Lateral alignment defects also reduce the track's buckling strength because buckles tend to initiate at alignment deviations. The larger the line defect, the more buckling prone the track will be. Alignment errors must be corrected in hot weather and in early spring when curves tend to realign themselves from a winter "pull … See more Track buckling is formation of large lateral misalignments in continuous welded rail (CWR) track, often resulting in catastrophic derailments. Both curved and tangent tracks are susceptible to buckling with typical curve … See more Illustrations of track buckles are shown below together with the number of buckled track derailments/damage over the past ten years.
