Anopha Quarry, also known as the Ffarquhar Quarry Company or Centre Island Quarry is the quarry at the end of Thomas' Branch Line and Mavis' home. Mavis, Diesel, Rose, 'Arry and Bert work here most frequently.
Toby, Henrietta, and Bertie take the quarrymen to and from the quarry, but unfortunately Bertie can only go up to the quarry gates and the two had a hard time transporting the workmen. The problem was solved after Sir Topham Hatt renovated an old coach called Victoria and joined her with Henrietta and Toby.
There are four passenger trains a day from Ffarquhar for workers at the quarry and freight trains run when required. 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.
As well as mining quarry rock, there is a section of the quarry which mines slate.
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 is not busy. Percy has been known to go there on rare occasions. However, in later seasons, other engines appear to work here frequently, despite not having any sideplates or cowcatchers.
