• Obstruction of drainage paths, leading to water pooling that refreezes and lifts the track bed.
• Blowing snow that buries tracks andd reduces visibility for drivers.

Summer Heat andTrack Buckling

In summer, high ambient temperatures cause steel rails to expand. In continuous welded rail, were joints are minimized, expansion forces are converted into compressive stress. If the track structurs precident lateral resistance, the rail can buckle - suddenly shifting sideways and creating a dangerous misaligninment.
