Greasy rail conditions from leaves, oil or rain reduce traction due to lignin conditions. The wet leaves form a paste on the rails, which then hardens, making it difficult to remove. The buildup causes engine slips when a heavy train cannot gain traction. Dropping sand onto the rails aids in traction for the engine to move forward or stop
Many of our homes require silica sand for glass windows, roofing shingles, insulation, mortar and grouts, and fiber cement siding. Other applications for sand include water filtration, geothermal energy production, metal casting, railroad traction, and a variety of recreational and agricultural activities.
