History

The South Wales Mineral Railway was incorporated in 1853 for a 13-mile cross-country line from the collieries at Glyncorrwg to the docks at Briton Ferry. The route was laid out by Isambard Kingdom Brunel, who was later succeeded by R.P. Brereton. At the Briton Ferry end a double-tracked cable-worked incline 1.5 miles long was required to overcome the steep terrain. The railway opened in 1861 from Briton Ferry to Tonmawr and to Glyncorrwg in 1863. Originally broad gauge, it was converted to standard gauge in 1872. The railway incline was an antiquated concept by the mid C19 and was expensive to operate. The railway was never a financial success, partly due to the vicissitudes of colliery companies in Glyncorrwg who operated the line. In 1908 the line was taken over by the Great Western Railway, who closed the incline in 1910. The lower part of the incline, including the integral bridge adjacent to the former Ynysmaerdy Farm, was subsequently incorporated into Jersey Park, designed by the Borough engineer H. Alexander Clarke and opened in 1925.
