London Mayor Sadiq Khan has called on Transport for London (TfL) to be more transparent about its efforts to reduce Tube noise, which he acknowledged causes 'misery' for affected residents. The issue particularly impacts areas such as Brent, Kennington, Islington, Camden, and South Wimbledon, where high-pitched screeching from trains on curved tracks can exceed 100 decibels—equivalent to a helicopter taking off nearby.
Labour Assembly Members Push for Action
Labour Assembly Members have been pressing TfL on the noise problem. Elly Baker, Labour’s Transport Spokesperson on the London Assembly, wrote to TfL Commissioner Andy Lord last month demanding clarity on the methodology and success of TfL’s current noise reduction strategy. She noted that a targeted track grinding programme between 2020 and 2022 was replaced by a 'data-led' approach, but since then, the 'frequency and depth of grinding interventions have declined sharply.'
'Since that change, residents affected have reported a clear rise in noise levels,' Baker wrote in a letter seen by the Local Democracy Reporting Service (LDRS). She criticized TfL for not publishing data on the benefits of train coasting, which has been used to reduce noise on some sections, and for providing less detailed information to residents.
Mayor Acknowledges Impact and Announces Funding
On Thursday, Baker asked the Mayor why TfL’s approach appeared to be worsening. Khan responded: 'I recognise the impact that noise can have on people travelling on the Underground and the residents who live in close proximity. The principle cause of track noise is around corrugation, and TfL carries out regular grinding of the track to manage this.'
Khan announced a dedicated rail grinding budget of £9 million for 2025-26, alongside improved grinding efficiency. However, he noted that TfL resources remain constrained despite increased government funding. He added: 'I want to assure Londoners that I understand the significant impact that high levels of Tube noise can have, and that’s why I expect TfL to continue to address all noise complaints with the seriousness they deserve. I’m particularly sensitive to the misery this causes those residents affected by this.'
Demand for Transparency and Data
Baker has demanded 'consistent, specific data on all works carried out for the purpose of reducing Tube noise.' TfL responded that providing monthly updates would be a 'significant logistical challenge' and that long-term plans cannot be shared as approvals are only granted eight weeks in advance.
'I am disappointed by TfL’s slow and piecemeal responses,' Baker told the LDRS. 'This issue spans the whole of London. I want to see a full investigation into the scope of this issue across the city so there can be a fully coordinated approach to tackling it. Residents deserve answers, and they deserve action.'
TfL’s Response and Ongoing Measures
A TfL spokesperson said: 'We understand the importance of minimising noise levels on the Tube itself and in surrounding areas for our customers, staff and neighbours. This is a priority and we are determined to achieve this.' The spokesperson highlighted efforts such as removing insulated rail joints, improving track condition, and a continuous programme of rail grinding and track modernisation. They added that significant noise-related rail grinding had been undertaken in the last six months, along with other targeted interventions.
The Mayor indicated he would ensure TfL provides 'far, far, far more detailed' information to the Assembly and residents. He also noted that TfL is trialling new rail grinding technology and speed variation on certain curves to reduce noise.
