Wednesday’s announcement that the state government is considering a 4G upgrade to services on Melbourne’s metro train network has sparked outrage locally, with commuters still waiting for a time frame for works on a commitment to improve reception between Ballarat and Melbourne.

The $18 million RRCP was originally budgeted as a free Wi-Fi service for V/Line trains under the former Liberal government but scrapped in favour of a plan to address black spots along regional lines, including Ballarat.

The Ballarat line is plagued with black spots, mostly between Warrenheip and Melton.

A spokesperson for Small Business, Inovation and Trade Minister Philip Dalidakis did not say when construction would start, how many towers would be built along the Ballarat line or where they would be located.

By contrast, Wednesday’s announcement revealed the 4G upgrade could take just six months.

It’s understood an announcement on the RRCP will be made in coming weeks, while the spokesperson said “multiple carriers” will be involved. Telstra, Optus and Vodafone are vying for the contract.

Western Victoria MP Joshua Morris said the lack of movement on the project has failed regional commuters.

“It’s been two years since the election and Ballarat commuters are still waiting for the government to make a decision about improving mobile connectivity on V/Line,” he said.

“Today’s announcement shows that the under an Andrews government, regional Victoria plays second fiddle to Melbourne.”

Committee for Ballarat chair Janet Dore said the focus on 4G was “obviously” a priority over Ballarat.

“Never mind about Wi-Fi, we want a basic, continuous service,” she said.

“We'd be very disappointed if something isn't done soon – it's not good enough.”

The project is well behind schedule, with construction originally planned for mid-2016.
