Incline, Drumhouses and Counter Balances ('A' Incline)

Drumhouses of local rubblestone and slate-slab construction, the latter predominating, each with a gable-ended graded slate roof, that to drumhouse 2 in poorest condition with a number of slates missing at time of Survey. Each drumhouse retains a winding drum and cabling, the double track with rails to the incline itself remaining almost completely in situ. The lower drumhouses (1 and 2) have brakesman's cabins alongside, well-built with fireplaces, the latter having a contiguous office with squint window offering a view of approaching wagons. At this point a stone-walled path leading from Dinorwic down to Llanberis is carried over the incline by means of a cast-iron girder bridge, while the wall bounding the track on its south-western side has heavy slate slabs cantilevered out to provide shelter for the men handling the wagons.
