Trains across the UK have come to a halt as 40,000 members of the Rail, Maritime and Transport union (RMT) have walked out.
This comes after months of discussions following a dispute over pay, working conditions and job security. Thursday's strike action marks the first out of two strike days planned.
The majority of trains across Scotland have been cancelled with only a small amount of services running to and from Glasgow today (Thursday). Staff from Network Rail and 14 train operators are taking part in the industrial and although ScotRail staff are not associated, the action is having a significant knock-on-effect.
