Metro Tunnel Opening – Timeline Stations and Impacts

Melbourne’s Metro Tunnel officially opened its doors to passengers on November 30, 2025, marking the culmination of nearly a decade of planning and construction for Victoria’s most significant public transport infrastructure project in generations. The underground rail corridor promises to transform how residents move through the city, creating new connections across the metropolitan network.

The opening came after years of construction work that saw massive tunnel-boring machines excavate twin 9-kilometer passages beneath the city centre. The project connects three of Melbourne’s busiest train lines, providing a new dedicated pathway through the central business district that bypasses the aging City Loop underground stations.

Following the opening, authorities implemented a transition period allowing passengers to familiarise themselves with the new route before a major network reconfiguration took effect in February 2026. The project represents a substantial investment in Melbourne’s public transport capacity and forms a cornerstone of the state’s long-term urban mobility strategy.

When is the Metro Tunnel Opening?

The Melbourne Metro Tunnel opened for passenger services on November 30, 2025, with an initial operating phase dubbed the “Summer Start.” This marked the official commencement of revenue service following safety accreditation from the Commonwealth rail regulator.

Key Facts About the Opening

• Passenger services commenced on November 30, 2025, following safety certification from the rail regulator
• Initial operations ran between West Footscray Station on the Sunbury line and Westall Station on the Pakenham and Cranbourne lines
• 240 additional services operated weekly during the opening period, augmenting the existing timetable
• Free weekend public transport was available across all Victoria train, bus, and tram services from opening day until February 1, 2026
• The major network reconfiguration known as the “Big Switch” occurred on February 1, 2026
• Since February 2026, the Sunbury, Cranbourne, and Pakenham lines operate exclusively through the Metro Tunnel
• Passengers initially had the choice between new Metro Tunnel services and existing City Loop services during the transition period

What is the Melbourne Metro Tunnel Project?

The Metro Tunnel is a rail infrastructure project designed to create additional capacity through Melbourne’s central business district. The project involved constructing twin 9-kilometer train tunnels that connect the western and eastern suburbs, providing a new dedicated corridor for three major train lines that previously shared the underground City Loop stations.

The project connects the Sunbury line in the west with the Pakenham and Cranbourne lines in the east, enabling these services to bypass the congested City Loop and travel directly through the city centre. This design separates these lines from other network services, increasing overall system efficiency and reliability.

Infrastructure and Design

The tunnel system runs beneath some of Melbourne’s busiest areas, with underground stations positioned at key locations throughout the CBD and inner suburbs. The infrastructure was built to accommodate high-frequency services, supporting the goal of running more trains more often throughout the network.

Service Integration

The Metro Tunnel integrates three major train lines into a unified corridor, allowing passengers to travel from outer suburban areas directly through the city without transferring. The Sunbury line serves communities in Melbourne’s western suburbs, while the Pakenham and Cranbourne lines connect the southeastern corridor.

The project enables easier connections between different lines and supports the broader goal of encouraging commuters to leave cars at home. Officials have highlighted the potential for enhanced services to western suburbs, particularly through improvements at Sunshine Station.

Which Stations Will the Metro Tunnel Serve?

The Metro Tunnel introduces five new underground stations to Melbourne’s train network. These stations are located at key points throughout the city centre and inner suburbs, providing access to employment, education, retail, and entertainment precincts.

New Underground Stations

Among the stations opened as part of the Metro Tunnel are Town Hall Station and State Library Station. These stations serve the combined Cranbourne, Pakenham, and Sunbury lines, connecting communities across Melbourne’s western and southeastern corridors.

Network Configuration

Following the February 2026 “Big Switch,” all services on the Sunbury, Cranbourne, and Pakenham lines operate exclusively through the Metro Tunnel rather than the City Loop. This arrangement provides consistent service patterns for passengers travelling from outer suburbs to the city centre.

Construction Timeline

The Metro Tunnel project progressed through several key phases over nearly a decade, from initial planning through to passenger service commencement. The following timeline outlines the major milestones in the project’s development.

1. Planning and Funding (2015-2018): Project development and approval phases, including securing federal and state government funding commitments
2. Tunnel Construction (2018-2023): Major civil works including excavation of the twin tunnels using tunnel-boring machines
3. Tunnel Completion (2023): Tunnel-boring operations concluded, with both tunnel passages completed
4. Station Construction (2020-2024): Building of underground stations, track installation, and systems integration
5. Testing and Commissioning (2024-2025): Safety testing, driver training, and regulatory accreditation processes
6. Opening (November 30, 2025): Commencement of passenger services with the Summer Start phase
7. Full Integration (February 1, 2026): The Big Switch transferred all Sunbury, Cranbourne, and Pakenham line services to the Metro Tunnel

Metro Tunnel Opening: What Is Confirmed and What Remains Uncertain

Impact on Melbourne’s Public Transport Network

The Metro Tunnel delivers significant capacity improvements to Melbourne’s rail network. The infrastructure provides the ability to run additional services, particularly during off-peak periods when crowding has historically been less acute.

The project enables more direct routes for passengers travelling from outer suburbs to the city centre. Communities in Melbourne’s western suburbs stand to benefit particularly from the new corridor, with enhanced connectivity supporting both commuters and recreational travellers.

The network redesign supports the objective of encouraging commuters to leave cars at home, offering time and cost savings for those who switch to public transport. The ability to connect different lines more easily creates a more cohesive overall system.

Summary: Melbourne Metro Tunnel Opens for Service

The Melbourne Metro Tunnel officially opened on November 30, 2025, with passenger services commencing after years of construction. The project delivers twin 9-kilometer tunnels connecting the Sunbury, Cranbourne, and Pakenham lines through five new underground stations. Following the “Big Switch” on February 1, 2026, these lines now operate exclusively through the Metro Tunnel rather than the City Loop. The infrastructure supports substantial service increases, including over 1,000 additional weekly services on the Sunbury line, offering passengers improved connections and travel options across Melbourne’s public transport network.
