Eliminating curve squealing of tramways and other rail vehicles - CL-E1

Squeal-less tramways are a reality! Health damaging high frequency squealing has no place in modern cities with ELPA's patented technology.

Product Details



Challenge Area addressed

Pollution Reduction

Tramways, metros or trains that do not squeal. 

Up to 70% reduced emissions of steel dust caused by wear. The air and the underground water will be less poluted with manganese and other heavy metals.

Vibrations in the buildings will be significantly reduced.

The technology built on both required pillars to efficiently manage friction: composite materials and application devices. Together they provide a complete solution that guarantees results reducing friction noise and wear of wheels and rails.

The composite materials contain over 40% of solid particles. The formulas are environmentally acceptable and have been optimised at the inception of the technology.

On the other hand, the application technology has been improving and its unique ability to apply composite materials with on-board and wayside devices. Today the technology is protected with over 30 patents.
