The Llanelly Railway and Dock Company was an early Welsh railway system. It opened its first short line and a wet dock at Llanelly in 1834, and soon went on to build a longer line from Llanelly to serve pits in the Amman Valley, and then on to Llandilo, reached in 1857. The Llanelly company leased and worked the Vale of Towy Railway on to Llandovery, from 1858. Before 1971 many place names had Anglicised spelling. The railway system was slow to convert the names of railway locations. For consistency, this article generally uses contemporary spellings.
