Public Transport Victoria will consider public opinion when naming five new train stations being built under the Metro project.

The stations currently have the working titles Arden, Parkville, CBD North, CBD South, and Domain.

What should the new stations be named? Comment below.

Prominent Victorians have already started playing the name-game.

Melbourne University vice-chancellor Professor Glyn Davis has suggested Parkville station be named University.

"The presence of a University station- literally speaking, on Grattan St and as represented on the Metro rail map - would contribute significantly to Melbourne's identity, tourism and civic pride as a city of education, innovation and knowledge," Professor Davis said.

Lord Mayor Robert Doyle, a Geelong footy fan, has also chimed in, suggesting CBD North and CBD South stations be named after Cats players Joel Selwood and Patrick Dangerfield.

"Part of me says Selwood for CBD North and Dangerfield for CBD South, but in reality perhaps Latrobe and Hoddle would be more appropriate," he said.

"I'm sure there'll be many more suggestions. I like the idea of Melbourne Central station being called Library, or the idea of University for the Parkville station... I think there'll be great debate, but I think we can do better than the names so far."

PTV said any name suggestions would need to be within state government naming guidelines.

The stations will form of Melbourne's $10.9 billion dollar cross-city rail tunnel.
