In the 1860’s the Corris Railway line ceased to deliver slate from the quarries of Corris Uchaf and Aberllefenni direct to shipping and instead transhipped its slate to the standard gauge railway at Machynlleth, in western Montgomeryshire. A semi-official passenger service, using adapted wagons, flourished in the early 1870s. In 1878 the line was acquired by a London company, Imperial Tramways Ltd, and three steam locomotives and ten purpose-built passenger carriages were introduced, although due to a dispute with the quarry owners, passenger services were suspended until 1883. The Great Western Railway purchased the line from Imperial Tramways in 1930 and soon afterwards passenger services were withdrawn. The line continued in use for goods only until 1948 when it became one of the first to be closed by the newly-nationalised British Railways. The line was dismantled soon after closure, the surviving locomotives and rolling stock finding a new life on the nearby Talyllyn Railway
