Buses are replacing trains on the Sunbury Line between Sunshine and Watergardens, due to an emergency services incident.
Trains will continue to run between Flinders Street and Sunshine, with delays to the service.
V/Line trains on the Bendigo Line are also disrupted with trains terminating/originating at Sunbury.
This incident will likely impact the start of the afternoon peak. Passengers are asked to check station platform displays, listen for announcements, and allow extra time for their journey.
Motorists are asked to be vigilant for extra pedestrians and buses around train stations on the Sunbury Line.
The VicRoads signals team is monitoring conditions in the area and will adjust traffic lights to assist with bus movements.
