    2018-09-28  For many modelers, adding ballast is one of the first steps in the process of creating realistic scenery for your layout. When planning this stage, traditional gray stone gravel will likely come to mind, but take a closer look at real world railroading, and you’ll notice that each railroad and each type of railroad has its own very distinctive look to it.

  • Railroad Ballast, Types And Purpose

    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).
