Completed in mid-2013, the Hay Point Rail Expansion Project now services 30 coal mines in the northern Bowen Basin as the final leg of the 924km Goonyella Rail System. Coal is railed to the Port of Hay Point (40km south of Mackay) where it is exported through the Hay Point Coal Terminal (HPCT), operated by the BHP Billiton Mitsubishi Alliance (BMA) and the Dalrymple Bay Coal Terminal (DBCT), operated by DBCT Management.
Construction of the Wotonga Feeder Station commenced in early 2013 as part of the Goonyella Rail Expansion Project. The TrackPower Alliance completed construction in early 2014 and the substation was commissioned in April as a TSC. The Wotonga Feeder Station includes Track Sectioning Cabins (TSC) at Carborough Downs and Grosvenor to, increase the traction power capacity on the northern and western Goonyella lines.
In January 2014, Powerlink commenced construction of the 132 kV substation connecting the Wotonga Feeder Station to the Transmission Network. This was completed in mid 2015.
