 The current Docklands station was built to ease the congestion at Connolly by providing an alternate terminus for Commuter services to the M3 Parkway.IÉ's plan initially involved the rebuilding of Dublin Broadstone to serve as a terminus for Commuter services to the west of the capital.However, in March 2008, the Government decided that the track bed leading from Liffey Junction would be used for an extension to the Luas rather than for heavy rail.
