Donegal stationmaster's house was opened along with the rest of the station on 16th September, 1889. It was built by a separate company from the West Donegal Railway which had run out of money while building its line from Stranorlar through the the Barnesmore Gap, ending abruptly at Druminin about four miles short of its intended destination. Donegal station soon became a junction, the branch line on to Killybegs continuing the route westwards and, subsequently, a southwards branch following the shore of Donegal Bay to the popular tourist town of Ballyshannon. The station house still stands and now houses the Donegal Railway Heritage Centre.
