Before the installation of the railway fixing system, the rail plastic dowel is generally pre-buried in the sleeper. Therefore, it can tightly connect the rail fastening system with concrete sleepers and screws or bolts. The elasticity of the plastic makes it more closely connected with iron railway spikes, preventing the loosening of the entire railway fastening system.
In addition, because the rail dowel is a plastic part, it is the same as the rail rubber pads as a railway insulation part, which can realize the electrical insulation of the railway track system.
