Works and planning

The Gowrie to Helidon section of Inland Rail will be built predominantly within the existing rail corridor and the Department of Transport and Main Roads’ Gowrie to Grandchester protected rail corridor. A study area was identified and refinements considered as part of the reference design process.

Work is expected to include building:

  • 28km of new dual gauge track
  • a 6.2km long tunnel (approximately)
  • 13 bridge and viaduct structures (6.7km in total length)
  • three crossing loops

Visualisations

To get a sense of what your community will look like after the project has been completed, check out our visualisations of the proposed design.

Visualisations are for illustrative purposes and not to scale.

Toowoomba Range tunnel

This visualisation provides a three-dimensional view of the Inland Rail Gowrie to Helidon project’s indicative Toowoomba tunnel reference design. The visualisation demonstrates the approach to tunnel safety and ventilation, including the safety provisions within the tunnel, water tanks, pump buildings, backup generator, transformer yard, access roads, tunnel portal, ventilation shaft and ventilation buildings.

This 3D visualisation is for illustration and discussion purposes only. The final design of the tunnel will be prepared at the detailed design stage.

Discover how we propose to deliver a fast and safe alignment down to the Lockyer Valley floor using viaduct structures and providing safe road/rail interfaces.

In 2017, the Australian Government confirmed a Public Private Partnership (PPP) model would be used to deliver this project as part of the Gowrie to Kagaru section of Inland Rail.
