1020 Kaibab Limestone Powder 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 1021 Kaibab Limestone N 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.
1020 Earth Ground Cover soil is affected by several different factors. These include: climate, relief, soil drainage. We have this tan earth soil.
