In response to my question 2021/1936 you stated Deep Tube Reconditioning had been explored for sections of the Victoria Line through Islington where residential noise impacts are particularly bad. Please could you confirm the estimated cost of this option?

Each metre of Deep-Tube Reconditioning, costs approximately £6,500-8,000. If it was carried out on the same area covered by rail grinding, the expected cost of the works would be around £29 million.

Transport for London (TfL) continues to carry out works to address noise and vibration concerns in this area, and in March and April 2021, carried out extensive rail grinding on both the northbound and southbound tracks, which was effective in reducing noise levels.

TfL and I continue to make the case to Government for the long-term funding support that TfL needs following the impact of coronavirus on its finances. Until a funding deal is in place which provides long-term clarity, TfL’s budget for both targeted noise and vibration interventions, and its wider investment in non-safety-critical track renewal and maintenance (which also impacts on noise and vibration issues), remains subject to change.

Given this, TfL’s ability to carry out Tube noise related work – particularly long-term and expensive interventions such as Deep Tube Reconditioning – is currently limited.
