Scotrail passengers are facing a series of six strikes over the next few weeks in a dispute over the use of driver-only trains.
Guards working for the Scottish rail franchise, which is operated by Abellio, have voted to take industrial action in a ballot held by the RMT union.
The first strike is due to take place for 24 hours next Tuesday, June 21, followed by 48-hour walkout on June 25-26, and then further 24-hour stoppages on July 3, 10 and 17.
RMT general secretary Mick Cash said: “It is extraordinary that Abellio/Scotrail continue to ignore the strength of feeling amongst their staff over the extension of DOO (driver only operation).
“Our members on Scotrail stand determined and united in this fight for jobs and safety on Scotland’s rail services.”
Scotrail said that the solution to the dispute “lies in talks not strikes” and added that negotiations with the RMT would continue today (June 15).
In a separate dispute, conductors working on Southern trains are set to hold another 24-hour strike on June 21 in a long-running battle over plans by franchise operator Govia Thameslink to change the role of conductors from August 21.
Southern, which operates trains between London and the South Coast, has also been affected in recent weeks by a high level of sickness among conductor leading to delays and cancellations to services.
