Clydach Railroad Section near Brynmawr is a post-medieval and modern tramroad situated in the mineral-rich upland landscape of South Wales. The monument lies upon bedrock of the Millstone Grit Group, a formation of mudstone, siltstone and sandstone laid down during the Namurian period. This underlying geology, part of the South Wales coalfield's productive strata, made the area economically significant during the industrial expansion of the region.
The tramroad represents the transport infrastructure that developed to serve the extraction and movement of coal, minerals and other materials from the valleys and hillsides around Brynmawr. Constructed across challenging terrain, such tramroads were the predecessors to the railway network and became essential to the industrial economy of South Wales. The surviving section preserves evidence of this important phase of transport development, when horse-drawn or gravity-fed systems moved goods along fixed metal or stone tracks.
The monument is protected by Cadw under reference MM263, recognising its significance to the industrial heritage of Wales. The Clydach Railroad Section survives as a physical reminder of the engineering solutions developed to connect the region's mineral resources with markets and consumers, and of the landscape transformation that accompanied nineteenth-century industrial development in South Wales.
