South Wales Mineral Railway (Extension) Estimate of Expense 1860
Incorporated by act of 15 August, 1853, for a line from Briton Ferry Station on the South Wales Railway to Glyncorrwg, Glamorganshire, with a branch from Raglan to Mitchel stone-super-Avon and Forcedwn Colliery. Length, 13 miles. Capital, £85,000 in £10 shares and £28,000 on loan. The Engineer was I. K. Brunel and the line was built to the Great Western broad gauge. The line was not built until after Brunel’s death. After many delays the section from Briton Ferry to Tonmawr opened in June 1861 and this Extension of the line to Glyncorrwg in March 1863. It was converted to narrow gauge in May 1872. It included a cable-worked incline between Briton Ferry and Incline Top. The line went into receivership in 1880 and was then leased to the Glyncorrwg Coal Company who depended on it to ship out their coal. This action cost the Glyncorrwg Coal Company dearly, and they had to increase their share capital from £70,000 to £200,000 in order to accomplish it. It was absorbed by the Great Western Railway on 1 January 1908 and was then worked by the Port Talbot Docks and Railway Company, which itself had been absorbed by the GWR in 1907. Both the South Wales Mineral Railway and Port Talbot company were worked directly by the GWR after 1 January 1922. The section between Briton Ferry and Tonmawr Junction closed on 31 May 1910, after which traffic beyond Tonmawr ran on to the Port Talbot Railway, thereby eliminating the incline. There was never any passenger service.
