Planned strikes by workers on Avanti West Coast have been suspended.
Members of the Rail, Maritime and Transport union (RMT) were due to walk out on December 22, 23 and 29.
The union members, who work as train managers, will now vote on a revised offer aimed at resolving a row over rest day working.
An Avanti West Coast spokesperson said: “We are pleased that the RMT have decided to suspend these strikes which would have caused major disruption to our services and this will come as a relief to our customers who were making travel plans over the Christmas period.
“We remain open to discussion with the RMT and await the outcome of the referendum where train managers can vote on this offer.”
