Buses are replacing trains on the Belgrave line between Bayswater and Upper Ferntree Gully, due to fallen trees on the tracks.
Some services may terminate at Ringwood and be met by replacement buses there. Passengers should listen for announcements, check platform displays and allow extra travel time.
The Department of Transport and Planning signals team is monitoring conditions in the area and will adjust traffic lights to assist with bus movements.
Real-time traffic conditions are available at traffic.vicroads.vic.gov.au.
