Railway transportation is a critical component of global infrastructure which plays significant role in ensuring the safe movement goods and people. In desert environments, effectiveness railway heavily relies on addressing key challenges such as shifting sand, migrating dunes, wind erosion, sand deposition, can disrupt operations increase maintenance costs. To mitigate threats posed by windblown to safety along Lanzhou-Xinjiang High-Speed Railway, technique double rows fences constructed from concrete columns plates has been applied windward side railway. These structures are designed reduce speed capture moving protecting rail infrastructure. velocity their leeward sides 78% 87% for first second rows, respectively. Additionally, due large openings fences, sand-trapping efficiencies 72% row 63% second. The effective shelter distance fence ten times its height. However, advanced technologies like geographic information systems (GIS), geothermal energy solutions, sustainable practices increasingly integrated into these risks enhance reliability. For Etihad GIS techniques were utilized identify areas vulnerable accumulation validate substantial benefits fences. Notably, 40% reduction 74% decrease flux observed post-installation, underscoring disrupting mobility. Specifically, after installation was reduced 40%. threshold transport approximately 0.206 m/s. before 19.95 kg/m2/s, 5.175 kg/m2/s installation, marking reduction. deposition behind over 500 m section around 7387.5 kg/s. This demonstrates that play reducing wind-driven transport, thus accumulation, maintaining operational safety.
