The section between Ruabon and Llangollen was subsequently reopened on 17 December for passenger trains until 18 January after which only freight services ran until 1968 when the line was closed completely.
The section between Llangollen and Bala Junction was abandoned following flooding although a substitute bus service served the stations until 18 January 1965.
A 10 miles (16 km) section between Barmouth Junction and Dolgellau is used as the Mawddach Trail, a cycle route and bridleway, conversion of which was assisted in 1976 when heavy floods washed away most of the remaining ballast.
The trackbed has also been redeveloped at the west end of Corwen and a number of houses and apartments have been built immediately east of Llangollen.
Infringements occur between Llangollen and Acrefair (typically garden extensions and outbuildings) and the cutting through Cefn Mawr is partially blocked following land slips.
