NY-GN Rail Fastening System
The NY-GN rail fastening system is specifically designed for railway projects in Mexico and North America, ideal for securing 115RE rails on concrete sleepers.
Elastic clip rail fastening system are widely used in railways worldwide, particularly popular in countries with high-speed rail networks where it plays a crucial role in maintaining track stability and safety. The NY-GN system helps ensure tracks remain securely fastened, reducing the risk of accidents and improving overall railway safety. By minimizing vibrations and reducing noise, the NY-GN fastening system enhances passenger comfort and operational efficiency, making it a preferred choice for modern rail networks.
The complete NY-GN fastening system for each sleeper consists of the following components

Interior Insulator(2 pcs)
-
Exterior Insulator(2 pcs)
-
Rail pad U-2(2 pcs)
-
Insulating bush(4 pcs)
