The German prediction method for railway noise from new railway lines was revised by an expert team during the last five years. The draft issue of “Schall 03 2006”[1] is available now. The calculation model is based on octave-band sound power levels describing the emission in different heights of different vehicles, noise sources and parts of noise sources, e.g. roughness of wheels and rails, pantograph noise, and engine noise. The description of sound propagation follows the methods of ISO 9613-2 [2]. The new calculation method allows taking noise reductions into account that are based on technical progress or improvements. To this end, a scheme is described in “Schall 03 2006” [1] for introducing new measures of noise abatement and environmental protection. This includes measures for rolling stock, for rail and track, for bridges, and even measures in the propagation path. The effects of the parameters used in “Schall 03 2006” [1] on noise immission in general and on special existing noise abatement measures, e.g. low noise composite breaks and rail grinding, are presented.
