The rail fastening system W21 is designed for categoryC and D according to EN 13481-2 standard, with a maximum permissible axle load of 260kN and minimum curve radius of 150 meters.
The system is dedicated for High Speed systems on ballasted track.
This rail fastening system is provided with a rail pad of static stiffness 40 or 70 kN/mm ± 15%.
Due to the mid-loop of the SKL21 clip, which is mounted over the rail foot, this rail fastening solution is characterized by additional flexibility. This eliminates the possibility of overloading the clip arms and their plastic deformation, as well as prevents rail rotation.
- Option to use anti-theft screws with a triangular head
- All components can be pre-assembled at the sleeper factory
