Abstract
The Algerian railway network has undergone significant changes throughout its history, with the Mechria-Ain Sefra-Beni Ounif line playing a crucial role during the colonial era. Despite retaining its importance post-independence, sand accumulation, particularly in the Naama region, has severely hampered railway operations, leading to immense economic losses and decreased public confidence. This study investigates the factors contributing to sand encroachment, emphasizing the impact of desertification, climate change, and human activities. The Oran-Bechara railway line, experiencing frequent service disruptions, serves as the focal point for testing the innovative "Draa" technique—an effective solution incorporating local resources to mitigate sand accumulation. Field assessments revealed that sand from beyond Naama has exacerbated the problem, and the "Draa" technique has shown promising preliminary results in preventing train derailments. Despite challenges, such as material quality and logistical issues, the effectiveness of this method suggests a practical approach for other regions facing similar threats. This study underscores the railway's significance for local populations and highlights the urgent need for sustainable interventions to stabilize railway infrastructure against environmental challenges.
