Yes.
Predicted usage and potential of the Achill, Clifden and Killala lines was way, way more optimistic than even the busiest times each of them ever was.
Investigation of the history of all three shows that the neighbouring MGWR was highly unenthusiastic about them from the earliest suggestions, as the MGWR was well aware they would never break even, let alone turn a profit.
And unfortunately they were right!
In terms of a layout, sticking strictly to the prototype, virtually all stations in all lines would be hard to fit in most people’s attics. In terms of Achill, Newport without viaduct and long western-side cattle sidings, would be as doable as any, while a slimmed-down Achill is doable. Drop one or two of the sidings even, and it becomes a compact enough terminus.
Mulrany could make a compact enough station too - the hotel building is far enough away to ignore, though there’s less operational interest in it, especially since in later days trains crossed at Newport, not Mulrany.
Then theres the planned, but never built, one-platform halt and fish siding at Tonragee - think of a red-brick Dunsandle.
After the line closed, one of these locos ran on the Ballina branch for a while. Another put in a guest appearance at Loughrea, and two were moved to Athlone. During this time, the Athlone-Portarlington branch train was occasionally hauled by one.
