History

An original structure on The Snowdon Mountain Railway, which was founded as the Snowdon Mountain Tramroad & Hotels Co. Ltd. in 1894 and opened in 1896. The engineers were Douglas and Francis Fox and the line was originally operated by 5 steam locomotives from Switzerland on the rack and pinion system first devised by Dr Roman Abt of Lucerne. Purely recreational in use, the line has always been a major attraction to tourists visiting the area.

Exterior

Railway viaduct comprising 13 skewed round-headed arches rapidly increasing in height to incline, with a further half arch above the natural rock to the top end. Snecked rock-faced rubblestone blocks with heavily tooled ashlar coping and toothed purple brick to arches.
