RAILONE Noise Absorber RONA - Noise protection for the ballastless track

Ballastless tracks are particularly efficient roadways that are increasingly used in high-speed or highly frequented routes. Such traffic corridors often also mean particularly high noise pollution for local residents, which should be reduced by suitable measures such as noise barriers. In most cases, these structures are expensive to purchase and maintain or cannot be built due to limited space. The RONA sound absorption lining from RAILONE offers an effective alternative in this regard, especially in combination with other measures. RONA consists of precast concrete elements that effectively reduce sound absorption from wheel-rail contact thanks to their special surface properties and porosity. This can reduce the overall noise level of train traffic by up to three decibels. For this purpose, the prefabricated absorbers are laid over the entire or partial surface of the track. The prefabricated parts are sufficiently secured due to their own weight and therefore do not require any additional fixing to the track, which is why the system can be laid very quickly and efficiently or removed if necessary.
