The Helensburgh Railway Tunnel in Australia
Today, the old Helensburgh railway tunnel in Australia is framed by trees, shrubs and a waterfall. But back in the early 20th century, it provided a safe passage for trains passing through the hill-like countryside. But the railway was abandoned in 1920 when the local government decided to build a new double lane for its steam locomotives in a brand new location. But visitors were still allowed to pay the old tunnel a visit until a couple of rotten apples decided to vandalize it.
