Issue 12 | Noise
Noise emissions are the "Achilles' heel" of rail transport in terms of its environmental effects. Nevertheless, progress has been made by systematically giving consideration to noise issues in vehicle design. The TSI Noise have been in force since 2007, with emission limits applying to new vehicles. However, the difference in terms of noise quality between vehicles complying with TSI and older ones can be substantial even if the non-TSI vehicles were constructed quite recently and have a fairly long remaining lifetime. On the other hand, it is not guaranteed that purely the application of authorisation rules will be sufficient to meet the requirements of strict noise action planning in the future. Therefore, noise is an issue for PTAs.
The actual relevance and definition of noise-related criteria will usually depend on the relevance of noise immissions in the region and on the age and the availability of rolling stock.
