The monument consists of a tramway leading to a drumhouse and incline from a ruined slate dressing complex at on the top of Cwm Croesor and connecting with further inclines from Croesor Quarry and the former Croesor railway in the valley bottom.

The monument is of national importance for its potential to enhance our knowledge of the development of industrial transportation in the 18th and 19th century. The track bed, bridges, drainage systems, embankments and revetments may all be expected to contain archaeological information in regard to construction techniques and functional detail.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
