position of the rails on the sleepers and promise the reliable connection between the rails and sleepers,
which prevents the vertical and horizontal displacement of the rails and provides certain elasticity for the
rail structure. Thus, fasteners must not only have sufficient strength and pressure, but also have good
elasticity, a certain adjustment ability and good insulation.
