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
Watch a fly-through of the project
Get a birds-eye view of the Gowrie to Helidon project. This video shows the alignment as of August 2019. The fly-through video is for illustration purposes and for discussion and community consultation.
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.
Six Mile Creek viaduct
This visualisation provides a three-dimensional view of the project’s Six Mile Creek viaduct reference design. This viaduct is the highest of the 13 bridge and viaduct structures that we expect to build for the project. It stands approximately 50 metres tall at its highest point at Six Mile Creek—about the same height by which the Sydney Harbour Bridge clears the water.
The Six Mile Creek viaduct is also the second longest viaduct on the project, spanning 966 metres as it passes over the Toowoomba Bypass, Six Mile Creek, Gittens Road and generally mountainous terrain. The structure accommodates a single line running, at 80km/h.
This 3D visualisation is for illustration and discussion purposes only. The final design of the structure will be prepared at the detailed design stage.

Billy cart derby brings childhood memories to life again
The smell of bacon and egg burgers, coffee, essential oils and soaps aren’t the only things that get our teams excited to be up with the birds on local market days. We enjoy catching up with our communities at these events.
