 All commuter rail service runs via Dublin City Centre, and there is no orbital service of any kind.The Western Commuter service was the last to have benefited from significant improvement with the March 2007 opening of the new Docklands railway station in Dublin City Centre, which has allowed for more capacity on the route, not previously possible due to overcrowding at Dublin Connolly.Significant improvements on the Kildare line were undertaken in 2010 which involved quadruple-tracking on the line to allow local traffic to move independently of higher speed InterCity trains.
