The Llangollen and Corwen Railway was formed as a continuation of the Vale of Llangollen Railway to continue the line along the Dee Valley a further to Corwen. This was opened on throughout on 8 May 1865 and was worked by the Great Western Railway (GWR). It became part of the GWR by the Great Western Railway (Additional Powers) Act 1896 (59 & 60 Vict. c. ccxxxii), and subsequently part of the Western Region of British Railways.
It was closed by British Railways in 1968, but the line survives today, and has operated as a heritage railway since 1981.
