Train passengers have been warned to expect significant disruption this week as rail workers take further strike action in a dispute over pay, jobs and conditions.
The RMT union has announced its members at Network Rail will take strike action on January 3, 4, 6 and 7.
The dispute does not involve ScotRail staff but will have a major impact on the train operator’s ability to provide services as many of the Network Rail workers walking out occupy safety-critical roles.
