Towards a step-change in new rolling stock certification for noise

Issue 1 2015 / 13 February 2015 /

Noise pollution is an important concern. At a European level the Environmental Noise Directive (END) requires noise mapping of large agglomerations and major routes and the development of Action Plans. It is estimated that 14 million people in Europe are exposed to levels of railway noise above 55 dB Lden, compared with 125 million people for road traffic1. In parallel, regulations controlling the noise emission from individual vehicles have been introduced. For the railway sector these were introduced from 2002 in the form of Technical Specifications for Interoperability (TSI) which limit the noise emission of new vehicles. The latest revision of the Technical Specification for Interoperability (TSI) Noise enters into force in January 2015, and Nicolas Furio, Head of Unit – Technical Affairs at UNIFE, Estelle Bongini, SNCF I&R Acoustics, Vibration and Diagnostics Research Group, and Ulf Orrenius, ACOUTRAIN Technical Leader (Bombardier), provide further information…
