Ballarat train commuters will gain access to an extra weekday peak period service from April next year.
The extra service will run during both peak periods.
The announcement came from Public Transport Minister Terry Mulder on Thursday and was expected to be one of the major outcomes from the completion of the Regional Rail Link project.
"The extra morning and afternoon peak period trains will add hundreds of seats for Ballarat's growing number of peak period travellers," Mr Mulder said.
"Passengers are already benefiting from the newly built Sunshine and Footscray stations.
"V/Line trains now travel between Sunshine and Southern Cross free of Metro's suburban trains thanks to the two new dedicated Regional Rail Link tracks."
Ballarat train commuters have previously expressed frustration at the delays caused by Metro trains which impact on the V/Line services.
While RRL is expected cut down on these delays an announcement earlier this year to build another passing loop is seen as a possible solution to the growing number of delays which occur between Ballarat and Sunshine.
The RRL project is currently under budget and ahead of schedule with the Ballarat portion of the project basically complete.
