sonRAIL is a calculation model for railway noise financed and owned by the Swiss Federal Office for the Environment FOEN. The model was developed in the years 2007 to 2009 by an interdisciplinary project team and has been continuously refined ever since (see Project-Milestones and ongoing developments). The calculation model was documented in detail und published in several scientific articles and conference papers. A short introduction in the functionality of the model can be found here. For more details please have a look at the project documentation and the list of references.

An essential part of the model is the emission data base, which has been developed based on an extensive measurement campaign and which will be enhanced in the future.

Since 2012 the emission model of sonRAIL is used for the planning of new railway lines in Switzerland. The emission model will soon be made available as a web application.

The entire model, i.e., the combination of the emission and the propagation model, has been implemented in a geographical information system on ESRI-standard and has been integrated in the Swiss noise database sonBASE. The application has also been made commercially available by LCC consulting under the name D-noise.
