Train services from Falkirk Grahamston to Glasgow Queen Street will be restored on Saturday.
The route was disrupted when trains were cancelled between Grahamston and Cumbernauld following the closure of the Forth Road Bridge.
Scotrail pulled train carriages from routes which had other transport links – Falkirk High in the town’s case – to use them to cope with the extra demand on other lines in Fife and the Lothians as more commuters shifted to the trains when vehicle access was closed across the bridge.
The vital road link opened again last Wednesday, but Scotrail said it takes time to get services back to normal.
A spokesperson said: “Unfortunately, returning services to normal is not an overnight fix.
“A lot of factors, such as train diagrams and platform arrangements make this a complicated exercise.
“We would like to thank our customers for the incredible patience they have shown over the closure of the Forth Road Bridge.”
