outlined how ballast was to be renewed between Hazelhatch and Kildare, which was to allow running on the long stretch. Further upgrades such as the removal of level crossings and bridge replacements are expected to bring journey times from Cork to Dublin to under 2 hours. The line is expected to be fully electrified by 2030. Dublin congestion Iarnród Éireann's ambition to increase both service speed and service frequency is limited by capacity issues at Dublin Connolly. The Loopline Bridge that links Connolly with Dublin Pearse is a two track route that is currently operating at the limit of its capacity, while Connolly is also used as the terminus for a number of InterCity and Commuter services. 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. 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. The DART Underground project was shelved in 2011, and, as of 2021, not scheduled for any development or funding until "after 2042". Other services The three counties in Ulster that are part of the Republic of Ireland, Donegal, Cavan and Monaghan, are the only counties with no railway connection at all. The closest railway station to Donegal is Londonderry Waterside in Northern Ireland, while the closure of several of the cross-border lines by the Northern Ireland Government led to Cavan and Monaghan losing their rail services in the 1960s. Iarnród Éireann and the government have both been criticised for not considering a restoration of the railway to Donegal, with Donegal County Council stating their commitment to bringing about a return of the rail network to the county by connecting Letterkenny to both Sligo and Derry, to maximise the "Gateway Status" awarded to the three towns.
