The Trans-Dublin is a railway route serving the city of Dublin and its surrounding areas. The route is used primarily by the DART service, and runs North-South along the east coast of Ireland. The route is divided into two parts over two different railway lines:

The two sections of the route are connected through the centre of Dublin by the Loopline Bridge over the River Liffey between Dublin Connolly and Tara Street.


There is a currently shelved proposal to construct a railway tunnel under the centre of the city, named DART Underground, to connect Dublin Heuston, Dublin Pearse and Docklands. This would be used to create two new DART lines. The Northern section will be diverted away from Dublin Connolly to Docklands and then through the new tunnel calling at new underground stations at Dublin Pearse, St Stephen's Green, High Street and Dublin Heuston, where it will connect with the lines to the south and west of Ireland, terminating at Hazelhatch. The Southern section will continue on its existing route as far as Dublin Connolly, where it will then be diverted via the Western Commuter route via Drumcondra to terminate at either Maynooth or M3 Parkway railway station on the Navan branch.
