 To compensate, the transport minister announced that Iarnród Éireann would be permitted to obtain planning permission to keep Docklands open permanently as the terminus for Maynooth, Navan and Mullingar services, as well as potential services from Galway.The construction of the DART Underground would enable DART services to be spread over two lines, rather than all being routed through Connolly.This would free up slots at Connolly to allow for improvements in the services provided by both InterCity and Enterprise.
