Works and planning

The final proposed rail alignment for the Narromine to Narrabri section builds on 15 years of engineering and environmental investigations by some of Australia’s most trusted consultants, robust community engagement and constant design refinements.

With primary regulatory approvals now in place, Inland Rail will commence preparation of the environmental and social management plans, permits and licenses, which are required before any major construction can start.

Low impact pre-construction activities, approved by the New South Wales Government in 2023 will continue in 2024. These include service utility relocations and site investigations, such as geotechnical surveys, to better understand ground conditions.

We will also continue acquiring land needed for the Inland Rail corridor and refining the construction scope and detailed design to provide greater certainty on N2N project’s cost and schedule.

Once we have completed this work and can demonstrate a robust cost estimate to the Australian Government, we will seek agreement to release construction packages for tender to the market.

Building Inland Rail’s longest stretch of new rail corridor will involve millions of cubic meters of earthworks for new embankments, the installation of thousands of culverts, road realignments and utility relocations. The current design features 12 active and 51 passive level crossings, 75 new bridges and viaducts and seven crossing loops, each up to 2.2km long.

Bridge over Wee Waa Road and Narrabri viaduct 3D fly-through


The northern section of the Narromine to Narrabri alignment will run west of Narrabri township. The section around Narrabri will be constructed on a 4km long concrete viaduct and will cross The Island Road, Narrabri Creek, Naomi River and Wee Waa Road before joining the Turrawan Line north of Narrabri.

This animated visualisation begins with a driver’s perspective, travelling west along Wee Waa Road (also known as the Kamilaroi Highway) and under the viaduct, before taking flight and showing the section around Narrabri from the air.

This visualisation is an indicative representation and is for illustration purposes only. It should not be considered the final design, which will be subject to change due to detailed design refinements.

The four Narromine to Narrabri fly-through videos include the proposed rail alignment, bridges, cuttings and embankments, and public crossings.

Please note that the reference design may change as a result of further investigations, government approvals, or during the detailed design phase.

Details on fencing, maintenance access roads or potential changes to level crossings are not included in the fly-through videos.
