Tube drivers plan go-slow action on noise levels
Some Tube drivers are planning to reduce the speed of their trains in protest at "extreme noise levels" they say they are exposed to on the Underground.
Slowing down trains by even a small amount is likely to result in a less frequent service and more crowded services at peak times.
Transport for London (TfL) has confirmed the volume of sound experienced by drivers has exceeded the legal limit and said it was working to resolve the issue.
It said a number of improvements had been made, including removing insulated rail joints, which removes a source of noise, and improving the condition of the tracks.
"The fact that members have voted by a massive majority for action over this matter should alert London Underground to the strength of feeling and act upon in accordingly," RMT general secretary Mick Lynch said.
"If London Underground workers are impacted by these unacceptable noise levels the general public are also being affected by it."
