WebTrack 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 buckle amplitudes ranging from 6"-14" and tangent buckles from 12"-28". Buckles are typically caused by a combination of three Stressing is a rail engineering process. It is used to prevent heat and cold tension after installation of continuous welded rail (CWR). Environmental heat causes CWR to expand and therefore can cause the fixed track to buckle. Environmental cold can lead to the contraction of the fixed railway track causing brittleness and cracks. Before it is installed, the rail is altered by stretching with hydraulic tensors or heated to its stress-free temperature to make these dangerous problems le…
