A friend was staying in Clonmel hotel and enquired about directions to the railway station. Answer: "what railway station?": - they were unaware the town had a train service.
Maybe if Irish Rail let people know they existed, then demand might increase: there might even be enough to justify more than the present skeleton service.
Of course if there were a closure announcement then air would be full of cries from local politicians about how the town would die if the line were to close.
