It services the coal mining area of the Bowen Basin, carrying coal to the Hay Point and Dalrymple Bay Coal Terminals 20 km southeast of Mackay, as well as products to other destinations by way of connections to the North Coast Line at Yukan and the Central Line at Burngrove via the Gregory coal mine branch. It is also connected to the coal loading terminal at Abbot Point by the GAP line. The line opened on 5 November 1971 and runs for 477 kilometres. The Goonyella system is narrow gauge 1,067 mm and electrified using 25 kV 50 Hz. The line has been duplicated from Hay Point to Wotonga (174 km) and features CTC signalling over the entire system.
