EU researchers are developing a new noise certification process for freight and passenger trains. Quieter trains are better for the environment, particularly for people living close to railway lines.
Rail travel has a long history of noise control. However, in order to meet the EU's Technical Specification for Interoperability (TSI) on noise, each new railway vehicle must be subjected to necessary but expensive and time-consuming tests.
