The tunnel was originally built by the Great Southern and Western Railway company to connect Kingsbridge station to the Dublin Docklands,[2] and primarily used for freight. Historically the line had not been used for regular passenger trains, with most traffic through the tunnel being freight or carriages and engines shunted between Connolly and Heuston for maintenance. It had occasionally been used for special passenger services, including traffic for major Gaelic Athletic Association fixtures.[3]

It reopened on 21 November 2016 for regular passenger traffic.[4] These were only weekday peak at launch, with weekday off-peak being added in December 2018. [5]. There are currently no scheduled weekend services.
