Tramroad from Disgwylfa West originally to Nantyglo, but now disappears after approx. 1.6 km north of Hafod. The tramroad is generally well preserved as a 2.0m wide track, grassed and stable and designated as a footpath. The tramroad is 1.0m wide and generally slightly raised 0.2m. At this point the tramroad divides to serve additionally the quarries at Pant draenog and Disgwylfa East.
