The Rail, Maritime and Transport union (RMT) says it has suspended all industrial action for Network Rail workers after receiving a new pay offer.
Disruption was expected as rail workers in Scotland were to stage a series of fresh strikes in the long-running dispute over pay, jobs and conditions.
Last month, RMT announced that nationwide walkouts will take place on March 16 in a continued dispute over pay, jobs and conditions and members would then also launch a ban on overtime.
While the dispute does not involve ScotRail staff, the industrial action would have a knock-on effect for services as Network Rail staff occupy critical safety roles.
The industrial action has now been called off after a new pay offer was tabled.
The union said on Tuesday evening: “The RMT National Executive Committee has taken the decision to suspend all industrial action on Network Rail following receipt of a new offer from the employer.
“Further updates will be given on all aspects of the national rail dispute in the coming days.”
