Guards on ScotRail have voted overwhelmingly to go on strike in a dispute over driver-only trains.
Members of the Rail, Maritime and Transport (RMT) union backed walkouts by 3-1, with a bigger majority for other forms of industrial action.
The union has around 700 members involved in the row. Turnout was 75%.
The result will now be considered by the union’s executive.
A ScotRail spokesman said: “This ballot result confirms that there is very little appetite for strike action in ScotRail. Nearly half of our total number of conductors voted against strike action or abstained.
“This is now a clear signal for the RMT that our people in Scotland want to decide their own way forward. We have already guaranteed job security, pay and the futures of our conductors.
“The RMT must now allow their local representatives in Scotland to consider ScotRail’s ideas that will make these guarantees possible.”
