The 28km Gowrie to Helidon section of Inland Rail 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, and 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.

This project is currently in the reference design stage. During this time, we are conducting various studies and consulting with landowners and other key stakeholders to finalise plans for this project. This technically complex section of Inland Rail will be delivered using a Public Private Partnership funding arrangement.
