OPR is designing a strategic rail corridor from Oakajee to mines to the north east at Weld Range and Jack Hills under the exclusive development rights granted by the State Development Agreement. This corridor will also permit spur lines from the mines to the south east in the Karara and Koolanooka areas to also interconnect to Oakajee when required. Other spur lines have been investigated such as Weld Range to West Wiluna.The railway to Weld Range and Jack Hills has a length of about 520km.

The Proposed 560 km rail development linking Jack Hills and future iron ore mines of the mid-west to the Oakajee Port was referred to the EPA on 16th October, 2009. The level of assessment has been set at a Public Environmental Review with a 4 week public review period.

ecologia has completed the initial flora and fauna investigations along rail route, and the environmental impact assessment is anticipated to be complete by the end of December 2009.
