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

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.
