Ballast Size - Model Railways On-Line - MROL

What size is prototype ballast ? On Britain's railways, prototype ballast is a grade of different stone sizes, ranging from half an inch (12.7mm) to 2 inches (50.8mm), evenly graded. The reason a mixture of sizes is used is so that the stones lock against sleepers and each other to hold track in place without movement.

Railroad Ballast (Rock): Specifications, Sizes, Background

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).
