This double-tracked balance incline rose 49 metres from a cramped junction with the Festiniog Railway, passing under the minor road to Dolrhedyn which was carried by a stone bridge, to the drum house at this location. The lower walls of the drum house survive; the drum was 10ft (3.05 metres) long and 6ft (1.8 metres) diameter.
