 The DART Underground project was deferred until at least "the other side of 2030".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.
