A tramway, marked as such on the 1907 25 inch OS map. It connects the main quarry pit at Abereiddi (now a tidal pool) with the hoppers above the harbour at Porthgain. The section of the tramway at the W nearest the quarry pit connects with the processing works and lift (NPRN 420607) above the pit. Here there are the remains of sleeper beams each about 1.2m long. the trackway itself being about 2.5m wide. Further E the line continues to a water tank (NGR SM8115 3262) where it veers SE and splits into two branches (possibly three) to terminate above the hoppers at Porthgain. There are no surviving rails. Trucks were initially pulled by horses but later by steam locomotives. 30m above OD.
