Erosion in Action, Rock by the Tracks and Train on the Tracks

 

Photo Essay

Have you ever wondered why there are so many rocks by railroad tracks? These rocks are called Track Ballast and placed in between the tracks. Track Ballast is used to stabilize the tracks and keep them from breaking. Some of the Track Ballast has moved on top of the wooden tracks and may find its way into the cracks. This movement is most likely from the incredible shaking that occurs as a train rumbles over the tracks.
