Coalition Promises $1.7 Billion Hybrid Train Fleet for Melbourne’s West

Commuters in Melbourne’s rapidly growing west could receive Victoria’s first fleet of hybrid diesel-electric suburban trains under a $1.7 billion election commitment announced by the Liberal-National Coalition.

Opposition Leader Jess Wilson said a Coalition government would order 25 new trains for the Melton and Wyndham Vale corridors, which currently rely on diesel V/Line services. The commitment is conditional on the Coalition winning the Victorian state election on Saturday, 28 November 2026.

The opposition says the trains would be manufactured in Victoria and targeted for delivery by 2030. It claims the fleet would more than double passenger capacity on the two corridors, allow additional peak services and potentially enable direct services through Melbourne’s City Loop.

The announcement was made at Cobblebank Station on 1 September, the same day the rebuilt Melton Station opened to passengers.

How would the hybrid trains work?

The proposed trains are described as hybrid diesel-electric, or “bi-mode”, vehicles. They would use electric power where overhead wiring is available and switch to diesel operation on non-electrified sections of track.

That flexibility is central to the Coalition’s argument. Melton and Wyndham Vale sit within metropolitan Melbourne but are still served by regional diesel trains. A bi-mode fleet could theoretically operate on the existing western corridors before full electrification is completed, while also using electrified tracks closer to the city.

Hybrid or bi-mode passenger trains already operate in parts of Europe and comparable technology has been used elsewhere in Australia. However, the exact train design, power system and procurement model have not yet been released.

What is already happening on the Melton line?

The hybrid-train promise is separate from upgrades already funded by the state and federal governments.

The two governments have jointly committed $152.7 million for development work on Melton line electrification. That funding is for investigations, planning approvals, power-supply planning, detailed design, scope and cost estimates. The development work is expected to be completed by mid-2027, but there is still no announced date or fully funded construction program for completing electrification.

A separate $650 million Melton Line Upgrade is preparing the corridor for longer nine-car VLocity trains from 2027. The Victorian Government says those trains will lift peak passenger capacity by 50 per cent. Platforms are being extended at Caroline Springs, Deer Park, Rockbank and Cobblebank, while a new stabling yard at Cobblebank is being designed to accommodate future Metro trains.

The rebuilt Melton Station has four platforms—two intended for future electrified metropolitan services and two for regional services—and longer platforms for the expanded VLocity fleet.

Why the west says it cannot keep waiting

Residents in Melton, Wyndham Vale, Tarneit and surrounding growth areas have repeatedly raised concerns about crowding, service frequency and their reliance on regional trains for suburban journeys.

The Western Rail Plan announced in 2018 proposed separating and electrifying the Melton and Wyndham Vale corridors. Eight years later, neither corridor has a confirmed completion date for electrification.

The Coalition argues that the hybrid fleet would provide “metro-quality” services sooner without preventing full electrification later. It also says replacing 25 VLocity sets in the west would allow those diesel trains to be reassigned to regional corridors, potentially adding capacity elsewhere in Victoria.

Labor and rail experts raise questions

Public Transport Minister Vicki Ward has criticised the proposal, arguing the trains could become redundant once electrification is delivered. She has also disputed the suggestion that diesel-equipped trains could readily operate through the City Loop.

Rail Futures Institute president John Hearsch told the ABC that regulatory approval for trains carrying large quantities of diesel fuel through long underground tunnels could be difficult. He also questioned where extra services would fit on already constrained tracks.

Infrastructure Victoria has continued to identify full electrification as the stronger medium- and long-term solution for Melton. Its chief executive, Jonathan Spear, told the ABC that a broader package—including electrification, track duplication, new stations and trains—had previously been estimated at $4 billion to $5 billion, with an estimated return of about $2 in community benefits for every dollar spent.

What still needs to be clarified?

The Coalition has announced the headline cost, fleet size and 2030 delivery target, but several important details remain unanswered:

How many trains would be allocated to each corridor?

What would be the seating and total passenger capacity of each train?

How many additional peak and off-peak services would operate?

Which tracks and City Loop paths would be available for the services?

What safety and regulatory approvals would be required for tunnel operation?

Would the fleet use diesel alone beyond the wires, or include battery capability?

How would the plan interact with the timetable and funding for full electrification?

What proportion of the $1.7 billion would be funded through new spending or savings elsewhere?

What it means for commuters

For passengers, two different proposals are now in view.

Under the existing government program, longer nine-car VLocity trains are due to begin operating on the Melton line from 2027, increasing peak capacity while electrification planning continues.

Under the Coalition’s election commitment, a new fleet of 25 hybrid trains would be delivered by 2030 for both Melton and Wyndham Vale, provided the Coalition forms government and the plan proceeds through design, procurement and regulatory approval.

The promise places western rail infrastructure firmly at the centre of Victoria’s election campaign. For commuters who have waited years for more frequent suburban-style services, the key question is no longer whether extra capacity is needed, but which plan can be funded and delivered fastest without delaying a permanent electrified network.

Would hybrid trains be a practical solution for the west, or should the government focus only on full electrification? 👇
