The GWR Rheidol Tanks are a fleet of 2-6-2T steam locomotives of the Great Western Railway design built between 1923 and 1924. They were designed by the railway's Chief Mechanical Engineer, Charles Collett, for working services on the Vale of Rheidol Railway between Aberystwyth and Devil's Bridge (Pontarfynach).
