KZN Rail Damper

Name: KZN Rail Damper
Brand: Longhua Technology Group (Luoyang) Co., Ltd.

The KZN Rail Damper is a rail damping system installed on both sides of the rail web. It effectively attenuates rail vibration, reduces wheel-rail impact noise radiation, minimizes wheel-rail wear, and lowers maintenance frequency. Proven to decrease track noise by over 5dB, it significantly improves vibration attenuation rates and controls rail corrugation. With minimal components and easy installation, it is compatible with various rail fasteners, vibration mitigation measures, and operational conditions—suitable for both new line construction and existing line retrofits.
