Elpa specialises in tribotechnology for rail noise reduction, solving problems with our rail brake anti-noise system, multi-active rail applicators and rail preservers. We are an innovative and experienced team developing systems that solve worldwide railway problems relating to noise, wear and tear, friction, vibrations, jolts, corrugation, maintenance problems, railway working conditions, etc.
Our solutions – supported by revolutionary WONROS™ noise-reduction technology; BREMEX-ANNSYS, a rail brake anti-noise system; and the CL-E1 application systems for rails – are economically efficient and environmentally friendly.
Our revolutionary WONROS technology eliminates noise caused by friction between metal surfaces – e.g. wheels, rails and rail brakes – and also helps preserves them from wearing out. The technology is built around patented multi-active rail preserving systems, special heavy-duty appliances, designed with rail maintenance, vandalism and energy independence in mind. We therefore use special long-lasting, temperature-proof and environmentally friendly composite materials, applied on sources of noise.
Multi active rail preservers
Multi-active rail preservers supported by WONROS technology are effective against:
Elpa's multi-active rail preservers are verified by the TÜV SÜD Rail and SIQ test and certification bodies.
CL-E1 ws – wayside application system for rails
The CL-E1 ws wayside application system for rails is designed for reduction of noise and wear in rail curves on railways, tramways, metros, etc.
Benefits of the CL-E1 ws system include:
Its robust design makes the system efficient against vandalism.
CL-E1 ug has most of the same characteristics as CL-E1 ws. However, it is intended for use in town centres (urban areas), because the underground installation does not obstruct surroundings and therefore can not be subjected to vandalism.
BREMEX-ANNSYS anti-noise systems for rail brakes
During braking, friction between wagon wheels and rail brakes generates disturbing noise. Elpa's BREMEX-ANNSYS system, for use at hump yards, shunting stations, classification yards and marshalling yards, reduces power of noise (squealing) by 99.9%.
The BREMEX-ANNSYS system:
