The Coolong Brick and Terracotta Company originally manufactured clay bricks and the traditional range of terracotta roof tiles, drainage pipes and plant pots. Unfortunately these latter items were replaced by concrete roof tiles and plastic pipes and pots.

The Company modernised its plant and still produces clay bricks and both terracotta roof tiles and paving tiles from a new pit and manufacturing plant located behind the original works.

Rather than demolish the original plant and dispose of the equipment as scrap, the Company chose to operate the plant as a tourist attraction. It also uses the plant for the production of gargoyles, terracotta garden figures and short run items to client specifications.

As another source of income the company refurbished the original 1' 6" gauge pit tramway and now operates it as a tourist railway running through the works and around the rim of the clay pit. The building on the top level was divided into two sections and the museum section now houses a major display of historical photographs and artefacts of the original workings of the pit and the history of terracotta production. The other half of the building is used for short run production.

Attached to the main building on the top level is a workshop. The company uses these facilities to maintain the assortment of locomotives and rolling stock that it owns.

The workers on duty during the period the pit is open to the public are encouraged to wear clothing appropriate for the late 1940's, early 1950's and most staff manage to look the part.
