Buses will replace trains at Helensburgh Central station next weekend.
ScotRail has confirmed that train services will be swapped with buses on Saturday, November 9 and Sunday, November 10 between Helensburgh Central and Dumbarton Central.
This is due to engineering works taking place between the two stations, closing all lines.
Travellers planning on using rail services during the weekend are being urged to plan ahead.
People are also advised that replacement vehicles may be busier than usual, and should allow extra time for journeys.
