"Track Buckling" aka "Sun Kink", is caused by thermal expansion, a natural property of materials that expand when heated. As the air temperature rises, steel rails can heat up to 50°C (122°F) and much more. Since steel expands when it gets hot, and rails are often held rigidly in place, the built-up thermal stress has nowhere to go. Instead of growing longer, the track buckles laterally usually at its weakest or most flexible point. 📐 Thermal expansion (ΔL) is described by: ΔL = α × L × ΔT α –

Track buckling is when train tracks bend or shift out of place, often during hot weather, because metal rails expand when they get too warm. If the rails don’t have enough room to expand, they can bend and create wavy shapes. Factors like high temperatures, weak or worn track fastenings, and poor maintenance increase the risk of buckling. Fast-moving or heavy trains can also add stress, making buckling more likely. Since this can lead to derailments, rail operators monitor track temperatures clo

Track buckling happens when heat causes rails to expand, bending or shifting tracks. Poor maintenance and heavy trains increase risk. This can lead to derailments, posing serious safety hazards. Rail operators monitor temperatures,inspect tracks, and slow trains during extreme heat to prevent accidents. . Credit: unknown All rights and credits reserved to the respective owners.
