Many residents have complained about the almost continuous (every two or three minutes) extremely loud and prolonged screeching noise coming from the Northern Line near Finchley Central at all hours the tube is operating. The prime source of this noise appears to be the bend in the track north-east of Finchley Central, but also along the tracks that have been replaced, both on the Barnet and Mill Hill East lines. This noise started after the bank holiday engineering works this year, during which Transport for London replaced the track bed with granite ballast, replaced the northbound rails, and installed new concrete sleepers. Automated train operation may be exacerbating the noise as trains approach the corner more aggressively than before. What will you do to tackle this noise which is the result of Transport for London's own works without consideration of the impact on residents nearby?
