There are some places where nature is slowly reclaiming its place. This is an older image from 2013, an abandoned train line located at Helensburgh NSW. Capturing the fall here all comes down to timing. A good solid downpour of rain is needed for at least 24hrs. If you arrive too soon, there will hardly be a trickle, arrive too late and the entire tunnel fills and floods up to the ceiling.
