Track ballasting made easy

On model railroads ballast is purely cosmetic, but on real railroads it serves several important purposes. First, ballast holds the track in place and keeps the ties and rails from shifting. Second, it helps drain water away from the track. Third, ballast evenly distributes the weight of the rails and equipment to the subgrade.
