In 1957 the Northern Ireland Government made the Great Northern Railway Board close much of its network in the province. This left no railways in many rural areas, including the whole of County Fermanagh. By 1958 the GNR main line was the only remaining railway across the border between the Republic of Ireland and Northern Ireland. In that year what was left of the GNRB was dissolved and split between Córas Iompair Éireann (the Republic of Ireland's nationalised transport company) and the UTA.
