"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 –
