Granulated cork is a practical choice for model railroad scenery because its texture provides a convincing alternative to traditional railroad ballast. The appropriately sized particles are easy to spread along and between the tracks, helping create a uniform and detailed finish. Cork is also lightweight and dimensionally stable, which makes it convenient to work with while building or upgrading a layout. It can help form an even surface around the track area, and because the material spreads efficiently, a relatively small quantity can cover a surprisingly long section of track.
