Located in New South Wales, Australia, the Helensburgh rail line services nearly 900 people daily.
Due to slope instabilities along a section of the rail cutting between 46.740km and 47.170km, a rockfall solution was required for protection of the infrastructure and rail users should a rockfall event occur.
Many of the slope instabilities are associated with the presence of significantly large, fractured, or even detached rock boulders along the top edge of the cutting. The block features are likely to fail through sliding rather than bouncing.
