Noise pollution register for railway systems – railway noise, fixed daytime emissions
This national register, maintained by the Swiss Federal Office of Transport (BAV), records authoritative noise pollution values for the railway network. It provides both emission and immission data, with fixed daytime emission levels (Lr,e) expressed in dB(A). These values serve as the basis for determining permissible immission levels used in noise abatement measures and expansion projects on the rail infrastructure. The register supports technical assessment of railway noise impact across Switzerland, offering a standardized reference for planning and regulatory purposes related to noise control along rail lines. Access to the data is free and does not require authentication.The authoritative railway noise pollution values are defined in the noise pollution register. Both emission and immission values are shown. The fixed emissions Lr,e in [dB(A)] form the basis for determining the permissible immissions as part of noise abatement measures or expansion projects conduct…
