Rail Fastening System KE HVA (High Vibration Attenuation)

The rail fastening systems KE HVA is designed for category B according to EN 13481-5 standard, with a maximum permissible axle load of 180 kN.

The system is dedicated for Urban Traffic Metros on slab track.

The systems ensure low static stiffness by using resilient pads with high vibration attenuation.
