That a station existed here at all speaks to the ambition of Ireland's nineteenth-century railway expansion, which pushed lines into areas that must have seemed, even at the time, optimistic territory for regular passenger traffic. The fact that it has been catalogued as a monument worth recording places it in the same category as ringforts and souterrains, structures considered significant enough to preserve in the national record, even when the surrounding landscape has moved on entirely.

The western counties of Galway saw considerable railway activity from the mid-nineteenth century onwards, with competing companies extending branch lines in search of freight revenue and the occasional tourist. Stations along these routes varied enormously, from modest halts with little more than a timber shelter to more substantial stone buildings with stationmaster's quarters and goods stores. Without more detailed records available, it is difficult to say precisely when the Carrowmoneash station was built, which company operated it, or when it fell out of use. What is clear is that it survived long enough, and retains enough physical presence, to warrant inclusion in the national archaeological record, which suggests at least some structural fabric remains above ground.
