There is significant disruption to trains across the Forth Valley this week.
No services will run from Stirling or Falkirk to Edinburgh from today until Friday.
Network Rail teams are carrying out "urgent" work to prevent rockfall on the line near Ratho.
Services from Dunblane to Edinburgh will end at Falkirk Grahamston.
The operator says "limited" replacement buses will be running.
Phil Campbell, ScotRail customer operations director, said: “Due to these engineering works, there will be significant disruption to the services ScotRail can operate between Edinburgh and Glasgow, Bathgate, Linlithgow, Stirling, and Inverness.
“We understand the disruption this will cause to customers' journeys, but it is essential that Network Rail carries out these works.
“ScotRail’s advice to customers travelling between Edinburgh and Glasgow via Falkirk High or via Bathgate, and between Edinburgh and Dunblane, is that you should only travel if your journey is essential.
