In turn, track ballast typically rests on a layer of small crushed stones: the subballast. The subballast layer gives a solid support for the top ballast, and reduces the seepage of water from the underlying ground. Sometimes an elastic mat is placed on the layer of subballast and beneath the ballast, thereby significantly reducing vibration.
