The proposed rail strike on Monday, May 25 and Tuesday, May 26 has been called off.
Members of two trade unions employed by Network Rail had announced industrial action to take place over those two days.
But this afternoon the Transport Salaried Staffs Association and the Rail, Maritime and Transport union (RMT), put those plans on hold after they received a new offer from Network Rail.
Virgin Trains East Coast had planned to offer a truncated timetable for the duration of the strike.
Officials from both unions have spent the last four days in talks with Network Rail at the conciliation service Acas.
Manuel Cortes, general secretary of the TSSA, said: “Our negotiating team at Acas has received a revised offer from Network Rail. “As a result of this, they have suspended the planned industrial action, pending the outcome of a meeting of our workplace representatives next week.”
