Question to the Department for Transport:

To ask Her Majesty's Government what plans they have to ensure that HS2 Ltd’s Noise Model is verified for accuracy against other domestic and international High-Speed Rail services.

The local and route-wide sound, noise and vibration effects arising from the operation of HS2 were set out in the Environmental Statements for Phase One and Phase 2a. The predictions used in the assessments were based on noise and vibration models extensively validated against measurements of existing high-speed trains in the UK and abroad and supplemented with reasonably foreseeable worst case assumptions about the noise emitted by HS2 trains. Both Houses scrutinised such effects before passing the High- Speed Rail (London to West Midlands) 2017.
