A five-day strike by train drivers at LNER next month on top of a rolling programme of national walkouts has been called off, sources said.
Members of Aslef are launching a series of strikes and an overtime ban from January 29 in the long-running dispute over pay,
The union announced a further five days of strikes against LNER from February 5 amid speculation that the company was considering implementing the new minimum service level regulations.
It is understood this will not happen during the upcoming strikes which has led to the five days of action being withdrawn.
Aslef has been approached for comment.
The new law is aimed at ensuring a minimum level of service is available during strikes, set at 40% in the railway industry.
Unions have warned the regulations are unworkable and potentially dangerous if passengers believe a certain number of trains will run.
None of the train companies affected by the new strikes have said they will implement the regulations.
Unions in other sectors affected by the new law have also warned they are unwarranted and unworkable.
An LNER spokesman said: “We welcome news that the threat of extended disruption to our services has been lifted.
“We encourage Aslef to work with us to find a way to end this long-running dispute, which only damages the rail industry.”
