Trains have resumed on the Werribee line between Laverton and Werribee stations following an earlier track equipment fault.
Buses will continue to supplement trains as the timetable is restored.
Passengers are asked to allow extra time for their journey as trains get back into position during this time.
The Department of Transport has thanked passengers for their patience as crews worked to resolve the issue.
Real-time traffic conditions are available at traffic.vicroads.vic.gov.au or via the VicTraffic mobile app. The latest public transport information and network status is available at ptv.vic.gov.au or in the PTV mobile app.
