- “Then, hard times came. The mines in the hills closed.”
- ―The Narrator, Granpuff
At some point, Bertram was abandoned here and nature overgrew the mine and all the leftover scrap. Many years later, Toby discovered the mine when he took Sir Topham Hatt and his grandchildren exploring.
Whilst on guard one night, Toby found Bertram. Following this, the mines were re-opened as an attraction for visitors on Toby's Branch Line, with a narrow gauge line operated by Bertram. Skarloey and Rheneas occasionally work here and were present for its re-opening. There is also a small station at the mine.
- The building of the new station is also used for Lower Tidmouth, The Old Station, and Norramby Church Station, while the old station building is reused from Logging Halt.
- On the 2014 television series map, the mine is said to be located near Ffarquhar Road and Tidmouth Bay, however there are no Skarloey Railway narrow gauge tracks leading here. It is therefore most likely that Skarloey and Rheneas get to the mines via flatbed on the standard gauge line.
