Abstract
Some of the issues related to railway noise type testing are discussed and potential improvements to existing procedures are put forward. New and improved methods that also go beyond the scope of type testing are presented that help to characterize and analyze rolling noise more accurately. These methods are indirect measurement of total wheel-rail roughness, the use of an antenna for source location, and two new methods for separation of vehicle and track noise. Most of the work presented has been performed in the METARAIL project, which is focused on developing improved methods for type testing, monitoring and diagnostic methods for railway pass-by noise.
