A new railway station opened in Dublin's Docklands this morning, becoming the city centre's first new mainline station in 117 years.

Completed three months ahead of schedule and an estimated €4m under budget, the Docklands Station connects the IFSC to west Co Dublin stations such as Castleknock, Ashtown, Coolmine, Broombridge, and Clonsilla.

The new route runs a near hourly service between 7am and 7pm. Iarnród Éireann says it will serve 2,500 new commuters initially, growing to 10,000 as services expand.

The planned extension of the Luas Red Line to Docklands will also offer commuters more options by connecting them to stops like Four Courts, Pearse Station and Abbey Street.

Docklands station is part of the Government's 'Transport 21' investment programme.

The last mainline station to open in Dublin's city centre was Tara Street in 1890.

DART stations have been opened in recent years at Clontarf Rd (1997) and Barrow Street/Grand Canal Dock (2001), in addition to the commuter rail station reopened in Drumcondra in 1998.
