The Tanat Valley Light Railway was a 15-mile long standard gauge light railway. It ran westwards from Llanyblodwel in Shropshire, about 5 miles or 8 km south-west of Oswestry. It crossed the Wales–England border and continued up the Tanat valley, terminating at Llangynog in Powys. A small part of it has been restored as part of the Nant Mawr Visitor Centre. Which there are plans to restore the full line as a new heritage railway in the area.
