In 1998 a group of local railway enthusiasts began to explore the viability of preserving as much as possible of the former Tanat Valley Light Railway, which originally operated from Llynclys Junction in England to Llangynog in Wales. They quickly realised the historic importance of the former ‘valley’ line, not only for its multiple connections with other railways in the area (it had connections with both the Cambrian Railway Company and the Shropshire and Montgomery line – The Potts), but also for its position in the evolution of railway transport of the time. The Tanat Valley line was the first cross-border light railway meandering up the fantastic Tanat valley providing links to Llanymynech and Llanfyllin which led the way in opening up the more remote Welsh valleys for both tourism and trade. The TVLR Company is a registered charity which aims to preserve as much as possible of the former Tanat Valley Light Railway system, its associated railway networks and the industrial heritage of the area. In 2004 the TVLR Co acquired a section of disused track bed, which is being restored over its 2 mile length, and leases 25 acres of adjoining land being turned into a multi-themed Country Park for all the family. Our Nant Mawr Visitor Centre is at the terminus of the Potts Line, where visitors can see the Tanat Valley Railway Line, the Nant Mawr Lime Kilns, the Green Stage and the Monorail.
