London Underground: RMT drivers in safety row action
London Underground (LU) drivers will refuse to follow new instructions after voting for industrial action in a row over safety, a union has said.
The Rail Maritime and Transport union (RMT) said its members would instead continue to use "proven" safety procedures on the Tube.
London Underground (LU) said it hoped the majority of drivers would apply the new process, which reduces workload.
It said there would be no impact on the service customers receive.
Last week RMT members voted in favour of industrial action, listing a series of concerns including a new procedure for reversing a train.
The union is also in dispute over drivers being "forced" to self-dispatch trains, which the RMT said was being introduced because of cuts in station staff.
RMT general secretary Bob Crow said: "London Underground is attempting to impose dangerous operational changes that are cost-led, will undermine established safety procedures and will put our members and the travelling public in potential danger."
But LU said the fact that 70% of those balloted rejected the union's call for action short of a strike or did not vote at all showed the RMT leadership was out of step with its members.
Howard Collins, LU's chief operating officer, said: "We hope the vast majority of drivers will simply apply the new process, as they already are doing, as it reduces workload and disruption to them as well as being of benefit to our customers.
"In any event there will be no impact on the level of service we deliver to customers."
