The latest generation of high speed trains can be designed, constructed and operated with a lower noise emission that many existing trains. It is permissible to procure these trains for use in sensitive situations such as highly population regions where the noise impact could result in significant environmental impacts. To ensure that the cost of the noise control is proportionate to the benefit it provides, HS2 has developed a mechanism to incentivize pass-by noise in the Tender Evaluation of its fleet of high speed trains. The benefit has been assessed by estimating the monetized value of quieter trains operating on the new HS2 railway as well as the existing railway lines. This value was then used in the whole life value model developed for the Tender Evaluation to ensure train manufactures have a sufficient incentive to include state-of-the-art noise control measures in the design of the new trains. This approach has been successful in achieving the pass-by noise level set out as envisaged mitigation in the HS2 environmental assessments. The noise benefit of trains that are approximately 4 dB quieter than the national specification for interoperability will be experienced by approximately 320,000 people living near one thousand kilometers of railway.
