Ghost Railways and Lost Villages of the Illawarra

The Illawarra the area south of Sydney, Australia that encompasses towns like Helensburgh, Wollongong, and other nearby towns. The area has an interesting history that goes back to the 1880s. We go looking for the town of Cawley that was a town that sprung up and now has disappeared into the bush. On the way, we came across the old Cawley tunnel and a couple of old viaducts.
