Carr's Face Quarry and Inclined Tramway

This has to be one of Ireland's most important industrial archaeological treasures. It is the only narrow gauge mineral tramway that we know of in existence in Ireland that has its rail and other features largely intact. The railway was 3ft gauge working on the three-rail principle.

Descending wagons laden with granite blocks provided the force to haul the empty wagons up the steep incline.

A centre rail was common to both and at half way the rails opened out to form two independent passing loops, each with their own rails. After the wagons had crossed they resumed the journey using the common middle rail.

The tramway 'driver' in the drum-house at the top of the incline operated a hand brake on the drum to control the speed of descent of the wagons. The round wire rope was attached to one or more wagons at a length that allowed the wagons to pass at the loop. Normally the wagons were attached to the rope with a sprag (a one-way free-wheel clutch). The rope was endless and was marked showing where sprags were to be fitted. One can only imagine the harsh working conditions for the men who worked at the granite quarry, about which little has been recorded. I believe this has to be an early-mid-C20th enterprise.
