How to solve the hot and cold shrinkage of railway rail?
Nov 17, 2017

Railway line solution to the heat bilges cold shrink from the rail is commonly adopted the practice of fastener tighten, is to replace the shell fastener with spring fasteners (also called elastic fasteners), the rail tightly buckled on-orbit pillow, digest forced the heat bilges cold shrink to produce energy, but that there is a problem, is when the heat bilges cold shrink to produce more energy than the adhesion of the sleeper in the unit of distance, it make the rail track, sleeper rail appear distortion in unit range.

To solve this problem, the railways, at a distance in rail waist rail some holes to release the energy produced by the heat bilges cold shrink, and within a certain distance (about 1500 m) reserved rail joint, to assist in the release of heat bilges cold shrink to produce energy, rail, in order to solve the problem of heat bilges cold shrink.
