A major power outage in Melbourne’s north caused significant delays for commuters on Monday night.
More than 30,000 properties in the Darebin and Moreland areas were affected by the outage, according to the CitiPower website.
The website listed the cause of the outage as "under investigation", while the time power was estimated to be restored was pushed from 9pm to 12.30am.
Significantly affected suburbs included Brunswick, Northcote and Thornbury.
A Metro spokeswoman said the power outage had heavily affected the South Morang service line, with a number of stations losing signalling power and station lighting.
Buses were replaced trains between Clifton Hill and Bell stations and delays of up to 30 minutes were experienced for commuters on the Upfield line.
A VicRoads spokesman said about 30 to 40 traffic lights had lost power in the region.
