People across the Forth Valley are being warned to expect disruption, as train staff strike.
There are no trains to Stirling or Alloa until Sunday, as members of the RMT union walk out in a dispute over pay.
One service an hour will run from Glasgow Queen Street and Edinburgh Waverley to Larbert.
One hourly train also operates from Glasgow to Falkirk Grahamston.
However, the final services will leave before 6:30pm each evening.
David Simpson, ScotRail Service Delivery Director, said:
“It’s really disappointing to see more widespread disruption across the whole Great Britain rail network as a result of the dispute between Network Rail and the RMT at a time when we need to be encouraging more people back to the railway.
“For ScotRail, it’s going to mean that we won’t be able to operate the vast majority of our services between 3 and 7 January, which we know will be really frustrating for our customers.
“We’re advising customers to seek alternative means of transport and to only travel if they really need to on the days of strike action.
“Customers should check their journey in advance to make sure your train is running.”
