The public is being warned to expect more disruption on the railway next week as the latest round of strike action by RMT members gets underway.
Network Rail workers will take strike action on Tuesday 13, Wednesday 14, Friday 16, and Saturday 17. A vote on a pay offer is due to close on Monday but even if the action is called off, it would take at least 48 hours to restore normal service.
ScotRail customers have been told to expect a limited number of services operating on a reduced number of routes.
