Passengers have been warned of further significant disruption across train services in Scotland due to continued strike action from railway staff.
Network Rail's RMT members will take part in a 24-hour strike on Saturday across the UK railway network amid an ongoing dispute over pay and conditions.
The action will impact services north of the border as many staff members walking out occupy safety-critical roles and, as such, ScotRail said the "vast majority" of trains will not run on the day.
