The Liberals promised $1.7 billion for electric trains that also run on diesel. Two weeks ago they scrapped the power line.

One Nation is polling 23 per cent in Victoria and wants renewable energy zones abolished. The Coalition has stopped saying net zero.

The Liberals will spend $1.7 billion on trains that carry their own diesel engine.

Opposition Leader Jess Wilson announced 25 hybrid electric trains for the Melton and Wyndham Vale lines on Wednesday, running on overhead wires where they exist and diesel where they do not.

Both lines were supposed to be electrified by now.

Labor promised it in 2018 under the Western Rail Plan and again before the 2022 election, and has since put $152.7 million into planning the Melton conversion with the Commonwealth.

There is still no completion date for either corridor.

Almost twelve years in, Melbourne's outer west runs on regional diesel.

The Coalition's answer is not to build the wires.

It is to buy trains that do not need them.

Freeing the 25 three-car V/Line sets sends five extra V'Locity sets each to Gippsland, the north east, northern Victoria and the south west, four to the west, and one to reserve.

That is 5,328 seats redistributed across the regional network.

Shadow public transport minister Matthew Guy said regional Victorians should not miss out because "Labor has failed to properly plan for a growing state".

Two weeks ago the Coalition promised to scrap VNI West, the $7.6 billion interconnector built to move renewable power between Victoria and New South Wales.

It would unlock conventional gas, unwind Labor's restrictions on gas in new buildings and let coal run to the end of its life.

Shadow energy minister David Davis called it hard-nosed economic pragmatism and denied the shift had anything to do with One Nation.

On Monday Pauline Hanson stood in front of Loy Yang A with One Nation's Victorian leader Warren Pickering and promised to scrap net zero subsidies, abolish renewable energy zones, repeal the state's nuclear ban and keep the plant burning past its 2035 closure.

The party provided no costings.

Loy Yang A supplies about 30 per cent of Victoria's electricity.

One Nation is polling 23 per cent in Victoria.

The Coalition is on 27.

When the federal Liberals dumped net zero last November, Ms Wilson refused to say whether Victoria's 2045 target would survive.

Her predecessor Brad Battin had said a week earlier that he was comfortable keeping it.

Energy Minister Jaclyn Symes now calls the opposition "Jess Wilson's One Nation-Coalition".

Renewables made up 45.1 per cent of Victoria's generation last financial year.

A hybrid train is a reasonable piece of engineering.

It is also an exact description of the politics: electric where somebody has already built the wires, diesel everywhere else, and no promise to build any more.
