The Rail, Maritime and Transport (RMT) union today (30 May) announced two-day strikes from June 15 and 29.  

The walkouts will involve maintenance staff at ScotRail’s “outbase” in Perth, where trains are refuelled and stored overnight.  

News of the latest stoppages comes days after the union warned of a “long summer of strike action” over a separate dispute about train conductors and ticket examiners being paid less than drivers for working on days off.  

It has led to most ScotRail trains being canceled on Sundays since last month, with the RMT saying that could continue until September.  

RMT Scotland organiser Mick Hogg predicted the impact of those stoppages would be “massive”, which was denied by ScotRail .  

He said: “No trains would be able to get in or out of Perth as no personnel will be in attendance.
