Train services in the north and north-east will be completely cancelled at the start of next week should the planned industrial action of rail workers go ahead.
Thousands of Network Rail employees are anticipated to strike for 24 hours from 5pm on Monday due to a row over pay.
Members of the Rail, Maritime and Transport (RMT) union and the Transport Salaried Staffs Association (TSSA) have rejected a four-year pay deal of £500 followed by three years of rises in line with RPI inflation.
Scottish Transport Minister, Derek Mackay said the Scottish Government was “working hard to try to mitigate that impact”.
However he warned that if the strike goes ahead, it will have a significant impact on the roads and rail services while ScotRail confirmed it will only be able to run a handful of routes.
The only routes to run on Monday, with limited services, will be Glasgow Central-Paisley Gilmour Street; Glasgow Central-Newton via Maxwell Park; Glasgow Central-Neilston via Queens Park.
And on Monday and Tuesday, only the following services will be running, with restricted timetables: Edinburgh-Glasgow via Falkirk High; Edinburgh-Kirkcaldy-Glenrothes; Edinburgh-Cowdenbeath-Glenrothes; Glasgow Central-East Kilbride; Glasgow Queen St (High Level)- Anniesland; Glasgow Queen St (High Level)-Cumbernauld.
ScotRail Alliance managing director Phil Verster said the firm was “very disappointed” to have to be making such a large number of cancellations.
He added: As it is a UK wide national strike “there’s very little we can do about it from the Scotland side.
“What’s most important for us is to help our customers make decisions about Monday and Tuesday.
“Alternative travel is obviously a very high priority, and working from home, those type of options are unfortunately where we are.”
“Around 470 signallers are expected to take part in the strike and their role is a “very specialised skill and in order to run the railway safely we need those people in place”.
“There is only 23 contingency signallers who could “step in for the 470 people that go on strike, so our capability to step in is very, very limited.”
RMT general secretary Mick Cash said: “RMT is continuing to push for a negotiated settlement through the Acas talks and the union is available right the way through the weekend to keep that process going, if necessary.
“In the meantime, our picketing arrangements are in place and the response coming back from our members is one of rock-solid support.
“We would remind the public that we have been forced into this dispute through a wholly-unwarranted attack on safety-critical jobs, pay and working conditions that would seriously undermine the safety of passengers on our railways into the future.
“RMT members are standing up for the principle of a properly staffed and resourced railway where safety comes first and where corners aren’t cut to hit budget targets.”
