Project Scope

The Suburban Rail Loop (SRL) proposed by the Victorian Government would see a circa 90 kilometre rail loop of the Melbourne metropolitan area, connecting to every major rail line from the Frankston Line to the Werribee Line via Melbourne Airport.

In September 2019, the Victorian Government established the Suburban Rail Loop Authority (SLRA) to manage and lead development on the project.

The Loop will consists of four sections:

  • South-East - Cheltenham to Box Hill 
  • North-East - Box hill to Melbourne Airport
  • North-West - Melbourne Airport to Sunshine (part of Melbourne Airport Rail Link (MARL)), and
  • South-West - Sunshine to Werribee line.


The precincts to be connected by SRL include: Cheltenham, Clayton, Monash, Glen Waverley, Burwood, Box Hill, Doncaster, Heidelberg, Bundoora, Reservoir, Fawkner, Broadmeadows, Melbourne Airport, Sunshine and Werribee.

As well as providing a rail link to the airport, the project will also build three 'transport super hubs' at Clayton, Broadmeadows and Sunshine to connect regional passengers to the Suburban Rail Loop.

Given the scale of the Loop, construction is to be staged over several decades, with the south-east and north-west sections to be constructed first. The north-west section will be constructed as part of the Melbourne Airport Rail Link (MARL).

The south-east and north-east sections have a preliminary costing in the range of $30-$50 billion. The north-west has been costed at $8-$13 billion as part of MARL. South-west has not been costed but will be constructed in sections over a period of decades. The SRL is expected to use a mix of above and below ground rail across the four sections.

Exact station locations, route alignment, rolling stock and staging will be confirmed through the business case process. A strategic assessment of the Loop has been conducted by Development Victoria in conjunction with Rail Projects Victoria (RPV).

The 2019-20 Victorian Budget committed $300 million towards commencing detailed planning and pre-construction works for the project.

In June 2019, Registrations of Interest were called for enabling the Government to assess market capacity to deliver the project. The ROI process is not a pre-qualification for any formal procurement process.

In November 2019, the Victorian Government announced the SRL will be serviced by a new fleet of trains that will be four to five carriages long and be capable of travelling at higher speeds than the existing fleet. The shorter train design will also result in shorter station platforms.

Q3 2020: Business case to be finalised

Q4 2020: Estimated start of procurement

Q3 2022: Estimated end of procurement

Q4 2022: Estimated start of construction



The south-east section from Cheltenham to Box Hill is stage one of SRL. It is proposed to include new interchanges with the Frankston, Cranbourne-Pakenham, Glen Waverley and Belgrave-Lilydale Lines.

The Victorian Government indicated in the lead up to the 2018 State election, that business case development, detailed design and community consultation would commence in 2019 to allow procurement to commence in 2020 and initial works to begin in 2022. 

In May 2019, the Victorian Government announced Rail Projects Victoria (RPV) had engaged the Aurecon Jacobs Mott MacDonald Joint Venture (AJM) as technical adviser and KPMG as commercial adviser for the project.

In July 2019, geotechnical investigations began at a range of locations between Box Hill and Cheltenham. 

In September 2019 the Victorian Government announced that responsibility for the delivery of the project would transfer from RPV to SRLA, and confirmed the route for stage one. The South East section will comprise of stations at Cheltenham, Clayton, Monash, Glen Waverly, Burwood and Box Hill. Consultation is being undertaken to determine options for the locations of stations in these precincts.

The section will be constructed underground via twin tunnels.

According to the Victorian Government, State and Commonwealth government funding along with private sector contributions and value capture will be required to fund the project.

The Victorian Government has indicated the first stages - South East and MARL - will take up to 10 years to construct.
