Addressing Tube noise is a priority for me, and I continue to stress to Transport for London (TfL) the importance of minimising noise levels for its neighbours.

Despite a number of financial challenges, TfL invests approximately £260m a year on London Underground track renewal and maintenance. This includes a continuous programme of rail grinding and track modernisation.

TfL does not record data in the format you have requested. Many of the works carried out to address noise and vibration issues are carried out alongside routine maintenance works. In addition, many of the resources used – including both staff and equipment – are not used exclusively to address Tube noise.

As you will be aware following your meeting with my Deputy Mayor for Transport in July 2019, TfL has carried out a range of works in this area to address Tube noise, including joint removal and sleeper grouting. Rail grinding was also carried out in September 2019, and readings taken by TfL at local properties indicate that this work has had a significant positive impact on noise levels.

TfL continues to monitor this area closely, with further readings due to be taken at local properties in January 2020.
