· Ballast also acts as a support base for the railroad track structure giving it strength and rigidity but also allowing for flexibility when trains pass over. Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength. According to Brian Solomon's book Railway Maintenance

· Based on the evidence [8], [9], [10], track buckling can cause derailment and cause a huge loss of assets and can also result in the loss of passenger lives. It is noted that track buckling around the world usually occurs in conventional railway ballasted tracks due to the poor track conditions and lateral misalignment in the rails.

4. Gluing the Ballast. To fix the ballast in place, lightly spray it with a mixture of water and a few drops of dish soap; this helps the glue to seep into the ballast. Then, apply a diluted white glue mixture (50% water, 50% glue) using a pipette or spray bottle. The soap in the water helps the glue mixture flow evenly through the ballast.
