Track ballasting made easy
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. Finally, it keeps the track level and in alignment. The type of material used for ballast varies between railroads.
