1023 Kaibab Limestone Ballast O Scale Ballast is a white carbonate sedimentary rock for any railroad that uses white limestone for the railroad.
Like most other sedimentary rocks, most limestone is composed of grains. Most grains in limestone are skeletal fragments of marine organisms such as coral or for Alderamin. These organisms secrete shells made of aragonite or calcite, and leave these shells behind when they die. Other carbonate grains composing limestone’s are ooids, peloids, intraclasts, and extraclasts. We crush it down to make 1023 Kaibab Limestone O Scale Ballast.
Ties/Sleepers are placed on ballast to forms the tracked upon which the track placed. It is packed between, below, and around the ties and ballasted to bear the load from the railroad ties, to facilitate drainage of water, and to keep down vegetation that might interfere with the track structure. The ballast also holds the track in place as the trains roll over it. It consists of crushed stone. Many modelers consider ballasting a chore, but one that is necessary to get the right look.
More on Ballast
The ballast for railway modelers comes in many sizes and colors. You will need to choose the size—this dependent on the scale of your model railway. Choose the color because of the location of your railway. Size is critical as over or under size ballast looks wrong. Color is not as important as variations occurred around the country dependent on what local stone was available. It is possible to combine two colors to create the effect you require, but mixing the materials must be done accurately to allow you to combine the two colors again should you need more material. Choose the size and color that are appropriate for your scale and locale and complement the colors of your scenery.
Track ballast forms the tracked upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and to keep down vegetation that might interfere with the track structure. The ballast also holds the track in place as the trains roll over it. It consists of crushed stone. The term “ballast” comes from a nautical term for the stones used to stabilize a ship.
