Hi Dave,I recently bought copies of Oakwood Press"The Farranfore to Valencia Harbour Railway" vols 1&2 by Patrick O"Sullivan. Its a mine of information with many photographs and may provide the info you need. I rather like the station at Cahirciveen,for me its got the lot! Cattle pens, goods shed and siding, single platform & loop, single road engine shed with turntable and a village backdrop.
I also think Bantry on the C.B&S.C. fits the bill but I also like ships!
The downside of both is that large Irish locos ran on neither line but hey its your railway!
Regards Mike
