The roofless shell of a carriage shed, c34 metres long, stands on the west side of the Padarn Railway 170 metres south of its former crossing of the B4366 at the village of Bethel. The shed would have provided accommodation for carriages used in workers trains for employees of the Dinorwic slate quarries who lived in the vicinity.
The Padarn Railway was built to the unusual gauge of 4ft (1.22 metres) to carry slate from the Dinorwic Quarries; it was opened opened in 1843 and closed in 1961.
