In response to Question 2019/20787 you provided TfL data on noise readings taken from residential properties in Islington. This shows that noise readings from both north and southbound have risen by at least 10 decibels since 2017. What has changed since 2017 to cause this rise?

Transport for London (TfL) focuses on average noise levels calculated from measurements taken in a number of local properties, which provide the most comprehensive understanding of the noise disturbance experienced by residents.

The difference in average noise readings shown in Mayor's Question 2019/20787 is largely explained by measurements being carried out at different properties in 2017 and 2019. In properties where multiple noise readings have been taken (since 2010), the average noise level has decreased by 0.5dB on the northbound track and increased by 1.2dB on the southbound track.

TfL has temporarily suspended its rail grinding programme on the Tube network, in order to focus on safety critical tasks following the outbreak of coronavirus (COVID-19). TfL still expect to start rail grinding on the Victoria line soon after its overall rail grinding programme resumes, including in this area,which should reduce residential noise levels. In the longer-term, TfL is continuing to investigate the feasibility of the use of a new track-fastening product for use in this and other areas. If a trial of this product proves successful, it could then be rolled out to other areas, including between Highbury & Islington and King’s Cross St. Pancras.
