The threat of national rail strikes has been lifted following talks over a pay deal, according to the arbitration service Acas.
A 24-hour strike by Network Rail staff members of the RMT union was to have taken place from 5pm on Thursday, followed by a 48-hour walk-out next week.
Acas said four days of talks helped “formulate” revised proposals for the RMT and other unions to consider.
The RMT has 16,000 members at Network Rail in operations and maintenance.
RMT general secretary Mick Cash said the union would consult on the details of the revised package.
Members of the TSSA and Unite unions will also be consulted.
Network Rail chief executive Mark Carne said: “I am very pleased that the industrial action has been suspended. With Acas’s help, we have had very constructive talks with the unions over the weekend and I hope they will be able to agree this deal.”
A planned strike starting on the May 25 bank holiday was suspended by the RMT and TSSA after Network Rail tabled a revised pay offer to workers. The offer was not accepted by RMT members.
South West Trains, which runs commuter services into London, said: “The suspension of industrial action means that South West Trains will run normal weekday services on Thursday and Friday and the following week from Tuesday until Thursday, June 11.”
