The output of this remote site was initially taken by horse pack to the quays on the River Conwy at Dolgarrog.
The tramway started at the foot of the quarry exit incline and passed over the Afon Eigiau on a wooden trestle.
Passing the col at Hafod-y-Rhiw the line ran along a series of low stone embankments to the top of a short incline above Coedty.
Below Coedty, and just before the top of the Dolgarrog inclines, the line passed the point where the Cowlyd Tramway was later to branch off.
These were later used as locomotive access by the Eigiau and Cowlyd Tramways, and are today utilized by the two large pipes which carry water to the aluminum works.
