Active visco-elastic mudslide streams are widely developed along the edges of basaltic flow formations on the Shufan Plateau. Brief orographic, tectonic, and geologic assessment of the area is given. Landslides, revinement, denudation violate the normal transportation rhythm. The results of studying the process conditions and causes are discussed. It is established that the main cause of mudflows is traffic arteries tracing along the low-grade (12-15 degrees) slopes built by unconsolidated clays, with of the clays transformation into plastic state during long drizzles, common in the area, as the principal one. Working out options or engineering protection of railroads against the mudflows at the outskirts of Shufan Plateau has shown that each is highly problematic. Seismotectonic hazard of the regional Lower-Suyfun fault, coinciding with the Razdolnaya River valleyas well as modern vertical movements of the earth crust in the area discussed have to be taken into account while exploring the territory.
