The Vale of Llangollen Railway was built as a spur from the Shrewsbury and Chester Railway south of Ruabon to the town of Llangollen. The line was built along the northern side of the Dee Valley and authorized by an act of Parliament, the Vale of Llangollen Railway Act 1859, on 1 August 1859. It was initially opened for goods only on 1 December 1861 and to passenger traffic on 2 June 1862, and was worked from the outset by the Great Western Railway.
