There are four passenger trains a day from Ffarquhar for workers at the quarry and freight trains run when required. At the quarry, there is a shunting locomotive named Mavis owned by the Company. There is only a platform and waiting shelter at the quarry. The stone is used widely on Sodor and on the mainland for buildings because of its hardness.
Toby, the only engine owned by the North Western Railway allowed on the line lawfully because of his cowcatchers and sideplates, brings the workers to the quarry, takes stone back to Ffarquhar, and will help Mavis with shunting when he isn't busy. Percy has been known to go there on occasion.
