RMT is balloting all driver members, including Night Tube drivers, on the Jubilee, Central, Northern and Victoria lines, for industrial action against excessive noise levels, which have become intolerable.
The problem is caused by the "Pandrol Vanguard" system LU installed to reduce track noise for people living above and next to the tracks; fair enough, except the system has the effect of forcing the noise into the train itself, leading to thunderous levels of noise in the driver's cab (and, indeed, in the carriages).
LU wants to issue drivers with ear defenders, but RMT is rightly insisting on a long-term engineering fix to sort the problem out properly. As LU won't agree to impose speed restrictions over the affected sections of track, which would alleviate the problem, it is entirely right for drivers to ballot in order to take things into our own hands and impose the speed restrictions ourselves.
The ballot opened today, Tuesday 27 August, and closes on 10 September. Use your vote, vote yes for action!
