RMT strike will cause significant disruption to Scotland's train network, according to ScotRail.
Due to industrial action, ScotRail has issued a warning about substantial disruption this week on Scotland's rail network, emphasizing that people should only travel if it is absolutely necessary.
Workers at Network Rail who are members of the RMT union have said they will strike this week on Thursday and Saturday due to a salary disagreement.
Even while ScotRail, the publicly owned rail company north of the border, is not a party to the dispute, the RMT's proposed action will affect Network Rail employees in Scotland, which will have a significant negative impact on ScotRail's ability to run services.
Since signallers will be among those on strike, the majority of services will be canceled.
A previous union strike only permitted 189 routes to run, but this round will see 378 trips run due to trains expected to arrive in Fife and along the east coast.
Edinburgh and Glasgow Queen Street, Edinburgh and Helensburgh Central, Glasgow Central and Hamilton, Glasgow Central and Lanark, Edinburgh and Inverkeithing, Edinburgh and Tweedbank, and Milngavie and Springburn will all have two trains per hour service.
Between Edinburgh and Glasgow Central, Edinburgh and North Berwick, Glasgow Queen Street and Larbert, and Glasgow Queen Street and Falkirk Grahamston, there will be one train per hour on the days that are affected.
The last train will depart "far before" 6.30 p.m., according to the operator, and the services will run from 7.30 a.m.
David Simpson, the operator's service delivery director, said, "It is very regrettable to see such broad disruption throughout the entire Great Britain rail network and we know this will be frustrating for ScotRail customers."
"Unfortunately, we will be unable to run the great majority of our services throughout the strike action period due to the strike by RMT members of Network Rail.
"On strike days and the next day, customers may expect major service interruptions.
"We are able to operate on more routes than the day before the strike, but we are still only able to run a very limited number of services on these routes, so we're encouraging clients to seek out alternate forms of transportation and to only travel if they really need to."
With signal boxes in the central belt able to be turned on at roughly 7.15am, ScotRail warned disruption is also expected to be noticed the day after the strikes. However, it may take until the afternoon to restore services in other regions.
