The main line of the Saundersfoot Railway (nprn 43052) opened in 1832 between Saundersfoot Harbour (nprn 34611) and Thomas Chapel. It was built to a gauge of 4ft 0 3/8in and originally worked by horses. A self-acting incline, some 300m long and on a gradient of 1 in 5, lay about 800m west of the harbour. At the foot was a siding and hut whilst at the summit was a winding house. The track on the incline was double with a shared inner rail, widening to a loop midway allowing wagons to pass.
