35mm colour slide showing section of Saundersfoot Railway near Wisemans Bridge, by Dylan Roberts.
At just over 4ft gauge, the Saundersfoot railway was constructed to link several collieries, including Stepaside/Kilgetty Collieries & Ironworks,to Saundersfoot Harbour. It was later extended to serve Reynalton Colliery, and an extension running north from Thomas Chapel leads to an area of tipping. The route includes an incline and a tunnel. A separate line ran between the Harbour and Stepaside Ironworks.
