Suburban Rail Loop

Suburban Rail Loop will transform Victoria’s public transport system connecting our suburbs and creating opportunities in great places and $2.2 billion has been provided to kick start the project.

The 90-kilometre Suburban Rail Loop will link every major rail line from the Frankston line to the Werribee line, via the airport, better connecting Victorians to jobs, retail, education, health services and each other.

It will ease congestion and take pressure off the existing transport network and the project will generate a long pipeline of work and construction activity, creating up to 20,000 jobs during construction.

As well as delivering significant transport benefits, Suburban Rail Loop provides an opportunity to plan the services, amenity and infrastructure we're going to need outside of the central business district (CBD) for future generations.

Suburban Rail Loop will be delivered in stages over several decades, with an Initial and Early Works package of works commencing in 2022, (subject  to approvals), paving the way for major construction.

Initial Works and Early Works

The Initial Works and Early Works is expected to comprise a range of preparatory works, including utility relocation and protection works, site establishment works, ground improvement trials, road improvements and underground structures to facilitate the commencement of tunnelling operations. The State intends to conduct a two-stage procurement process and then appoint a Managing Contractor to deliver these works.


Construction of the Initial and Early Works is expected to commence in 2022.

Power Connection Works

The Power Connection Works comprise works required to connect to and supply power from the Victorian electricity system for the construction and operation phases of the Suburban Rail Loop.


Construction of the Power Connection Works is expected to commence in 2022.
