History

The Talyllyn Railway was incorporated by the Talyllyn Railway Act, 28 & 29 Victoria cap cccxv of 5 July 1865. Its primary purpose was to carry slate products from the productive Bryn Eglwys quarry to the Aberystwyth & Welsh Coast Railway at Tywyn. The line was surveyed and engineered by James Swinton Spooner. A gauge of 2ft 3in (0.686m) was adopted. The greatest single obstacle was the gorge of Nant Dolgoch, which was bridged by a viaduct to maintain an even gradient. The railway opened to goods and mineral traffic in July 1866 and passengers in December 1866. Traffic declined from the late 1930s onwards but the railway continued in operation for passengers and goods until 1950, despite the closure of the slate quarries in 1947. Closure and dismantling were held off due to the owner's insistence that the railway should continue to operate during his lifetime. The railway became notable as the first to be rescued from closure by voluntary effort.

Exterior

The viaduct is built of red brick with flush margin-drafted stone dressings. Three segmental spans carried on two tall slightly tapered piers each 10.3m high above a chamfered base, carrying the track 15.4m (50ft 6in) above the water. The centre arch spans 9.2m and the overall width is 2.8m. There is a triangular refuge cantilevered off at mid span, and it has 4 simple horizontal railings threaded through iron stanchions, set on the low parapets. Stone chamfered revetments. The bridge was rebuilt above the arch tops in 1969-1970 and steel bars with square restraining plates set below the parapets.
