Residents will know Vic train closures

Residents on Melbourne's outskirts whose train stations will be closed on Code Red bushfire days will know well in advance, Public Transport Minister Jacinta Allan says.

Metro Trains will close the final four stations on the Belgrave line when a Code Red is declared, to protect the safety of its drivers.

No other line will be affected on a Code Red day.

Belgrave is deep in the Dandenong Ranges and one of the most dangerous bushfire areas on the outskirts of Melbourne.

"There is a significant amount of work that goes into informing communities well ahead of the day that the day is likely to be a Code Red," Ms Allan told reporters on Tuesday.

Community workers say the most disadvantaged residents will be most at risk, because they rely on public transport.

Ms Allan said it is important to get as many people as possible out of danger zones early on.

"It just makes common sense to ensure that as few people as possible are in these zones that have been declared Code Red because they are the most dangerous and most extreme days," she said.
