RMT has announced further national strike action across the Great Britain railway network in a separate dispute with Network Rail and other train operating companies.
This means Network Rail members of the RMT will be striking on 27 July, and 18 and 20 August.
While this is a separate dispute, the planned strikes on those three days will cause disruption to ScotRail services, as Network Rail Scotland signallers and maintenance staff, who are in safety-critical roles, will be on strike.
No Trains will operate across Ayrshire on the above strike days. The following services will also be cancelled on Thursday 28th
