Under Sleeper Pads

Trackelast Under Sleeper Pads are provided for Noise & Vibration (N&V) protection. They are also used for Track Quality purposes to improve track stability/performance, minimise track maintenance and preserve track ballast from the effects of attrition.

Trackelast USP’s have been installed in high-speed rail lines as well as Metro / City railways. USP’s are provided to suit all types/shapes of sleepers and track gauges.
