The South Morang train line is getting 115 new and extended week day services.
Thomastown MP Bronwyn Halfpenny said the services would include 45 extra peak trains and 70 day and evening services each week.
Ms Halfpenny also said 982 services would be extended from South Morang to the new Mernda station when the Mernda extension opens later this year.
The first test trains are set to begin running on the line in September.
The announcment follows a construction blitz in the past few months aimed at getting trains running on the extension as soon as possible.
A spokesman from the South Morang and Mernda Rail Alliance, Darren Peters said the addition of extra peak hour services was “fantastic” but there was still work to do to make the city commute easier.
“An issue that still needs to be addressed is parking, as 500 extra cars from South Morang’s temporary carpark will be dumped on surrounding stations after the state election,”
Mr Peters said.
“Both parties need to maintain or expand the parking capacity at South Morang, not reduce it, and this could be solved by building a multi-storey carpark over the existing one.”
