RAILWAY NOISE EMISSION ABATEMENT BY APPLICATION OF RESILIENT COMPONENTS TO THE PERMANENT WAY
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2013, Vol 2013, Issue 80
Abstract
The constantly increasing intensity of transport together with the increasing sensibility of population to noise load and air pollutants force the railway route owners and operators to implement effective measures to reduce negative effects of transport on its surroundings. Although the railway traffic is more environmentally friendly than road or aircraft traffic, the modernisation of railway corridors and the increase of the passing train speed causes the increase of the noise emissions, too. This paper deals with the possibilities of abatement of the railway noise emissions directly at the source of the noise by resilient components built in the permanent way. They cause the vibration abatement of the passing trains and influence the transmission and emitation of noise emissions. With the help of the ArcGIS software with the ArcAkus module the noise propagation and the possible abbatement of noise levels after embedding of the rail absorber are simulated in a chosen area of the modernised railway track.
