A planned strike over the weekend of the London Marathon on Docklands Light Railway has been called off.
Members of the Rail, Maritime and Transport union were due to walk out for four days from 4am on Friday.
The union suspended the action after “significant progress” was made in talks with DLR operators KeolisAmey in a row over outsourcing.
RMT general secretary Mick Cash said: “After 13 days of intensive talks, RMT’s negotiating team has been able to secure significant progress on the key issues of the threat to jobs and conditions from outsourcing and a range of grievances around the principles of workplace justice.
“That progress has been enough to enable our executive to suspend the action and further discussions will now take place moving forwards with the union remaining vigilant as ever and we remain in dispute.”
Mark Davis, interim general manager of the DLR, said: “For the thousands of runners raising millions of pounds for charity this weekend, we are delighted that the planned industrial action on the DLR has been suspended.
“Our services will help all those participating and supporting the London Marathon travel across London for this fantastic event.
“Walking, cycling and public transport will be the easiest way to get around and make the most of the day and I encourage anyone travelling around south east and central London to be aware of the road closures and to plan their journey in advance.”
Abdellah Chajai, managing director of KeolisAmey Docklands, said: “We are pleased to have made progress with the RMT to avert this strike action and prevent unnecessary disruption for our passengers over the London Marathon weekend.
“We will continue to work with the union to ensure we provide our passengers with the best possible travel experience.”
