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… WebJul 19, 2024 · When the temperature hits 40C, rails can reach 60C and expand and buckle. A train travelling fast over rails can hasten that process through the heat caused by …
