Ballast: Ballast is material like broken stone, gravel or any other granular material spread and packed below and around sleeper. It provides good drainage for the track structure, It provides weed of greed, It holds sleepers in correct position by preventing movements caused by lateral load therefore ballast is used in the railway track.

The rails secure to the roof by a type of bolt or screw, with flashing installed around/over the hole for a watertight seal. Rail-less systems are self-explanatory—instead of attaching to rails, solar panels attach directly to hardware connected to the bolts/screws going into the roof. The module's frame is essentially considered the rail.

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
