After identifying commercial opportunities in the Queensland market for the haulage of coal on the Goonyella rail system to the Port of Hay Point in 2010, Pacific National proposed the construction of a train provisioning and maintenance facility approximately 10 kilometers (6.2 miles) south of Nebo. This facility is purpose built to support the operations of locomotives and rolling stock.

Pacific National operates bulk and intermodal services throughout Australia and commenced rail operations on Queensland's North Coast Line in 2005. Pacific National also transport export coal to the Dalrymple Bay Coal Terminal, Abbot Point Coal Export Terminal and the Port of Gladstone.

Tetra Tech was engaged by BG&E as part of the Pacific National Infrastructure Alliance to provide engineering services. Tetra Tech utilized full 3D modelling and GPS positioning of equipment. The Pacific National Infrastructure Alliance consisted of Pacific National, QR National, Abigroup, and BG&E Consulting Engineers.

With the capacity to handle up to 25 coal trains over a year, the new facilities enable the provisioning and maintenance of Pacific National trains to ensure reliable and efficient operation, including the refueling of trains, routine train inspections, and wagon and locomotive maintenance work.

Planning for the project included consultation with key stakeholders across politics, industry, and community members to ensure minimal environmental, noise, and land impacts.

Tetra Tech’s designs ensured the innovative implementation of harvesting and recycling of up to 85 percent of water captured on the site.
