Rheidol, formerly named Treze de Maio and Talybont, was a 2-4-0T steam locomotive built by W.G. Bagnall in Staffordshire, England, in 1896. Originally built to a gauge of 2 ft 5+1⁄2 in (750 mm), it was for a Brazilian sugar plantation, however the order was cancelled before it was exported. The locomotive was then regauged and renamed for the 2 ft 3 in (686 mm)-gauge Plynlimon and Hafan Tramway, in Wales, where it worked from August 1897 until 1899. It was then regauged and renamed a second time for 1 ft 11+3⁄4 in (603 mm)-gauge Vale of Rheidol Railway,[1] in 1900. It worked on the Vale of Rheidol until 1924, when it was scrapped.
