Why Modelers Choose ARM Ballast

  • Natural appearance: real stone provides authentic color, texture, and variation.
  • Sizes for popular scales: choose material suited to N, HO, O, or G scale.
  • Colors for many prototypes: match a railroad or select a color that fits your layout’s location and era.
  • More than track ballast: use compatible powders, dirt, gravel, rocks, and other materials throughout the scene.
  • Useful package choices: select the quantity that fits a test section, layout project, club, or larger scenery build.

Not Sure Which Ballast to Choose?

First select the correct size for your scale. Next, choose a color that fits the railroad, region, and era you are modeling. Mainlines often use cleaner, more uniform stone, while yards and older sidings may include darker ballast, cinders, dirt, and weathering.

If you are unsure about a color, begin with a small test section. View the material beside your track, structures, and ground cover before completing the entire layout.

Build the Scene, Not Just the Track

A convincing railroad scene uses more than one texture. Combine ballast with fine soil, sand, gravel, rocks, and powders to blend the track into the surrounding landscape. Slight changes in color and particle size can distinguish a mainline from a yard, an active industry from an abandoned spur, or a maintained road from a dusty service area.
