When searching for something else, the following listing on MyHome.ie came up.
It raised red flags immediately as I knew this was not Dungloe Road Station in Donegal. The blurb states that it is the former stationmaster’s house and it is indeed located to the south of the former station complex. However, agents (as the L&BER called them) houses on the L&BER were generally two storey affairs such as was provided at Burtonport (demolished) or at others such as at Meenbannad and at Crolly Station.
I am not convinced that this is a former railway property.
