WebContinuous Welded Rail (CWR) was developed in response to the observation that the bulk of track maintenance work takes place at the joints. As steel production and manufacturing processes improved, the rail lengths installed were progressively increased, and the logical extension of this would be to eliminate the joints altogether. WebContinuous Welded Rail. Even if CWR can potentially provide the smooth ride of train, there are some drawbacks in which track tends to get buckled easily when the rail axial force …

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… WebApr 12, 2024 · Despite stressing the CWR before installation, a rail may still reach its “Critical Rail Temperature” (CRT). This is the temperature of the rail above which buckling may occur. The CRT may be reached due to disturbance of the ballast, track components, or track geometry. For example, the CRT may be reached due to a removal of a rail …
