in without agreement:

Ciaran Masterson from Irish Rail believes the disruption planned for April 10th can still be avoided:

The dispute began last October when Iarnróid Éireann first proposed increasing frequency on the commuer service.

In response, the National Bus and Rail Union organised a two-hour stoppage, and the plan, which was supposed to begin in January, was postponed to April.

General Secretary of the NBRU Dermot O’Leary, speaking to Newstalk Breakfast, said drivers do not oppose the increased frequency, but wish to be rewarded for the rise in productivity and ensure enough additional staff are hired.

Drivers are heading to the WRC to show their argument has merit, O’Leary said.

"There seems to be a determination to resist all attempts by workers to improve their lot after eight or nine years of austerity," he added.

O’Leary reiterated the union's opposition to scab labour, as Transdev plans to bus Luas commuters from its park-and-ride stops to the city centre.

"If this is the template for the future, then I think we need throw a marker and put it down early. "
