The current European Union noise regulations for new or upgraded interoperable rail vehicles came into force in 2002 for high-speed rail and in 2006 for conventional traffic. These standards are known as Technical Specifications for Interoperability (TSI), and are adopted by Commission Decisions. A comprehensive revision of the Noise TSI is planned for 2013. A working group has been established by the European Railway Agency (ERA) who is leading the revision process, where T&E represents the views of environmental groups. This paper is intended as an input to the working group.
