Museum and depot of the Railway Preservation Society of Ireland. Seldom any train rides, but plenty of locos in the sheds and workshops, as well as a replica signal box.
These are a line of basalt sea-cliffs, traversed by a remarkable metal walkway built in 1902. It was the best of several embellishments by railway engineer Berkeley Deane Wise to boost Whitehead as a holiday destination. Early visitors paid 6d to follow it across chasms, caves, tunnels and a sea-stack. It has suffered repeated storm damage and landslip, and is closed in the 2020s. Access is by guided walk in hard hat from the Visitor Centre, from where you're led down a lane to the coast and on to the walkway. It's 5 km there and back, not suitable for anyone with impaired mobility, young children or dogs.
