The Rhiwbach Tramway was a Welsh industrial, 1 ft 11+1⁄2 in (597 mm) narrow gauge railway connecting the remote slate quarries east of Blaenau Ffestiniog with the Ffestiniog Railway. It was in use by 1862, and remained so until progressively closed between 1956 and 1976. The route included three inclines, one of which became the last operational gravity incline in the North Wales slate industry. The tramway was worked by horses and gravity for much of its existence, but a diesel locomotive was used to haul wagons on the top section between 1953 and its closure in 1961.
