Purpose: to relieve temperature stresses in rail braids during re-bracing of the braids for permanent operation.Design features: sliding gasket is a plate of trapezoidal shape, one of the lateral sides of which is perpendicular to the bases, and the second lateral side is inclined in relation to the bases. Advantages: - laid directly on the sub-rail gasket, without the need to remove it;- gaskets do not require correction when laying, as the trapezoidal shape does not allow the gasket to slip from the working area, therefore additional delays in the work is excluded;- protrusions on both sides of the gasket serve for convenient installation/dismantling and confident control of the installation, do not allow to view and leave the plate under the fixing
