Corris Railway. 1966/08/xx, 04. Aberllefenni Quarry was still in use at this time, though only through one adit to the left of the building at the bottom of the incline, the upper levels being closed. The 2' 3" gauge tramway was still used to transport slate to the cutting sheds further down the valley near where the line originally connected to the Corris Railway. Latterly, there being no locomotives, farm tractors were used, straddling the track! August 1966. Slide No. 2384.
