Slightly South and East of the former Abersychan and Talywain signalbox see image 41491, the Eastern Valley line passed behind the top of the impressive retaining wall on the left. Just West of Pentrepiod halt, a branch dropped down to the North of the main line, and passed through this short wide tunnel - known locally as Big Arch, latterly used by road vehicles as well as rail. The branch served the British Iron Works, which closed in 1889; and Blaenserchan Colliery, which closed in 1985. View looks East.
Location: British Ironworks (former)
