Skarloey Slate Quarry

The Skarloey Railway Slate Quarry is a large quarry where all of the Skarloey Railway engines take duties. Engines such as Rusty work there on a regular basis, but in certain instances such as when Sir Topham Hatt closed down Skarloey and Rheneas' line, they were transferred to the quarry. Other visitors to the Slate Quarry over the years have included Elizabeth the Sentinel Lorry.

Since the transfer to larger-scale models for the Skarloey Railway engines, the quarry made more infrequent appearances in such episodes as The Refreshment Lady's Tea Shop and Rusty Saves the Day. It has not been seen since the sixth season.

In the Railway Series, after the copper mines had run dry at Ward Fell, it was found that good slate was available in the foothills. During World War II the Ministry of Defense bought the mines as an ammunition dump.
