About Inland Rail

Inland Rail is a fast freight backbone stretching more than 1,700km that will transform how we move goods around Australia by providing transit times of less than 24 hours between Melbourne and Brisbane.

It will better link regional businesses, manufacturers and producers to national and global markets and generate new opportunities for existing and emerging industries.

Comprising 13 individual projects, Inland Rail is the largest freight rail infrastructure project in Australia and will enable safer, less congested highways, fewer carbon emissions, cheaper freight costs and new economic opportunities for our regions.            

Inland Rail is a shot in the arm for Australia’s economy, generating $18b in economic benefits and over 21,000 direct and indirect jobs.

The Australian Government selected the Australian Rail Track Corporation (ARTC) to deliver Inland Rail, in partnership with the private sector.

Gowrie to Kagaru Public Private Partnership (PPP)

In 2017, the Australian Government confirmed the Gowrie to Kagaru section of Inland Rail in Queensland will be designed, built, managed and financed through a PPP.

The 128km Gowrie to Kagaru section is the most technically complex of the 13 projects comprising Inland Rail. It requires the construction of a 6.2km tunnel through the Toowoomba Range, numerous viaducts, bridges and crossing loops to build a new dual gauge track traversing Toowoomba, the Lockyer Valley, Ipswich and the Scenic Rim.

The Gowrie to Kagaru section is divided into three separate projects:

Gowrie to Helidon

The 28km Gowrie to Helidon section includes constructing a new track through the Toowoomba and Lockyer Valley region in Queensland and building a vast freight tunnel.

The new dual gauge track will run from Gowrie, north-west of Toowoomba to Helidon, east of Toowoomba. It will include several significant viaducts and cuttings designed to create an efficient route through the steep terrain.

A new 6.2km tunnel will be built through the Toowoomba Range, making it the largest diameter diesel freight tunnel in the southern hemisphere.

Helidon to Calvert

This 47km stretch of Inland Rail involves the construction of a new dual gauge rail line connecting Helidon (east of Toowoomba) with Calvert (west of Ipswich), in Queensland.

The project crosses the Lockyer Valley and Ipswich local government areas, travelling through Placid Hills, Gatton, Forest Hill, Laidley and Grandchester. Work will include building an 850m-long tunnel through the Little Liverpool Range, near Laidley.

For more information on the Helidon to Calvert project visit

Calvert to Kagaru

The 53km Calvert to Kagaru section of Inland Rail includes building a new dual gauge track to provide convenient access for freight to major distribution centres at Bromelton and Acacia Ridge in Queensland.

The route will divert from the West Moreton rail line near Calvert and connect to the existing Sydney to Brisbane interstate rail line at Kagaru. In addition to the new track, the works are expected to include a 1.1km tunnel through the Teviot Range, 27 new bridges and up to four crossing loops.

The Narrabri to North Star (N2NS) section comprises an upgrade to approximately 186km of track within the existing rail corridor and construction    of approximately 2.3km of new rail corridor. The works are required to accommodate the operation of 1,800m-long double-stacked freight trains      and will involve the modification of various structures

View Project

Inland Rail is transforming how everyday goods are moved around our vast country. It will complete the backbone of the national freight network by providing transit times of less than 24 hours for freight trains between Melbourne and Brisbane via regional Victoria, New South Wales and Queensland.

View Project

The Tottenham to Albury section of Inland Rail will upgrade 305km of existing rail corridor between metropolitan Melbourne and the Victoria-NSW border at Albury-Wodonga.

Due to its scale and complexity, this project is broken into two stages:

  • Stage One: Beveridge to Albury
  • Stage Two: Metropolitan Melbourne
View Project

The Rail Corridor Program involves the delivery of above-ground works, which includes track construction, rail welding, transportation of materials, and the installation and commissioning of level crossings on approximately 570 kilometres of railway between Narromine and Moree in New South Wales and North Start (New South Wales) to Gowrie in Queensland taking in the project's largest greenfield sections.

View Project

The Central Civil Works Program will focus on an 85km (approximately) section between North Star in New South Wales and Whetstone in Queensland as well as a separate 14km package south of Moree called Narrabri to North Star Phase 2.

The Works are allowing for future connections to Goondiwindi and the broader region. It follows the existing track north from North Star before crossing Bruxner Way and the border to join the existing Queensland Rail line.

View Project

The Northern Civil Works Program comprises approximately 138km of new dual gauge track and approximately 69km of upgraded track and crosses the local government areas of Goondiwindi and Toowoomba.

The Northern Civil Works section of Inland Rail will connect one of Australia’s most productive farming regions to markets across the country.

Once complete, Inland Rail will help producers be more competitive, connecting them to markets in Brisbane, Melbourne, Sydney, Adelaide and Perth more efficiently, more reliably and in larger volumes.

View Project

The Albury to Parkes section involves extensive enhancements to specific sites across the 355 kilometres of existing track running from Albury to Illabo and Stockinbingal to Parkes. 
The enhancements would provide the necessary vertical and horizontal clearance along the existing ‘Main South Line’ corridor to support the safe running of double-stacked freight trains up to 1,800 metres long and 6.5 metres high.

The Albury to Parkes section is divided into two separate projects Albury to Illabo & Stockinbingal to Parkes.

View Project

The Southern Civil Works Program involves construction of 306km of new single track rail line from Narromine to Narrabri. It is the longest project within Inland Rail.

This 306km of new track is a crucial part of delivering our fast and reliable freight rail service between Melbourne and Brisbane.
