LOUD mobile phone conversations and tinny noise from earphones may soon be a thing of the past for commuters on V-Line trains.

Passengers boarding the 10.08 to Ballarat from Southern Cross Station this morning will have the option of jumping in the last carriage of the three-carriage train for a journey free of the beeping noises and raised voices.

The six-month trial is being conducted on the new Velocity trains to and from the commuter belts of Geelong, Ballarat, Bendigo, Seymour and Traralgon.

The idea of toning down noisy distractions for commuters is not new.

Japanese train travellers, along with Brisbane and NSW Central Coast commuters, already have that privilege.

Now it's Victoria's turn and, while it won't be strictly enforced, if you get on a quiet carriage on V/Line you will be expected to switch mobile phones to silent and turn down electronic devices.

Victorian Public Transport Minister Terry Mulder said the quiet carriage is a welcome innovation.

"V/Line has listened to its customers and taken action to give this idea a try," Mr Mulder said.

"This is about creating some space that encourages fellow passengers to further respect each other's journey."

V/Line Acting Chief Executive Ross Pedley said quiet carriages have been successfully adopted in Queensland.

"By mid-year we'll know if our customers embrace the concept," Mr Pedley said.

"Most of us are guilty of having loud conversations or listening to music on the train and that's perfectly fine.

"But with increasingly hectic lives, there is a growing demand from people who seek some peace and quiet."

Mr Pedley said there won't be any penalties for breaking the rules but V/Line expects common courtesy from all its passengers.

He said it won't be possible to schedule the same train on the same service every day, so regular customers may not always have a quiet carriage for their journey during the trial.
