No trains will run from Stirling, Alloa or Falkirk Grahamston during strike action today.
Members of the RMT union are also walking out on Thursday and Saturday.
It's in a dispute over pay.
The only local service will be two trains an hour on the Edinburgh to Glasgow route via Falkirk High.
The service will end at 6:30pm, though - with no trains at all north of the central belt.
