NY-ES Rail Fastening System
The NY-ES rail fastening system is designed for railway projects in Mexico and North America, specifically for securing 115RE rails on concrete sleepers. This system stands out for its cost-effectiveness, ease of installation and easier maintenance compared to other fastening systems.
Its design ensures that installation and operations are less complex, which contributes to reduced labor and service costs. It is favored for its simplicity, reliability, and ability to maintain the safety and stability of railway tracks.
The complete NY-ES 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)
-
ES spring blade(4 pcs)
-
SL bolt with nut & flat washer 7/8*201(4 pcs)
