Nicola Sturgeon has called on the UK Government to "intervene immediately" to avert a rail strike over the festive period.
The First Minister and the general secretary of the Scottish Trades Union Congress (STUC) Roz Foyer want all parties to get around the table to end the pay and conditions dispute.
Members of the Rail, Maritime and Transport Workers union (RMT) are set to take strike action from 6pm on Christmas Eve until 7am on December 27 and again on January 3 and 4, and then on January 6 and 7.
