From 10 October drivers will curb their speed on 28 sections of track spread across the Jubilee, Central, Northern and Victoria lines where the noise is at its most severe.
RMT members on the lines involved will be instructed to drive trains in manual mode at an appropriate reduced speed to mitigate the creation of excessive noise and to alleviate the “distraction, discomfort and anxiety” caused in the affected areas.
Track fastening system Pandrol Vanguard is alleged to be the source of the excessive noise – though described by its manufacturer as “a unique rail fastening system with very low vertical dynamic stiffness” the effects of its use have caused concern to drivers and Transport for London (TfL).
“It is appalling that RMT driver members have had to resort to a programme of industrial action in order to force London Underground to take the issue of excessive track noise seriously,” said RMT general secretary Mick Cash.
“When in Pandrol Vanguard areas on these lines, my members will be instructed to drive trains in manual mode at an appropriate reduced speed to mitigate the creation of excessive noise and to alleviate the distraction, discomfort and anxiety caused in the affected areas.”
London Mayor Sadiq Khan announced in July that TfL was trialling methods of reducing in-carriage noise, including under-rail pads at priority sites.
In addition, TfL said it has already agreed to provide a broader range of ear protection to drivers “who wish to use it” alongside plans for longer-term solutions.
