Sodor Slate Quarry is a quarry located just south of the Blue Mountain Quarry on the north slope of Shane Dooiney. It first appeared in the twelfth season. Mavis has been known to work here.
Trivia
- The quarry shares the same set used for Anopha Quarry.
- Since Thomas and Diesel bashed 'Arry and Bert through the back of the shed, it now has rails running straight through it.
