WebJul 11, 2024 · These warps, also known as buckling or sunkinks, can range from small to extreme, turning rail into wavy, serpentine-like tracks. "It’s kind of scary when you look at it," noted Chinowsky.... WebApr 9, 2024 · The expansion of rails can cause the rails to buckle or warp, which can lead to derailments and other safety issues. The decrease in temperature or cooling of the rails causes contraction of the rails. The contraction can result in tensile stresses which in extreme cases can cause fracture of rails due to brittleness and cracks.
