The low-resistance fastener system on bridges widely used in China is mainly WJ-7 type rail fastening systems used on ballastless tracks, while V type rail fastening systems used on ballasted bridges, which can effectively reduce the interaction between the beam and the rail.

The method of to solve the thermal expansion and contraction of steel rails of railway line is generally to use Fastening System to fasten, which is to replace the spring blade fasteners with spring clip fasteners, and fasten the rails tightly on the railway sleepers.

The technical development trends of the China’s rail fastener industry are as follows: (1) The technical level of the industry has been steadily improved. (2) R&D and application of new materials and new processes have become the core of competition.(3) Increased product types and accelerated upgrades.
Barriers in the rail fastener industry in China are as follows: (1) Barriers to market access.(2) Technical barriers.(3) Reputation barriers.(4) Barriers to cooperation.

Anyang Railway Equipment Co., Ltd invented a railway rail fastener with a sand guard. The sand guard passes through the gauge baffle plate, the iron tie plate, the elastic plate and the embedded dowel in the sleeper in sequence, and is manually disassembled and assembled. When the fastener is pulled out of the screw spike, it can prevent the sand near the screw spike from flowing into the threaded hole of the embedded dowel, which improves the efficiency of the maintenance work in the sand accumulation section of the wind area
