innovative reduction of rail noise
Calmmoon Rail is a highly innovative and effective rail web noise protection system. The Calmmoon sheets convert sound waves into heat by molecular friction - an entirely new approach to solving the problem of noise reduction for railway tracks. The effect may be compared to a small noise insulation panel installed directly on the rail.
2008 - in collaboration with koocoo, the efficiency of Calmmoon Rail is enhanced by 50%.
2009 - detailed product analyses are carried out in practical use on the ÖBB Austrian rail network.
2011 - field trials on 2 Deutsche Bahn projects
2012 - Deutsche Bahn and BMVI (German Federal Ministry of Transport and Digital Infrastructure) publish investigation report KPII demonstrating that Calmmoon Rail, with an average 3 dB noise reduction, is the most effective system for rail web noise damping.
2012/13 - improved technology for maintenance works
2012/13 - field trials on maintenance works in Germany and Holland
2015 - field trials in Switzerland on a test section of BLS AG
In April 2010 the German EBA (Federal Railway Authority) grants approval for operational trials on the German rail network.
In March 2011 Deutsche Bahn issues a positive user declaration.
2018 sees the final approval by the EBA.
