Description
12303 Union Pacific Tan Granite Sand & Gravel supplies 12303 lbs of a mixed-size aggregate blend, engineered to replicate the sand and gravel routinely used by Union Pacific on mainline and branch‐line right-of-ways. Sourced from naturally weathered granite deposits, this material features a warm tan palette with subtle brown and ochre flecks. The gradation spans from fine powder up to coarse gravel (approximately 1/4″), providing realistic texture and prototypical drainage characteristics under track and alongside ballast shoulders. Each bulk pallet is screened to remove excessive fines, ensuring cleaner handling and minimal dust. When applied on roadbeds, drainage swales, or ballast shoulders, this sand & gravel mix resists erosion and mimics the appearance of full-scale trackside aggregates. Whether you’re outfitting a large outdoor G scale layout, reinforcing embankments on a garden railway, or stocking supplies for multiple HO and O scale modules, Armballast 12303 delivers professional-grade Union Pacific authenticity, consistent color fidelity, and long-lasting stability across every section of track.
Features:
- Color: Warm tan with brown & ochre flecks
- Packaging: Single 16oz bag
- Composition: Naturally weathered granite with mica and quartz inclusions
- Dust Content: Screened to minimize fines and airborne particles
- Drainage: Excellent prototypical water flow and erosion resistance
Application Instructions:
- Grade and prepare the roadbed, embankment, or drainage area to desired profile.
- Spread the sand & gravel mix evenly, allowing particles to settle into low spots and between ties.
- Lightly spray with water to help finer grains nest, promoting interlock among gravel fractions.
- For permanent installation or outdoor use, gently pour a diluted white-glue-and-water mixture (50/50) along edges to secure material without over-saturation.
- Allow to cure for 24 hours before trimming excess or applying additional scenic elements.
What is 12303 Tan Granite Sand & Gravel made out of
Decomposed granite forms over thousands of years when solid granite bedrock weathers and breaks down into smaller particles through natural processes like freeze-thaw cycles, water erosion, and chemical reactions. This weathering typically occurs in regions with exposed granite outcrops—such as mountainous or desert landscapes—where water and temperature changes gradually fragment the rock. The resulting material retains much of granite’s mineral composition, including quartz, feldspar, and mica, giving it a distinctive tan, pink, or gray hue. Because it compacts well and drains easily, decomposed granite is often harvested for landscaping, pathways, and model railroad ballast.
