It introduces the development of varous JBR Railway rail fasteners, include non-lining elastic fastening of ZHBR, modernized lining fastener ZHBR-65P, non-lining screw-dowel fastening ZHBR-65SH, each fastener has its featurers and advantages. Contact with Anyang Railway Equipment to get more information about various railway rail fasteners.

The features of the working conditions of Railway Rail Fasteners for Reinforced Concrete Sub-rail Bases are as follows:
- the area for the transfer of pressure from the rail to the concrete is quite sufficient for the perception of this pressure, its development by linings is not required;
- the rails can be tilted by tilting concrete beds for rails;
- reinforced concrete is sufficiently electrically conductive, so rails, if they serve as electrical circuits, should be isolated from their base;
- a track with a reinforced concrete sub-rail base has high rigidity even in summer, if the fasteners do not provide the necessary elasticity.

Rail joint bolts are also called track bolts, fish bolts, which belong to fasteners for rail joint bars. Rail joints are one of the three weak parts in the track structure. It is the main reason for the long-term troubles to improve the speed and quality of the line. It is the focus of the daily maintenance of the track maintenance department.

The deformation of the composite sleeper is less than that of the sleeper, the deformation is less than permissible deformation;for the composite sleeper, although the load near the force point of the sleeper is bigger than the sleeper, but the gap between the two is less than 2%, basically the same. Therefore, composite sleepers can meet the train in the range of 60~90 km/h safe and stable operation requirements and suitable as a substitute for wooden sleepers.
