Warrnambool train line passengers have been advised to expect delays on Wednesday with the 9.25 am service cancelled and replaced by road coaches for the entire journey.
Services have been held or stopped from arriving and departing Southern Cross station following an equipment fault in the Sunshine area.
Waurn Ponds to Melbourne services have also been cancelled. Customers from Waurn Ponds and Marshall have been advised to board a replacement coach to South Geelong and board the next departing train service to complete their journey.
The equipment fault was repaired about 8am but customers have been advised to expect delays up to 20 minutes.
Performance on the Warrnambool train line has increased five per cent from the month before.
V/Line's monthly performance figures revealed 79.6 per cent of trains were delivered on-time in February.
It's been 11 months since the transport service hit its punctuality target of 92 per cent.
Temporary speed restrictions between Colac and Warrnambool were lifted last week following the completion of a $118 million sleeper replacement project.
Major maintenance works will continue next month, with buses replacing trains for the entire journey between April 6 and 21.
Those works include the replacement of two bridges at Allansford and Warrnambool's Otway Street bridge.
