The initial stage of loss of stability of a continuous welded rail (the so-called “track buckling”) is the loss of stability of one of the rails.

When the rail is worn out, the geometric dimensions of its section decrease, and the axial moment of inertia decreases relative to the vertical axis of the rail section, the center of gravity of the section shifts and, thus, the force eccentricity additionally increases. In the area of the rail insulating joint, there is less rigidity, shocks from the passage of the wheel along the rail joint occur, therefore, when the trains move, the rail track is weakened. Because of this, the danger of rail ejection increases. The article emphasizes the need to strengthen it and increase the rigidity of the rail connection, impact strength and strength of composite plates.

The paper provides a qualitative and quantitative analysis of the probability of loss of stability of continuous welded rail.
