A TRACK fastening system which is alleged to be the source of excessive noise on parts of London Underground has sparked industrial action by the RMT on four deep tube lines.

Pandrol Vanguard is described by its manufacturer as ‘a unique rail fastening system with very low vertical dynamic stiffness that leads to high levels of vibration isolation. The significant reduction of vibration and secondary noise makes it ideal for applications in areas that are most sensitive to these environmental concerns.’

However, its use has caused concern to drivers and TfL. On 19 July this year London Mayor Sadiq Khan told the London Assembly: ‘TfL is currently trialling methods of reducing in-carriage noise, which includes under-rail pads, at priority sites. Further installation work is due to be carried out from August 2019, with assessments due to be carried out by autumn 2019.’

The RMT says since then improvements have been ‘slow’ and has called for temporary speed restrictions to be introduced, without success. A ballot of drivers on the Jubilee, Central, Northern and Victoria Lines has now produced a 95 per cent vote in favour of action.

As a result, from 10 October RMT members on the four 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’.

RMT general secretary Mick Cash said: ‘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. It should never have come to this and the blame lies solely with the employer and their failure to protect the workforce.’

Transport for London told Railnews: ‘We have met the RMT on a number of occasions on the plans we have to tackle Tube noise and look forward to continuing to work with them to find a resolution. The health and safety of our staff and customers is our first priority and we have already agreed to provide a broader range of ear protection to drivers who wish to use it alongside plans for longer-term solutions to this complex issue.’

Pandrol has not yet responded to a request from Railnews for a comment.
