Transport for London (TfL) has carried out in-carriage noise readings across sites where Pandrol Vanguard is installed on the London Underground network. TfL will continue to take readings at sites where Pandrol Vanguard is installed.

While the noise experienced at higher speeds can be greater than at lower speeds, the relationship between train speed and in-carriage noise is complex, and not consistent. TfL is investigating this relationship and looking at opportunities to balance lower speeds, noise levels and service reliability.
