The Pakenham and Cranbourne train lines have been suspended, with bus replacements between Oakleigh and Westall due to a train fault.
Trains will continue to run between Flinders Street and Oakleigh, and between Westall and East Pakenham / Cranbourne, with delays likely.
According to the Public Transport Victoria website, the replacement buses will take over 60 minutes to arrive since the time of the disruption.
These buses will be stopping at Oakleigh, Huntingdale, Clayton and Westall.
The Department of Transport has asked passengers to check station platform displays and for motorists to be more vigilant for extra pedestrians and buses around train stations on the respective lines.
