117. Three viaducts.
Sightseeing in Sydney picture - Apart from traveling behind a huffing and chuffing steam train, struggling noisily up the hill from Bottom Points to Clarence, another high point of the Zig Zag ride is a group of three stone viaducts. All three can be seen here: we are just entering viaduct # 1, wich # 2 and 3 are seen in the background.
