The quarry was used by the Mid Sodor engines during the line's heyday. Following Smudger's failure as a pumping engine, the mines flooded and the railway closed as a result.
Many years later, Phil Aardman, Robert and Michelle Stewart went on an expedition to Mid Sodor with Duke, Sir Handel and Peter Sam. There, Phil discovered the run-down worksite and found it very suitable for ballast excavation. Over the course of the following months, the quarry was put back into service. Standard and minimun gauge rails were added, old rubble and foliage were removed, and a shed was installed. John Hurt found a very old treasure chest here as well, but during it's discovery he blew up a section of rock, trapping Phil and Michelle inside the shed for a short while until they were rescued by Lewis Packard and his machines.
The quarry is currently used by the small railway engines to supply ballast to the entire island and it's railways.
